Just 474 of the 1,000 most popular websites set DMARC to reject spoofed mail, a dev.to survey of their DNS found. Thirty-two months after Google and Yahoo began requiring DMARC from bulk senders, 84.5% of the sites publish a record, but only 69.4% apply an enforcing policy to all their mail.

Microsoft's record September release fixed up to 997 CVEs, including two local escalations to SYSTEM that attackers used before the patch shipped. A 7.8 score understates the step that turns a phishing foothold into control of the machine, so both go ahead of the 9.8 remote flaws.

Recorded Future says filtering, verification and training still blunt most AI phishing, with deepfaked voice and video the exception. Its advice is to stop treating a familiar face or voice on a call as proof of identity.

Proofpoint says an unknown actor sprayed over 5,700 M365 accounts in Chile and breached only seven, all dormant service accounts at one retailer. Employee logins held, and those seven unused accounts still gave the attacker mail, Teams chats, OneDrive files and, in one case, the Azure portal.

Have I Been Squatted found Corp MDM, a small Android implant that takes newly arriving SMS and switches on call forwarding, sharing one hard-coded address with the credential phishing and Windows malware aimed at the same sector.

Rapid7's research with Zimbra turned up more than 50 vulnerabilities, several of which let an attacker send mail as another user with no password involved. The operational item today is CVE-2026-73570, the SNMP command injection CISA gave federal agencies three days to fix.

Proofpoint tracked three waves of TeamFiltration password spraying against Microsoft 365 tenants in Chile between July 21 and August 16. The seven accounts that opened were all functional identities carrying provisioned passwords with no MFA.
