Your pentest report looks clean. That might be the problem.
Run automated pentesting long enough, and the new findings start to dry up. By the third or fourth run, fewer issues appear. The report looks stable. Leadership reads "stable" as "secure." It usually isn't. The work slows down. The risk does not.
That gap is what a The Hacker News webinar with Picus Security sets out to close.

On June 9, Anthropic released Claude Fable 5, the most capable model it has ever made, generally available. It also did something unusual: it shipped one model as two products, split not by capability but by a layer of safety classifiers.
Fable 5 goes to the public. Its twin, Claude Mythos 5, the same underlying model with the cyber safeguards lifted, stays locked to a vetted group of cyberView the full article

The activity has been attributed by Trend Micro to Earth Dahu (aka Gamaredon) and SHADOW-EARTH-066 (aka UAC-0226). It involves the exploitation of CVE-2025-8088, a path traversal flaw that allows anView the full article
University of Toronto researchers have built and tested a proof-of-concept AI-driven computer worm that uses a locally hosted open-weight large language model to reason its way through a network, generate tailored attack strategies for each target it encounters, and replicate itself, all without human intervention and without touching a commercial AI service.

Organizations have more visibility than ever. Growing tech stacks provide greater coverage, and network security teams are increasingly adopting AI and automation to help with routine tasks and reduce manual effort.
But the same challenges persist. Outages still last hours, causing significant financial losses, operational disruption, and reputational impact. Threat response and mean time toView the full article
A malicious website can work out which sites you visit and which apps you open, using nothing but JavaScript and the timing of your SSD. The attack, called FROST, needs no native code, no extension, and no permission prompt.
You open the page, leave the tab sitting there, and it watches the drive for contention in the background.
Researchers at Graz University of Technology built it andView the full article
The Miasma supply chain campaign has sparked a fresh attack wave called Hades, this time involving 37 malicious wheel artifacts across 19 packages in the Python Package Index (PyPI) registry, as the Mini Shai-Hulud-style attacks continue to be refined and splintered to target specific ecosystems.

Monday again. The weekend was meant to be quiet. It wasn't. Last week had poisoned packages, a broken AI helper, and a worm tearing through repos. The ugly part: basic tricks still worked.
A chatbot got fooled. A bot token got leaked inside the malware. The same old mistakes showed up again. And while everyone chased the loud stuff, quieter attackers sat in inboxes for months, reading mail andView the full article
Phishing has always been a numbers game. AI has turned it into a volume machine.
Attackers can now create convincing emails, fake login pages, and tailored lures in minutes. Every polished message adds another case for Tier 1 to review, another link to inspect, and another alert that cannot be dismissed at a glance.

Mythos is real. I know a big chunk of the industry thinks it's a marketing stunt, and I get why. I get it. But I've seen the findings, and they're bad. These aren't "whoops, this line right here is wrong, and that's RCE." They're novel combinations of a few dozen issues out of thousands of things every SAST scanner already finds, chained together into something much worse. It's real creativity,View the full article
