The attacker cites the genuine deadline to create urgency: \"basic authentication is being deprecated,\" \"SMTP AUTH deadline April 30,\" \"your app password will stop working,\" \"legacy SharePoint authentication IDCRL is retiring May 1.\" The email then pushes a panic CTA — \"migrate now,\" \"re-authenticate now to avoid service disruption,\" \"your mailbox will be suspended\" — pointing at a non-Microsoft URL that looks like an O365 sign-in page but harvests credentials. The real Microsoft 2022 first-wave basic-auth deprecation spawned dozens of phishing campaigns per Sophos and Microsoft's own threat reports; the April 2026 deadline is expected to replay that wave, with tens of millions of users and every IT admin in the world in-play. Distinct from generic MS365 credential phishing because it rides on a REAL policy change with a REAL deadline — users who know the deadline is real are primed to click.

Any \"migrate now to avoid mailbox suspension\" email whose link target is a non-Microsoft host is, by construction, a phish — there is no legitimate third-party migration portal.","tier":"danger","category":"other","isThin":false}}
