A MAJOR HTTPS COMPROMISE eMudhra TLS intermediate certificates were found to be compromisable because they didn't bother to use random numbers. Web browsers rely on TLS certificates for HTTPS traffic. Your web browser needs the intermediate certificate to verify that, when you connect to a domain, it's real and not someone spoofing it along the TCP/IP route from your computer, Wi-Fi, ISP, to the web server. Intermediaries are trusted parties who are given the private keys to issue TLS certificates for domains. If the certificate key is compromised, anyone can issue a fake TLS certificate, tap the traffic, and listen to your Internet traffic because it is no longer end-to-end encrypted. A malicious party can read your passwords, messages, and all your online life. For example, eMudhra, with its intermediary keys, can give a "facebook.com" domain certificate for anyone, and after this, the party can wiretap your Facebook traffic. eMudhra is India’s largest Certifying Authority, employs about 600-850 staff and generates roughly $70M in annual revenue. Its main lines are enterprise identity and cybersecurity platforms, digital signature and trust services, and related consulting. Each certificate's private key was a random number between 1 and 256. Yes 256. Not 256 bits but two hundred fifty. Modern web browsers follow revocation lists and automatically stop trusting anything signed by eMudhra. But web browsers are only one part of Internet-connected software. Operating systems, development libraries, Internet of Things devices and generally anything with an Internet connection are all affected, unless its auto-updating authority has issued an emergency fix.

Can the EU and legislators fucking stop trying to kill the internet and gaming in the pretext of "protecting kids" just cause parents cannot be arsed to monitor their children themselves?
We just can't catch a break, can we? The EU Kids Act is nightmare fuel, if you look beneath the honorable surface claim of "protecting kids online". The breakdown: youtube.com/watch?v=mQRcK9nY… #StopKillingGames #StopKillingTheInternet

Why do most of the non western vrchat video players use the unity backend by default, its so limited in what it supports, why not just have avpro as the default?

Everyone in the comments saying to use CurseForge is seemingly unaware that malware is very easy to put inside a mod and get verified, seen a few payload grabber mods so far and they weren't even trying to hide it to anyone who bothered to take the smallest look inside the jar.
More than 116,000 Minecraft players have reportedly been infected by malware hidden inside fake mods and cheats since January 2026. The malware, known as WeedHack, spreads through fake download sites, YouTube videos, and manipulated search results that trick players into installing infected files instead of legitimate Minecraft content. According to security researchers, the malware can: - Steal passwords and account credentials - Collect personal and system information - Take screenshots of a victim’s device - Give attackers remote access to infected computers - Allow webcam monitoring and keylogging through paid plans What makes the campaign particularly alarming is its low cost. For around $5 per month, cybercriminals can subscribe to the service and gain access to spying and surveillance features.

PSA: @TencentGlobal is aggressively scraping the Internet to build yet another AI slop chatbot, DDoSing many websites in the process. We've found that, as of last week, their scraping bots can now solve Cloudflare challenges and behave like real users while ignoring robots.txt. In the last 24 hours alone, our website received more than 3 million successful requests from Tencent bot IP addresses, plus another 1 million that were blocked by Cloudflare challenges. These recurring DDoS attacks from Tencent have been going on for over a year, and we have been constantly adjusting our firewall rules to filter them while trying not to impact Tencent's real users. Because that is no longer possible, we're now fully blocking Tencent IP addresses, starting with ASN 132203. We recommend other sysadmins do the same. Other ASNs displaying similar abusive behaviour will also be fully blocked from our services. We'd also like to thank @Cloudflare for sponsoring us with Project Alexandria as of 2025, giving our sysadmin the tools to keep RPCS3's online services running without service disruptions.

Another thing that is going to be released with next version of VRC Light Volumes, is an in-game debugger tool! You'll be able to preview every volume, voxel, and point light. Works in any world that supports VRC Light Volumes.

ご指摘の通り、公式の発表がない現時点では、いかなる主張も推測の域を出ません。しかし、技術的な観点から情報の整理を行うことは、混乱を防ぐために有用だと考えます。 BAN通知にある「クライアントの改変」に対し、外部ファイルの呼び出し(yt-dlp)よりも、プロセスの優先度や起動シーケンスに直接干渉するツール(CPUSetSetter等)の方が、EACの検知ロジックとの整合性が高いという点に着目しています。 github.com/EllyVR/VRCVideoCa… 責任についてですが、私は根拠のない噂から友人たちを守るため、技術的な知見を持つ一人のユーザーとして、自分なりに情報を整理し、個人的な分析を分享することを選びました。逆にyt-dlpが原因だと断定する側の客観的証拠はどこにあるのでしょうか。根拠なきパニックの拡散による開発者への実害に対し、誰が責任を取るのか疑問です。 yt-dlp.exeはEACのホワイトリストに含まれており、これは作者のHaxy氏 @clienthax とVRChat開発チームとの間で協議済みの事項です。またHaxy氏も述べている通り、EACは起動時に監視対象ファイルを厳格にチェックします。もし監視対象のファイルが改ざんされていれば、ゲームは起動を拒否します。yt-dlpを差し替えても通常通り起動できるという事実は、それがEACの監視対象外であることの明確な証明です。真偽を確かめたい方は、Haxy氏に直接求めていただいたり、ご自身で挙動を確認いただくことも可能です。 以上の説明が、冷静な判断の一助となれば幸いです。 ありがとうございました。
〉外部実行ファイルである yt-dlp.exe の更新は、技術的に「クライアント本体の改変」には該当しません。 これ、言い切ってるけどその根拠あるのかな VRCに直接聞く以外には言い切る事出来ないと思うんだけど聞いたのかな これで実はこれが原因でした、の場合この人は責任取ってくれるんだよね?

Thankyou for combating the misinformation :)
【デマ注意】VRCVideoCacherに関する誤情報の拡散について ​「IT知識豊富」と自称されていますが、この投稿内容は客観的な事実に基づかない「不安煽り」と「デマ」の塊です。コミュニティの混乱を防ぐため、以下の3点を技術的・法的な観点から論破します。 ​① EAC誤Ban報告の虚偽 ソースが「海外フレンド」というのは技術議論において証拠になりません。EAC(Easy Anti-Cheat)はメモリエディタやコード改ざんを検知するものであり、外部プロキシとして動作するキャッシュツールとは動作レイヤーが異なります。現在、公式なフォーラムや信頼できるソースで、このツールのみを原因とするBan報告は一件も確認されていません。 ​② 「裁判中」という悪質なデマ 「裁判中」という表現は非常に重い言葉です。具体的にどこの国の、どの裁判所で、誰が誰を訴えているのですか?もし具体的な事件番号や公式プレスリリースを提示できないのであれば、これは開発者に対する明誉毀損(めいよきそん)および業務妨害に該当する可能性があります。憶測で法的な話を捏造するのは極めて危険な行為です。 ​③ Google垢停止と電話番号紐付けの飛躍 YouTubeの動画キャッシュ行為が、即座にGoogleアカウント全体の永久停止や電話番号のブラックリスト入りに繋がるという主張は、Googleの現在の利用規約運用から見てあまりにも飛躍しすぎています。一般的なスクレイピングやAPI制限と、アカウントの完全削除を混同している時点で、IT知識の信憑性に疑問符がつきます。 ​ - - - あなたは「何も知らずに使っている人が多い」と言いますが、あなた自身が「何も確かな証拠を持たずに」噂話を拡散し、ユーザーに根拠のない恐怖を植え付けています。 ​具体的な一次ソース(公式な証拠)を提示できないのであれば、速やかにこのデマ投稿を削除し、訂正することを強く求めます。 #VRChat
