Cybercriminals with their illegal motives combined with complex attack tactics are getting on the nerves of federal agencies, as well as security experts. Lately, two interesting changes in attack techniques deployed by TA551 and APT37 threat actor groups have come to the light. While TA551 has been found switching from Valak malware to IcedID trojan as part of its recent cyberattacks, APT37 leveraged the VBA decoding technique to hide RokRat trojan on impacted systems.

There’s more. Malware authors are now heavily relying on Golang-based Ezuri crypter and memory loader to make their code undetectable to antivirus software. The crypter, which is already in use for malware targeting Windows, is now being used for malware aiming to infiltrate Linux systems.

Top Breaches Reported in the Last 24 Hours

New attack tactic
Multiple malware authors are relying on Golang-based Ezuri crypter and memory loader to make their code undetectable to antivirus software. Although the tactic is widely used across Windows malware, threat actors now use Ezuri for infiltrating Linux environments.

TA551 shift from Valak to IcedID
The TA551 threat actor group, which is known for extensively using information-stealing malware families such as Ursnif and Valak, has switched to IcedID malware after mid-July, 2020. The infection chain starts with a malicious email that includes a password-protected zip archive. If a victim opens the archive, it causes the download of malicious macros that drop IcedID malware on systems.

RokRat trojan  
North Korean hacking group APT37 has been found using the RokRat trojan in a fresh wave of campaigns against the South Korean government. A VBA self decoding technique is being used to hide the malware on impacted systems.
