Beware: MetaStealer Malware Targets Apple macOS in Recent Attacks
2023-09-12 06:13

A new information stealer malware called MetaStealer has set its sights on Apple macOS, making the latest in a growing list of stealer families focused on the operating system after Stealer, Pureland, Atomic Stealer, and Realst.

"Threat actors are proactively targeting macOS businesses by posing as fake clients in order to socially engineer victims into launching malicious payloads," SentinelOne security researcher Phil Stokes said in a Monday analysis.

In these attacks, MetaStealer is distributed in the form of rogue application bundles in the disk image format, with targets approached through threat actors posing as prospective design clients in order to share a password-protected ZIP archive containing the DMG file.

SentinelOne said it observed some MetaStealer variants impersonating TradingView, the same tactic that has been adopted by Atomic Stealer in recent weeks.

"The appearance of yet another macOS infostealer this year shows the trend towards targeting Mac users for their data continues to rise in popularity among threat actors," Stokes said.

"What makes MetaStealer notable among this crop of recent malware is the clear targeting of business users and the objective of exfiltrating valuable keychain and other information from these targets. Such high-value data can be used to pursue further cybercriminal activity or gain a foothold in a larger business network."
