NATO Admiralty (AJP-2.1) grades confidence, independent of the risk score. Cross-source corroboration isn't tracked for non-CVE news, so single-source items are capped at a lower credibility number; a low number does not imply low quality.
Key insight
Attackers exploit passkey-themed phishing lures to trick users into revealing Microsoft 365 authentication credentials,a tactic that exploits modern security expectations.
Description
Passkey-themed phishing campaigns target Microsoft 365 users using social engineering techniques that play on the adoption of passwordless authentication. Attackers send convincing phishing emails that prompt users to enter their authentication credentials by claiming a passkey setup or authentication verification is required. Upon successful compromise, attackers gain access to Microsoft 365 accounts including email, Teams, SharePoint, and OneDrive, leading to data exfiltration and lateral movement. This campaign is actively exploited in the wild and leverages heightened awareness of passkeys as an attack vector.
