Attackers using remote coding execution vulnerabilities to install cryptocurrency miners in vulnerable hosts

5 Jan 2018

Attackers using remote coding execution vulnerabilities to install cryptocurrency miners in vulnerable hosts Introduction Kicking off the New year, AUSCERT received reports of multiple attacks attempting to run exploits against vulnerable hosts in order to install and operate Cryptocurrency miners in them. Similar attacks have been reported around the globe. Sighted attacks so far have targeted hosts running Linux operating systems. The miners are dropped as ELF 64-bit files; these are Monero miners to be precise, and are variants of XMRig. [1] Alienvault released a pulse addressing Monero Miner installation attacks. [2] In one attack scenario, attackers exploited a Remote Code execution vulnerability in the WLS Security sub-component of the Oracle WebLogic Server (WLS) (CVE-2017-10271), to download and install Monero miner software in the target host. Weblogic Server versions vulnerable to this attack are 10.3.6.0.0, 12.1.3.0.0, 12.2.1.1.0 and 12.2.1.2.0. This vulnerability was addressed in Oracle CPU [3].  Two articles from nsfocusglobal and morihi-soc (translation required) provide some analyses into these attacks. [4,5]. AUSCERT performed its own analysis based on reports from multiple members. Indicators derived from that investigation have also been included in the list of indicators provided at the end of this blog. A new python-based cryptominer botnet has also been recently exposed. It uses a JBOSS vulnerability (CVE-2017-12149) to run remote code exploits against vulnerable Linux hosts to fetch base64 encoded python scripts and execute them.  These scripts in turn connect to remote Command and Control servers to fetch additional python scripts. Interestingly, this botnet appears to be using pastebin resources as C&C servers. [6]   Basic characteristics of an attack 1. Attackers launch a remote code execution exploit targeting one of the following vulnerabilities in the target host:     a. WebLogic server Remote Code Execution vulnerability. (CVE-2017-10271)    b. JBoss Remote Code Execution vulnerability (CVE-2017-7504, CVE-2017-12149: used by a new python-based crypto miner)    c. Apache Struts Jakarta Multipart parser Remote Code Execution vulnerability (CVE-2017-5638) 2. The exploit request includes the payload to fetch the cryptominer from a remote url create a crontab entry to make it run persistently and execute via the local shell depending on the operating system (e.g. cmd.exe for Windows and /bin/bash/ for Linux systems). 3. Additional Shell scripts are fetched from remote servers. These scripts have the function of:     a. Killing competing processes that consume large CPU loads (>20%)    b. Kill competing xmrig cryptocurrency mining processes    c. Create crontab entries and/or rc.local files to ensure the miner is executed at regular intervals or on system reboot    d. Modify file permissions to allow the miner to be executed by users with any privilege level    e. Generate log files     f. Communicate the miner’s execution progress to a remote HQ.    g. Determine the CPU type and number of CPU cores in a host and then branching to fetch an appropriate miner. 4.  The miner regularly communicates execution progress to a remote mining pool (or hq). Actual miner files carry different names based on the attack. AUSCERT has currently sighted miners as 64-bit ELF files with the following names:    a. fs-manager    b. sourplum    c. kworker    d. kworker_na Factors differentiating miners 1. Maximum CPU threshold.2. Dependence on an external config file. Some miner require an external config file (example, kworker.conf or config.json) to execute correctly. The config file typically contains:    a. The username and password to access the remote mining pool     b. URL of the remote mining pool    c. Mining algorithm used (e.g. Cryptonight)     d. the “nice” level of the mining process3. Homing to different HQs or mining pools Mitigation Recommendations 1. Patch systems against commonly targeted vulnerabilities for this type of attack. 2. Set ACLs and Firewalls to block outbound and inbound access to and from known Bitcoin mining pool IPs (unless your organisational policy allows the use of computing resources for bitcoin mining!). 3. Set IDS/IPS to detect requests and responses to and from payload delivery and network activity URLs. 4. Block resolution of domains known to be C&C and mining pools for cryptocurrency miners (e.g. via DNS firewalls). 5. Check Host files systems for dropped files (representing crypto miners) and corresponding hashes (e.g. using a Host-based IDS like OSSEC). See Indicators section below for a list of indicators of compromise.

5 Jan 2018

AUSCERT Week in Review for 5th January 2018 Greetings, Welcome back everyone! We hope that you all had a quiet and relaxing break since this first week of the year has been quite busy. Vulnerabilities (Meltdown and Spectre) in CPU hardware implementations have been disclosed and software mitigations are currently being released by all the major vendors. Please note that Microsoft, Mozilla and Google have confirmed that these vulnerabilities can be exploited through Internet Browsers.We have also observed attackers using remote coding execution vulnerabilities to install cryptocurrency miners in vulnerable hosts and more! Please don’t forget to put in your paper submission for the AUSCERT 2018 conference. Submissions close on the 19th. Here’s a summary (including excerpts) of some of the more interesting stories we’ve seen this week: Title: Forever 21 Suffered 7-Month POS Malware AttackDate Published: 3/1/2018URL: https://www.bankinfosecurity.com/forever-21-suffered-7-month-pos-malware-attack-a-10555Author: Mathew J. SchwartzExcerpt: “Apparel retailer Forever 21 says point-of-sale systems in some of its stores were infected by malware for up to seven months, compromising shoppers’ payment card data.”—– Title: Attention, vSphere VDP backup admins: There is a little remote root hole you need to patch…Date Published: 3/1/2018URL: https://www.theregister.co.uk/2018/01/03/vmware_vsphere_vdp/Author: Thomas ClaburnExcerpt: “VMware on Tuesday published a security advisory for its vSphere Data Protection (VDP) backup and recovery product. The virtualization giant identified three vulnerabilities, one of which it deems critical, with the two others categorized as important. The issues affect VDP 5.x, 6.0.x, and 6.1.x.”—– Title: US Homeland Security breach compromised personal info of 200,000+ staffDate Published: 4/1/2018URL: https://www.theregister.co.uk/2018/01/04/us_homeland_security_breach_exposed_personal_info_of_200000_staff/Author: Rebecca HillExcerpt: “More than 240,000 current and former employees of the US Department of Homeland Security have had their personal details exposed in a data breach. In what it describes somewhat euphemistically as a “privacy incident”, the DHS said the breach could also affect anyone who was part of an investigation by the DHS Office of Inspector General between 2002 and 2014.”—– Title: Apple confirms iPhone, Mac affected by Meltdown-Spectre vulnerabilitiesDate Published: 5/1/2018URL: http://www.zdnet.com/article/apple-confirms-iphone-mac-affected-by-meltdown-spectre-vulnerabilities/Author: Asha McLeanExcerpt: “Apple has issued a statement regarding the Meltdown and Spectre vulnerabilities, confirming all Mac systems and iOS devices are affected, but saying there are no known exploits impacting customers at this time. Apple, like Microsoft, has urged users to download software only from trusted sources, such as the App Store. “—– Here are this week’s noteworthy security bulletins: 1) ESB-2018.0011 – [Win][UNIX/Linux] phpMyAdmin: Cross-site request forgery – Remote with user interactionhttps://portal.auscert.org.au/bulletins/56474A CSRF vulnerability has been fixed in the latest version of phpMyAdmin. 2) ESB-2018.0038 – ALERT [Virtual] VMware vSphere Data Protection (VDP): Multiple vulnerabilitieshttps://portal.auscert.org.au/bulletins/56586A remote unauthenticated malicious user can potentially bypass application authentication and gain unauthorized root access to the affected systems. 3) ASB-2018.0002.3 – UPDATED ALERT [Win][UNIX/Linux] Intel CPU Chip: Access privileged data – Existing accounthttps://portal.auscert.org.au/bulletins/56602Side-channel attacks due to CPU Microcode errors allows for kernel memory to be accessed from user space. 4) ESB-2018.0049 – ALERT [Win] Microsoft Products: Access privileged data – Existing account https://portal.auscert.org.au/bulletins/56634Microsoft has released an out of band patch to fix the CPU Microcode vulnerabilities (Spectre/Meltdown) 5) ASB-2018.0006 – [Win][UNIX/Linux] Mozilla Firefox: Access privileged data – Remote with user interactionhttps://portal.auscert.org.au/bulletins/56726Mozilla has released an update to Firefox to mitigate the Speculative execution side-channel attack (“Spectre”).

AUSCERT Week in Review for 22nd December 2017

22 Dec 2017

AUSCERT Week in Review for 22nd December 2017 Greetings, As 2017 draws to a close, we hope it’s been good to you and yours. AUSCERT news: The Call for Proposals is still open until January 19th for the AUSCERT 2018 conference. We analysed the 1.4-billion-credential breach compilation this week and notified ~90% of our members of new user credentials appearing online. Didn’t get an email? Congratulations! AUSCERT will be going into “holiday mode” from today until the 2nd of January. We will continue to operate the 24/7 member incident hotline.(That number is available to members who log in at https://wordpress-admin.auscert.org.au/contact). We’ve become a Fairy Penguin sponsor of linux.conf.au 2018. This week in cybersecurity: ——————————————————————————-Unsecured Amazon S3 Bucket Exposes Details on 123 Million American Householdshttps://www.bleepingcomputer.com/news/security/unsecured-amazon-s3-bucket-exposes-details-on-123-million-american-householdsDate: December 20 2017Author: Catalin Cimpanu Excerpt: More precisely, the database contained over 3.5 billion details for over 123 million American households. The data included both personally identifiable information such as addresses, home details, contact information, or homeowner ethnicity, but also financial details such as mortgage status, financial histories, and purchase behavior.——————————————————————————-Backdoor in Captcha Plugin Affects 300K WordPress Siteshttps://www.wordfence.com/blog/2017/12/backdoor-captcha-pluginDate: December 19 2017Author: Matt Barry Excerpt: If you have not read our previous post on Mason Soiza, I’d suggest you read that first, since he has a long history of buying WordPress plugins in order to place cloaked backlinks on his users’ sites. He then uses these backlinks to increase page rank in SERPs (Search Engine Results Pages) since only web crawlers such as Googlebot can read them.——————————————————————————-Fixing Data Breaches Part I: Educationhttps://www.troyhunt.com/fixing-data-breaches-part-1-educationDate: December 18 2017Author: Troy Hunt Excerpt: You know the old “prevention is better than cure” idiom? Nowhere is it truer than with data breaches and it’s the most logical place to start this series. The next 4 parts of “Fixing Data Breaches” are all about dealing with an incident once things go badly wrong, but let’s start by trying to stop that from happening in the first place.[Troy has published four articles so far of his five-part series, and they are worth reading.]——————————————————————————-U.S. declares North Korea carried out massive WannaCry cyberattackhttp://wapo.st/2yTFsPkDate: December 19 2017Author: Ellen Nakashima & Philip Rucker Excerpt: The Trump administration on Monday evening publicly acknowledged that North Korea was behind the WannaCry computer worm that affected more than 230,000 computers in more than 150 countries earlier this year.——————————————————————————- And lastly, here are this week’s most noteworthy security bulletins: 1. Chromium browser security updatehttps://portal.auscert.org.au/bulletins/56290 Chromium (and Chrome) 63.0.3239.108 address a flaw allowing a web page containing malicious content to cause Chromium to crash, execute arbitrary code, or disclose sensitive information when visited by the victim. 2. otrs2 security updatehttps://portal.auscert.org.au/bulletins/56198 Two vulnerabilities were discovered in the Open Ticket Request System which could result in information disclosure or the execution of arbitrary shell commands by logged-in agents. 3. Security vulnerabilities patched in VMWare productshttps://portal.auscert.org.au/bulletins/56322 Successful exploitation of this issue could result in a low privileged user gaining root level privileges over the appliance base OS.[note: multiple issues exist] 4. Apache vulnerability announced and patched in F5 Networks Productshttps://portal.auscert.org.au/bulletins/56386 Apache modules apache_auth_token_mod and mod_auth_f5_auth_token.cpp allow possible unauthenticated bruteforce on the em_server_ip authorization parameter to obtain which SSL client certificates used for mutual authentication between BIG-IQ or Enterprise Manager (EM) and managed BIG-IP devices.

Breach compilation notifications

21 Dec 2017

Breach compilation notifications On Tuesday 19th, AUSCERT notified a large number of members whose credentials had been found online. This is a regular service AUSCERT provides, but in this case it is a special event based on a large credential compilation. It contains 1.4 billion credentials. Original source.   FAQ How do I open this file? Suppose the file you’ve received is named me@mydomain.com.zip.asc. This is an encrypted zip file. You will need PGP software to decrypt the file, e.g. GPG. GPG4Win GUI: Open the file in Kleopatra and enter the decryption passphrase. If Kleopatra tells you “error retrieving audit log: decryption failed”, instead open a command prompt and follow the below instructions. GPG command-line: gpg me@mydomain.zip.asc and enter the decryption passphrase. This will create me@mydomain.com.zip. (note no “asc”) Then unzip the file. It contains one or more text files with the credentials we’ve found.   Where do I get the decryption passphrase? Access AUSCERT: Symmetric key decryption details and log in with your member account.   We can’t log in to the member portal. If you know your AUSCERT privileged contact/s in your organisation, please contact them for access. Otherwise, please contact auscert@auscert.org.au to begin regaining access. If you have two-factor authentication set up, recall that this is through a One-Time Password app and not an SMS.   Why does Windows say they’re COM or audio files? Individual files are named by the domain they correspond to. Some files end with ‘.com’, which Windows interprets as a command file, or ‘.au’, which Windows interprets as an audio file. We’ll send files with the ‘.txt’ extension in future. Please open all files in a text editor, such as WordPad or Notepad++.   Where did you get this data? AUSCERT found these credentials in a large collection online, which aggregates other data breaches. It is likely that your users’ credentials were stolen in other breaches such as LinkedIn (for instance, Have I Been Pwned lists famous breaches). Original source.   Have we been breached? It’s hard to say. The majority of the data will have come from attacks on other companies’ databases in the past. Some may be from phishing attacks directly against your users. With a data set this large, individual small attacks can be compiled into what looks like one more substantial attack. It is unlikely, but possible, that your organisation’s database is the source of these credentials. If any of these credentials were reused on internal company systems, and are still active, then there is the potential for them to be abused.   What do we do now? AUSCERT recommends ensuring these credentials are no longer valid within your organisation. Consider contacting users to advise they should change their password anywhere it’s still in use.

AUSCERT Week in Review for 15th December 2017

15 Dec 2017

AUSCERT Week in Review for 15th December 2017 Greetings, We’ve had a “big” week in a few ways: A huge credential dump aggregating previous dumps has hit the limelight. The defendants in the Mirai case, 2016’s largest botnet, have pleaded guilty. Also, a 19-year-old RSA vulnerability has returned as the ROBOT attack, affecting many notable networking vendors.    The AUSCERT Conference’s Call for Proposals is open. Important Dates for submission——————————13 Nov 2017 – (Monday) – Call for Presentations submissions open19 Jan 2018 – (Friday) – Call for Presentations submission deadline19 Feb 2018 – (Monday) – Notifications from Program Committee Conference Date—————29 May 2018 – 01 Jun 2018 | AUSCERT2018 Conference   As for more news, here’s a summary (including excerpts) of some of the more interesting stories we’ve seen this week: How a Dorm Room Minecraft Scam Brought Down the Internethttps://www.wired.com/story/mirai-botnet-minecraft-scam-brought-down-the-internetDate: December 13 2017Author: Garrett M. Graff Excerpt: Until then, a large DDoS attack was often considered to be 10 to 20 gigibits per second; vDOS had been overwhelming targets with attacks in the range of 50 Gbps. A follow-on Mirai attack against OVH hit around 901 Gbps. BrickerBot Author Retires Claiming to Have Bricked over 10 Million IoT Deviceshttps://www.bleepingcomputer.com/news/security/brickerbot-author-retires-claiming-to-have-bricked-over-10-million-iot-devices/Date: December 11 2017Author: Catalin Cimpanu Excerpt: In an email sent today to Bleeping Computer, The Janit0r announced his sudden retirement and explained why he reached this decision. I believe that the project has been a technical success, but I am now starting to worry that it is also having a deleterious effect on the public’s perception of the overall IoT threat. Researchers keep issuing high profile warnings about genuinely dangerous new botnets, and a few weeks or even days later they are all but gone. Sooner or later people are going to start questioning the credibility of the research and the seriousness of the situation. Extended Validation is Brokenhttps://stripe.ian.shDate: December 12 2017Author: Ian Carroll Excerpt: One question may be how practical this attack is for a real attacker who desires to phish someone. First, from incorporation to issuance of the EV certificate, I spent less than an hour of my time and about $177. $100 of this was to incorporate the company, and $77 was for the certificate. It took about 48 hours from incorporation to the issuance of the certificate. Game-changing attack on critical infrastructure site causes outagehttps://arstechnica.com/information-technology/2017/12/game-changing-attack-on-critical-infrastructure-site-causes-outage/Date: December 15 2017Author: Dan Goodin Excerpt: The accidental outage was likely the result of the Triconex SIS, or “safety instrumented system.” The SIS shut down operations when it experienced an error that occurred as the hackers were performing reconnaissance on the facility. Although the hackers were likely seeking the ability to cause physical damage inside the facility, the November shutdown was likely not deliberate. Variation of 19-Year-Old Cryptographic Attack Affects Facebook, PayPal, Othershttps://www.bleepingcomputer.com/news/security/variation-of-19-year-old-cryptographic-attack-affects-facebook-paypal-others/Date: 12 December 2017Author: Catalin Cimpanu Excerpt: The ROBOT research team say that despite this being a variation for a 19-year-old attack, 27 of the Alexa Top 100 websites are vulnerable to the ROBOT attack. Vulnerable sites include Facebook and PayPal. The ROBOT attack scientific paper includes a case study how the research team decrypted Facebook traffic. 1.4 Billion Clear Text Credentials Discovered in a Single Databasehttps://medium.com/4iqdelvedeep/1-4-billion-clear-text-credentials-discovered-in-a-single-database-3131d0a1ae14Date: December 9 2017Author: Julio Casal Excerpt: The 41GB dump was found on 5th December 2017 in an underground community forum. The database was recently updated with the last set of data inserted on 11/29/2017. The total amount of credentials (usernames/clear text password pairs) is 1,400,553,869.   And lastly, here are this week’s most noteworthy security bulletins: 1. ASB-2017.0217 – Remote code execution patched in Palo Alto firewallshttps://portal.auscert.org.au/bulletins/56182 Through the exploitation of a combination of unrelated vulnerabilities, and via the management interface of the device, an attacker could remotely execute code on PAN-OS in the context of the highest privileged user. 2. ESB-2017.3160 – Thunderbird security updatehttps://portal.auscert.org.au/bulletins/55970 Multiple security issues have been found in Thunderbird, which may lead to the execution of arbitrary code or denial of service. 3. ESB-2017.3200 – Jenkins patches race conditions during setuphttps://portal.auscert.org.au/bulletins/56154 On Jenkins 2.81 and newer, including LTS 2.89.1, this could in rare cases (we estimate less than 20% of new instances) result in failure to initialize the setup wizard on the first startup. Affected instances need to be configured to restrict access. 4. ESB-2017.3182.2 – TLS vulnerability discovered in Cisco products (ROBOT)https://portal.auscert.org.au/bulletins/56082 An attacker could iteratively query a server running a vulnerable TLS stack implementation to perform cryptanalytic operations that may allow decryption of previously captured TLS sessions. [Note that Cisco does not intend to fix this in all affected products, e.g.the ACE 4710 and ACE30.]   Wishing you all the best from AUSCERT and see you next week,David

APCERT 2017 AGM and Conference: A Window into the CERT community

21 Nov 2017

APCERT 2017 AGM and Conference: A Window into the CERT community Introduction This year’s APCERT Annual General Meeting and conference has just concluded, being hosted by CERT-In in New Delhi, India. Each year AUSCERT sends a representative to the APCERT conference to collaborate and cooperate with the rest of the APCERT community. This year, I was lucky enough to be selected to attend. APCERT is a community of CERT and CSIRT organisations located in the Asia-Pacific area. Originally formed in 2003, its membership has now grown to 30 organisations representing 21 economies, as well as a number of supporting partner organisations. APCERT’s goals include information sharing and cooperation between its members and the public. Arriving in New Delhi This was my first visit to India, and although I had some knowledge of Indian culture and life, I was amazed to experience it first-hand. I arrived one day before the conference began, and spent the day shopping and taking in the local sights. The bustling streets, chaotic traffic, and the sheer scale of the country are a sight to see, and offer a sharp contrast to the quiet suburban life I am used to back in Brisbane. Delhi itself is a massive city, with a population that rivals that of all of Australia. The conference itself was hosted at the Ashok hotel, in Chanakyapuri, New Delhi. This five-star hotel is located in the heart of a diplomatic and government district, close to many foreign embassies, and as a result is very accommodating to foreign guests. The APCERT Community When the conference registration opened on Sunday morning, I began meeting delegates from other APCERT members. I noticed immediately that everyone was friendly, relaxed, and very welcoming. The APCERT community is small and close-knit, and for some long-time members, the conferences are just as much of a catch-up session as they are a business trip. Apparently some of AUSCERT’s staff are quite famous in the APCERT community, as I received quite a few queries regarding some of my colleagues! All of the APCERT members are working towards the same goal – to protect their economies or industry sectors from new and existing cyber threats. As we are largely government-funded or non-profit organisations, there is no pressure to create profits or sell products, and the focus is entirely on providing the best possible service to our jurisdictions. Some of the teams that participate in APCERT are quite small and do not have the resources to analyse all new threats, so collaboration amongst teams is extremely beneficial. In addition to the welcoming atmosphere among APCERT members, the hospitality and kindness shown by CERT-In was second-to-none. This year was the first time they had hosted the APCERT conference, but the experience was extremely smooth and well-thought out. During the afternoon of the first day, we were taken on a guided tour of local sights by the CERT-In staff, before being presented with a welcome dinner. Having helped run the AUSCERT conference in the past, I know how difficult and stressful it can be to run such an event, and I commend CERT-In on their performance. Conference Proceedings and Talks The conference began with updates from the various working groups within APCERT. This is a great way to share progress with other members, and some of the work presented by teams this year was extremely impressive. One such example is the TSUBAME project, which collects network traffic data from passive “sensors” situated in many networks across the Asia-Pacific region, and compiles that data into statistics that can be used to observe trends in network scans across the internet. Other talks focused on issues such as automated malware analysis, in particular the need for non-commercial options that can be used with potentially sensitive information. A talk given by Wen-Ling Lo from TWCERT/CC brought up an excellent point: many people use services such as VirusTotal or VirScan to check suspicious email attachments, but if the attachment is legitimate and contains confidential information, uploading it to a commercial company’s services could result in an information leak. TWCERT/CC are currently developing a tool that can be used by businesses and governments in Taiwan to examine files without fear that samples will be sent to external or commercial companies. AUSCERT is very impressed with their efforts and will be tracking their progress closely. Not all talks were technical, though, and an unexpectedly impactful presentation by Nurul Husna of MyCERT, the national CERT for Malaysia, described the governance and management workflows required to operate a CERT efficiently. As a technical person, it was refreshing to see a presentation on governance that made sense and showed real value. There is a real need for efficient management of resources at CERTs, due to the quick turnaround time required in order to serve our jurisdictions effectively. Additionally, some external speakers were invited to give talks at the conference. Some highlights included a talk by Akamai representative Amol Mathur on attacks that target API services directly, bypassing many of the protections that are built into front-end applications, and an overview on using machine learning to analyse malware samples by Rajesh Nikam of Quick Heal. As malware campaigns grow in both size and number, we need to move away from manual analysis in order to process as many samples as possible, making use of technologies such as machine learning to automate the process. On the final day of the conference, attendance was opened to external members of the IT industry, and the National Minister for IT & Electronics gave an address to the audience. During the conference I began to see just how large and important the IT industry in India is. With a population of over 1 billion people, internet-based solutions are essential to interacting with the government and businesses, and ensuring these interactions are protected and non-fraudulent is a problem at the forefront of the industry. The conference also served as a focus point for the local government to draw attention to emerging threats, especially as they begin to move towards more digital payment solutions. The full schedule for the APCERT Annual General Meeting and Conference may be found here: https://apcert2017.in/schedule.html The APCERT AGM Another important part of the conference is the Annual General Meeting, or AGM. At the AGM, proposals for changes and amendments to APCERT frameworks and guidelines are put forward and voted upon by members. Proposals for new working groups are also heard, and lastly, the membership of the steering committee and leadership positions are voted upon. This year, CERT-In was accepted as a new member of the steering committee, and after recognising the hard work of JPCERT/CC, MyCERT, and CERT Australia in their positions as Secretariat, Deputy Chair, and Chair respectively, the members of APCERT voted to re-appoint them to their previous positions. AUSCERT would like to thank the steering committee and leadership positions for their hard work in the past year, and congratulate them on their continued appointments. We also welcome CERT-In to the steering committee and look forward to their input in the future! Closing Remarks Attending the APCERT conference and AGM was an eye-opening experience. In the fast-moving world of Information Security, we are facing attacks in greater numbers and greater complexity. It can be difficult to sift through the vast amounts of information distributed throughout the internet, trying to find advice that is truthful, accurate, and relevant to your organisation. CERT and CSIRT organisations offer an increasingly important role in these times, distributing threat intelligence efficiently and with the goal of national/sectorial security in mind. As well, the challenges faced by each CERT are often similar, and there is great value in being able to speak freely with other organisations that share your goals. I would like to thank all of the members, partners, and guests at the conference, for welcoming me to the APCERT community. I’ve made many new friends over the last week, and hearing other analysts describe their experiences, challenges and achievements has re-invigorated my love for information security. I hope AUSCERT can continue to provide value to other APCERT members and look forward to some new collaborations in the future.I would also like to offer a special thank-you to the staff of CERT-In, for being such hospitable hosts. My first stay in India was a great experience, and I hope to return in the future.   Anthony Vaccaroanthony@auscert.org.au

AUSCERT Week in Review for 10th November 2017 AUSCERT Week in Review10 November 2017 Greetings, As Friday 10th of November closes, DDE, a twenty four (24) year old feature in the Office suite, has taken the limelight in the method of executing code on victim’s computers.  Although this method requires heavy user interaction, it was finally addressed for mitigation, published by the vendor and pushed out to members in an AUSCERT bulletin. So, applying the mitigation and applying an other round of user education notices may do well to protect your organisation.  Another set of people that may need to be educated on the dangers of opening up fresh and untrusted code on the internet could be script kiddies, this being the lead to our top new story this week. As for more news, here’s a summary (including excerpts) of some of the more interesting stories we’ve seen this week: Title:  Script Kiddie Nightmare: IoT Attack Code Embedded with BackdoorURL:    https://blog.newskysecurity.com/script-kiddie-nightmare-iot-attack-code-embedded-with-backdoor-39ebcb92a4bbDate:   November 8, 2017 Author: NewSky Security     Excerpt:“The IoT threat landscape is proving to be the fastest to evolve, with attacks shifting from basic password guessing, to using a variety of exploits as seen recently in the IoTroop/Reaper botnet. Enter the script kiddie?—?amateurish hackers that copy/paste code for quick results. “ ——- Title:  Windows Movie Maker Scam spreads massively due to high Google rankingURL:    https://www.welivesecurity.com/2017/11/09/eset-detected-windows-movie-maker-scam-2017/Date:   November 9, 2017 Author: Peter Stancik     Excerpt:“Scammers have been surprisingly successful at distributing a modified version of Windows Movie Maker that aims to collect money from unaware users. The spread of the scam (which itself is far from new) has been boosted by search engine optimization of the crooks’ website, as well as continuing demand for Windows Movie Maker, Microsoft’s free video editing software, discontinued since January 2017.” ——- Title:  Google Adds New Features in Chrome to Fight MalvertisingURL:    https://www.bleepingcomputer.com/news/security/google-adds-new-features-in-chrome-to-fight-malvertising/Date:   November 9, 2017 Author: Catalin Cimpanu     Excerpt:“Google announced plans today for three new Chrome security features that will block websites from sneakily redirecting users to new URLs without the user or website owner’s consent. While all three additions are welcomed, one of these features has the potential to stop a few malvertising campaigns dead in their tracks, and could potentially disrupt the malware scene in the next few months.” ——- Title:  Chinese Keyboard Developer Spies on User Through Built-in KeyloggerURL:    https://www.hackread.com/chinese-keyboard-developer-spies-on-user-through-built-in-keylogger/Date:   November 8, 2017Author: Waqas      Excerpt:“A Chinese mechanical keyboard manufacturer MantisTek has been caught in the middle of a controversy in which it’s being blamed for spying on users through built-in keylogger in its GK2 model and sending the data to a server apparently hosted on Alibaba Cloud server.” ——- Title:  Locky Ransomware Used to Target Hospitals EvolvesURL:    http://www.zdnet.com/article/locky-ransomware-used-to-target-hospitals-evolves/Date:   November 7, 2017Author: Charlie Osborne     Excerpt:“According to new research released by Cylance, a relatively new Locky variant, dubbed Diablo6, includes a few tweaks which are making detection of the ransomware more difficult for traditional antivirus solutions as well as end users.In a blog post, the team said Diablo6 performs an attack in two stages. The first is a typical attack vector for ransomware — a spear phishing email which contains a .zip archive, but something new for the Locky variant.While masquerading as a legitimate email and attachment, the file actually contains a VBS file which, when decompressed and opened, attempts to connect to Locky’s command-and-control (C&C) server for instructions.” ——- And lastly, here are this week’s noteworthy security bulletins (in no particular order): 1.    ASB-2017.0192 – [Win] Securely opening Microsoft Office documents that contain Dynamic Data Exchange (DDE) fieldshttps://portal.auscert.org.au/bulletins/54686 An attacker could leverage the DDE protocol by sending a specially crafted file to the user and then convincing the user to open the file, typically by way of an enticement in an email. 2.    ESB-2017.2807 – [SUSE] kernel: Multiple vulnerabilitieshttps://portal.auscert.org.au/bulletins/54466 CVE-2015-9004: kernel/events/core.c in the Linux kernel mishandled counter grouping, which allowed local users to gain privileges via a crafted application, related to the perf_pmu_register and perf_event_open functions 3.    ESB-2017.2867 – [Appliance] IBM Security SiteProtector System: Multiple vulnerabilitieshttps://portal.auscert.org.au/bulletins/54726 CVE-2017-10116: An unspecified vulnerability related to the Java SE Security component could allow an unauthenticated attacker to take control of the system. 4.    ESB-2017.2865 – [Win] Schnedier Electric InduSoft Web Studio and Schneider Electric InTouch Machine Edition : Execute arbitrary code/commands – Remote/unauthenticatedhttps://portal.auscert.org.au/bulletins/54718 CVE-2017-14024: The stack-based buffer overflow vulnerability has been identified, which may allow remote code execution with high privileges. 5.    ESB-2017.2855 – [BlackBerry] BlackBerry: Multiple vulnerabilitieshttps://portal.auscert.org.au/bulletins/54670 CVE-2017-0862: Elevation of Privilege in Kernel                              — Wishing you the best from AUSCERT and hope to see you next week,Geoffroy

Week in review

AUSCERT Week in Review for 3rd November 2017

3 Nov 2017

AUSCERT Week in Review for 3rd November 2017 AUSCERT Week in Review03 November 2017 Greetings, As Friday 3rd of November closes, a tally of the root compromises is more than I have seen this past year.  Let’s hope that the reason why we are indeed seeing an up tick in this type of vulnerability is only because security teams and their capabilities are indeed expanding. Well, at least this is the silver lining to be seen as this cloud of root compromise bulletins rolls over.  As for news, here’s a summary (including excerpts) of some of the more interesting stories we’ve seen this week: Title:  If your websites use WordPress, put down that coffee and upgrade to 4.8.3. Thank us laterURL:    http://www.theregister.co.uk/2017/10/31/wordpress_security_fix_4_8_3/Date:   31st October 2017Author: Iain Thomson Excerpt:“The fix addresses a flaw that can be potentially exploited by hackers to hijack and take over WordPress-powered websites, by injecting malicious SQL database commands. The core installation of WordPress is not directly affected, we’re told, rather the bug is in a security function provided by the core to plugins and themes. In other words, a bug in the core leaves plugins and themes potentially at risk of being hacked, leading to whole sites being commandeered by miscreants.” ——- Title:  Just one day after its release, iOS 11.1 hacked by security researchersURL:    http://www.zdnet.com/article/ios-11-hacked-by-security-researchers-day-after-release/Date:   2nd November 2017Author: Zack Whittaker Excerpt:“A day after iOS 11.1 was released, security researchers have already broken the software. News of the exploits came from Trend Micro’s Mobile Pwn2Own contest in Tokyo, where security researchers found two vulnerabilities in Safari, the mobile operating system’s browser. “ ——- Title:  AI will not solve your security analytics issuesURL:    https://www.csoonline.com/article/3236025/artificial-intelligence/ai-will-not-solve-your-security-analytics-issues.htmlDate:   2nd November 2017Author: Alexander Poizner Excerpt:“Managing SOC is not pretty. Constant stress due to avalanche of tickets and vast amounts of data to analyze using often underpowered and sometimes outdated tools, combined with high turnover and low morale staff. It is understandable that in such environment everybody is looking for a miracle. Any new technology that has a capability to automate an analysis and detect anomalies gets attention of operations security. With an amount of hype surrounding AI, the temptation is great to jump into early adoption.” ——- Title:  Security Think Tank: Three areas of web security challengesURL:    http://www.computerweekly.com/opinion/Security-Think-Tank-Three-areas-of-web-security-challengesDate:   1st November 2017Author: Peter Wenham Excerpt:“Very few companies these days are without a website and those websites provide a portal from the internet that the bad people can exploit to attack a company’s infrastructure including the website itself. The security challenges posed by a web presence fall into the three broad categories of legal, technical and operational. On the legal side you need to have a privacy policy identifying what personal data is collected, how that data will be used and who that data might be shared with and why. The policy should be made compliant with the General Data Protection Regulation (GDPR) for which the compliance deadline is 25 May 2018, but this will require you to track GDPR guidance as it becomes available.” ——- Title:  Facebook pledges to double its 10,000-person safety and security staff by end of 2018URL:    https://www.cnbc.com/2017/10/31/facebook-senate-testimony-doubling-security-group-to-20000-in-2018.htmlDate:   31st October 2017Author: Anita Balakrishnan     Excerpt:“Facebook, under intensifying pressure from legislators and consumers to clean up its site, is pledging to double the number of people it has working on issues related to safety and security. Colin Stretch, a vice president and general counsel at Facebook, testified before senators on Tuesday alongside executives from Twitter and Google. He told them that Facebook’s staff focused on sensitive security and community issues will grow to 20,000 by the end of next year.” ——- And lastly, here are this week’s noteworthy security bulletins (in no particular order): 1.    ESB-2017.2778 – [OSX] Apple macOS: Multiple vulnerabilities https://portal.auscert.org.au/bulletins/54342 An application may be able to execute arbitrary code with system privileges. 2.    ESB-2017.2766 – [Mobile] Apple Watch: Multiple vulnerabilitieshttps://portal.auscert.org.au/bulletins/54294 An application may be able to execute arbitrary code with kernel privileges. 3.    ESB-2017.2763 – [Ubuntu] kernel: Multiple vulnerabilitieshttps://portal.auscert.org.au/bulletins/54282 A local attacker could exploit this vulnerability to cause a denial of service (system crash) or possibly execute arbitrary code with administrative privileges. 4.    ESB-2017.2782 – [Cisco] Cisco Firepower 4100 Series Next-Generation Firewall (NGFW): Root compromise – Existing accounthttps://portal.auscert.org.au/bulletins/54358 An authenticated, remote attacker to inject arbitrary commands that could be executed with root privileges. 5.    ESB-2017.2790 – [Appliance] F5 Products: Multiple vulnerabilitieshttps://portal.auscert.org.au/bulletins/54390 An authenticated attacker may be able to cause an escalation of privileges through a crafted application that uses the fork or close system call. — Wishing you the best from AUSCERT and hope to see you next week,Geoffroy
