Don’t Sweat the ClickFix Techniques: Variants & Detection Evolution

This report analyzes the evolution of the ClickFix copy-and-paste initial access technique and its variants (FileFix, TerminalFix, DownloadFix), highlighting a sharp rise in use and cross-platform targeting by manipulating users to execute attacker-supplied commands via Run, File Explorer, PowerShell, or a fake download “repair” script. It details lures (e.g., fake Cloudflare interstitials, simulated failed downloads), execution chains and artifacts (e.g., explorer.exe → conhost.exe → curl.exe, browser-launched PowerShell, RunMRU/TypedPaths entries, Zone.Identifier streams), and proposes detection chokepoints centered on scripting interpreters, parent-child process relationships, and outbound network activity to identify current and future iterations.
