Constrained Delegation Considerations for Lateral Movement
The abuse of constrained delegation configuration, whereby a compromised domain user or computer account configured with constrained delegation can be leveraged to impersonate domain users to preconfigured trusted services, is a common attack path in Active Directory. For each trusted service, a unique service ticket is used, that explicitly corresponds to the service type for which it was requested. For example, to access Windows file shares, a CIFS ticket is…
Left To My Own Devices – Fast NTCracking in Rust
When I got a new MacBook with an M1 Pro chip, I was excited to see the performance benefits. The first thing I did was to fire up hashcat which gave an impressive benchmark speed for NT hashes (mode 1000) of around 9 GH/s, a solid doubling of the benchmark speed of my old Intel MacBook Pro. But, when it came to actually cracking things, the speed dropped off considerably.…
SIM Hijacking
“533 million Facebook users’ phone numbers leaked” was one of the highlighted titles that flooded many social networks’ pages. The leak that was initially for sale in 2020 has more recently been released for free on a hacker forum containing mobile numbers, and a bunch of other related information. This news gave birth to websites like https://haveibeenzucked.com, where you could check if the Facebook data leak contained your data. (https://haveibeenpwned.com…
Android Application Testing Using Windows 11 and Windows Subsystem for Android
With the release of windows 11, Microsoft announced the Windows Subsystem for Android or WSA. This following their previous release, Windows Subsystem for Linux or WSL. These enable you to run a virtual Linux or Android environment directly on your Windows Operating System, without the prerequisite compatibility layer provided by third-party software. In this post I’ll show you how to use WSA for Android mobile application pentesting, such that you…
sensecon 2021 – wargames edition
If last year taught us anything, it was that we can move quickly to organise a fully online hacker conference in little over a month. This year our annual, internal hacker conference ran from the 16th to the 18th of September, was attended by 102 hackers from 9 countries across 2 timezones, and was once again filled with epic hacks and laughs! In this post I’ll tell you more about…
Building an offensive RPC interface
Using the Windows Remote Procedure Call (RPC) interface is an interesting concept when conssidering the fact that it allows you to call functions, over the network in a remote process. I wanted to better understand how RPC worked, and decided to build my own RPC interface to help with that. As a result, I wrote an RPC interface that will spawn a reverse shell given an IP address and a…
blackhat_defcon_virtual_vegas_2021.zip
Phew! This year’s hacker summer camp is packed with presentations from several hackers across the globe at Orange Cyberdefense. I can’t possibly go into all of the many details, but hope to give a somewhat compressed view of the highlights! This year we have a total of 10 representations. Four of those are DEF CON 29 talks, where two are main stage talks, one a demo labs talk and one…
Come do Wi-Fi!
Wi-Fi is everywhere and having a better understanding of it can fair you well! Over the years we have made various tools such as hostapd-mana to enable attacks against Wi-Fi, and then tools such as berate_ap for those people who don’t want to, or have to, learn how to use hostapd-mana. In our Unplugged: Modern Wi-Fi Hacking course you will be forced to shun the convenience of automated tools such…
Exploring The Fundamentals
We are excited to be presenting our Hands-on-Hacking Fundamentals (HHF) course at this year’s BlackHat USA 2021 conference. In our HHF course we explore the fundamentals required to grow your hacking skills where you can utilise your newly learned skills with practical, real world hacks in our custom lab environment. This blog aims to demonstrate the fundamentals of networking and scanning using the defacto Network Mapper “Nmap” which is one…
Our Enterprise Infrastructure Hacking Course
Here at Orange Cyberdefense, clients often ask us to test and help secure their infrastructure. We do this a lot. We test clients, we test ourselves, and we set up labs to test new ideas and tools. We’ve become quite good at this, if we say so ourselves, and would love to share some of the lessons we’ve learned along the way with anyone that would be interested. That’s what…
