AUSCERT Week in Review for 21st June 2019

21 Jun 2019

AUSCERT Week in Review for 21st June 2019 Greetings, This week the Australian government performed an rm -rf to a top government cyber security position and zero days for both Firefox and Oracle Weblogic were dropped.Here’s a summary (including excerpts) of some of the more interesting stories we’ve seen this week: Title: Mozilla patches Firefox zero-day abused in the wildDate Published: 18 June 2019Author: Catalin CimpanuExcerpt: “The Mozilla team has released earlier today version 67.0.3 of the Firefox browser to address a critical vulnerability that is currently being abused in the wild. A type confusion vulnerability can occur when manipulating JavaScript objects due to issues in Array.pop, Mozilla engineers wrote in a security advisory posted today. ‘This can allow for an exploitable crash,’ they added. ‘We are aware of targeted attacks in the wild abusing this flaw.'” —–Title: Oracle patches another actively-exploited WebLogic zero-dayDate Published:  June 19, 2019URL: Author: Catalin CimpanuExcerpt: “Oracle released an out-of-band security update to fix a vulnerability in WebLogic servers that was being actively exploited in the real world to hijack users’ systems. Attacks using this vulnerability were first reported by Chinese security firm Knownsec 404 Team on June 15, last Saturday. The initial report from Knownsec claimed the attacks exploited a brand new WebLogic bug to bypass patches for a previous zero-day tracked as CVE-2019-2725 — which was also exploited in the wild for days in April before Oracle released an emergency security patch for that one as well.” —–Title: Home Affairs deletes top govt cyber advisor positionDate Published: 21 June 2019Author: MSRC TeamExcerpt:“Australia’s top government cyber security policy job has quietly disappeared from the Department of Home Affairs following the shock departure of former cyber tsar Alastair MacGibbon. The department’s most recently issued organisation chart reveals the national cyber security advisor role has been shredded and the wider cyber security policy function absorbed within its policy directorate. Orignally established as the Prime Minister’s special advisor on cyber security, the high profile  public-facing role was established within the PM’s department as part of the heavily publicised May 2016 national cyber security strategy.” —–Title: Critical Vulnerabilities Patched in Cisco SD-WAN, DNA Center ProductsDate Published: June 20, 2019 Author: Eduard Kovacs Excerpt: “Cisco on Wednesday released patches for several critical and high-severity vulnerabilities affecting its SD-WAN, DNA Center, TelePresence, StarOS, RV router, Prime Service Catalog, and Meeting Server products. According to Cisco, the Digital Network Architecture (DNA) Center is affected by a critical vulnerability that allows a network attacker to bypass authentication and access critical internal services. The company’s SD-WAN solution, specifically its command-line interface (CLI), is affected by a critical flaw that can be exploited by a local attacker to elevate privileges to root and change the system configuration.” —–Title: Samba Vulnerability Can Crash Active Directory ComponentsDate Published: 20 June 2019Author: Lonut LlascuExcerpt: “A couple of bugs in some versions of Samba software can help an attacker crash key processes on the network in charge of providing directory, application, and other services. The two vulnerabilities can be leveraged separately to crash the LDAP (Lightweight Directory Access Protocol) and the RPC (remote procedural call) server processes in Samba Active Directory Domain Controller, supported since version 4.0 of the software.” —– Here are this week’s noteworthy security bulletins:1) [ESB-2019.2230] Apache Tomcat: Denial of service – Remote/unauthenticated     Clients are able to cause server-side threads to block, eventually leading to thread exhaustion and a denial of service. 2) [ESB-2019.2225] Bind: Denial of service – Remote/unauthenticated   Bind could be made to crash if it received specially crafted network traffic. 3) [ESB-2019.2220] libvirt: Multiple vulnerabilities   Mulitple denial of service and code execution vulnerabilities found in libvirt.   Stay safe, stay patched and have a great weekend,Rameez Agnew

14 Jun 2019

AUSCERT Week in Review for 14th June 2019 Greetings, Happy Microsoft patch week!  An updated Windows computer is a happy Windows computer (and will make us happy too!) In other news, if you recall the Exim vulnerability we mentioned last week, it’s now being exploited in the wild so please patch as soon as you can! Here’s a summary (including excerpts) of some of the more interesting stories we’ve seen this week: Exim email servers are now under attackDate Published: 14/06/2019https://www.zdnet.com/article/exim-email-servers-are-now-under-attack/ Excerpt: “Exim servers, estimated to run nearly 57% of the internet’s email servers, are now under a heavy barrage of attacks from hacker groups trying to exploit a recent security flaw in order to take over vulnerable servers, ZDNet has learned. At least two hacker groups have been identified carrying out attacks, one operating from a public internet server, and one using a server located on the dark web.” —–RAMBleed (CVE-2019-0174)Date Published: 12/06/2019https://rambleed.com/ Excerpt: “RAMBleed is a side-channel attack that enables an attacker to read out physical memory belonging to other processes. The implications of violating arbitrary privilege boundaries are numerous, and vary in severity based on the other software running on the target machine. As an example, in our paper we demonstrate an attack against OpenSSH in which we use RAMBleed to leak a 2048 bit RSA key. However, RAMBleed can be used for reading other data as well.” —–Google decloaks Win-DoS bug before patch is releasedDate Published: 12/06/2019https://www.itnews.com.au/news/google-decloaks-win-dos-bug-before-patch-is-released-526549 Excerpt: “Google’s Project Zero security team has decided to reveal the details of a denial of service (DoS) bug in Windows, after Microsoft said it would provide a patch outside the 90-day disclosure deadline. Project Zero lifted the veil on the flaw, 91 days after it was disclosed to Microsoft. The bug is found in the Windows cryptographic application programming interface, affecting the SymCrypt library arithmetic routines, Project Zero researcher Tavis Ormandy said.” —– 8.4TB in email metadata exposed in university data leakDate Published: 10/06/2019https://www.zdnet.com/article/8-4tb-in-email-metadata-exposed-in-university-data-leak/ Excerpt: “An exposed database belonging to Shanghai Jiao Tong University exposed 8.4TB in email metadata after failing to implement basic authentication demands. As described on the Rainbowtabl.es security blog, Paine found the ElasticSearch database through a Shodan search. The open database contained 9.5 billion rows of data and was active at the time of discovery, given that its size increased from 7TB on May 23 to 8.4TB only a day later.” —-Project Svalbard: The Future of Have I Been PwnedDate Published: 11/06/2019https://www.troyhunt.com/project-svalbard-the-future-of-have-i-been-pwned/ Excerpt: “Back in April during a regular catchup with the folks at KPMG about some otherwise mundane financial stuff (I’ve met with advisers regularly as my own financial state became more complex), they suggested I have a chat with their Mergers and Acquisition (M&A) practice about finding a new home for HIBP. I was comfy doing that; we have a long relationship and they understand not just HIBP, but the broader spectrum of the cyber things I do day to day. It wasn’t a hard decision to make – I needed help and theyhad the right experience and the right expertise.” Here are this week’s noteworthy security bulletins: 1) ASB-2019.0156 – Microsoft Windows: Multiple vulnerabilitieshttps://portal.auscert.org.au/bulletins/ASB-2019.0156/ 2) ESB-2019.2084 – vim: Execute arbitrary code/commands – Remote with user interactionhttps://portal.auscert.org.au/bulletins/ESB-2019.2084/ 3) ESB-2019.2090 – Adobe Flash Player: Execute arbitrary code/commands – Remote with user interactionhttps://portal.auscert.org.au/bulletins/ESB-2019.2090/ 4) ESB-2019.2101 – Intel Microprocessors: Access privileged data – Existing accounthttps://portal.auscert.org.au/bulletins/ESB-2019.2101/ 5) ESB-2019.2102 – Cisco IOS XE Software Web UI: Cross-site request forgery – Remote with user interactionhttps://portal.auscert.org.au/bulletins/ESB-2019.2102/ Stay safe, stay patched and have a good weekend!

AUSCERT Week in Review for 7th June 2019

7 Jun 2019

AUSCERT Week in Review for 7th June 2019 Greetings, Another fun week has been and gone. Great to see many of you last week at the conference, and we hope you’ve settled back in to your daily roles. Notable news this week includes a critical vulnerability in the Exim mail transfer agent and the disclosure of a second major hack of the Australian National University. It’s an unconventional story: the bug in Exim was patched entirely by accident back in February, and so the release notes at the time did not include a security notice. Researchers from Qualys have since disclosed the vulnerability. If you run Exim (which roughly half of mail servers on the internet do), we advise updating to Exim 4.92. The fix will also be backported to minor versions down to 4.87 and made available by your OS providers in time. Here’s a summary (including excerpts) of some of the more interesting stories we’ve seen this week: AUSCERT2019: that’s a wrap!https://wordpress-admin.auscert.org.au/blog/2019-06-07-auscert2019-s-wrapDate published: 07/06/2019Author: Bek of AUSCERT“The annual AUSCERT Cyber Security Conference has wrapped up for another year. This industry-leading event was held across 4 days. More than 700 delegates heard from 50 speakers and attended an array of interactive workshops. They networked with industry professionals, learnt the latest and best practices in the cyber and information security industry, and some even got their hands on awesome prizes. Here’s a summary of conference highlights for those who couldn’t attend.” New RCE vulnerability impacts nearly half of the internet’s email servershttps://www.zdnet.com/article/new-rce-vulnerability-impacts-nearly-half-of-the-internets-email-servers/Date published: 05/06/2019Author: Catalin Cimpanu of ZDNet“A critical remote command execution (RCE) security flaw impacts over half of the Internet’s email servers, security researchers from Qualys have revealed today. The vulnerability was patched with the release of Exim 4.92, on February 10, 2019, but at the time the Exim team released v4.92, they didn’t know they fixed a major security hole.” ANU suffers second ‘significant’ hack in a yearhttps://www.itnews.com.au/news/anu-suffers-second-significant-hack-in-a-year-526123Date published: 04/06/2019Author: iTnews“The Australian National University has suffered a massive data breach with about 19 years of data accessed by an unknown attacker. It’s the second major attack against the ANU, which was also hit in mid-July last year. The university at the time blamed an advanced persistent threat but said the “significant” damage from that incident had been contained.” United States visa applicants now required to hand over social media usernameshttps://www.abc.net.au/news/2019-06-03/us-visa-applicants-to-hand-over-social-media-usernames/11172086Date published: 03/06/2019Author: ABC News“The State Department is now requiring nearly all applicants for US visas to submit their social media usernames, previous email addresses and phone numbers. It’s a vast expansion of the Trump administration’s enhanced screening of potential immigrants and visitors. The department says it has updated its immigrant and non-immigrant visa forms to request the additional information, including “social media identifiers”.” Google Cloud goes down, taking YouTube, Gmail, Snapchat and others with ithttps://www.zdnet.com/google-amp/article/google-cloud-goes-down-taking-youtube-gmail-snapchat-and-others-with-it/Date published: 03/06/2019Author: ZDNetExcerpt: “A mysterious outage has hit Google Cloud, one of the biggest cloud service providers on the internet, and thousands of sites have gone down as a result, including both Google and non-Google services. Affected companies include some of the biggest names around, such as Snapchat, Vimeo, Shopify, Discord, Pokemon GO; but also most of Google’s own services, like YouTube, Gmail, Google Search, G Suite, Hangouts, Google Drive, Google Docs, Google Nest, and others. In an extreme case of irony, according to a Google employee, the outage was so severe that it also took down internal tools Google engineers were using to communicate among each other about the outage, making recovery efforts even more difficult.” Noteworthy bulletins of the week: 1) ESB-2019.2018.2 – exim: Execute arbitrary commands – Remote/unauthenticated.https://portal.auscert.org.au/bulletins/ESB-2019.2018.2/ The above-mentioned exim vulnerability. 2) ESB-2019.2033 – IBM WebSphere Application Server: Multiple vulnerabilities.https://portal.auscert.org.au/bulletins/ESB-2019.2033/ IBM Java SDK is in many of their products, and so is WebSphere. Expect a steady trickle of other IBM products updating their internal WebSphere version. 3) ESB-2019.2017 – Python Django: Cross-site scripting.https://portal.auscert.org.au/bulletins/ESB-2019.2017/ We love Django and are glad to see it’s kept up to date from pesky human errors. 4) ASB-2019.0153 – Android: Multiple vulnerabilities.https://portal.auscert.org.au/bulletins/ASB-2019.0153/ You can expect Android patch level 2019-06-05 to reach your phone, tablet or ICS controller in two to infinity months.

AUSCERT Week in Review for 31st May 2019

31 May 2019

AUSCERT Week in Review for 31st May 2019 Greetings, As you may be aware, this week marked our 18th annual AUSCERT conference. It’s been another great week of talks, tutorials, events, meeting new people, and catching up with familiar faces. A big thank you to our membership team for another successful year – we get a behind-the-scenes view of just how much work they put in to make this all happen. Another big thank you to everyone who came to join us, it makes all the hard work in the lead up worthwhile. If you couldn’t make it this year, we’re sorry to have missed you, but don’t worry – there’s always AUSCERT2020! And not to detract from the celebrations, but just a friendly reminder to make sure your systems are patched against BlueKeep.   Here’s a summary (including excerpts) of some of the more interesting stories we’ve seen this week: Almost one million Windows systems vulnerable to BlueKeep (CVE-2019-0708)Date published: 28/05/2019 Author: ZDNetExcerpt: “Nearly one million Windows PCs are vulnerable to BlueKeep, a vulnerability in the Remote Desktop Protocol (RDP) service impacting older versions of the Windows OS. This number comes to put initial fears into context — that over seven million devices were in danger — although the danger remains present, as one million devices are still nothing to joke about.” Unpatched Flaw Affects All Docker Versions, Exploits Ready Date published: 28/05/2019Author: Bleeping ComputerExcerpt: “All versions of Docker are currently vulnerable to a race condition that could give an attacker both read and write access to any file on the host system. Proof-of-concept code has been released. The flaw is similar to CVE-2018-15664 and it offers a window of opportunity for hackers to modify resource paths after resolution but before the assigned program starts operating on the resource. This is known as a time-to-check-time-to-use (TOCTOU) type of bug.” How to protect your business against cyber crimeDate published: 28/05/2019Author: In DailyExcerpt: “The 2018/2019 BDO and AUSCERT Cyber Security Survey found data loss/theft of confidential information incidents rose by 78.68 per cent in 2018 compared to 2017. While this could be partially explained by the February 2018 introduction of mandatory reporting through the Notifiable Data Breaches (NDB) scheme, BDO Technology Advisory Partner Nick Kervin said cyber attacks continued to increase across the board and were changing in their form.” Australian tech unicorn Canva suffers security breachDate published: 24/05/2019Author: ZDNetExcerpt: “Canva, a Sydney-based startup that’s behind the eponymous graphic design service, was hacked earlier today, ZDNet has learned. Data for roughly 139 million users has been taken during the breach, according to the hacker, who tipped off ZDNet. Responsible for the breach is a hacker going online as GnosticPlayers. The hacker is infamous. Since February this year, he/she/they has put up for sale on the dark web the data of 932 million users, which he stole from 44 companies from all over the world.”   Here are this week’s noteworthy security bulletins: 1) ESB-2019.1894.2 – sqlite3: Execute arbitrary code/commands – Remote/unauthenticatedhttps://portal.auscert.org.au/bulletins/ESB-2019.1894.2/ sqlite3 is vulnerable to a use-after-free remote execution via a crafted SQL statement. 2) ESB-2019.1941 – drupal plugins multiple security vulnerabilitieshttps://portal.auscert.org.au/bulletins/ESB-2019.1941/ A number of Drupal modules have updated to fix a swath of vulnerabilities. 3) ESB-2019.1905 – gnome-desktop: Multiple vulnerabilitieshttps://portal.auscert.org.au/bulletins/ESB-2019.1905/ GNOME has patched a vulnerability where maliciously crafted images could execute code when thumbnailed.

AUSCERT Week in Review for 24th May 2019 AUSCERT Week in Review24 May 2019 Greetings! Discussion still raged this week about the potential threat of theMicrosoft BlueKeep vulnerability revealed last week. That Microsofttook the incredibly unusual decision of issuing patches for operatingsystems long ago end-of-lifed indicated how serious they considered thisissue. A number of researchers have suggested that it’s only a matter oftime until this vulnerability could be extensively exploited. If you haveany old Windows systems potentially exposed now is the time to patch them! And for everyone attending the AUSCERT conference next week we lookforward to seeing you there. We have fewer than 10 tickets left for theconference, so if you were thinking of coming, you better decide soon! Here’s a summary (including excerpts) of some of the more interestingstories we’ve seen this week:   Title: BlueKeep Remote Desktop Exploits Are Coming, Patch Now!Date Published: 20/05/2019Author: Bleeping ComputerExcerpt: “Security researchers have created exploits for the remote codeexecution vulnerability in Microsoft’s Remote Desktop Services, trackedas CVE-2019-0708 and dubbed BlueKeep, and hackers may not be far behind.While the vulnerability inspired some playful users to create fakeproof-of-concept code intended for rickrolling, it is no joke. As RemoteDesktop Services is commonly exposed to the public so that users cangain remote access to their internal computers, successful exploitationcould allow access to an entire network.” Title: ‘What he’s achieved is spectacular’: Worker wins landmark case over fingerprinting on the jobDate Published: 21/05/2019Author: ABC NewsExcerpt: “When Queensland sawmill worker Jeremy Lee refused to givehis fingerprints to his employer as part of a new work sign-in, hewasn’t just thinking about his privacy. It was a matter of ownership.“It’s my biometric data. It’s not appropriate for them to have it,” hetells RN’s The Law Report. For not agreeing to the new system, Mr Leewas sacked. What followed was a legal battle that delivered the firstunfair dismissal decision of its kind in Australia.” Title: Two more Microsoft zero-days uploaded on GitHubDate Published: 22/05/2019Author: ZDNETExcerpt: “A security researcher going online by the pseudonym ofSandboxEscaper has published today demo exploit code for two moreMicrosoft zero-days after releasing a similar fully-working exploit theday before. These two mark the sixth and seventh zero-days impactingMicrosoft products this security researcher has published in the pastten months, with the first four being released last year, and three overthe past two days.”   Alerts, Advisories and Updates:——————————-Title: ASB-2019.0152 – [Solaris] Xerox FreeFlow Print Server v8: Multiple vulnerabilitiesDate: 24 May 2019 Title: ASB-2019.0151 – [Win] Xerox FreeFlow Print Server v2(Windows 7): Multiple vulnerabilitiesDate: 24 May 2019 Title: ASB-2019.0150 – [Win][UNIX/Linux] Wireshark: Denial of service – Remote with user interactionDate: 23 May 2019 Title: ASB-2019.0149 – [Win] Intel Graphics Driver for Windows: Denial of service – Existing accountDate: 23 May 2019 Title: ASB-2019.0148 – [Win][UNIX/Linux] Intel CSME: Multiple vulnerabilitiesDate: 22 May 2019 Stay safe, stay patched, and have a good weekend!

AUSCERT Week in Review for 17th May 2019

17 May 2019

AUSCERT Week in Review for 17th May 2019 AUSCERT Week in Review17 May 2019 Greetings, Hoo boy, what a week! – This patch Tuesday, Microsoft gave us CVE-2019-0708, a remote code execution vulnerability in remote desktop services. An exploit could potentially propagate like a worm, so this was severe enough for Microsoft to release free updates to Windows XP and Server 2003. – Not to be outdone, Cisco released a flock of advisories this week, including a vulnerability which allows a persistent backdoor without physical access to the device. – WhatsApp has provided an update due to a vulnerability that allows spyware to be injected onto your phone. – And the pièce de résistance, Intel have announced four new microprocessor flaws which could allow unauthorised access to cached data. Here’s a summary (including excerpts) of some of the more interesting stories we’ve seen this week: Title: Prevent a worm by updating Remote Desktop ServicesDate published: 14/05/2019 URL: https://blogs.technet.microsoft.com/msrc/2019/05/14/prevent-a-worm-by-updating-remote-desktop-services-cve-2019-0708/Author: MSRC TeamExcerpt: “Today Microsoft released fixes for a critical Remote Code Execution vulnerability, CVE-2019-0708, in Remote Desktop Services – formerly known as Terminal Services – that affects some older versions of Windows. The Remote Desktop Protocol (RDP) itself is not vulnerable. This vulnerability is pre-authentication and requires no user interaction. In other words, the vulnerability is ‘wormable’, meaning that any future malware that exploits this vulnerability could propagate from vulnerable computer to vulnerable computer in a similar way as the WannaCry malware spread across the globe in 2017. While we have observed no exploitation of this vulnerability, it is highly likely that malicious actors will write an exploit for this vulnerability and incorporate it into their malware.” Title: MDS – Microarchitectural Data Sampling – CVE-2018-12130, CVE-2018-12126, CVE-2018-12127, and CVE-2019-11091 Date published: 14/05/2019URL: https://access.redhat.com/security/vulnerabilities/mdsAuthor: Red HatExcerpt: “Four new microprocessor flaws have been discovered, the most severe of which is rated by Red Hat Product Security as having an Important impact. These flaws, if exploited by an attacker with local shell access to a system, could allow data in the CPU’s cache to be exposed to unauthorized processes. While difficult to execute, a skilled attacker could use these flaws to read memory from a virtual or containerized instance, or the underlying host system. Red Hat has mitigations prepared for affected systems and has detailed steps customers should take as they evaluate their exposure risk and formulate their response.” Title: Thrangrycat flaw lets attackers plant persistent backdoors on Cisco gearDate published: 13/05/2019URL: https://www.zdnet.com/article/thrangrycat-flaw-lets-attackers-plant-persistent-backdoors-on-cisco-gear/Author: Catalin CimpanuExcerpt: “A vulnerability disclosed today allows hackers to plant persistent backdoors on Cisco gear, even over the Internet, with no physical access to vulnerable devices. Named Thrangrycat, the vulnerability impacts the Trust Anchor module (TAm), a proprietary hardware security chip part of Cisco gear since 2013.” Title: WhatsApp urges users to update app after discovering spyware vulnerability Date published: 14/05/2019 URL: https://www.theguardian.com/technology/2019/may/13/whatsapp-urges-users-to-upgrade-after-discovering-spyware-vulnerabilityAuthor: Julia Carrie WongExcerpt: “WhatsApp is encouraging users to update to the latest version of the app after discovering a vulnerability that allowed spyware to be injected into a user’s phone through the app’s phone call function. The spyware was developed by the Israeli cyber intelligence company NSO Group, according to the Financial Times, which first reported the vulnerability.” Title: Linux Kernel Prior to 5.0.8 Vulnerable to Remote Code ExecutionDate published: 13/05/2019URL: https://www.bleepingcomputer.com/news/security/linux-kernel-prior-to-508-vulnerable-to-remote-code-execution/Author: Sergiu GatlanExcerpt: “Linux machines running distributions powered by kernels prior to 5.0.8 are affected by a race condition vulnerability leading to a use after free, related to net namespace cleanup, exposing vulnerable systems to remote attacks” Here are this week’s noteworthy security bulletins: 1) ASB-2019.0137 – ALERT [Win] Microsoft Windows: Multiple vulnerabilitieshttps://portal.auscert.org.au/bulletins/ASB-2019.0137 Microsoft has released its monthly security patch update for the month of May 2019. 2) ASB-2019.0138 – ALERT [Win][UNIX/Linux][Appliance][Virtual] Intel CPU Microcode: Access privileged data – Existing accounthttps://portal.auscert.org.au/bulletins/ASB-2019.0138 Intel has published a security advisory disclosing RIDL and Fallout, new speculative-execution side-channel vulnerabilities in the vein of Spectre and Meltdown. 3) ESB-2019.1721 – [Win][Mac] Adobe Acrobat and Reader : Multiple vulnerabilitieshttps://portal.auscert.org.au/bulletins/ESB-2019.1721 Adobe has released security updates for Adobe Acrobat and Reader for Windows and macOS.

AUSCERT Week in Review for 10th May 2019 AUSCERT Week in Review10 May 2019 Greetings, The week kicked off with a certificate chain issue in Firefox, resulting inadd-ons being disabled and prevented new add-ons being installed. Mozillapromptly released a hotfix and have now corrected the issue in Firefox66.0.5 for Desktop and Android, and Firefox ESR 60.6.3. This week Red Hat released RHEL 8, so we’ve already started publishing thosebulletins for the early adopters. Finally to round out the week, an issue was found in the official Alpine LinuxDocker images. Since Dec 2015, a NULL password was set for the root account.Alpine Linux is popular for creating small linux containers. Users shouldexplicitly disable the root account for containers using the affected Dockerimages.

AUSCERT Week in Review for 3rd May 2019

3 May 2019

AUSCERT Week in Review for 3rd May 2019 Greetings, Updates to protect against a remote code execution with administration privilege vulnerability in Dell’s SupportAssist were announced this week (CVE-2019-3719). SupportAssist ,which checks software and hardware status, is typically preinstalled on Dell systems running Windows and therefore affects numerous systems. As Proof-of-Concept code has been made available, patching vulnerable Dell systems is critical. Here’s a summary (including excerpts) of some of the more interesting stories we’ve seen this week: Title: 2018/2019 Cyber Security Survey Results Date Published: 1/5/2019 Author: AUSCERT and BDO Australia Excerpt: “For the third year running, AUSCERT has teamed up with BDO to conduct an industry-wide survey on the state of cybersecurity. The results of our most recent survey have just been published. AUSCERT has long supported the concept of mandatory breach notification, and it is heartening to see evidence that organisations expected to comply with at least one data breach regulation (GDPR, AU NDB) spend approximately 20% more on information security controls. It is also encouraging to observe the Cyber Security Survey’s finding that leadership awareness has increased. This concurs with AUSCERT’s own experience of more regular engagement at higher levels within organisations, such as CISOs and CIOs at other universities, and Principal Advisors / CISOs within state governments.” — Title: Docker Hub Database Hack Exposes Sensitive Data of 190K Users Date Published: 26/4/2019 Author: Bleeping Computer Excerpt: “An unauthorized person gained access to a Docker Hub database that exposed sensitive information for approximately 190,000 users. This information included some usernames and hashed passwords, as well as tokens for GitHub and Bitbucket repositories.” Title: Dell laptops and computers vulnerable to remote hijacks Date Published: 1/5/2019 Author: ZDNet Excerpt: “A vulnerability [CVE-2019-3719] in the Dell SupportAssist utility exposes Dell laptops and personal computers to a remote attack that can allow hackers to execute code with admin privileges on devices using an older version of this tool and take over users’ systems.” Stay safe, stay patched and have a good weekend, Eric

I will continue to devote my time to keeping people safe from malware attacks.””—– Title: Another dark web marketplace bites the dust — Wall Street MarketDate Published: 23/4/2019Author: ZDNetExcerpt: “Less than a month after the oldest and biggest dark web marketplace announced plans to shut down, another dark web market has “exit scammed” after the site’s admins ran away with over $14.2 million in user funds. Some of the market’s customer support staff are now blackmailing WSM customers. Staffers are asking for 0.05 Bitcoin (~$280) from vendors and customers who shared their Bitcoin address in support requests, threatening to share the address with law enforcement unless users pay the requested fee. And just as we were writing this article, the same moderator who was extorting WSM users took things to another level by sharing their mod account credentials online, allowing anyone – including law enforcement – to access the WSM backend, which may contain details about buyers and sellers’ real identities.”—– Title: Windows 7 Now Showing End of Support WarningsDate Published: 22/4/2019Author: BleepingComputerExcerpt: “Microsoft has started to display alerts in Windows 7 stating that the operating system will reach end of support on January 14, 2020. This alert links to a page that then recommends users upgrade to Windows 10. On January 14th, 2020, Windows 7 will officially reach end of support and Microsoft will no longer offer free security updates and technical support for the operating system.”—– Title: Another European manufacturer crippled by ransomwareDate Published: 25/4/2019Author: HelpNet SecurityExcerpt: ““Due to an IT system failure, the Aebi Schmidt Group can temporarily neither receive nor send emails,” the company announced on Thursday. “The IT system failure is due to an attempt by third parties to infiltrate malware into our systems. More and more companies worldwide are being affected by such attacks.””—– Here are this week’s noteworthy security bulletins: 1) ESB-2019.1408 – [Win][UNIX/Linux] BIND: Denial of service – Remote/unauthenticated Multiple Denial of Service vulnerabilities have been patched in BIND. 2) ESB-2019.1412 – [Win][UNIX/Linux] Atlassian Confluence Server and Data Center: Multiple vulnerabilities Confluence Server and Data Center had a path traversal vulnerability in the downloadallattachments resource.
