Description
A new attack technique called InstallFix targets users by cloning popular developer tool installation pages and presenting malicious install commands. Attackers distribute these fake pages through Google Ads, exploiting users' trust in familiar 'curl to bash' installation methods. The campaign specifically targets Claude Code users, delivering the Amatera Stealer malware. This technique bypasses email security controls and exploits the growing trend of non-technical users adopting developer tools. The attack leverages legitimate hosting services and is part of a broader trend targeting AI-related tools. The payload uses staged execution and various evasion techniques to avoid detection.
