How to Gain Control of AI Agents and Non-Human Identities

How to Gain Control of AI Agents and Non-Human Identities

Sep 22, 2025 AI Security / Cloud Security
We hear this a lot: "We've got hundreds of service accounts and AI agents running in the background. We didn't create most of them. We don't know who owns them. How are we supposed to secure them?" Every enterprise today runs on more than users. Behind the scenes, thousands of non-human identities, from service accounts to API tokens to AI agents, access systems, move data, and execute tasks around the clock. They're not new. But they're multiplying fast. And most weren't built with security in mind. Traditional identity tools assume intent, context, and ownership. Non-human identities have none of those. They don't log in and out. They don't get offboarded. And with the rise of autonomous agents, they're beginning to make their own decisions, often with broad permissions and little oversight. It's already creating new blind spots. But we're only at the beginning. In this post, we'll look at how non-human identity risk is evolving, where most organizations are still exposed, and...

The problem stems from a combination of two components: the use of service-to-service (S2S) actor tokens issued by the Access Control Service (ACS) and a fatal flaw in th...
Phoenix RowHammer Attack Bypasses Advanced DDR5 Memory Protections in 109 Seconds

Phoenix RowHammer Attack Bypasses Advanced DDR5 Memory Protections in 109 Seconds

Sep 16, 2025 Hardware Security / Vulnerability
A team of academics from ETH Zürich and Google has discovered a new variant of a RowHammer attack targeting Double Data Rate 5 (DDR5) memory chips from South Korean semiconductor vendor SK Hynix. The RowHammer attack variant, codenamed Phoenix ( CVE-2025-6202 , CVSS score: 7.1), is capable of bypassing sophisticated protection mechanisms put in place to resist the attack. "We have proven that reliably triggering RowHammer bit flips on DDR5 devices from SK Hynix is possible on a larger scale," the Computer Security Group (COMSEC) at ETH Zürich said. "We also proved that on-die ECC does not stop RowHammer, and RowHammer end-to-end attacks are still possible with DDR5." RowHammer refers to a hardware vulnerability where repeated access of a row of memory in a DRAM chip can trigger bit flips in adjacent rows, resulting in data corruption. This can be subsequently weaponized by bad actors to gain unauthorized access to data, escalate privileges, or even cause a...
