Investigating an adversary-in-the-middle phishing campaign targeting Microsoft 365 and Okta users
Datadog details an adversary-in-the-middle phishing campaign stealing M365 and Okta session tokens — a direct threat to enterprises relying on federated identity without phishing-resistant MFA.
Summary written by editorial AI · Source link below
In this post, we investigate a recent phishing campaign that targets Microsoft 365 users.
Editorial Analysis
AitM attacks bypass traditional MFA by proxying authentication in real time; organisations still relying on SMS or TOTP-based MFA face elevated session-hijacking risk.
Enforce phishing-resistant MFA (FIDO2/WebAuthn) for M365 and Okta, and deploy conditional-access policies that evaluate token-binding and device compliance.
Session-hijacking phishing campaigns can bypass standard MFA — upgrading to hardware-based authentication significantly reduces this board-level identity risk.
