TellYouThePass is actively exploiting CVE-2024-4577, a PHP CGI argument-injection RCE, to execute arbitrary code and deploy living-off-the-land ransomware via HTA files, mshta.exe, and .NET payloads; a public PoC exists and PHP patches (8.1.29, 8.2.20, 8.3.8) and mitigations (disable CGI, use WAF/AV, patching) are recommended.
