NIKKE PC Launcher Compromised: What to Do

NIKKE PC Launcher Compromised by Third-Party Stealer Agent

Players who use the Goddess of Victory: NIKKE PC launcher published by Level Infinite may have been exposed to a stealer agent after a third party tampered with the client. The compromise was flagged in a MotherSphere GitHub report and amplified across Reddit, with Shift Up and Level Infinite confirming that fixes are available and investigations are underway. For ongoing coverage, see our latest goddess-of-victory-nikke updates.

What Happened and When

The MotherSphere report states the vulnerability appeared on 2026-09-27 and may have been present and in use since 2026-10-23. During that window, opening the PC launcher could have downloaded a stealer agent onto a player's system.

A stealer agent targets stored credentials and sensitive data. According to the report, affected programs could include browsers, Discord, and Steam, putting passwords, payment information, and crypto wallets at risk.

How to Check If You Were Affected

The report outlines a direct check: open the debug.log file inside the Launcher/intl_service folder. If the k2f_chan agent was registered and started, that indicates the stealer component ran.

• Navigate to the Launcher/intl_service directory.
• Open debug.log.
• Look for k2f_chan registration and startup entries.

What to Do If You Opened the Launcher

If you launched the PC client during the affected period, the report advises changing passwords and running virus scans. Prioritize accounts tied to payment methods and any crypto wallets.

Players who did not open the launcher since the incident are advised to delete the tbs_cache folder and leave it untouched until an all-clear is issued.

Official Response

Shift Up's official social media account and Level Infinite stated that fixes are available and that investigations are ongoing, with more updates planned. Neither company has published a full technical timeline in the supplied materials. Specific patch numbers and server times for the fix are not stated in official materials.

Community Reaction

On Reddit, posts by SeValentine and Shoddy_Rhubarb_842 helped surface the issue, while the MotherSphere GitHub write-up provided the technical verification steps. The conversation has centered less on gameplay and more on account security, with players comparing notes on debug.log findings and urging caution before reopening the client.

What It Means

The incident is a reminder that launcher-level compromises sit outside normal gacha planning. Until an official all-clear is issued, treat the PC client with caution, verify your debug.log, and rotate credentials for any account that may have been exposed. Goddess of Victory: NIKKE remains available on PC and mobile.
