I've been hacking on a new Windows Named Pipe tool called PipeTap which helps analyse named pipe communications. Born out of necessity while doing some vulnerability research on a target, its been super useful in reversing it's fairly complex protocol. :)

Reverse engineering Microsoft’s SQLCMD.exe to implement Channel Binding support for MSSQL into Impacket’s mssqlclient.py. Storytime from Aurelien (@Defte_ on the bird site), including instructions for reproducing the test environment yourself.

A screenshot of two windows. The top is a view of the Microsoft SQL management GUI showing that “Extended Protection” is enabled for NTLM authentication. The bottom is a terminal showing an invocation of Impacket’s mssqlclient.py successfully connecting using channel binding.

Adriaan was struggling to get an interactive shell on the *nix application server he had popped, so he wrote a turn-based mini binary to give you a semi-interactive shell in restrictive environments. Writeup & code are at

Quite stoked to be speaking at @defcon.bsky.social 33 this year, presenting: "7 Vulns in 7 Days: Breaking Bloatware Faster Than It’s Built".

Reversing, exploits, disclosure pain - it has it all, and it's going to be fun! 💥

See ya soon Vegas. ☀️

I was talking with someone about dependency confusion and suply chain attacks and I was confused myself with the feasibility of doing this in 2025, so I decided to take a practical aproach and create my own tool 🔨 to detect Orphan and Mispelled packages 📦: sensepost.com/blog/2025/de...

Wifi hacking can be a useful tool, but people are out here grinding on WPA2 handshake cracking tutorials & menu driven attack tooling. When we built the 3rd and latest iteration of the wifi hacking course for BlackHat - we did it to show what really works and how it really works. 1/7

Unsatisfied with merely relying on reFlutter to do its magic, Jacques dove deep to understand how Flutter's SSL pinning in Android works, and how to intercept it with Frida.

Whipped together a SOCKS5-over-any-transport feature today for the c2 & implant used in @sensepost.com purple teaming / emulation exercises.

Here I have a cURL request, over an ICMP channel, funnelling HTTP requests in and out via our implant :D

Fun! 😄🔥
C2 console logs showing a SOCKS5 proxy having started on port 1800 Implant logs showing an ICMP channel enabled, HTTP channel disabled and a proxy server started targeting the ICMP channel. cURL configured to use a SOCKS5 proxy (pointing at the C2), targeting an IP on the other side of the implant.

Dropping Teams malware via the browser’s cache - part II of Aurélien’s Browser Cache Smuggling covers his Insomni’hack talk with end to end weaponisation sensepost.com/blog/2025/br...

Demo: youtu.be/tIveWYfYcCI
A screenshot from the demo video on YouTube showing the final state. There are four windows. Firefox open on an innocent looking page with the heading “Socrates: The Father of Western Philosophy”. Below it is a PowerShell terminal that was used to find the malicious DLL in the browser’s cache, and move it to c:\users\windev\appdata\local\Microsoft\Teams\current\VERSION.dll On the right is process explorer showing Teams running as normal with no malicious subprocess. Lastly the bottom window is a cmd terminal showing the reverse shell having connected and giving access to the command line of the victim host.

Reino takes his NoSQL injection series a bit further with (maybe) new techniques for more efficient error based NoSQL injections in this follow up post: sensepost.com/blog/2025/no...
NoSQL error-based injection Reading time ~6 min Posted by Reino Mostert on 15 March 2025 Categories: Database, Nosql injection, Injection, Nosql TL;DR How to do NoSQL error-based injection In this second blog post on NoSQL injection, I discuss how to do error-based injection. I think this might be a novel approach – at least my Google search-fu isn’t finding anything.

(v3 of this skeet because there's no edit button and I need a proof reader)
Syntax injection into the JSON query filter (New Stuff) In this case, the developers are using string concatenation, or more likely string interpolation to construct the query filter, before making it into a JSON object, and passing it to MongoDB. We can thus add in our own query conditions. This is a bit of a game changer from operator injection, since we can now query on the fields we want, instead of being stuck inside an existing field.
