NIKKE's developers confirm the PC launcher's script files may have been tampered with by a third party and pushed a fix; community analysis says the code could drop a remote-access agent

If you or your users ran the NIKKE PC launcher since late September: the community write-up suggests searching Launcher/intl_service/debug.log for k2f_chan and the launcher's Local Storage for k2f.agent.state (unverified by the vendor).
On a hit, treat the machine as compromised: reimage, then rotate browser-saved passwords, session cookies, SSH and API keys from a clean device, and move any crypto wallets.
Watch for the vendor's follow-up notice on scope and remediation.
