Microsoft confirms Outlook security flaw exploited by cybercriminals, unlinked to global outage
Microsoft confirmed a spoofing vulnerability in Outlook, identified as CVE-2026-124194, that was being actively exploited by cybercriminals. An unauthenticated attacker can send a specially crafted file that, once opened, lets Outlook connect to an attacker-controlled network location and expose the user's NTLMv2 hash. The company released a security update on November 10. The flaw coincided with an outage of more than 12 hours affecting Microsoft 365 services, which the company attributed to process overload on some servers and did not link to the attack.

They note that models can generate almost any content while the product decides what to filter, and that filtering has a cost.
