The $339 Trillion Glitch: Ubisoft Loses Control of Rainbow Six Siege in Massive Breach

The Daily CyberSecurity report dated 30 December 2025 describes a hacker attack that compromised Ubisoft’s Rainbow Six Siege servers, with attackers infiltrating the system and granting large amounts of in‑game currency and items to many players. This triggered the BattlEye anti‑cheat system to interpret the activity as illicit, resulting in a substantial number of account bans, including some well‑known players.

Ubisoft’s human moderation teams identified the root of the issue and began taking the servers offline for maintenance and security checks, gradually lifting bans on affected accounts; any abnormal currency and items added during the incident are being removed.

In an official statement, Ubisoft said the issue would be resolved through data rollbacks and comprehensive quality control testing to ensure account integrity and the validity of all changes, though they cautioned that a specific restoration timeline could not be guaranteed. Rainbow Six Siege remains under unplanned maintenance across all platforms, leaving players waiting for the rollback process to complete. The article notes that no information has yet emerged about the perpetrators or any monetary motive.
