Big shoutout to Coinbase and other companies taking this approach, ensuring cyber security professionals have plenty of work for the foreseeable
This is an email I sent earlier today to all employees at Coinbase: Team, Today I’ve made the difficult decision to reduce the size of Coinbase by ~14%. I want to walk you through why we're doing this now, what it means for those affected, and how this positions us for the
Unfortunately most of the execs at these bug bounty platform fail to understand one thing: Your platform isn't your product... your hackers are. 🤷🏽♂️
built a web interface for Obsidian.md so you can access your vault from any browser using cloudflare tunnels + your own hostname. No more being stuck with notes on one machine, no installing clients on work computers you don't control 👀 👇 github.com/PatrikFehrenba…
Breaking: Microsoft plans to load Copilot inside File Explorer on Windows 11. References in preview builds point to “Chat with Copilot" and “Detach Copilot" in File Explorer. Right now, Copilot in File Explorer shows up only when you right-click files and the Copilot app is
[RELEASE] As promised, I’m releasing the first blog post in a series. It covers the gaps still present in current stack-based telemetry and how Moonwalking can be extended to evade detection logic and reach “on-exec” memory encryption. Enjoy ;) klezvirus.github.io/posts/Moonwalk…
Venom C2 tool drop! 🐍 During a recent red team engagement we needed a simple python agent that needs no dependencies to setup persistence on some exotic boxes we landed on. Some had EDR so we didn't want anything off-the-shelf. The server, agent, and client were made mid-engagement and kept our foothold for weeks. I have no use for this anymore, so thought i'd share it instead of letting it evaporate into the /dev/null. Link to boku7/venom GitHub repo : github.com/boku7/venom
Labour's 1984 shit show is already showing cracks and backfiring. Can't wait to see the shit show Digital ID gets compromised because they rushed to implement something no one wants...
Discord has begun sending e-mails notifications about a cybersecurity incident which occurred September 20th, 2025. It appears people who submitted support tickets are the ones primarily impacted. Literally peoples entire identity stolen from this shit
It gets better ;) I totally forgot about this little persistence method, lol
Hahaha, wow... 😮 If you leave App passwords enabled and enforce MFA through per-user MFA, the MFA enrollment wizard actually makes the user to create an app password 🤯
AWS quietly updated T&Cs to ban “Fireprox”style use of API Gateway closing a handy pentest trick. @ZephrFish and @TurvSec already rolled alternatives such as Omniprox and Flareprox. Banning tools only hampers legit testers, attackers will proxy anyway.
This release is probably going to be one of our biggest and most impactful! Kudos to the team @peterwintrsmith @modexpblog @s4ntiago_p @GigelV41464 @saab_sec 🙌

PDQ SmartDeploy versions prior to 3.0.2046 used static, hardcoded encryption keys for cred storage. Low-privileged users could potentially access admin creds from registry or deployment files. @unsigned_sh0rt unpacks his testing in his latest blog post. ghst.ly/4mjyuvw

PSA to anyone struggling, don't be told that "you're just worried", "you're just feeling sad", "you're overthinking things"... depression, anxiety, OCD, ADHD, Autism are killers. Talk, and advocate for yourself!
