forumtroll_apt

Also known asforumtroll_apt

ForumTroll APT is a threat group tracked by Kaspersky and attributed to Operation ForumTroll, a cyber-espionage campaign discovered in 2025. According to the provided content, the group targeted government bodies, research centers, universities, and media organizations in Russia and Belarus. The campaign began in March 2025 and used highly personalized phishing emails disguised as invitations to the 'Primakov Readings' forum. The intrusion chain exploited the Google Chrome zero-day CVE-2025-2783 to bypass Chrome's sandbox and obtain full system control. The attackers used a validator on the malicious site to confirm real users before executing the attack, achieved persistence through Windows COM hijacking, and deployed the LeetAgent spyware to steal files, execute commands, and record keystrokes. Kaspersky identified operational and code links between LeetAgent and the Dante spyware platform. Dante is described in the content as a commercial surveillance tool developed by Memento Labs, formerly Hacking Team, and the content states that ForumTroll APT has used Dante since at least 2022. Known alias in the provided content: forumtroll_apt.
