i started doing leet code and algebra questions again because I know vibe hacking is as bad as scrolling reels for me ಥ_ಥ
I’ve always been obsessed with low-level security, and I never thought I’d fall in love with detection engineering.
But here we are. I’m genuinely excited to contribute more to Sigma in the near future.
New Sigma release r2026-07-01 is available for download. @sigma_hq
🌟 20 New Rules
🛡️ 61 Rule updates
🔬 22 Rule Fixes
Explore the full release on the Sigma Phoenix platform → sigma.nasbench.dev/releases
Or if you like the GitHub view → github.com/SigmaHQ/sigma/rel…
Highlights of this release include:
- Coverage for TanStack Supply-Chain, CVE-2026-41089 and Copy Fail.
- Updates to the AV detection rules, sysinternals based rules with the inclusions of ARM variations, and more file sharing URLs added to related rules.
- Multiple FP and logic fixes targeting Azure rules as well as multiple windows rules.
And much more!
As always, a special thanks to the many contributors that helped shape this release, specifically
Andreas Hunkeler, Ajani (AJ) Jeffreys, CHIRAG-DAMANI-08, Adam Lin, Ali Nikkhah, Erik Nordström, @_ezlucky_, @frack113, Fukusuke Takahashi, Gene Kazimiarovich, Anudev, Chris Barros Henriques, Leonardo Gasparini, @pedrinazziM, Cole Munz, @cyb3rops, norbert791, @nullbyte0x, PachkaKofe04, @phantinuss, potato-20, ruppde, David Sarkisyan, @_swachchhanda_, uniqu3-us3r, Vladan Sekulic, @X__Junior, Aron Wahl, zendannyy
This is so funny. I analyzed this sample a few days ago, and this technique isn’t new, I’ve seen it in a few samples already
I guess we’re not totally ready to be vibe-reversers yet.

ذا تستخدم N8N هالتغريده تهمك
في 5 ثغرات حرجة في N8N ، كل وحدة تقول الزوود عندي وتقييماتهم 9.4 CVSS .
4 منها من نوع RCE.
وواحدة تسمح بقراءة ملفات حساسة من السيرفر، وقد تسبب اختراق كامل السيرفر.
I made a blog, I will be writing there about RE, Malware, VR. For the first post, I wrote a short breakdown of a recent bug I found in jq: CVE-2026-43896.
Hope you enjoy it ; )

زمان عن اليوتيوب,
صورت مقطع بسيط استعرضت فيه tool بسيطه اشتغلت عليها اخر اسبوعين بوقت فراغي تسوي emulation للكود بداخل Binary ninja بدون اي كتابة للكود مع تحكم جيد في المحاكاة وقدرة على انك تحاكي مع arguments
واتمنى تفيدكم.

احتجت بلوقن بسيط في CTFd وماحصلت الي في بالي عشان كذا سويته بنفسي ورفعته Github غالباً اي احد يستعمل CTFd بيحتاجه:

الحمدلله,
Finished 26th place at @CrackmesOne Reverse Engineering CTF. Had a lot of fun and enjoyed every challenge.
The competition had 1500+ players and ran for a full week.
Great learning experience, definitely planning to play the next edition!
