Show ▼
The AMOS infostealer is being distributed through Google search ads that steer macOS users into poisoned ChatGPT and Grok conversations, creating a fresh path to credential theft and remote execution risk. The lure disguises malicious steps as helpful troubleshooting guidance. Victims who follow the commands can end up downloading and running the malware with root-level privileges. The campaign matters because it combines trusted search, legitimate AI chat surfaces, and a macOS-focused infostealer to increase success against everyday users.

A MacSync macOS infostealer campaign is abusing Google Ads and legitimate Claude.ai shared chats to lure users searching for "Claude mac download" into following Terminal instructions that download and run malware on their Mac. One observed variant uses polymorphic delivery, checks for Russian or CIS-region keyboard input sources and sends a cis_blocked ping before exiting, then profiles the victim with external IP address, hostname, OS version, and keyboard locale before using osascript to run a second-stage payload; another variant skips profiling and exfiltrates browser credentials, cookies, and macOS Keychain contents.

Kaspersky spots AMOS campaign via poisoned ChatGPT and Grok guides
Initial DisclosureKaspersky researchers first spotted a ClickFix campaign that abuses Google search ads to steer macOS users into poisoned ChatGPT and Grok conversations, and Huntress later confirmed widespread poisoning across troubleshooting queries such as "how to clear data on iMac" and "free up storage on Mac." The lure sends users to a base64-encoded URL that decodes into a bash script named update, shows a fake password prompt, and can download the AMOS infostealer with root-level privileges on macOS.
