[Anthropic @AnthropicAI]

The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees.

The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance.

Access to all other Claude models is not affected.

We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible.

#ESETresearch released its latest APT Activity Report (Oct 2025–Mar 2026): 🇨🇳China-aligned groups focused on Venezuela, Gulf states, and AI & robotics industry in 🇰🇷South Korea, while 🇰🇵North Korea-aligned APTs targeted the nuclear sector. Full report: https://t.co/5Dzgqwuz9q

The mystery of Fast16 has been solved by @symantec and physicist @DAVIDHALBRIGHT1. Fast16 changed data produced by simulator software to trick Iranian engineers into thinking their nuclear weapons designs were bad. It didn't predate Stuxnet but was developed around the same time

Finally I can post my fast16 memes

the fast16 malware was almost certainly targeting spherical implosion simulations.

I just released our kernelCTF VSock 0-day write-up with @_qwerty_po . (exp196/exp197, CVE-2024-50264)
https://t.co/8UpGrVcDFF

We made history by being the first to exploit VSock in kernelCTF, expanding its known attack vectors. 🥳

It’s a pretty *simple* race condition, right?

My first #Lazarus report at #Kaspersky is out ! The newly discovered #CookiePlus is a plugin-based malware that has the ability to download both DLL and shellcode.

It was a great experience working with great coworkers and learning a lot.

[Microsoft Threat Intelligence @MsftSecIntel]

Based on our findings and those reported by governments and other security vendors, Microsoft Threat Intelligence assesses the Russian nation-state actor we track as Secret Blizzard has used the tools and infrastructure of at least 6 other threat actors during the past 7 years.

More on this!

“…Insikt Group has identified over 60 unique TAG-110 victims, primarily in Tajikistan, Kyrgyzstan, Turkmenistan, and Kazakhstan.”

“…likely linked to the Russian cyber-espionage group BlueDelta, also known as APT28 or Fancy Bear.”

Just gave a talk about the Nearest Neighbor Attack at #CYBERWARCON and had a great time detailing our findings. This was a lot of great work by our @Volexity team and special thanks to @5ck and @tlansec for the long hours working on it! Def. one of our wildest #DFIR engagements!

[Andy Greenberg (@agreenberg at the other places) @a_greenberg]

Russian spies—likely Russia's GRU intelligence agency—used a new trick to hack a victim in Washington, DC: They remotely infected another network in a building across the street, hijacked a laptop there, then breached the target organization via its Wifi. https://t.co/Z0ekHlHWWy

[Volexity @Volexity]

.@Volexity’s latest blog post describes in detail how a Russian APT used a new attack technique, the “Nearest Neighbor Attack”, to leverage Wi-Fi networks in close proximity to the intended target, while the attacker was halfway around the world.
