ClickFix Campaigns Expand, Using AI Tools as a Convincing Lure

Summary
Push and other researchers report growing ClickFix activity, including fake AI-tool installers and malicious chatbot content. Attackers use search ads, compromised sites, deceptive clipboard commands, and conditional delivery to evade defenses.
Key points
- Push says ClickFix accounted for 52% of its detections on average through Q2 2026 and 67% in August; four in five ClickFix pages it intercepted in 2026 came from search engines.
- Fake InstallFix pages imitate tools such as Claude Code and Codex, displaying a legitimate install command while copying a different, malicious command to the clipboard.
- Push describes LLMshare lures hosted in shared AI chats and custom GPTs; one observed custom GPT directed users to a Windows ClickFix payload hosted on sites[.]google[.]com.
- Microsoft reported that ClickFix attacks grew roughly 23-fold between December 2025 and May 2026, with Defender observing attacker-supplied commands executed on more than 1.1 million devices between February and early May.
- The article says attackers use compromised sites, search ads, conditional cloaking, in-memory execution, and EtherHiding to complicate blocking and investigation.
- Push links a ConsentFix campaign it uncovered in December 2025 to Russian state-affiliated group APT29; the lure was served only to visitors matching targeting conditions.
Article Details
- Attack Vectors
- Search ads and search-engine results lead users through redirects to compromised websites and fake AI-tool installation pages.
- InstallFix pages display a legitimate install command but copy a different command that decodes a hidden URL and pipes a downloaded script into the shell.
- LLMshare lures use shared AI chats, Artifacts, or custom GPTs to deliver malicious installation instructions or links to fake download pages.
- ClickFix pages prompt users to paste attacker-supplied commands; reported variants run in memory and use obfuscation to evade string matching.
- The reported ConsentFix campaign served its lure only to visitors whose email addresses were on a target list, and prevented repeat delivery to IP addresses that had already received it.
- Defensive Notes
- Do not rely solely on email security or URL reputation checks: many lures arrive through search engines, and some are hosted on legitimate services or compromised sites.
- Treat commands copied from web pages as untrusted, even when the page displays a legitimate command or the terminal shows a legitimate vendor URL.
- Endpoint defenses may have limited visibility when commands run in a legitimate shell, execute in memory, or are obfuscated; the article notes that some BYOD, contractor, Mac, and developer devices may lack or have reduced EDR coverage.
- Investigations may not reproduce the lure because delivery can depend on referrer, visitor email, or IP address, and pages may be rotated or taken down.
