Atomic macOS Malware

Atomic info-stealer provides a full suite of data-stealing features, which allow for deeper penetration into the target system.

After executing the malicious dmg file, the malware displays a fake password entry window to obtain the system code and take control of the victim’s computer. Thus, the attacker can access sensitive information. However, a future update of the macOS Atomic malware might modify system settings or install additional malicious payloads.

After doing the above, the Atomic malware proceeds to extract information from software running on the compromised macOS machine, including the following:

However, malware must request permission to access these files. So, it might help the victims to get aware of the malicious activities.

When stealing data, the Atomic malware will bundle it into a single ZIP file and then send it to the threat actor’s command-and-control server, which Cyble claims is located at “Amos-malware [.]ru/sendlog”.

According to the Trellix researcher, the IP address associated with the threat actor’s command-and-control server and the build name are also used by Raccoon Thief, which indicates a possible link between the two malicious operations.

From there, the selected information and the ZIP file are also sent to the operator’s private Telegram channel.

macOS is often considered more secure than other operating systems. Nevertheless, Threat Actors (TA) have frequently targeted macOS platforms in recent years.
