The Scarab ransomware was discovered in June 2017. Since then, several variants have been created and discovered in the wild. The most popular or widespread versions were distributed via the Necurs botnet and initially written in Visual C compiled. However, after unpacking, we’ve found that another variant discovered in December 2017, called Scarabey, is distributed a little differently, with a different payload code as well. Scarabey, like most ransomware, is designed to demand a Bitcoin payment from its victims after encrypting files on their systems. However, instead of being distributed via Necurs malspam like the original Scarab, Scarabey was found targeting Russian users and being distributed via RDP/manual dropping on servers and systems. In addition, Scarabey seems to not be packed in any samples we have come across. The malicious code is written in Delphi without the C++ packaging that Scarab has and the content and language of the ransom notes are different for eac...

This post was authored by Vasilios Hioueras and Jérôme Segura Late last week saw the appearance of a new ransomware called GandCrab. Surprisingly, it is distributed via two exploit kits: RIG EK and GrandSoft EK. Why is this surprising? Other than Magnitude EK, which is known to consistently push the Magniber ransomware , other exploit kits have this year mostly dropped other payloads, such as Ramnit or SmokeLoader, typically followed by RATs and coin miners. Despite a bit of a slowdown in ransomware growth towards the last quarter of 2017, it remains a tried and tested business that guarantees threat actors a substantial source of revenue.

“Close. Close. Close. Close ,” my mother mumbles as she aggressively clicks her mouse over and over. “What’s wrong, Ma?” I’m home for the holidays, and cozy, cold evenings are often spent in front of the fireplace.

Earlier this morning, we published a protection update that caused connection issues for many of our customers. As a side effect of the web protection blocks, the product also spiked memory usage and possibly caused a crash.

Lenovo said nearly a dozen ThinkPad and ThinkCentre laptops contain a hardcoded password flaw.

I’ve been giving talks on the possible problems raised by virtual/augmented/mixed reality for a while now, and sure enough, we have what may be one of the first potentially major security issues thrown up by an in-the-wild application. Until a recent fix was applied, users of the pornography app SinVR could have found their subscriber information up for grabs. Researchers over at Digital Interruption discovered names, email addresses, and device names for anyone with an account alongside those paying for content using PayPal. This information would be great for social engineering, fake SinVR emails, or just plain old blackmail/embarrassment antics should any attacker be so inclined. They figured this out because while reversing the app, they realised they could make unauthenticated calls to endpoints, thanks to a function which looked as though it allowed SinVR to download a list of all users. Though they would have had to modify the binary to do this via the app, their web API...
