Engineer — Plan: Audit endpoints for unauthorized ScreenConnect installations and enforce application control policies that block unsanctioned RMM tools; no software vulnerability to patch, but tightening allow-lists prevents this class of persistence.
SOC/IR — Act: Active campaign — hunt for ScreenConnect processes spawned by fake update installers or document-review lures; tune EDR/SIEM rules to flag unsanctioned RMM tool execution, mapping to ATT&CK T1219 and T1566.
Leader — Learn: A recurring pattern of RMM-as-backdoor via lure campaigns; reinforces the need for ongoing phishing simulation and user awareness around unsolicited software update prompts, but no immediate leadership action required.

Engineer — Learn: No patch or config action — this is a social-engineering delivery chain, not a software vulnerability. Worth knowing that legitimate RMM binaries (Level RMM, ScreenConnect) are being weaponized so anomalous installations can be flagged during code-review or build-pipeline audits.
SOC/IR — Act: Active campaign uses a fake Microsoft Teams update lure to drop legitimate RMM tools that provide persistent remote access; hunt for unexpected Level RMM or ScreenConnect processes spawned from browser or user-space paths, and tune detections for counterfeit Microsoft Store redirect chains since Teams-themed lures are a high-volume enterprise vector.
Leader — Learn: Noteworthy campaign pattern — abusing legitimate RMM software bypasses many controls — but no named vendor breach or regulatory trigger; file for context when briefing on social-engineering trends or evaluating security-awareness training priorities.
