Lazarus group goes back to the Apple orchard with new macOS trojan | #CyberSecurity  | Apple, Mac, MacOS, iOS4, iPad, iPhone and (in)security... | Scoop.it

The Lazarus group, which has been named as one of North Korea's state-sponsored hacking teams, has been found to be using new tactics to infect macOS machines.

Dinesh_Devadoss, a threat analyst with anti-malware merchant K7 Computing, took credit for the discovery and reporting of what is believed to be the Lazarus group's first piece of in-memory malware on the Apple operating system.

In-memory infections, also known as fileless malware, operate entirely within the host machine's volatile RAM. This allows the software nasty to avoid setting off any antivirus systems that monitor files in storage or otherwise don't regularly scan all of system memory for threats

The malware sample found by Dinesh_Devadoss was dissected this week by Mac security guru Patrick Wardle, who says that the attack is a new spin on the classic Lazarus group tactic for slipping its malware onto the machines of unsuspecting users; by not installing any files during the secondary stage of the attack where the actual malicious activity occurs.
