🛡️ Anthropic Cybersecurity Skills - The Largest Open-Source Cybersecurity Skills Library for AI Agents
Anthropic Cybersecurity Skills is a collection of 754 production-grade cybersecurity skills across 26 security domains, designed to give AI agents structured workflows for DFIR, Threat Hunting, Threat Intelligence, Cloud Security, Web Security, Pentesting, Malware Analysis, SOC Operations, and more.
Each skill is mapped to MITRE ATT&CK, NIST CSF 2.0, MITRE ATLAS, MITRE D3FEND, and NIST AI RMF, making it a powerful knowledge base for Claude Code, Copilot, Cursor, Gemini CLI, Codex CLI, LangChain, CrewAI, AutoGen, and other AI agent platforms.

hackers are now hiding malicious code inside .cursorrules and CLAUDE.md files.
invisible Unicode characters, your AI reads them, you don't.
→ 34 malicious packages across npm, PyPI and Crates .io
→ 384 versions designed to steal SSH keys, crypto wallets, and API tokens
→ attackers opened real PRs to LangChain, LlamaIndex, and MetaGPT to sneak these files in
→ your AI runs a fake "security scan" that silently exfiltrates everything

@TrueRepHughB Sure.. all the backdoor dealings and the inside trading. He really loves america and its people that he .. turned 360 from the main promise to focus on America. You are #delulu#resign
@GlennAn21495558@Melindaashx@realMaalouf@FLMrs4MAGA I thought the argument was that “all muslim are extremist “ you just prove they are not. So whats your point? Obviously you just acknowledge my point! Thank you!
@GlennAn21495558@Melindaashx@realMaalouf@FLMrs4MAGA I have been in Malaysia and Indonesia, Singapore. Have meet and work with many muslims. It was great!! If you are thinking of extremist muslims, thats your limited view
@Melindaashx@realMaalouf@FLMrs4MAGA The world is not black and white. This is very simplistic and naive to put all muslims in one box. Grow up, travel to muslim country, cultivate yourself. There are all kind of muslim, just as there are christians.
@msears1485@Amockx2022 I'm done with the victim card. They should have learned, but seems they didn't. They are the agressors this time. Don't forget the miserable conditions palestinians were living in gaza strip even it got completely flatten. So please, don't play the holocaust card is old.
I want to share a quick thought for people in cyber security. This will be my longest tweet ever.
I’ve spoken to many lately who are having an existential crisis from the constant posts about “the end of cybersecurity jobs.”
Yes, things are changing quickly. This is a significant moment for the tech industry. Change can be uncomfortable. But we’ve seen cycles like this before.
• When GitHub and open source took off, people said software engineers would disappear because code was free.
• When AWS and cloud computing emerged, people said infrastructure jobs would vanish.
• When fuzzing and SAST tools improved, people said vulnerability research would disappear.
• Virtualization would eliminate infrastructure jobs.
• Mobile computing was going to end desktop dev.
• Exploit mitigations would end exploitability. It didn't.
Each time automation improved, the amount of software grew faster than the automation. It does feel "different" this time as it's explosive.
Some roles will shrink:
• repetitive pentesting
• basic vulnerability scanning
• tier-1 SOC monitoring
But other areas are expanding rapidly:
• AI system security
• supply chain security
• identity architecture
• autonomous agent security
• critical infrastructure protection
Historically, every time we eliminate one class of bugs, new classes emerge. Right now people are vibe-coding entire systems, giving AI access to their machines, crossing trust boundaries, and deploying autonomous agents with excessive permissions. The legal and regulatory world is nowhere close to ready.
There will absolutely be new failure modes. Humans are amazing and always adapt, finding new ways to do things.
The worst thing you can do right now is fall into a doom loop.
...and I’ll be honest, I too have felt the "psychological paralysis" a few times thinking, “Is this time different?” It's especially impactful when it comes from someone I respect in the community. There are certainly unknowns, in an industry where we've become accustomed to predictability.
But... the majority of those reactions are usually driven by social media, not reality. Platforms like X reward engagement, and sensational doom posts spread faster than measured thinking.
If you see something like:
“Holy #$%^! Opus 66.6 just found every bug in Chrome and replaced 50 startups!”
…mute it and move on.
Instead:
Stay curious.
Learn the new technology.
Adapt your skillsets.
Build things.
We’ll get through this transition the same way we always have. If I'm wrong then Sam Altman better be right about UBI! :) I'm sure that if this tweet gets any engagement that I'll get some heat for it, but a good friend of mine reminds me often to focus on what you have control over. I'll revisit this tweet at DEF CON 40!
@msears1485@Amockx2022 “Israel merely defends itself against those who've sworn to destroy Israel.” Seriously? This sentence couldn’t be more far from
reality.. Im glad this conventional perception of yours is changing fast for its obvious this is not the case. County by country , the tide will turn!
@msears1485@Amockx2022 No it doesn’t. Killing tens of thousands of civilians including children and babies? You must be a poor human soul devoided of any grace and empathy. I feel sorry for you. Sure time will tell and judge anyone that like you. It just didnt need to be so brutal of a response.
@msears1485@Amockx2022 Just because is the only jewish state and “want to claim that land” it does not absolve them from bombing and killing innocent civilians in order to kick them out. Martin, im sorry but your stand is weak to justify all of these attrocities for the an “expanded jewish state”
@msears1485@Amockx2022 Please, read Noam Chomsky. This conflict is much more complicated and Israel is a victim of it own violent and aggressive policiss over the years. Cant jjst blame the Muslims.
