After Mythos: New Playbooks For a Zero-Window Era

Apr 28, 2026 Artificial Intelligence / Enterprise Security
When patching isn’t fast enough, NDR helps contain the next era of threats. If you’ve been tracking advancements in AI, you know the exploit window, the short buffer that organizations relied on to patch and protect after a vulnerability disclosure, is closing fast. Anthropic’s new model, Claude Mythos , and its Project Glasswing , showed that finding exploitable vulnerabilities and subtle cracks in your defenses in operating systems and browsers — work that once took experts weeks — can now be done in minutes with AI. As a result, the patch window of opportunity is now near-zero . The situation is so critical that Treasury Secretary Scott Bessent and Federal Reserve Chair Jerome Powell recently convened an urgent meeting with the CEOs of major U.S. financial institutions to discuss the implied risks. The takeaway was straightforward: surging AI capabilities have upended risk profiles, with profound implications for institutional stability and integrity across industries.  ...

Microsoft Patches Entra ID Role Flaw That Enabled Service Principal Takeover

Microsoft Patches Entra ID Role Flaw That Enabled Service Principal Takeover

Apr 28, 2026 Vulnerability / Identity Management
An administrative role meant for artificial intelligence (AI) agents within Microsoft Entra ID could enable privilege escalation and identity takeover attacks, according to new findings from Silverfort . Agent ID Administrator is a privileged built-in role introduced by Microsoft as part of its agent identity platform to handle all aspects of an AI agent's identity lifecycle operations in a tenant. The platform enables AI agents to authenticate securely and access necessary resources, as well as discover other agents. However, the shortcoming discovered by the identity security platform meant that users assigned the Agent ID Administrator role could take over arbitrary service principals , including those beyond agent-related identities, by becoming an owner and then add their own credentials to authenticate as that principal. "That's full service principal takeover," security researcher Noa Ariel said . "In tenants where high-privileged service principals...

Apr 23, 2026 Hacking News / Cybersecurity News
You scroll past one incident and see another that feels familiar, like it should have been fixed years ago, but it still works with small changes. Same bugs. Same mistakes. The supply chain is messy. Packages you did not check are stealing data, adding backdoors, and spreading. Attacking the systems behind apps is easier than breaking the apps themselves. The exploits are simple but still work, giving attackers easy access. AI tools are also part of the problem now. They trust bad input and take real actions, which makes the damage bigger. Then there are quieter issues. Apps take data they should not. Devices behave in strange ways. Attackers keep testing what they can get away with. No noise. Just ongoing damage. Here is the list for this week’s ThreatsDay Bulletin.
