TellYouThePass is a ransomware family active since at least 2019. It encrypts files on compromised systems and issues ransom demands for decryption. Observed campaigns have exploited public-facing remote-code-execution vulnerabilities, including CVE-2024-4577 in PHP CGI on Windows, CVE-2023-46604 in Apache ActiveMQ, and Apache Log4j vulnerabilities. In exploitation of CVE-2024-4577, operators used the vulnerability to deploy webshells, invoke mshta.exe to execute an HTA/VBScript stage, and load a .NET ransomware payload into memory. The documented PHP campaign affected vulnerable Windows PHP CGI deployments, including exposed default-style XAMPP configurations, and demanded cryptocurrency payment. TellYouThePass has also been observed as a payload delivered through exploit chains targeting server infrastructure.

3 CVEs Mallory has correlated with this family across public research and vendor advisories. Each row links to the full Mallory page for that vulnerability.
A critical remote code execution vulnerability in PHP CGI affects Windows versions of PHP CGI and allows unauthenticated attackers to execute arbitrary code remotely through argument injection. TellYouThePass began exploiting it after patches were released. | The TellYouThePass ransomware gang has been exploiting the recently patched vulnerability (CVE-2024-4577) in PHP to deploy webshells and execute their encryptor payload on target systems.
This ransomware group is not sophisticated, but they have a track record of rapidly adopting public exploits for new vulnerabilities to enable victim compromise; past examples include CVE-2021-44228 (Log4j) and CVE-2023-46604. | According to the company Imperva, the TellYouThePass ransomware group is exploiting CVE-2024-4577 to execute PHP code on the victim system and to run an HTML application file. The file contained a VBScript, which in turn resulted in the deployment of a .NET variant of TellYouThePass ransomware.
