Microsoft has banned Nightmare Eclipse from GitHub: github.com/Nightmare-Eclipse… This is the researcher who disclosed several zero-days after Microsoft also deleted their MSRC account. They have now moved on to GitLab: deadeclipse666.blogspot.com/ (h/t to: @[email protected])

Virtual private networks #VPN are increasingly used to bypass online age verification. Protecting children online is a priority, with new rules being implemented requiring a minimum age for access to some services Read👉 link.europa.eu/FGfr6C #DSA @EP_Justice @FZarzalejos
Readers added context they thought people might want to know
According to the University of Michigan research paper "Multi-perspective study of VPN users and VPN providers," 82.1% used VPNs "to protect myself from various threats/adversaries." No research shows that VPNs would be increasingly used to bypass online age verification. censoredplanet.org/papers/VPN-Sur…

🚨 @GrapheneOS ÉCRASE 3 NOUVELLES FAILLES LINUX CRITIQUES 🔥 Copy Fail, Copy Fail 2 et Dirty Frag? Trois vulnérabilités kernel Linux fraîchement dévoilées… et GrapheneOS les ignore totalement. ✅Les politiques SELinux d’AOSP bloquent l’exploitation des 3 bugs à la racine. ✅La config GKI standard d’AOSP désactive déjà 2 des 3 fonctionnalités vulnérables. C’est pas de la chance, c’est du travail de dingue: réduction massive de la surface d’attaque grâce à un SELinux ultra-granulaire + suppression chirurgicale des features inutiles dans le kernel. GrapheneOS va encore plus loin : • ioctl autorisés au cas par cas •user namespaces et io_uring totalement interdits aux apps ET à presque tout le système •seccomp-bpf en renfort Résultat ? Ces failles logiques mémoire qui auraient pu tout casser sur n’importe quel autre Android… sont mortes dans l’œuf sur GrapheneOS. ➡️Oui, les élévations de privilèges kernel Linux restent hyper fréquentes. ➡️Oui, la plupart sont des corruptions mémoire (matraquées avec memory tagging hardware + zero-on-free). Mais même sur ces bugs “logiques”, l’approche de GrapheneOS fait toute la différence. Linux, c’est un océan de code qui tourne en full privilege sans aucune isolation. Dans un microkernel, ces 3 failles auraient été isolées dans des processus séparés. Le modèle monolithique est clairement à bout de souffle. La vraie solution à long terme ? Un langage memory-safe + virtualisation hardware qui progresse à vitesse grand V sur les smartphones. GrapheneOS prépare déjà le terrain. On peut encore durcir énormément le kernel Linux… mais il est clair qu’il faudra le remplacer un jour. 𝐆𝐫𝐚𝐩𝐡𝐞𝐧𝐞𝐎𝐒 𝐧’𝐚𝐭𝐭𝐞𝐧𝐝 𝐩𝐚𝐬 𝐪𝐮𝐞 𝐥𝐚 𝐩𝐫𝐨𝐜𝐡𝐚𝐢𝐧𝐞 𝐟𝐚𝐢𝐥𝐥𝐞 𝐚𝐫𝐫𝐢𝐯𝐞. 𝐈𝐥 𝐜𝐨𝐧𝐬𝐭𝐫𝐮𝐢𝐭 𝐥’𝐚𝐯𝐞𝐧𝐢𝐫 𝐝𝐞 𝐥𝐚 𝐬𝐞́𝐜𝐮𝐫𝐢𝐭𝐞́ 𝐦𝐨𝐛𝐢𝐥𝐞. 𝐀𝐮𝐣𝐨𝐮𝐫𝐝’𝐡𝐮𝐢. 🔒🛡️💪🏼 #GrapheneOS #AndroidSecurity #LinuxKernel #PrivacyMatters

‼️🚨 Microsoft calls this "intended behaviour," so here we go. How to dump the credentials of every user stored in Microsoft Edge: 1. Open Edge. Don't browse anywhere, just open it. 2. Flip to Task Manager, find Edge, expand the task. 3. Highlight the "browser" sub-task, right-click, and choose "Create Memory Dump." 4. Open the dump file and look for credentials. The logged-in Windows user can dump every stored Edge credential with no additional rights. Which means any malware that user executes has those credentials for the asking.

Windows defender has been compromised. right now there is a public unpatched exploit that gives any app on your windows PC full system admin access. no password. no popup. nothing your antivirus doesnt stop it. your antivirus IS the exploit. windows defender is the attack vector ransomware gangs can use this to encrypt your entire machine and steal every saved password, browser session, and discord token you have. fully patched windows 11. real time protection on thread

🚨 CRITICAL: Active supply chain attack on axios -- one of npm's most depended-on packages. The latest [email protected] now pulls in [email protected], a package that did not exist before today. This is a live compromise. This is textbook supply chain installer malware. axios has 100M+ weekly downloads. Every npm install pulling the latest version is potentially compromised right now. Socket AI analysis confirms this is malware. plain-crypto-js is an obfuscated dropper/loader that: • Deobfuscates embedded payloads and operational strings at runtime • Dynamically loads fs, os, and execSync to evade static analysis • Executes decoded shell commands • Stages and copies payload files into OS temp and Windows ProgramData directories • Deletes and renames artifacts post-execution to destroy forensic evidence If you use axios, pin your version immediately and audit your lockfiles. Do not upgrade.

Software horror: litellm PyPI supply chain attack. Simple `pip install litellm` was enough to exfiltrate SSH keys, AWS/GCP/Azure creds, Kubernetes configs, git credentials, env vars (all your API keys), shell history, crypto wallets, SSL private keys, CI/CD secrets, database passwords. LiteLLM itself has 97 million downloads per month which is already terrible, but much worse, the contagion spreads to any project that depends on litellm. For example, if you did `pip install dspy` (which depended on litellm>=1.64.0), you'd also be pwnd. Same for any other large project that depended on litellm. Afaict the poisoned version was up for only less than ~1 hour. The attack had a bug which led to its discovery - Callum McMahon was using an MCP plugin inside Cursor that pulled in litellm as a transitive dependency. When litellm 1.82.8 installed, their machine ran out of RAM and crashed. So if the attacker didn't vibe code this attack it could have been undetected for many days or weeks. Supply chain attacks like this are basically the scariest thing imaginable in modern software. Every time you install any depedency you could be pulling in a poisoned package anywhere deep inside its entire depedency tree. This is especially risky with large projects that might have lots and lots of dependencies. The credentials that do get stolen in each attack can then be used to take over more accounts and compromise more packages. Classical software engineering would have you believe that dependencies are good (we're building pyramids from bricks), but imo this has to be re-evaluated, and it's why I've been so growingly averse to them, preferring to use LLMs to "yoink" functionality when it's simple enough and possible.
LiteLLM HAS BEEN COMPROMISED, DO NOT UPDATE. We just discovered that LiteLLM pypi release 1.82.8. It has been compromised, it contains litellm_init.pth with base64 encoded instructions to send all the credentials it can find to remote server + self-replicate. link below

🚨counter-surveillance used to cost thousands. now it’s $20 in your pocket. someone built an open source device that detects when feds are spying on your phone. > it’s called rayhunter, a project by EFF. feds use a tech called stingrays, a fake cell towers use to track EXACT location and has the ability intercept your calls. > rayhunter detects them in real time and alerts you almost instantly, zero delay. you simply buy a cheap hotspot, flash it with open-source software, carry it in your pocket and voila. portable counter-surveillance. this used to cost thousands and requires expert knowledge but not anymore.
