Metascan Confirms Limited Data Breach After Two-Minute Telegram Bot Compromise
Metascan has publicly acknowledged a data breach involving internal materials obtained through a compromised Telegram bot token. The attacker gained access to a corporate Telegram chat for approximately two minutes on September 5 and exported a small set of documents before being removed. The incident stemmed from an overlooked bot token on test virtual machines after an employee departure. Among the leaked items were two pilot project reports from July 2026 that mentioned major Russian organizations including Transneft, Selectel, Lenta, Sberbank, and Rostelecom. Metascan attributed the leak to a former employee now working with a competitor and rejected claims of deliberately hidden vulnerabilities. The company has accepted full responsibility, outlined corrective measures, and launched a bug bounty program.
