A Race Within A Race: Exploiting CVE-2025-38617 in Linux Packet Sockets
#CVE-2025-38617 is a use-after-free vulnerability in the Linux kernel’s packet socket subsystem, caused by a race condition between packet_set_ring() and packet_notifier(). The bug has existed since Linux 2.6.12 (2005) and was fixed in kernel version 6.16. It allows an unprivileged local attacker — needing only CAP_NET_RAW, obtainable through user namespaces — to achieve full privilege escalation and container escape.

Analysis of BlueHammer: LPE Exploiting Windows Defender Updates
BlueHammer is dangerous not because it uses a simple bug, but because it chains together several legitimate Windows components in a clever and unexpected way. It tricks trusted features into exposing sensitive system information without relying on obvious malware behavior. Specifically, the exploit abuses Windows Defender’s signature update mechanism, the Volume Shadow Copy Service (VSS), the Cloud Files API, and a Time-of-Check to Time-of-Use (TOCTOU) race condition to read the system's SAM database.

طنز عجیبی است که گویا حتی ارتش آمریکا با هالیوود مسموم شده است جوری که همه این مشاوران و تکنیسینها و وابستگان نظامی به فردایی فکر میکنند که قصهشان را کتاب یا فیلمنامه کنند.
اما دنیای واقعی از سینمای آمریکا عبور کرده و به این Top Gun و نجات سرجوخه رایان میخندد.
وظیفه تاکر کارلسون که لفاظیهای زشت ترامپ را محکوم کرد، ۴۸ نماینده کنگره که طرح استیضاح او را آماده کرده بودند و مجموعه بزرگی از ژورنالیستها و شخصیتهای آمریکایی که تهدید ضدتمدنی او را محکوم کردند، همه این بود که «راه خروجی آبرومندانه» برای ترامپ فراهم کنند. جوری که انگار او واقعا توان نابودی یک شبه ایران را داشته و تحت فشار اطرافیان کوتاه آمده است.
واقعیت این است که ایالات متحده اگر میتوانست بدون یک لحظه دغدغهی جنایت جنگی ایران را نابود میکرد اما آمریکا در آخرین لبه بضاعت نظامی، اقتصادی و روایتسازی خود ایستاده است. سوال بزرگ اندیشکدهها از این پس این خواهد بود: «از بین ایران، چین و روسیه، تنها ایران، غیر اتمی بود و نتیجه به اینجا رسید. آمریکا با چین چه خواهد کرد؟»
طی ماههای آینده در دنیای اقتصاد و مناسبات تعیین کننده نظم جهانی، وضعیت افتضاح آمریکا حتی برای افراطیترین دوستداران ایالات متحده مفهوم خواهد شد.
از یک نظر میتوان گفت این نفرین نیکولاس مادورو بود که با تسلیم خود ترامپ را به هوس انداخت تا احتیاط را کنار بگذارد، به گرداب هرمز کشیده شود و به نحوی جبرانناپذیر تحقیر گردد. ونزوئلا گرانترین پیروزی مفت و مجانی تاریخ آمریکا لقب خواهد گرفت.

Lost over 400 followers on social media after I made a comment about the President of the United States and his posts on Truth Social
The leader of a country (literally any country) writing "open the fuckin' strait, you crazy bastards, or you'll all be living in Hell" and "Praise be to Allah" when living in a predominantly Christian nation, on Easter Sunday, is genuinely hysterical.
Like, imagine if Claudia Sheinbaum said that, or if Volodymyr Zelenskyy said that
It made me audibly laugh out loud. I'm still laughing about it.

Hypervisor-Based Defense (Windows Kernel Protection)
Original text by Ido Veltzman
The article “Hypervisor-Based Defense” discusses how hypervisors can be used as a powerful defensive layer to protect Windows systems from kernel-level attacks. The author explains that modern attackers frequently target the kernel using techniques such as Bring Your Own Vulnerable Driver (BYOVD) or malicious kernel modules that bypass traditional security…

The Register :
During the presentation, Stanley displayed a map of the middle east in Maven that showed dozens of cartographic icons in Iran marked in red, some designated “HQ.” One of the marks was positioned on an area of the map that corresponds to Minab, where a missle struck a girls' school near a military target, killing more than 160 people.
