Is Shai-Hulud Back? Compromised Bitwarden CLI Contains a Self-Propagating npm Worm

Version 2026.4.0 of the widely-used @bitwarden/cli npm package (78,000 weekly downloads) has been identified as malicious. The package contains a sophisticated multi-stage credential theft worm that explicitly names itself "Shai-Hulud: The Third Coming", a direct callback to previous Shai-Hulud supply chain campaigns, and targets developer credentials including SSH keys, cloud secrets, and even MCP configuration files.

Application Security Prioritization: How the Best Teams Fix What Matters Most

In the race to ship software faster, security teams are drowning. Not in vulnerabilities… those are abundant, predictable even. They’re drowning in noise. The average enterprise application generates thousands of security findings from multiple scanners, each screaming for attention with equal urgency. Meanwhile, developers are building faster than ever, fueled by cloud-native architectures, open-source dependencies, and AI-generated code. The uncomfortable truth?

From Panic to Playbook: Modernizing ZeroDay Response in AppSec

Why the next Log4Shell will be won or lost in the first 72 hours—and what a modern zero‑day workflow looks like. Every security team remembers where they were when Log4Shell dropped. A quiet Friday afternoon in December 2021 turned into a weekend of war rooms, emergency patches, and executive updates. Years on, the Log4j fallout still shows up in breach reports—a stubborn reminder that zero‑days don’t end when the news cycle does.

Multiple Cross-Site Scripting (XSS) Vulnerabilities in Mailcow

Mailcow is a widely used self-hosted and open source email server that hosts everything you'd need to manage mailboxes yourself. To assess its security, we set up a local instance and ran our AI pentesting agents against it. We found three XSS vulnerabilities, including a critical vulnerability that allowed unauthenticated attackers to take over administrator accounts while looking at their logs in the UI. Gaining access to a mailbox can have a serious security impact.

Axios CVE-2026-40175: a critical bug that's... not exploitable

It’s been a chaotic few weeks for Axios. First, a major supply chain attack put the package under scrutiny. Then, just days later, headlines started appearing about a “critical 10/10 vulnerability” that could lead to full cloud compromise. If you’ve read the coverage, you’ve probably seen claims like: That sounds bad. But when you look closely at how this vulnerability actually behaves in real environments, the story changes.

Why Securing AI Code Generation is Critical for AppSec

The revolution is here, but it’s not what we expected. AI coding assistants have transformed software development, with developers shipping code faster than ever before. GitHub Copilot, Amazon CodeWhisperer, and Claude Code have become as essential to modern development as Git itself. The productivity gains are undeniable; what once took hours now takes minutes. But there’s a dangerous blind spot in this revolution: security.
