The CertVerify is a tool designed to detect executable files (exe, dll, sys) that have been signed with untrusted or leaked code signing certificates. The purpose of this tool is to identify potentially malicious files that have been signed using certificates that have been compromised, stolen, or are not from a trusted source.
Executable files signed with compromised or untrusted code signing certificates can be used to distribute malware and other malicious software. Attackers can use these files to bypass security controls and to make their malware appear legitimate to victims. This tool helps to identify these files so that they can be removed or investigated further.
As a continuous project of the previous malware scanner, i have created such a tool. This type of tool is also essential in the event of a security incident response.
