Optimizing DX12 on VMPal.com. The benchmark is now around NVIDIA 5080? There's still plenty of room to improve performance (about 20–30% up).

皆様に、今夜に対応して頂きたい大至急のお願いです。   多くのウェブサイトで使用されているPHPに関し、PHPのセキュリティチームが、重大な2件の脆弱性に関する注意喚起を行っています。   公開しているウェブサイトでPHPを使用しているか確認し、今夜、10月21日午後11時(日本時間)に公開される修正パッチについて、可及的速やかに適用できるよう準備をお願いします。   修正パッチを速やかに適用することが困難な場合は、例えばウェブサイト等を一時的に停止させることも、リスクを低減させるための有効策の一つと考えられます。   国家サイバー統括室のXアカウントでも関係する情報を発信していますので、そちらも参考にして下さい。 国家サイバー統括室(注意・警戒情報)(@cyber_forecast) / X

🚨 PHP2Shell detection is now available in Burp Suite Professional & Burp Suite DAST. Most of the web is powered by PHP, which means most of the web is vulnerable to these critical unauthenticated remote code execution flaws (CVE-2026-109618 / 109619). You can already detect it in Burp Suite using: 🟧 ActiveScan++ v2.0.13 (portswigger.net/bappstore/31…) 🟧 Bambda scan checks (github.com/PortSwigger/bambd…) 🟧 BChecks (github.com/PortSwigger/bchec…) Start scanning for the vulnerability now → portswigger.net/bappstore/31…

🦛🦛🦛Microsoft patched PetitPotam this October: EFSR now only resolves local paths. This means WebDAV to LDAP Coercion is fixed! Remaining methods for clients are WSP (coercing SMB) and PrinterBug (coercing RPC), but both cannot be relayed to LDAP 💀💀💀

I thought the first rule of EDR Reversing Club was you don’t talk about EDR Reversing Club. xitter.cf/OffensiveAIcon/status/…
Your EDR Has Boundary Issues. @harmj0y and @tifkin_ of @SpecterOps explore how adversarial machine learning can evade EDR detection- and how LLMs are accelerating the reverse engineering behind it.

Song Xingyu, a self-taught Gen Z vlogger from Badong in China's Hubei province who posts as Shenqi Ayu, has built a rideable hoverboard inspired by the Green Goblin's glider in Spider-Man and flown it across the Yangtze River. After his first five-turbojet prototype caught fire, he rebuilt it around ten brushless electric units with more than 30 kg of thrust each, and trained on it with an AI posture coach made from two phones.

🕵️‍♂️ Pivot From Targeted Industries to Actor Infrastructure Do you know which threat actors are targeting the sector you care about? We can help with that. On our platform, you can filter the threat actor dataset by sector, open a matching profile, and review the activity tied to that actor. In this example, we start with Information Technology, narrow the list to actors tied to that sector, and land on WageMole, a North Korean state-sponsored group. From there, we can pivot into its IPs, hosts, SHA256s, and related activity. See which actors are targeting your sector 👉 hunt.io/get-started #ThreatHunting #ThreatIntel #CyberSecurity

1/ Introducing the Cua Spaces SDK. Every big lab now ships a bot with its own computer: Grok Bot, Muse, dots. None let you bring your own. With Cua Spaces, now you can. Put Claude Code, Codex or any agent on compute you choose, and run jobs across all your computers at once.
