We analyzed samples of EMOTET, URSNIF, DRIDEX and BitPaymer and found similar payload loaders and internal data structures, possibly implying that these different groups are familiar with and are working closely together.

Discovered by Trend Micro in 2014, the banking Trojan Emotet has been brought back to life by malware authors last year with its own spamming module that has allowed it to spread, target new industries and regions, and evade sandbox and malware analysis techniques. This year, we examined Emotet’s activities to learn more about how this modular malware wreaks havoc: We did a comprehensive research on Emotet’s artifacts — 8,528 unique URLs, 5,849 document droppers, and 571 executables collected between June 1, 2018 and September 15, 2018 — to discover Emotet’s infrastructure as well as possible attribution information.

We discussed the re-emergence of banking malware EMOTET in September and how it has adopted a wider scope since it wasn’t picky about the industries it attacks. We recently discovered that EMOTET has a new iteration (detected as TSPY_EMOTET.SMD10) with a few changes in its usual behavior and new routines that allow it to elude…
Read More We first detected the banking malware EMOTET back in 2014, we looked into the banking malware’s routines and behaviors and took note of its information stealing abilities via network sniffing. After a period of relative inactivity, it appears it’s making a comeback with increased activity from new variants that have the potential to unleash different types of payloads in the affected system.

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.
