Operation ForumTroll: Inside a Coordinated Espionage and Influence Campaign Targeting Eastern Europe

Operation ForumTroll is a persistent, pro-Russian-aligned hybrid espionage and influence campaign focused on Eastern Europe that uses persona-driven forum and social network infiltration, credential phishing and cloud token theft, lightweight backdoors and document collectors, and coordinated disinformation to map social graphs, collect intelligence, and manipulate narratives; activity documented from 2020–2024 shows evolving tradecraft and ephemeral cloud-based C2, and recommended defenses include MFA, token audits, stronger moderation, and user training.
