Google Ads Push MacOS AMOS Infostealer via ChatGPT & Grok AI Guides in 2024
In early June 2024, a threat campaign leveraged Google search advertisements to promote fraudulent ChatGPT and Grok chatbot guides targeting macOS users. Victims who clicked on these ads were redirected to malicious sites and deceived into downloading the AMOS (Atomic) infostealer malware, which harvested sensitive credentials, cryptocurrency wallets, and other private data. The campaign exemplifies the use of topical lures—capitalizing on the mainstream popularity of AI chat platforms—to facilitate widespread malware distribution, bypassing native macOS security. Attackers used SEO poisoning and social engineering tactics, making detection and attribution challenging, while infostealer payloads exfiltrated key business and personal data. This incident underscores a rising trend: infostealer campaigns exploiting interest in emerging AI technologies, with search engine ads and convincing guides serving as the primary attack vector. As macOS adoption grows in enterprises and AI tools become mainstream, businesses face escalating risks from social engineering, supply chain misuse, and evolving malware techniques exploiting trusted sites and brand searches.
