The domain third-party[.]com, historically used as a documentation placeholder similar to example.com, has been compromised and now serves ClickFix lures to Windows users while displaying harmless content to other operating systems. Since at least June 2026, Windows visitors receive a fake Cloudflare verification page that poisons the clipboard with a malicious PowerShell command, instructing users to press Win+R and paste the payload. The domain appears in over 1,500 files across 1,700+ repositories from trusted sources including Chromium, Sanity, and Vercel. Unlike example.com, third-party[.]com is not IANA-reserved, allowing adversaries to register and weaponize it. The attack leverages social engineering to bypass security tools by using signed Windows binaries, making detection difficult through traditional scanning methods.
