AUSCERT Week in Review29 March 2018
Greetings,
As Thursday the 29th of March closes, there are a few things on the AUSCERT’s team’s mind.First and foremost is the two (2) days of AUSCERT Conference at the Gold Coast on Thursday May 30, and Friday June 1st. Equally important is that the registration for the AUSCERT tutorials that precede the conference is out and remember that tutorials are complimentary for anyone who holds a Full Conference Registration. You can find further information on each of the tutorials via https://conference.auscert.org.au/conference-program/ The conference is a big event but there is also another big event at the Gold Coast which may draw unwanted interest from spammers. This is the GC2018 Commonwealth Games. So making your users aware that spammers may make the most of events and craft emails in ways that entice them to open attachments or follow link, could be worth the while. And to make a difference, on the first hour of the last day of the week, instead of the last hour of the last day of the week, Drupal Core has a patch available where by they expect the PoC to come out “hours or days” after the disclosure. So I do hope you got the SMS from AUSCERT’s Bulletin service this morning.
As for news, here’s a summary (including excerpts) of some of the more interesting stories we’ve seen this week:

Title: Drupal Fixes Drupalgeddon2 Security Flaw That Allows Hackers to Take Over SitesURL: https://www.bleepingcomputer.com/news/security/drupal-fixes-drupalgeddon2-security-flaw-that-allows-hackers-to-take-over-sites/Date: March 28, 2018Author: Catalin Cimpanu
Excerpt:“The Drupal CMS team has fixed a highly critical security flaw that allows hackers to take over a site just by accessing an URL.Drupal site owners should immediately —and we mean right now— update their sites to Drupal 7.58 or Drupal 8.5.1, depending on the version they’re running.The Drupal team pre-announced today’s patches last week when it said “exploits might be developed within hours or days” after today’s disclosure”

Title: Don’t get hacked during the Games URL: https://www.technologydecisions.com.au/content/security/news/don-t-get-hacked-during-the-games-634148475Date: March 23, 2018 Author: Technology Decisions
Excerpt:“It is expected that the Gold Coast Commonwealth Games will attract high levels of cybercrime, with businesses urged to stay alert for the possibility…Potential attacks to be aware of during the 2018 Commonwealth Games include: o hacks through public Wi-Fi hotspots that will be available throughout the Games; o email-based spear phishing campaigns that trick people into divulging personal information or clicking on links that release malware into their systems; o hacked social media and business websites; o point-of-sale attacks that let cybercriminals obtain credit card details; o ransomware attacks that prey on the time-sensitive nature of Games-related activities to force victims to pay higher ransoms, fast; o fraudulent invoices and payment details.”“——-
Title: In-Browser Cryptojacking Is Getting Harder to DetectURL: https://www.bleepingcomputer.com/news/security/in-browser-cryptojacking-is-getting-harder-to-detect/Date: March 27, 2018Author: Catalin Cimpanu
Excerpt:“Cyber-criminals aren’t stupid. If you find a way to block their code, they’re going to find a way to around your block.That’s how it’s been for decades in the antivirus business, and this is exactly what’s happening right now on the in-browser cryptocurrency mining (cryptojacking) scene…”

Title: Intel CPUs Vulnerable to New ‘BranchScope’ AttackURL: https://www.securityweek.com/intel-cpus-vulnerable-new-branchscope-attackDate: March 27, 2018 Author: Eduard Kovacs
Excerpt:“Researchers have discovered a new side-channel attack method that can be launched against devices with Intel processors, and the patches released in response to the Spectre and Meltdown vulnerabilities might not prevent these types of attacks.The new attack, dubbed BranchScope, has been identified and demonstrated by a team of researchers from the College of William & Mary, University of California Riverside, Carnegie Mellon University in Qatar, and Binghamton University.”

Title: Crooks infiltrate Google Play with malware in QR reading utilitiesURL: https://nakedsecurity.sophos.com/2018/03/23/crooks-infiltrate-google-play-with-malware-lurking-in-qr-reading-utilities/Date: March 23, 2018Author: Paul Ducklin
Excerpt:“…First, the apps were, at least on the surface, what they claimed: six were QR code reading apps; one was a so-called “smart compass”.In other words, if you were just trying out apps for fun, or for a one-off purpose, you’d be inclined to judge them by their own descriptions.Second, the crooks didn’t fire up the adware part of their apps right away, lurking innocently for a few hours before unleashing a barrage of ads.Third, the adware part of each app was embedded in what looks at first sight like a standard Android programming library that was itself embedded in the app.”

Title: Thousands of etcd installations are currently leaking 750MB worth of passwords, keys, and sensitive data.URL: http://securityaffairs.co/wordpress/70611/hacking/etcd-installs-data-leak.htmlDate: March 25, 2018Author: Pierluigi Paganini
Excerpt:“Thousands of servers belonging to private businesses and organizations are leaking credentials and potentially sensitive data.It is quite easy for hackers to use the credentials to access the servers and steal sensitive data or use the machines to power cyber attacks.According to the researcher Giovanni Collazo, querying the popular Shodan search engine he found almost 2,300 servers exposed online that were running etcd, which is a distributed key value store that provides a reliable way to store data across a cluster of machines.”

Title: Facebook Collected Call and SMS Metadata From Some Users’ SmartphonesURL: https://www.bleepingcomputer.com/news/technology/facebook-collected-call-and-sms-metadata-from-some-users-smartphones/Date: March 24, 2018Author: Catalin Cimpanu
Excerpt:“Several Facebook users who downloaded an archive of their Facebook data in the wake of the Facebook-Cambridge Analytica scandal discovered this week that the social network’s mobile applications have been recording —in some cases— much more information than most people were expecting.
Logged information includes data on all phone calls made on the phone, the start time o each call, its duration, and the contact’s name. The Facebook app did not log phone calls to and from numbers not saved in the phone’s address book.”
