Ransomware have become such a big income earner for cybercriminals that every bad guy wants a piece of the pie. The result? More tech-savvy criminals are offering their services to newbies and cybercriminal wanna-bes in the form of do-it-yourself (DIY) kits—ransomware as a service (RaaS).Read More
Perhaps emboldened by the success of their peers, attackers have been releasing more ransomware families and variants with alarming frequency. The latest one added to the list is R980 (detected by Trend Micro as RANSOM_CRYPBEE.A).
R980 has been found to arrive via spam emails, or through compromised websites. Like Locky, Cerber and MIRCOP, spam emails carrying this ransomware contain documents embedded with a malicious macro (detected as W2KM_CRYPBEE.A) that is programmed to download R980 through a particular URL. From the time R980 was detected, there have been active connections to that URL since July 26th of this year.Read More
In the beginning of September, a sizeable spam campaign was detected distributing a new Locky variant. Locky is a notorious ransomware that was first detected in the early months of 2016 and has continued to evolve and spread through different methods, particularly spam mail. A thorough look at samples from recent campaigns shows that cybercriminals are using sophisticated distribution methods, affecting users in more than 70 countries.
In the specific campaigns discussed below, both Locky and the ransomware FakeGlobe were being distributed—but the two were rotated. The cybercriminals behind the campaign designed it so that clicking on a link from the spam email might deliver Locky one hour, and then FakeGlobe the next. This makes re-infection a distinct possibility, as victims infected with one ransomware are still vulnerable to the next one in the rotation.Read More
The mobile threat landscape isn’t just rife with information stealers and rooting malware. There’s also mobile ransomware. While it seems they’re not as mature as their desktop counterparts, what with the likes of WannaCry and Petya, the increasing usage of mobile devices, particularly by businesses, will naturally draw more cybercriminal attention to this type of threat.
Take for instance mobile ransomware on the Android platform. The variants we detected and analyzed during the fourth quarter of last year were thrice as many compared to the same period in 2015. And indeed, the surge is staggering. We already had over 235,000 detections for Android mobile ransomware in the first half of 2017 alone—that’s 181% of detections for all of 2016.Read More
