We worked with @_dirkjan to get this as an exclusive into Outflank Security Tooling with a new tool called ROADtune. ROADtune allows red teamers to: - bypass CAP by faking device compliance registration - loot secrets from applications pushed to compliant devices Cool stuff!

Pretty proud of this one, took a lot of work. And no, this device does not exist 😎
if you’re going to sector, let me know! i’ll be there this evening through friday

For anyone who's badge I managed to "Pwnz0rz111" today at RedTreat, you can revert back to the "original" FW by booting the badge, and once my spooky purge face shows up, press the middle button (the up button) and then the top button (the select button). The image just overlays…
And thats a wrap of #RedTreat 2024 2 days of hardcore red teaming research and meeting other rt researchers and operators. Mind still 🤯 processing some of the discussions! Thanks to all the attendees and speakers for being present at our little conf! /c @MDSecLabs @OutflankNL

Who’s the real #GrimResource? Spoiler: It’s us! 😏 Here's our latest blog on using MSC files for initial access: outflank.nl/blog/2024/08/1… Fun fact: @elastic’s post on this technique came from a sample caught by a blue team, originally used by a red team through our OST offering.
OST's Stage1 C2 is now Outflank C2, an optimised, OPSEC focused custom C2 framework with: •Native implants for Windows, macOS and Linux •Dynamic code exec •Proxying support •Peer-to-peer C2 between all three implants Get more info at bit.ly/4cgw8rl
Sore muscled but satisfied looking back at the first #InfosecKartCup With 135+ people this was a fantastic social event for infosec profs in NL. Always great to connect offline! Thank you all for attending. Thank you @Northwave_Sec for co-organizing. See you next year?
Been looking forward to this. @max__grim and @c3c talking about the winds registry @WEareTROOPERS
#TROOPERS24 badges arrived. This is insane.
Outflank's own @ptrpieter will be at @XOffensive21584 in Athens! Check out his session on June 21st at 11:00am, where he'll be giving the TL;DR on lessons learned from thread led digital #redteaming
