Ransomware Defence Checklist – Part 1 : Initial Access

Defending the Realm

We keep seeing organization get hit, in some kind of a sick way I think me and some of my friends in the industry are bored with the over dramatic responses of “sophisticated” “advanced” and “unpreventable” because most times the kill chains simply are not like this. But still the onslaught keeps coming. Well I know this much, whilst I would love to deploy with the team and harden everyone’s networks that simply isn’t possible. So what we thought we would do is write something to try and spread the knowledge a bit further and hopefully have some positive impact.

Ransomware 101

It’s not just that your data will be encrypted, it will likely be exfiltrated and sold. You will likely have access sold, data sold and be extorted. The Ransomware business model is adapting to defender responses. Even if you can restore from backup they will likely try and attempt to extort.

The grass is always greener, until it is not

A PwnDefend Story – Day 7

It is a blur so far, I figured after the last place the grass would be greener, surely no one else has that many security challenges. I did some due diligence during the interview process, they seemed very confident about having certifications and that they took security seriously. hell, that should have set some red flags off but even the cynical sometimes hope that it is as someone says.

I have started to work myself around the board and I am making friends with people, my diary is filled with zoom calls and my notebook is already many pages deep.

You cannot make this stuff up though, day two and I’ve dealing with a business email compromise incident, the phishing page was not even in good English but then it only takes a second or so whilst in a meeting to not quite realise your running on autopilot so you cannot blame people. Hell, the branding was copied so we know it was a targeted phish. It would have been nice to at least had centralised logs for the team to analyse though.
