From ClickFix to FileFix: A New Era of Deception from the Interlock Ransomware Group

The Interlock ransomware group has evolved its cyberattack tactics by introducing a powerful PHP-based Remote Access Trojan (RAT). This new version, dubbed FileFix, uses fake CAPTCHA prompts to trick users into executing malicious PowerShell scripts. Once inside, the malware performs deep reconnaissance, steals sensitive data, and maintains persistence through advanced hiding techniques using Cloudflare Tunnels. Experts warn that this marks a dangerous shift in ransomware behavior.📌 Key Highlights:Shift from Node.js to PHP-based RATFake CAPTCHA via FileFix trickDeep system reconnaissance and privilege checkingCommunication hidden via Cloudflare TunnelPersistence using registry keys and backup IPs#InterlockRansomware #FileFix #CyberAttack #MalwareAlert #CyberPlatter
