ICYMI: Our BloodHound t-shirt fundraiser is happening now! Add the BloodHound 8.0 shirt to your collection today! All funds raised will go directly to @HopeforHIE, the global voice for families affected by Hypoxic Ischemic Encephalopathy. 👕: ghst.ly/bh8-tshirt
@HackingDave Shhhhh! Don’t spoil the “surprise” for all of us 😅🤣
@vxunderground I dug about 0% into the topic besides skimming the post but am curious if the so called proprietary data comes from their US/other gov and mil clients as well or just the commercial side of the house 🤔
@HackingLZ @jamieantisocial Reminds me of some random past ADHD fueled project that attempted to be a half baked themed “personal toolkit” that ended up with sampson.py & some fish & abba zabba easter eggs before I got bored of it
Xbow raised $117M to build AI hacker agents, in @AliasRobotics open-sourced it and made it completely free. Github: github.com/aliasrobotics/… Paper: arxiv.org/abs/2504.06017
@Jhaddix Love it, I’m stoked for Spider-Man and the other Marvel stuff coming down the pipe as well! I also really enjoyed pulling this EoS collector/play boxes because I’m a sucker for pretty lands and space-themed stuff
Your devs aren’t just writing code, they’re holding keys to your kingdom. BloodHound now supports GitHub identities, so you can visualize access and control in your org’s dev pipeline. Check it out at github.com/SpecterOps/Git…
I'm releasing a backend for multi-agent AI systems that need to model complex non-linear problems. Kafka handles async agent communication, with ingestion plugins that route data to Neo4j, Qdrant, and MinIO. Check it out on the IBM X-Force GitHub! github.com/xforcered/Agen…
For anyone interested, Offensive COM hijacking is now available on YouTube. 🤠 youtube.com/watch?v=M_U2ne…
People have asked me who are cool and badass people to follow. Here is the all-star roster of researchers I love to follow: - @domchell, he is less "researcher" now, but he runs MDSec and he has a collection of brilliant researchers. He retweets a lot of really cool papers and malware stuff he finds. Following him helps us scout cool malware stuff - @SeamusHughes, not necessarily malware related, but he watches United States court system paperwork like a hawk. He has allowed us to stay up-to-date on cyber crime court documents which have not been disclosed (and other crazy stuff) - @jamieantisocial, the past few weeks, or months (memory is fuzzy), he's been memeing and highlighting malware research papers which has allowed us to draw our attention to cool papers we may have missed. - @TwoSevenOneT, no idea who this person is, but they retweet and post some wild Windows internals stuff. They don't post very often - @sixtyvividtails, no idea who this person is either, but they reverse engineer Windows A LOT. They've reverse engineered Windows so much so they've unironically identified inaccuracies in the Windows Internals series (bro is crazy) - @daaximus, this guy also does a lot of low-level Window stuff. I've had a lot of great conversations with him. He has helped identify new process injection techniques, helped me debug my code (turns out it was the compiler, he himself has identified problems with msbuild and ways to convince the compiler to work correctly), and other weird stuff - @Intel80x86, yes another weird low level Windows internals nerd. He made @HyperDbg. He has a habit of identifying changes in the Windows kernel and posting stuff I'm completely unfamiliar with. I don't feel like writing more. Here are other accounts that I really enjoy but don't feel like explaining why: - @mrexodia - @vxdb (not related to us) - @Now_on_VT - @BushidoToken - @James_inthe_box I'm missing some more people, but this is a pretty good start
@Jhaddix Is this a sneak peak for November by chance?
@owasp Thanks for sharing. Are seats limited to ~20 per course?
@HackingLZ @olafhartong @ElzeOpinions Already forgot where I jacked this from earlier, but if the shirts ain’t like this, they ain’t shit 😂
