Microsoft Warns of TerminalFix Attacks Deploying Reverse Tunnels
A new ClickFix variant named TerminalFix uses fake Cloudflare CAPTCHA prompts to trick Windows users into executing malicious PowerShell commands.
Microsoft security researchers have issued a warning regarding a newly uncovered cyberattack campaign dubbed TerminalFix. This threat represents a sophisticated evolution of the ClickFix tactics, leveraging compromised websites to target unsuspecting users.
During the attack, visitors to hacked or spoofed websites are presented with convincing fake Cloudflare CAPTCHA prompts. Victims are tricked into believing they need to complete a verification step, which actually involves copying and executing malicious PowerShell commands.
Once these commands are run inside the Windows Terminal, the attackers establish reverse tunnels. This mechanism grants unauthorized remote access to the compromised system, allowing threat actors to further infiltrate the network and deploy additional payloads.
This campaign highlights the growing reliance on social engineering techniques that bypass traditional security controls by manipulating the user into performing the dangerous actions themselves.
For technology users and system administrators, this serves as a crucial reminder to exercise caution online. Never execute raw commands or scripts provided by unverified web prompts in your terminal or command-line interface under any circumstances.
