In case anyone is curious about who broke TLP, lied about it, and then blocked me, it’s this guy.

Eyal is exactly right. It has long been the case that threat actors would adopt the tools of pentesters. Now adversaries using LLMs are telling them that this is an authorized pentest and the LLM will often leave traces of that.
You can detect some AI-enabled attacks by searching for explicit indications of penetration testing. This happens because threat actors tell their LLMs they are performing authorized engagements even when using open weight models, or use pentesting harnesses like cyberstrikeAI, PentAGO, Hexstrike.

Updating blogs based on new information is normal and all naming schemes are bad in different ways; some are just less-bad.

Sometimes they’re good at it and sometimes not. I’m going to do an entire talk on this sentence from a Kaspersky report in August.

This was in no way a good use of my time but here’s the diagram which does not in any way resemble a Venn Diagram.
Badly spaced three bubble diagram connected by arrows to suggest a linear process. The bubbles are labeled “Terrorist Group”, “Terror Attack Victim” and “Society”. First bubble and arrow are red while the “Society” bubble is green. Arrows are labeled “the attack” and “Resultant Fear >> Political Pressure”.

Web server compromise. OST and commodity C2 frameworks. Hack and leak. Experimentation with new phishing filetypes. Cloud storage as infrastructure. More automation. More stages to evade sandboxes and more effort to evade analysis of a final stage Trojan that’s had development effort put into it.
Tweet from Steven Miller “In your opinion what are the biggest shifts in adversary tactics/behaviors in the last 10 years? Looking for high level, macro trends, backed by anecdotes or publicly documented examples.

Options-IT is a service provider for finance sector but…looking at their website they service traditional finance orgs, NOT the kinds of crypto orgs that DPRK focused on post-2018.

I’m sorry but “Many eyes makes all bugs shallow” is wrong but just completely an utterly unworkable unworkable in an adversarial context.

I notice you glossed over that it was Code Pink doing vandalism and that Code Pink is totally fine with genocide as long as it’s in China. Also would be helpful to note that last I checked, Pelosi isn’t in the Knesset or Israeli war cabinet. 🤷‍♂️

Nothing that DPRK received would offset the need for artillery and missiles in the short term leading up to a war. It only would make sense in the long term. If a full war broke out, everyone involved would lose, catastrophically.
