The GlowComa threat actor is distributing ICMacOS, a macOS-targeted Malware-as-a-Service that has evolved from an information stealer into a persistent Remote Access Trojan (RAT).

The Phexia threat actor uses fake CAPTCHA 'ClickFix' lures to deploy a macOS backdoor that resolves its C2 hostname via a Polygon smart contract and drops multiple infostealers.

Adversaries are globally leveraging the ClickFix social engineering technique to trick Windows and macOS users into executing malicious terminal commands that deliver infostealers and RATs.

The XCSSET malware family has evolved to version 40, employing advanced in-memory execution, polymorphic payloads, and supply chain infection via poisoned Xcode projects targeting macOS developers.

A suspected North Korean cluster, linked to Sapphire Sleet, uses AppleScript to bypass macOS TCC protections and deploy the ptApp backdoor targeting cryptocurrency organizations.
