What it detects

This rule detects the renamed Windows debugger cdb.exe masquerading as fontdrvhost.exe in C:\ProgramData and loading shellcode from config.ini, a loader used by the Squidoor backdoor. Running the signed cdb LOLBin under a spoofed name from a non-standard path proxies malicious code execution past application controls.
