What is it?

NIKKE Hack Checker is an unofficial Windows utility for checking whether a PC was compromised through the November 2026 NIKKE (Goddess of Victory: Nikke) PC launcher hack and for removing leftover traces. The scan is read-only and changes nothing. Fixes run only for items the user checks, and a report is saved before anything is deleted.

The scanner looks at launcher logs and agent download records, launcher storage state, attacker server connection records, malicious DLLs in Chromium-based and Firefox browser profiles, registry COM hijacking entries, running processes with malicious modules loaded, and hosts and firewall blocking. It also covers cleanup of the launcher cache and processes, blocking of attacker domains and IPs, and optional deletion of cookies and site data. The tool does not connect to the internet and does not send results anywhere.

The project is written in Go with no external packages and is built into Korean and Japanese executables from a shared source tree.
