Ontinue: 30% of Firms Hit by Fake IT Support Teams Attacks
Zurich – October 13, 2026 -- Approximately 30% of monitored organizations experienced at least one fake IT support impersonation attempt through Microsoft Teams in the first half of 2026, according to Ontinue's 1H 2026 Threat Intelligence Report. The managed detection and response (MXDR) provider says attackers are gaining scale by exploiting trusted identities, collaboration platforms, software supply chains and routine business workflows rather than by building more sophisticated malware.
The findings draw on incident investigations, threat intelligence research and telemetry from Ontinue's Advanced Threat Operations team.
