72,000 CVEs are projected to be published in 2026, while the median time from vulnerability disclosure to in-the-wild weaponization has fallen to well under 24 hours. Those two figures capture a growing challenge for defenders: more vulnerabilities to manage and less time to respond. Marc and Corey…
Cyberattacks do not always begin with malware. Sometimes they start with a job application. Sometimes with a trusted account. And increasingly, they may involve an AI agent operating with access that was originally intended for something much more routine. In Episode 389 of The 443: Security…
Artificial intelligence is no longer just helping cybersecurity teams analyze alerts, write code, or investigate threats. Increasingly capable AI models can now reason through cybersecurity problems, identify vulnerabilities, chain weaknesses together, and autonomously pursue an objective. That…
TL;DR: OpenAI models under evaluation reportedly escaped a restricted lab environment, exploited a zero-day vulnerability to gain internet access, and targeted Hugging Face while attempting to solve a cybersecurity benchmark. The incident highlights the growing risk of autonomous AI-driven attacks…
Cybersecurity technology continues to improve, but one of the biggest security challenges facing organizations remains surprisingly familiar: human behavior. WatchGuard’s 2026 Cyber Hygiene Report, based on responses from employees at small and midsized businesses across the United States, Europe…
In Episode 378 of The 443 Security Simplified, Marc Laliberte and Corey Nachreiner examine lessons from a recent CISA security incident, a vulnerability affecting the Amazon Q Developer extension for Visual Studio Code, and Microsoft research into a destructive malware platform known as Giga Wiper…
What happens when AI makes Waterfall agile? A few weeks ago, I was sitting with one of our engineering VPs while he walked me through his workflow in Cursor. Before writing a single line of code, he spent a meaningful amount of time using Cursor to craft a feature specification, a detailed natural…
Vulnerability management has never been just about finding flaws. It is about understanding which flaws matter most, which ones attackers are likely to exploit, and which ones security teams need to prioritize before they become a real business risk. That is why CVEs, CVSS scores, and vulnerability…
TL;DR: Iran-linked MuddyWater, also known as Seedworm, is using trusted software, DLL side-loading, and legitimate tools to quietly spy on high-value organizations across manufacturing, aviation, finance, education, government, and public sector environments. This campaign is not focused on…
The WatchGuard Attestation Team has uncovered an undocumented pivot framework written in Golang that opens a Smux-multiplexed SOCKS5-style pivot channel on each compromised host using one of two interchangeable transports: KCP-over-UDP with DTLS obfuscation or Noise-over-TCP with TLS obfuscation…
