CERBER is a ransomware family which has adopted a new technique to make itself harder to detect: it is now using a new loader which appears to be designed to evade detection by machine learning solutions. This loader is designed to hollow out a normal process where the code of CERBER is instead run.Read More
CERBER is a ransomware family that has seen its share of unusual features since its appearance early last year. From its use of audio warnings, to the targeting of cloud platforms and databases, to distribution via malvertising, emailed scripting files, and exploit kits, CERBER has always been willing to keep up with the times, as it was. One reason for its apparent popularity may be the fact that it is sold in the Russian underground, giving a wide variety of cybercriminals access to it.
However, we’ve started seeing CERBER variants (which we detect as RANSOM_CERBER.F117AK) add a new wrinkle to their behavior: they have gone out of their way to avoid encrypting security software. How did they do this?Read More
In early December, GoldenEye ransomware (detected by Trend Micro as RANSOM_GOLDENEYE.A) was observed targeting German-speaking users—particularly those belonging to the human resource department. GoldenEye, a relabeled version of the Petya (RANSOM_PETYA) and Mischa (RANSOM_MISCHA) ransomware combo, not only kept to the James Bond theme of its earlier iteration, but also its attack vector.
Given ransomware’s likely outlook to reach a plateau, persistence in the threat landscape and diversification of target victims are the names of the game. GoldenEye exemplifies bad guys trying to gain scale, leverage, and profit with rehashed malware.Read More
Possibly to maximize the earning potential of Cerber’s developers and their affiliates, the ransomware incorporated a routine with heavier impact to businesses: encrypting database files. These repositories of organized data enable businesses to store, retrieve, sort, analyze, and manage pertinent information. When utilized effectively they help maintain the organization’s efficiency, so holding these mission-critical files hostage can adversely affect the business’s operations and bottom line.
A known ransomware peddled as a turnkey service to budding cybercriminals, Cerber has metamorphosed into a myriad of versions throughout its lifecycle. It picked up more tricks along the way, some of which include integrating a DDoS component, using double-zipped Windows Script Files, and leveraging a cloud productivity platform, even serving as secondary payload for an information-stealing Trojan.Read More
We have tracked three malvertising campaigns and one compromised site campaign using Cerber ransomware after version 4.0 (detected as as Ransom_CERBER.DLGE) was released a month after version 3.0. More details of this latest iteration of Cerber are listed in a ransomware advertisement provided by security researcher Kafeine.Read More
