I’ve not blogged in a while, but I wanted to put down a note of some useful tools people can use to help them combat cyber crime.
This isn’t going to be an in depth look at each tool, however I do want to, in the near future, try and do some demos/videos etc. of how to investigate potential/suspected or identified threats. I’ll drop a list of some of the useful tools below and also do a quick demo of investigating an event (from this blog)

This is a fast publish. Based on honeypot data from @SI_FalconTeam we can make some analysis:
In the lab we have attacked HTTP and HTTPS and have been able to get AUTH bypass. (thanks @leak_ix)

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:

Cyberwarfare in Ukraine was hyped as a MASSIVE thing, yet largely it’s been more bark and bite, but perhaps people need to understand that you can’t just “CYBER” a remote network, and even if you could, let’s say you get RCE on 30 networks in a country, so what? There needs to be value, purpose and something that will support other objectives, this isn’t a CTF.
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:

Ok read all that good. What we are talking about here is signing a DNS zone to “assure” that the client is getting DNS responses from the right ZONE data. DNSSEC does not encrypt the conversation between DNS client and DNS server. It does enable the client to be able to check if the data it gets back is valid. In short what we are doing is validating that the “data” being returned is authorized and not tampered with.

Adversary: Unknown, likely Criminal Actor/s
Initial Access Vector: Unknown/Unproven
Impact: ~3K+ Hosts have had Remote Code Execute and their ESXi logon pages changed (plus had encryption routines run to encrypt virtual machines, with varying success). A Second encryption routine has been deployed to some hosts; the threat actor is expanding/changing capabilities.
Risk: Further impact, Additional Threat Actors Exploit the vulnerability

Thousands of ESXi hosts around (some of the) globe have been encrypted by cyber criminals. This post is a fast publish showing some of what has occurred, it’s impact and now includes limited remedial advice.
If you have been affected by this ransomware event there is an attempted recovery script by CISA

Did you want to check out some of your detections? This isn’t everything of course but it’s a simple batch file to simulate a range of enumeration techniques used by actors like CONTI or LOCKBIT affiliates/operators:
