ClickFix Campaign Exploits Placeholder Domain and Ukrainian SitesThreat
The 'third-party[.]com' domain, long used as a documentation placeholder, is now serving malicious ClickFix lures to Windows users. This technique, also observed compromising legitimate Ukrainian business websites with fake Cloudflare pages, tricks victims into downloading the new Psychedelic information stealer.
Why it matters: Be cautious of unexpected security prompts, even on trusted websites. Attackers are using sophisticated social engineering to deliver malware, so always verify requests directly from known sources.
