#AutonomousAI #cybercapabilities are advancing rapidly, with the length of tasks #AImodels can complete autonomously doubling every 4.7 months since late 2024. This acceleration is evident in new models like #ClaudeMythos Preview and #GPT55, which significantly outperform previous trends. https://www.aisi.gov.uk/blog/how-fast-is-autonomous-ai-cyber-capability-advancing?eicker.news #tech #media #news

Another report confirming that #Anthropic #ClaudeMythos hype was just marketing bluff, it seems not much better than other similar tools. https://daniel.haxx.se/blog/2026/05/11/mythos-finds-a-curl-vulnerability/

🦊 Firefox Hardening: The AI Breakthrough

Mozilla just revealed how they patched 423 vulnerabilities in a single month—more than the previous 15 months combined. Here is the "too long; didn't read" on their new security strategy:

The Tool: Mozilla built an "agentic harness" using Claude Mythos Preview. It doesn't just scan code; it acts like a security researcher to find, reproduce, and verify bugs.

The "Cold Cases": The AI unearthed bugs that survived for 20 years, including deep-rooted flaws in XSLT and legacy HTML elements that traditional tools missed.

Sandbox Safety: A huge win for privacy—the system focused on "sec-high" issues to prevent attackers from escaping the browser sandbox to access your OS.

The Verdict: This isn't just hype. Mozilla is now integrating this AI-driven auditing directly into their daily build process to catch bugs before they ever reach a user.

The Bottom Line: Firefox just got significantly harder to hack, thanks to a massive AI-led cleanup of two decades of legacy code.

Vielleicht sollte Anthropic einfach mal den eigenen Claude-Code mit Claude Mythos auf Sicherheitslücken scannen...

The Register: NHS to close-source hundreds of GitHub repos over AI, security concerns. “The UK’s National Health Service (NHS) is ordering all of its technology leaders to temporarily wall off the organization’s open source projects over concerns relating to advanced AI and Anthropic’s Mythos. According to guidance shared internally within the organization and seen by The Register, GitHub […]

Der gute @TheMorpheus hatte genau das schon in einem Video thematisiert. Das wird unsere neue blühende Zukunft sein.

Wenn du nicht eingeladen bist, deine Infrastruktur und Software via AI testen zu lassen, bist du eben nahezu schutzlos gegen AI-Attacken. Und das verschiebt natürlich auch massive Macht zu den AI-Konzernen.

Da können wir noch so viel über digitale Souveränität faseln, gegen sowas hast du eben keine Chance.

Jag instämmer i vad @karlemilnikka och Peter rekommenderar organisationer om vad gäller #ClaudeMythos i detta avsnitt av #BliSäker. Men ser samtidigt risken att många säkerhetsavdelningar nu kommer fixera än mer på för dem tekniskt begripligt och externa hot, fortsätta prioritera ner det som redan i nuläget kostar sina organisationer enorma summor, och risker, i form av produktivitet och annan verksamhetsnytta.

De 2 viktigaste det handlar om är:

1 - Det ska vara lätt att göra rätt
2 - Kunskap

Anthropic verspricht "Problemlösungen jeder Art" durch ihre KI-Modelle. #ClaudeMythos soll entdeckte Sicherheitslücken zunächst mal erkennen.
