A program to share information with cybersecurity companies may have exposed unpatched flaws in the company's SharePoint service.

Both Microsoft and Trend Micro later said that hackers had actually begun exploiting the bugs on July 7, a day before the patches. It is unclear how these hackers learned of these flaws, Childs said. Trend Micro said a technology company—which it declined to identify—was compromised in the attack that it observed.

The vulnerability opening the way for the attack was first identified in May at a Berlin hacking competition organised by cybersecurity firm Trend Micro that offered cash bounties for finding computer bugs in popular software.

Both techniques remain popular with state-sponsored and cybercriminal groups, says Peter Girnus, a senior threat researcher with cybersecurity firm Trend Micro's Zero Day Initiative (ZDI).

Louise McEvoy, Trend Micro’s vice president of U.S. channel, told CRN in an email that the vendor is “working to ensure that the changes within Microsoft’s MVI program strengthen our joint business.”

This new feature also has a security hole that "could affect thousands of AI agents," according to Trend Micro principal threat researcher Sean Park, who detailed the flaw and how an attacker could exploit it to hijack a support bot in a Tuesday post.

Operation Secure was also assisted by private cybersecurity partners, including Kaspersky, Group-IB, and Trend Micro.

Hallucination mitigation is also a core part of Trend Micro's responsible AI development strategy, says Shannon Murphy, senior manager of global security and risk strategy at Trend Micro. The company recently open sourced its threat detection AI model and agent, Trend Cybertron.

Irrespective of market conditions, only the top 5% of the Zacks-covered stocks get a 'Strong Buy' rating and the next 15% get a 'Buy' rating.

Kevin Simzer, chief operating officer at Trend Micro, shared a firsthand experience with me that emphasizes this shift. At a CISO roundtable just nine months ago, he polled the room—and every single participant was trying to block AI tools. Now? “We’re about to release some new research... and actually, 97% of them are leveraging AI,” Simzer said.
