From Panic to Playbook: Modernizing ZeroDay Response in AppSec

Apr 21, 2026 By Shannon Davis In Mend
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.

If "stdio" is a Vulnerability, So Is "git clone" - Notes on Riding the AI Vulnerability Trend

Apr 21, 2026 By Ben Hirschberg In ARMO
A developer clones a repository and opens it in VS Code at 10:47 a.m. Before their cursor blinks, six different configuration file formats on disk have a chance to execute shell commands on the host. A.vscode/tasks.json with runOn: folderOpen. A.devcontainer/devcontainer.json with initializeCommand. A post-checkout hook already sitting in.git/hooks/. A postinstall line waiting in package.json for the next dependency install. A.envrc in the project root.

AI Penetration Testing: Protecting LLMs From Cyber Attacks

Apr 20, 2026 By David Ketler In Outpost 24
88% of organizations now regularly use artificial intelligence (AI) in at least one business function. While adoption of AI technologies has accelerated rapidly, security measures often lag. The rush to roll out AI has, in many cases, overshadowed essential testing and safety protocols. This is particularly a worry when AI and Large Language Models (LLMs) become deeply embedded within organizational workflows and systems in a way that most software isn’t.

Claude Mythos Just Killed Exploitability as a Security Signal

Apr 19, 2026 By Seemplicity In Seemplicity
The game has changed. For years, security teams used exploitability to decide what to patch first. If a vulnerability had a known exploit, it went to the top of the list. If not, it waited. But with the arrival of next-gen AI models like Claude Mythos, that strategy is officially broken. In this video, we discuss how Claude Mythos has collapsed the barrier to building working exploits. What used to take real skill and significant time can now be weaponized in minutes. When everything is exploitable, exploitability becomes noise.

Multiple Cross-Site Scripting (XSS) Vulnerabilities in Mailcow

Apr 17, 2026 By Jorian Woltjer In Aikido
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.
