Rattler:Identifying and Exploiting DLL Preloading Vulnerabilities

Rattler is an automated tool for discovering and attempting to exploit DLL preloading (DLL search order) vulnerabilities in Windows applications. The post describes Rattler's methodology—identifying DLLs loaded without fully qualified paths, placing malicious DLLs in target directories, and executing the application to confirm exploitation—and discusses impacts (persistence, privilege escalation, and possible RCE), remediation (use fully qualified paths), and potential enhancements to the tool.
