The EU is advancing legislation requiring all messaging platforms to scan private messages, even in encrypted apps like Signal/WhatsApp/Telegram. 600+ security researchers oppose ChatControl for being technically flawed. Learn more about it 👉 metalhearf.fr/posts/chatco... #ChatControl #privacy

I did a bit more looking into the upcoming bitnami deprecation. The images are still getting millions of pulls a week, so depending on exactly what tags vanish next week, there could be a lot of broken deploys on the 28th! raesene.github.io/blog/2025/08...

@micahflee.com thank you for the amazing and inspiring defcon talk

I arbitrarily picked a list of 50 talks I'm most excited about that are happening next week at DEF CON / Black Hat / BSides LV / The Diana Initiative. I'll also add recordings/slides to this list when they become available!

Getting ready for DEF CON next week! ✅ Slides ✅ Demos ✅ Custom shirt designed for the occasion

By making minor changes to command-line arguments, it is possible to bypass EDR/AV detections. My research, comprising ~70 Windows executables, found that all of them were vulnerable to this, to varying degrees. Here’s what I found and why it matters 👉 wietze.github.io/blog/bypassi...

@anssi-fr.bsky.social Il serait bien d'utiliser votre nom de domaine officiel comme nom d'utilisateur Bluesky (bsky.social/about/blog/4...), autrement il est impossible de savoir s'il s'agit d'un compte légitime Idem pour @cert-fr.bsky.social

L'ANSSI vient de sortir un rapport sur la menace dans les environnements cloud, en Français : www.cert.ssi.gouv.fr/uploads/CERT... Au programme : • Menaces ciblant les fournisseurs • Menaces ciblant les utilisateurs finaux • L'usage que les attaquants font du cloud @anssi-fr.bsky.social

A refreshing perspective. Anyone has good resources on Western APTs? I remember reading from a French group that's likely state-sponsored (coucou la DGSE) but that's about it citizenlab.ca/2015/03/morg...

@dirkjanm.io Do you have any Europe-based training planned in the coming months? (besides the Insomnihack one I will unfortunately be unable to attend - such a shame as I live in Lausanne)

What are some open source projects related to security that may use support/funding?

Lately, every BSides seems to have a talk on reframing security teams as a “Department of Yes” We don’t hear nearly as much about the value of a well-considered, strategically deployed “No” I've pulled together guidance on giving a better, more constructive No: ramimac.me/saying-no

2024 saw the launch of our revamped toolkit! Thanks to amazing Toolkit Maintainers and Guardians, you can find a database full of useful free-to-access tools. Complete with complexity ratings and clear descriptions, the toolkit is a one-stop shop for investigations. bellingcat.gitbook.io/toolkit

I've spent dozens of hours reading State of Cloud Security reports You know, the ones that use data from their CSPM product And I've realized the findings substantially reflect how well that tool helps customers secure their clouds I wrote up some examples, both good and bad (🔗 in 🧵)

Never thought I'd read an headline like that one day

"Escalating privileges to read secrets with Azure Key Vault access policies" by @siigil.bsky.social securitylabs.datadoghq.com/articles/esc...

New research: We've been monitoring a threat actor publishing dozens of trojanized GitHub repositories targeting threat actors, leaking hundreds of thousands of credentials along the way securitylabs.datadoghq.com/articles/mut...

Threat actors spread info stealing malware through 1) GitHub-hosted PoC exploits for CVE vulns and 2) phishing emails targeteting 2,700 addresseses scraped from the arXiv research platform. The professional grade istealer stole 390,009 creds, likely from bad guys. arstechnica.com/security/202...

Supply-chain attack in the ultralytics PyPI package: github.com/ultralytics/... An attacker opened a pull request and pushed a commit with a malicious name, leading to CI code injection. They then backdoored versions 8.3.41 and 8.3.42 with code downloading a second-stage binary from GitHub

Apparent supply chain attack on Ultralytics, a popular AI Python library. Threat actor managed to insert cryptojacking functionality into specific versions (which have since been removed from PyPI). github.com/ultralytics/...

Exclusive: The backdoor inserted in v1.95.7 adds an "addToQueue" function which exfiltrates the private key through seemingly-legitimate CloudFlare headers. Calls to this function are then inserted in various places that (legitimately) access the private key.
