I like to show what LLMs do and don’t do with and without human management, so here’s a near one shot of some honeypot data from Defused. We take two exploit packets and have Claude with Opus 4.8 analyze them. We did give it specific instructions to use the vendor CVE information rather than third party sources.

Ok so as I’m writing this I’m currently on a temporary ban from twitter…. the reasons for this I believe are more complex than one would expect. Full disclosure, I’m assuming the ban was in part due to AI but that is an assumption… but it’s the only realistic explanation I have. You might be thinking, who cares…. but bear with me….

Yesterday I ran a pentest against an RDP server, the process was ok but not amazing, I had to provide more help than I would have liked, resource consumption and the idea it should keep going…. wasn’t great. The process and output wasn’t terrible at all but it didn’t blow me away.
So today I wanted to see if Claude could take on as simple active directory lab! Now let’s be clear, there were I think one or two updates to the Claude client in that time! The Claude UI even changed look and feel! So I span up an AD lab I had made a while ago and got to work!

AI hype is everywhere, and don’t get me wrong, I’m a heavy AI user, I’m creating tools, conducting analysis and using AI constantly these days in my work a research. But I wanted to see, how well does an agent work if we try and give it the whole task to conduct with as minimal help as possible.

‘An improper neutralization of special elements used in an OS command (‘OS Command Injection’) vulnerability [CWE-78] in FortiSIEM may allow an unauthenticated attacker to execute unauthorized code or commands via crafted TCP requests.’

This analysis was conducted using data from Defused, enrichment from IPINFO and SHODAN and then analysis using an LLM (GROK) (so take the analysis with a pinch of salt):

‘CVE-2025-58034 is an OS command injection vulnerability (CWE-78) in Fortinet FortiWeb, allowing an authenticated attacker to execute unauthorized code on the system through crafted HTTP requests or CLI commands. It affects versions including FortiWeb 8.0.0-8.0.1, 7.6.0-7.6.5, 7.4.0-7.4.10, 7.2.0-7.2.11, and 7.0.0-7.0.11. The vulnerability has a CVSSv3 score of 6.7 (medium severity) and has been observed exploited in the wild, prompting its addition to CISA’s Known Exploited Vulnerabilities catalog.’

Another day another exploit in the wild it seems! (ok I’m a bit slow to this one). Using Defused Cyber’s Honeypots we have another packet to analyse:

There’s lots of talk from some people about how AI is going to destroy the world and needs to be regulated, like some kind of SkyNet has been created… Well I thought, aside from this being largely not reality, I would look into a history of ‘AI’ being used in cyber defence.

Ok, it’s late, and well I wanted to look into cyber attacks where social engineering is a key component combined with technical hacking skills.
There’s been a growing number of these style events, so I tasked GROK to create an assessment for me, let’s see how it did! Let’s both try and answer the questions:
Can GROK replace intelligence officers and can GROK help us defend better against social engineering + technical attacks? What do you think? (please take all of this with a pinch of salt… LLMs are known to make mistakes/hallucinate/lie in a very convincing manner)….
they look nice…. but looks can as we know, be deceiving! (is the entire blog just a social engineering experiment by me?)

Currently there appears to be a relatively significant cyber security incident at Marks and Spencer. So I thought I would give a demo of using AI (LLM, GROK) to create a timeline:
