In March 2025, Kaspersky identified a sophisticated cyber espionage campaign dubbed Operation ForumTroll, targeting Russian and Belarusian organizations via spear phishing emails with personalized links. The attack exploited a zero-day vulnerability in Google Chrome (CVE-2025-2783) to escape the browser sandbox, leveraging a logical flaw in Windows IPC handling of pseudo-handles. The threat actor used LeetAgent, a custom spyware, and was linked to the commercial Dante spyware developed by Memento Labs (formerly Hacking Team), indicating a well-resourced and persistent threat actor conducting long-term surveillance operations.
