SynkLoader malware spread via Microsoft Teams phishing for cred theft
- Engineer — Learn: No exploitable software vulnerability here — the attack surface is social engineering over Teams external messages. Review whether your Teams tenant restricts external/guest messaging and confirm phishing-resistant MFA is enforced for all accounts.
- SOC/IR — Plan: Active campaign using Teams external messages to deliver a fake lock screen overlay for credential harvesting; build or tune detections for Teams-sourced phishing followed by unusual lock screen events and credential access patterns in EDR telemetry.
- Leader — Learn: Confirms Microsoft Teams is an active credential-phishing vector, useful context for awareness training priorities, but no corroborating signals or sector-specific targeting reported that would require immediate leadership action.
