Microsoft is investigating an ongoing issue causing some Windows users to face significant delays or outright failures when launching the Microsoft Teams desktop client. The company acknowledged the problem, tracked internally as TM1466820, and confirmed it remains unresolved as engineers continue digging through service logs to find a root cause. According to Microsoft’s incident notice, affected users encounter trouble specifically during the first launch of Teams on a Windows device. Some cannot load the client at all, while others experience delays stretching up to two minutes before the…

A human attacker armed with frontier artificial intelligence models breached an enterprise network and seized root credentials in under 10 hours, a timeline that would normally take human red teams roughly two weeks to complete, according to a new incident response report from Palo Alto Networks’ Unit 42. The threat actor told Unit 42 investigators during ransom negotiations that they relied on frontier AI models paired with attack-specific agentic AI frameworks to automate the intrusion. Rather than manually executing each stage of the attack, the operator directed AI agents to monitor…

A previously undocumented Linux toolkit has been found compiled directly into the trojanized HAProxy load balancers of two South Korean organizations, where it intercepted web traffic and served altered pages to selected visitors. The attackers named the implant ted in debug strings left in the binary. It is not a HAProxy vulnerability, and installing it requires code execution on the host and

The disgruntled security researcher known as Nightmare Eclipse (aka Chaotic Eclipse, Infinite Nightmare, and now also MSNightmare) is moving away from their singular Microsoft vendetta and on to other vendors. On Thursday, they dropped a new zero-day bug called FalconFlank that affects CrowdStrike’s Falcon endpoint security platform - albeit with a Windows link. According to the prolific zero-day hunter, FalconFlank is a privilege escalation vulnerability that abuses the Microsoft Office malicious macros remediation feature in CrowdStrike Falcon. This is an automated security tool built into…

Google on Wednesday announced Gemini 3.8 Flash Cyber, which it described as its most capable cybersecurity model, and has made it available to a set of trusted defenders via a new initiative called the Fairwind Program. "The Fairwind Program gives high-priority defenders (like governments, healthcare providers, and telecommunications services) early access to advanced models that help them

A financially motivated threat group known as Toy Ghouls has begun using two custom Windows backdoors that communicate through popular messaging and broker services. The tools give attackers a discreet way to run commands, collect system details, and maintain control over compromised devices. The campaign marks a change for the group, which had previously relied heavily on public tools and leaked ransomware builders. Its move to custom malware suggests a broader effort to stay inside victim networks longer while making activity harder for security teams to spot. Analysts at Securelist…

Threat actors are exploiting two critical security flaws in WordPress plugins Super Forms and Elementor Pro, according to findings from Wordfence. The vulnerabilities in question are - CVE-2026-14894 (CVSS score: 9.8) - A missing file type validation vulnerability in Super Forms – Drag & Drop Form Builder that allows unauthenticated attackers to upload files of any type, including

Cisco has warned its customers of three critical-rated flaws in its products. Two of them are present in the Cisco IOS XR operating system that powers the company’s carrier-grade kit. CVE-2026-20274 scores 9.8 on the ten-point CVSS scale and covers a buffet of buffering issues, the potential for out-of-bounds writes, and the chance to initialize resources with an insecure default. CVE-2026-20279 is another 9.8-rated flaw. Cisco says it’s an improper access control problem that covers “improper certificate validation, missing authentication for critical function, missing authorization, and…

First, the good news: If you use a Linux-based operating system, you may not be asked your age in a few months. The bad news is that Windows, macOS, iOS, and Android users in California will be. California has passed a law that requires a range of operating systems to start collecting your age when you first set them up. Under the state’s Digital Age Assurance Act (DAAA), signed into law in October 2025, Windows, macOS, iOS, and Android will all have to do this from January 1, 2027. Operating systems set up before that date in California will need to do the same by July 1, 2027. Operating…
