Last week, we published a timely scam, a malvertising campaign, the final section of the 2-part piece of a certain exploit kit, and a complex obfuscation method found on malware that can run on Android devices.
When news of a roller coaster crash in Staffordshire, England erupted, majority of Internet users and those tuned in on the television waited in horror as images of the incident followed by live feeds of the aftermath began popping in our screens. Unfortunately, scammers can easily use news like this against the genuinely curious. Our researchers found a fake YouTube video claiming to be a video of the incident.
Popcash, a prolific pop-under ad network, was found to be used by online criminals to lead Internet users to sites serving exploit kits, which is this case is Magnitude EK. This kit is know to push ransomware. Based from the sample we have, it pushes CryptoWall, a notable ransomware that heavily encrypts personal files, thus, locking out their owner.
At the end of May, we published part 1 of a post entitled "Unusual Exploit Kit Targets Chinese Users", wherein we talked about the basic behaviours of a certain exploit kit called Chinad that targets Chinese websites and its visitors. In part 2, our malware analysts discussed their findings of the kit's four (4) component files.
Lastly, our mobile experts discussed an obfuscation technique used by an Android malware that we detect as Trojan.Dropper.RealShell. Hint: It had something to do with a file having the .lock extension.
