WireSocks for Easy Proxied Routing

I built some infrastructure that you could deploy and use to easily tunnel from arbitrary sources over a proxy such as SOCKS, using anything that can run WireGuard. This is convenient in cases where it would be nicer to have a full network route to a target network (with working DNS) vs just having application specific proxy rules. In this post I’ll elaborate a bit on that idea. If you…

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…

thumbscr-ews – a python EWS tool

Something I have found myself doing more and more often is using Exchange Web Services (EWS) to bypass 2FA. I do this so that I could look through mail for accounts I have compromised. The 2FA bypass is due to a common misconfiguration which can leave EWS unprotected, and has been known about for ages, mostly from the Black Hills post in 2016. However, most of the tooling appears to…

Pass-the-hash WiFi

Thanks to a tweet Dominic responded to, I saw someone mention Passing-the-hash when I think they actually meant relay. The terminology can be confusing for sure, however, it made me realise that I had never Passed-the-hash with a Wi-Fi network. So having learnt my lesson from previous projects I first made sure this was possible for NT -> MSCHAP by looking at the RFC. 8.1. GenerateNTResponse() GenerateNTResponse( IN 16-octet AuthenticatorChallenge,…

PEAP Relay Attacks with wpa_sycophant

Back in 2018, I was interested that MSCHAPv2 and NTLMv1 hashes crack using the same algorithms, and wanting to get onto the WiFi of one of our clients, I naively thought “Surely if you can relay NTLMv1 and it uses the same crypto as MSCHAPv2, you should be able to relay MSCHAPv2!”. The resulted in the creation of wpa_sycophant (and its helper berate_ap) to perform PEAP relay attacks. It was…
