I love sharing content, ideas, thoughts, theories and hopefully some of the things i’ve picked up along my career so far! I imagine most people wouldn’t say I had a traditional approach to consulting and my content sharing approach is generally quite simmilar, so in a mad moment a week ago I decided to see if I could go through the Comptia Pentest+ course. Why did I decide to do this you ask! Well that’s a bit more complex…Read more “mRr3b00t’s pentest 101 draft notebook”
Many of you will know I’m a massive fan of learning all the things, but also I’m a huge fan of sharing intel, knowledge and experiances because I know when you are starting in a field, the world can seem too big to know things! So to this end, I’ve put together a quick list of tools that I believe are required you have some knowledge of for the PenTest+.
Where possible links to tools and download locations have been provided. Clearly you can deploy a security testing distro such as Kali Linux, Parrot etc. buy you may want to simply install Ubunt or use Windows and WSL 2. Read more “Learn all the things!”
Windows DNS Server
This is really a major issues for Active Directory Domain Controllers.
CVE-2020-1350 : https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2020-1350
We can see there are 2,133 servers on Shodan that are exposed however this exploit doesn’t rely on exposure, a client request from inside the network to a malicious DNS server could be used to exploit the domain controller.

If your can’t take an honest view on real challegnes we face you probably want to click the back button now!
The three laws of IT apply:
- Software has bugs
- Hardware breaks
- Humans Make Mistakes
It doens’t mean however we shoulnd’t strive to do better! so now that’s out of the way here’s a fast blog on shit you should care about and patch (if you haven’t already!)
Also please note these are not ALL the vulnerabilities you should care about, just some choice ones that are enough to make you cry!
“Don’t worry, we’ve got that behind a firewall or VPN!” is something I’ve heard a lot over the years, which to be honest is starting to look more and more worrying. Think that’s just me giving my opinion? Well think again, here we have collated SOME of the vulnerabilities in security products which if unpatched/mitigated really leave you. well quite insecure!Read more “Perimeter Security Vendor Hell – Unauthenticated RCE’s and other crazy you didn’t want in your security devices!”
CVE-2020-5902 Defensive Guidance (FAST publish)
This week’s been a whirlwind, once again teams of people scrambled to help defend networks from criminals trying to abuse CVE-2020-5902.
If you want to see this in action check out my video on youtube!
The main issue (other than the vulnerability itself (path traversal and unauthenticated remote code execution) is exposing management interfaces to the internet (or other insecure/untrusted networks). Yesterday we looked at IOCs in the “/var/log/audit” file.
Now a sensible attacker who has ROOT level access would have likely cleared their tracks! However, a good sysadmin would have the logs shipped off the device!
I’ve spent the last 24 hours (including a sleeps) gathering intel, testing in the lab and looking at what the path traversal and RCE for the F5 BIG-IP as outlined in CVE-2020-5902 looks like.
Well I’ll be honest.. the whole scenario is a bit of a bloody mess! We’ve got people leaving management interfaces exposed to the internet, we’ve got a vulnerability that’s incredibly old in a security appliance (it’s not exactly uber 1337 either) and we’ve had the release scenario that’s probably ruined peoples weekends and weeks (I’m not going into an Offensive Securitry Tools debate/argument, if you want that go talk to a brick wall or someone else!)
I’m in a very fortunate position (currently) whereby I have not had to look for a ‘job’ since I was much younger. I do however remember what a soul crushing experience that used to be. I’d send emails, I’d write letters, eventually after stone walls of silence and rejections because of not enough experience or qualifications. I just remember job hunting as a depressing experience and I can’t really imagine that’s changed a great deal over time!
When I was younger, I was a year ahead of myself in school (due to the event of not dying and going to a very lovely first school). I was never very academic when I was younger, but I loved games and I learnt very quickly (this was with our first Amstrad) that I loved computers and wasn’t too shabby with them.Read more “If I had to go and find a job”
