What it detects

This rule detects regedit.exe silently importing an InboxCorePro registry file, a step the Nimbus RAT uses to apply its configuration and persistence keys. The reg file is dropped alongside the Java payload in the ProgramData install directory. Automated registry imports referencing the malware family name indicate implant setup.
