Evading detection using new and sophisticated attack techniques is one of the primary goals of malicious actors. Recently, researchers have come across a new attack technique called ‘Module Stomping’ which is used to hide malicious code on a targeted system. The attack method involves overwriting the loaded modules with malicious code through cross-process memory injection.
New details regarding Electric Fish malware and Remcos trojan have also emerged in the past 24 hours. The US cyber command has publicly disclosed that the Electric Fish is linked to the North Korea-based APT38 hacking group. On the other hand, the new version of Remcos RAT is distributed via malicious .ace attachment through phishing emails.
In other developments, Mozilla has fixed a ‘master password’ security bypass flaw with the release of Firefox 68.0.2. The flaw could be exploited to steal stored login information by bypassing the master password of the built-in password manager.
