Daily Cyber News: Microsoft fixes exploited Outlook attack in massive patch release
Organizations face an actively exploited Outlook credential-theft path within a record-breaking Microsoft update covering one thousand two hundred thirty five flaws. A malicious message file must be opened. Outlook can then connect to an attacker-controlled location without showing its usual external-content warning and expose an NTLM authentication hash.
Key context: The size of the update creates a difficult prioritization problem for large Windows estates.
Additional detail: Patch the exploited Outlook issue first, then accelerate testing and deployment for exposed network services and high-value systems.
