ProxyLogon (CVE-2021-26855) PoC and Metasploit Module Released

The last two weeks we’ve seen major activity around the world with defenders and criminals rushing to respond to the recent zero day vulnerability patches and then the race to reverse engineer the kill chain to create an explot. We saw a PoC fairly early but it required that you reverse engineer some exchange DLLs and/or TAP the 443 to 444 interface on an exchange server to work out how to weaponise it. Things however have progressed, 8 hours ago we saw a metasploit module go online:

ProxyLogon – A god mode backdoor even when used…

Imagine

Imagine being able to read emails from any mailbox from a corporation! But everyone uses office 365… don’t they? Well ok even if that was the case (It’s not) then the RCE would come into play. An RCE into system level access to Exchange which is so heavily tied to active directory they are almost joined at the hip) is a killer foothold. However, you pain the scenarios they aren’t good!

All knowing and all powerful

Imagine if you could read everyone’s email! What could you do with this?

  • Steal IP
  • Steal data
  • Steal credentials
  • Extort, blackmail and bribe

The SSRF vulnerability enabling a threat actor to gain unauthenticated read access to mailboxes would be a killer tool for both nation state spies and criminals alike. Read more “ProxyLogon – A god mode backdoor even when used with READ only” →

WordPress Security Considerations

WordPress is one of the most popular content management systems in the world today. I believe it is about 35% of the market share globally. That is a lot of sites.

I have been using WordPress for years myself; some people give it some stick for being vulnerable but that is usually them referring to third party plugins. I like it because you can build a site easily, without having to spend ages and you can deploy it and migrate etc. without having a huge headache. Read more “WordPress Security Considerations” →

Combating Cyber Crime: Should we really be charging to…

Sensational Press or Cyber War Mongering?

I do not know Mr Martin, but I would assume that his role at NCSC and GCHQ would have given him a good insight into the realities of cybercrime, cyber terrorism, nation state affairs and how to effectively defend against cyber criminals (and other threat actors) so please read this blog as it is intended, it’s an analysis on the quoted statements and reporting style and general view of mine about current cyber war rhetoric, not an analysis of the person. Why am I writing this? Well, I am seeing an increased level of FUD, snake oil and cyber war rhetoric and I wanted to share some of my thoughts, opinions, and ideas in this space. For it is far too easy to call for war and in cyberspace do we even know what that means? Read more “Combating Cyber Crime: Should we really be charging to cyber war?” →

Extortion and Ransomware – A lethal Combination

A Brief History of Ransomware

Ransomware is not that new, I remember back during the msblaster incident I said to a friend, it is a good job whoever wrote this worm was not evil because they would have simply encrypted or deleted all the data post infection. Hell, I can barely remember when that was, I think it was late 2003. Ransomware has been around since the 1980s but not quite in its modern form (it started with the AIDS malware scam). Fast forward to the mid 2000’s and criminals were using encryption but that wasn’t a norm and things only really started to take a bad turn around 2012/2013 with Cryptolocker. The next major global events were WannaCry, NotPetya and Badrabbit. Read more “Extortion and Ransomware – A lethal Combination” →
