ransomware – PwnDefend

What if breach communications were honest?

Armed with my trusty sidekick, this morning I thought I would see what an LLM would make if I asked it to create public comms for common cyber incidents…. for basically every scenario… it really wanted to tell everyone no data was accessed! Which is amazing, because in almost every incident I’ve seen: Data is accessed!

In a business email compromise (BEC) scenario…. the clue is in the name, it’s already a compromise of confidentiality!

Defending Against Scattered Spider

Defending against different skilled threat classes is an important thing to consider when you are planning, designing and operating a business. I’ve used GROK (AI) to create an html page which has both information on the kill chains, but also looks at countermeasures. I’m experimenting lots with VIBE coding and LLM assisted content generation so hopefully this proves useful. I do feel it needs a more human touch added as well… but let’s see! life without experimentation would be dull would it not!

Avoiding an infinite incident response cycle!

Incidents are a part of life, but so is understanding the scope and bounds of an incident. One subject that comes up form time to time is how to define what is and is not ‘part of the incident’. Not everyone uses the same terms, language or definitions (which is true of many things in life). But when it comes to cyber incidents on the ground, details matter, but so do decisions!

Is the role of incident response to solve all security challenges and gaps in an enterprise? Should the recovery phase mitigate all threats? should the entire business be changed due to an incident and is that the role of the response team? When do you define what is and what is not part of the response vs what is a business change project?

What are the top Active Directory Security vulnerabilities I…

Ok so here’s the thing, I do NOT like getting pwn3d! I think you probably would rather your organisation does not too!

What I really don’t want to occur is a ransomware event! They suck, they are like a digital bomb going off.

So I’ve knocked up a quick list to get people thinking (these are NOT all the vulnerabilities I networks you should care about.. but they are some that could lead to a ransomware event!)

The Manual Version 2.0

Working in Cyber security can expose you to all kinds of information. I’m an offensive and defensive security architect and occasional (haha that’s daily right!) pew pew slinger (pentester) and I am also a threat intelligence practioner (CTI) (we need The Many Hats Club back!). Which is why sometimes when things appear on the internet I think I decide to take a look.

Some TOX Clients Leak Egress IP addresses

Some friends and I did some testing this evening with TOX clients. We wanted to take a look at PERSEC/OPSEC considerations for using TOX. I also had a sneaky suspicion that it might out of the box leak more than people would appreciate (just a hunch and you don’t know until you test right!).

So, we setup a test. In the test we had:

The RoyalMail Ransomware Saga

Last update we had was when LockBit released a transcript of a chat alleged to be between LockBit and the RoyalMail ransomware negotiator.

Thanks to Domonic far tagging me, we can see an update has occurred on the LB site:

Active Cybercrime Groups

Ransomware this, ransomware that! The problem is, you can be tired of the subject but that doesn’t mean the threat has gone away! So what are the currently active ransomware groups posting victims?

Well here’s a list of currently active group (Both Ransomware and Marketplaces) names who have ONLINE “DARK WEB” (TOR) hidden services online and who are posting victims or are markets:

Lockbit 3.0 and Royal Mail – Chats Published

The loss of availability Ransomware causes is enough to make your day/week/s bad, the loss of data, bad month/quarter or longer.

Lockbit posted “Royal Mail need new negotiator.” Followed by “ALL AVAILABLE DATA PUBLISHED !”

What we actually found is that they published the chat history:

I knocked this up quickly but I “think” it’s accurate. Use at own risk etc.
