Anthropic's AI Model Exposes Code Flaws, But Limitations Remain
Meet Mythos, a game-changing AI tool that automates code auditing with impressive accuracy, but isn't quite a magic bullet for uncovering entirely new software flaws. It's highly effective at spotting known vulnerabilities, but its capabilities are still limited to what humans have taught it.
Cal.com Shifts Away From Open Source Amid AI-Driven Security Concerns
Cal.com is ditching open source, citing AI-driven security risks that make transparent code a liability. Its CEO claims open source is dead, as AI tools empower attackers to exploit published code like never before.
CISA Flags Four Exploited Vulnerabilities, Sets Federal Patch Deadline
The US Cybersecurity and Infrastructure Security Agency (CISA) has flagged four actively exploited vulnerabilities, urging Federal Civilian Executive Branch (FCEB) agencies to patch or discontinue use of affected systems by May 8, 2026. These critical flaws, detailed in CISA's Known Exploited Vulnerabilities (KEV) catalog, pose a significant threat to cybersecurity and must be addressed promptly.
TekStream Bolsters Proactive Security with ImagineX Cyber Acquisition
TekStream is taking a proactive approach to security with its acquisition of ImagineX's cyber business, expanding its services to help prevent incidents and align security strategies with business goals. This strategic move bolsters TekStream's offerings with advisory, GRC, and vulnerability management capabilities.
Linux Kernel Faces Large-Scale Device Support Cuts
The Linux kernel is set for a major overhaul, with plans to cut support for dozens of outdated devices, including ancient network cards and legacy parallel-port hardware, freeing up thousands of lines of code and reducing the maintenance burden. This could slash nearly 30,000 lines of code, just from Ethernet device removals alone.
Frontier AI Exposes Gaps in Traditional Security Programs
Imagine having the power to replicate a full year’s worth of manual penetration testing in just three weeks - that's the reality with frontier AI, which has exposed significant gaps in traditional security programs. Palo Alto Networks and Unit 42 have revealed that advanced models like Anthropic Mythos can autonomously identify software vulnerabilities and adapt to defensive controls in near-real-time.
Flaws in Hybrid Cloud Tools Expose Dual Attack Surfaces
Researchers have uncovered four vulnerabilities in Microsoft's Windows Admin Center, exposing a dual attack surface in hybrid cloud tools that may be flying under your radar. If left unmonitored, this unmanaged attack surface can leave your organization vulnerable to potential threats.
AI-Powered Vulnerability Discovery Outpaces Remediation
The AI-powered Mythos model discovered a staggering number of vulnerabilities, including a 27-year-old bug in OpenBSD and a four-bug exploit chain that bypassed browser and OS defenses, with fewer than 1% of these vulnerabilities patched. This led Anthropic to delay a public release and share the findings with tech giants like Apple and Microsoft to prioritize patching.
CISA Mandates Patching of Exploited BlueHammer Flaw in Federal Systems
Don't let your federal systems become an easy target: CISA is mandating the patching of the exploited BlueHammer flaw to prevent malicious cyber actors from gaining a foothold. A high-severity vulnerability in Microsoft Defender can allow low-privileged users to gain SYSTEM permissions - but a patch is available.
