Architecture

The difference between what can be vs what often…

I’ve travelled all over the internet, I’ve worked with logs of organisations from banks through to small ISVs and one thing I would say is fairly universally true. What can be isn’t what is.

There’s a lot of different operating models and technologies in the world. There’s logs of differen’t specifics. This diagram here is not mean’t as a refrence architecture but more as an indicator.

There is also a massive reality people must understand, cyber good most definatley costs more at the point of deployment than cyber bad. Cyber bad’s ROI is truly variable and in mind mind is too hard to measure. For one org with cyber bad can experiance a significant breach (and cost) and another may have lady luck on their side.

Log4Shell exploitation and hunting on VMware Horizon (CVE-2021-44228)

It’s crude so also look for the modified timestamps, recent unexpected blast service restarts and if you have process logging go and check for suspicious child processes over the period. Once you have checked, run a backup, then if they aren’t patched, patch the servers! (i know patching isn’t as simple as just patch!)
