Within 90 seconds of compromise, a threat actor triggered multiple post-access sequences. Our threat researchers believe this activity was AI-enabled.

🤝 No single vendor can secure the agentic enterprise alone.
That's why we're launching the @the_blueprintai — cross-industry coalition with @AWS , @CrowdStrike , @databricks , @Docker , @GEAppliancesCo , @googlecloud , @Lovable , @proofpoint , @salesforce , @ServiceNow , @wiz_io , @WCKitchen , and @zscaler .
Together, we're building an open reference architecture to answer 4 critical questions:
Where are my agents? What can they do? What are they doing? How do I respond?

Russian state-backed hackers have spent the past year targeting employees in the US and NATO countries using an email exploit that steals comms just by having a target open a message, no clicks required.

🚨 We are following up with additional observations of the TA488’s use of “half-click” exploits.
The group has initiated a new wave of exploitation abusing a cross-site scripting (XSS) vulnerability, CVE-2026-42897, in Outlook Web Access (OWA).

Researchers at @Proofpoint are tracking Cruciferra, a crypter service that is used by multiple unrelated threat actors.
The self-proclaimed “underground's most lethal crypter” has been observed delivering a wide range of RATs and infostealers.

Proofpoint has identified OAuth client ID spoofing emerging as a stealthy account enumeration technique targeting Microsoft Entra ID.
Attackers can validate usernames and infer credential validity, all without generating a successful sign-in event. proofpoint.com/us/blog/threa…
