Updates to Cryptocurrency/Crypto-mining News and Resources

FireEye: RIG Exploit Kit Delivering Monero Miner Via PROPagate Injection Technique

The Register: – How polite: Fun-bucks coin miners graciously ease off CPU pounding “…according to Johannes Ullrich, head of research at SANS, who today pointed out that malicious mining apps are scaling down activity and employing built-in encryption to make them harder for antivirus packages to detect.”

Updates to Meltdown/Spectre and other chip-related resources

Catalin Cimpanu for Bleeping Computer: Some Spectre In-Browser Mitigations Can Be Defeated “According to research published by Aleph Security … researchers were able to put together proof-of-concept code that retrieves sensitive data from a browser’s protected memory … their PoC bypassed Spectre mitigations and retrieved data from browsers such as Edge, Chrome, and Safari.” (But not Firefox, apparently.)

21st April 2018 resource updates

Note that for reasons of time management I may have to start spacing these out more.

Updates to Anti-Social Media 

(1) Reuters: Exclusive: Facebook to put 1.5 billion users out of reach of new EU privacy law – “The previously unreported move, which Facebook confirmed to Reuters on Tuesday, shows the world’s largest online social network is keen to reduce its exposure to GDPR, which allows European regulators to fine companies for collecting or using personal data without users’ consent.” (HT to Artem Baranov)

(2) Steven Englehardt et al: No boundaries for Facebook data: third-party trackers abuse Facebook Login – “Today we report yet another type of surreptitious data collection by third-party scripts that we discovered: the exfiltration of personal identifiers from websites through “login with Facebook” and other such social login APIs. Specifically, we found two types of vulnerabilities:

  • seven third parties abuse websites’ access to Facebook user data
  • one third party uses its own Facebook “application” to track users around the web.”

Commentary from The Register: Facebook’s login-to-other-sites service lets scum slurp your stuff – “A security researcher has claimed it’s possible to extract user information from Facebook’s Login service, the tool that lets you sign into third-party sites with a Facebook ID.”

(3) Help Net: Researchers develop algorithm to detect fake users on social networks – “Ben-Gurion University of the Negev and University of Washington researchers have developed a new generic method to detect fake accounts on most types of social networks, including Facebook and Twitter.”

Paper is here: Generic anomalous vertices detection utilizing alink prediction algorithm

Commentary from The Register: Gang way! Compsci geeks coming through! AI engine can finger fakes on social networks – “Take note Twitter, Facebook et al, it’s really not that hard to weed out bots”

(4) Graham Cluley: Facebook pushes ahead with controversial facial recognition feature in Europe “Facebook uses facial recognition software to automatically match people in photos your friends upload with the other billions of images on Facebook’s servers in which you might appear.”

(5) Help Net: LocalBlox found leaking info on tens of millions of individuals – “The discovery was made by UpGuard researcher Chris Vickery, who stumbled upon the unsecured Amazon Web Services S3 bucket holding the data, bundled in a single, compressed file. When decompressed, it revealed 48 million records in a format that’s easy for anyone to peruse.”

Here’s the Upguard blog post.

And commentary from Graham Cluley for Hot for security: 48 million people put at risk after firm that scraped info from social networks left it exposed for anyone to download

(6) Sophos: Facebook: 3 reasons we’re tracking non-users – more light cast into the shadows by the House Energy and Commerce Committee’s questions to Mark Zuckerberg.

(7) The Guardian: Far More Than 87 Million Facebook Users Had Data Compromised by Cambridge Analytica

(8) Sophos: Google in hot water over privacy of Android apps for kids

(9) Tech Crunch: A flaw-by-flaw guide to Facebook’s new GDPR privacy changes
“Just click accept, ignore those settings”

(10) Brian Krebs: Is Facebook’s Anti-Abuse System Broken?

Ransomware in decline?

Iain Thompson for The Register: Good news, everyone: Ransomware declining. Bad news: Miscreants are turning to crypto-mining on infected PCs – Screw asking for digi-coins. Craft ’em on 500,000 computers

Well, I don’t have immediate access to current ransomware statistics, so I don’t know how significant this decline is, but I’ve certainly seen a dramatic drop in the amount of information specific to ransomware families. As there isn’t a lot of more generic commentary that says anything new (about how to protect yourself from ransomware, for instance), there’s probably going to be less ransomware-related content on this site.

As you may have noticed, I’ve already added a resource page related to Meltdown/Spectre CPU issues: whether I’ll add other pages (rather than one-off articles) in the near future depends on how the threatscape evolves in the next few weeks. And, as always, how well I manage my limited work time!
