Goddess of Victory: NIKKE will receive an additional PC launcher security update on November 12, 2026, following a malware distribution incident that potentially exposed players’ Windows computers and account information. Publisher Level Infinite confirmed the upcoming update in a November 10 security announcement, alongside improvements to the launcher’s built-in malware detection and removal feature.
The November 12 update is intended to strengthen file integrity and source authenticity checks throughout the launcher’s resource transmission, downloading, and execution processes. These additional protections are designed to reduce the risk of malicious or modified resources being delivered through the official launcher.
The announcement follows the NIKKE PC launcher malware attack, which involved attackers modifying files used by the game’s legitimate Windows launcher. The compromised resources could execute malicious software on players’ computers without requiring them to download an unofficial version of the game.
Level Infinite previously confirmed that an external domain used by certain game services was hijacked on September 27. Launcher scripts were subsequently modified, with malicious software distribution beginning on October 30. The company detected abnormalities on November 4 and deployed fixes, including replacing compromised scripts and refreshing affected content delivery network caches.
According to the publisher, corrective measures completed on November 4 stopped further malware distribution through the compromised launcher, allowing normal PC launcher services to resume. However, those fixes do not automatically eliminate malicious software that may have already reached players’ computers.
The company has therefore reiterated its recommendation that anyone who launched the Windows PC client after September 27 at 15:41 (UTC+9) perform a security check. Although malware distribution began later, the broader precautionary period reflects when launcher resources were first compromised.
The official PC launcher now includes an automated security feature designed to identify and remove malicious components associated with the incident. Level Infinite confirmed on November 10 that the security-check interface supports multiple languages, with notifications displayed according to the user’s system language.
Players should close all web browsers, including Google Chrome, before starting the launcher security check. The process generally takes approximately 30 seconds to two minutes. If affected components are detected, a notification will appear requesting permission to remove associated files, logs, and registry entries.
If no detection notification appears, the launcher can proceed normally. However, players should not interpret this as a guarantee that their entire computer is free from unrelated malware or other security threats.
For players who have uninstalled NIKKE or prefer not to run its launcher, Level Infinite has published official manual security-check instructions. These explain how to inspect launcher logs for evidence of possible malicious execution and identify affected system components.
One indicator identified in the official instructions is the string “k2f_chan registered” within the launcher’s debug.log file. Its presence suggests that malicious software may have executed, although the absence of the string does not conclusively rule out compromise.
The publisher also recommends performing a full antivirus scan and a Microsoft Defender Offline scan. Players following the manual removal instructions should carefully verify file paths and registry entries before deleting anything, as removing unrelated system components could cause additional problems.
Account security remains another concern. Level Infinite advises potentially affected players to change passwords for accounts accessed on the compromised computer. Anyone who stored or used API keys or access tokens on the device should revoke those credentials and generate replacements.
These account protection steps should be performed from a separate, trusted device or after completing the security checks on the affected computer. Players who suspect account compromise, unauthorized activity, or financial losses are encouraged to contact the publisher’s customer support service.
Level Infinite has also cautioned players against relying on unofficial recovery tools. The publisher recommends using its official security-check procedures rather than downloading unverified software claiming to repair the launcher incident.
The security breach was limited to the Windows PC launcher. According to the company’s earlier clarification, players who exclusively used the Android or iOS versions of Goddess of Victory: NIKKE were not affected by this particular incident and do not need to perform the related PC security checks.
The November 12 update represents a further security measure rather than the initial fix for the compromised launcher. Level Infinite says it will continue monitoring the launcher’s security and implementing additional protections where necessary, while its investigation into the potential impact on affected players continues.
