Ashigaru Desktop 1.5.1 is out. On Oct 28 the Tor network stopped accepting older Tor versions, so 1.5.0 can’t connect. 1.5.1 bundles Tor 0.4.9.5 and fixes it. The in-app updater needs Tor, so download manually and verify the signature: github.com/linkinparkrulz/as…

🚨Scam alert: @build_on_bob is refusing to return my Bitcoin after a failed BTC->USDT swap, despite advertising its service as NON-CUSTODIAL. "Swap reverted. Your funds are safe." Except nothing arrived to the Bitcoin refund address I provided. And then this:

this is good UX
Scan all 99 dice into your @SeedSigner in one second. The new hardware (ESP32-P4 series) -- built-in touchscreen -- much easier to read and use than the Pi Zero. You can buy a pack of 100 8mm dice from Amazon for $6, so the only constraints are waiting for them to arrive and not losing more than one. 🙂

Over the past two days, we released new versions of StartOS, StartTunnel and 100+ services to patch the security issues from eMudhra, PHP, and Node.js and others. We recommend updating ASAP.

1.44 MB bootable floppy that generates BIP39 seeds - Roll dice in the terminal - Mix in health-tested CPU noise or type real dice - No words until every bit of entropy is covered - Every seed can be verified on a second computer No OS. No network.

Nice to hear @Bitonic is adopting silent payments!
Bitcoin is minder anoniem dan veel mensen denken en de privacy van het protocol ligt ook onder vuur. @DanielMol en @cryptotakkies gaan in gesprek met Niels van Groningen, medeoprichter en CEO van @Bitonic. Hoeveel blijft er over voor de bitcoingebruiker? bnr.nl/podcast/cryptocast/60…

Holy Math.random fail... WTF
1/7 ⚠️ 漏洞分析:Qubic 官方钱包弱 Seed 漏洞,苹果客户端 1,404 钱包批量被盗事件分析 10 月 17 日 至 18 日,攻击者利用 @Qubic 官方 Web 钱包在 Apple 平台(WebKit/JavaScriptCore)用 Math.random() 生成钱包 Seed 的随机性缺陷,离线枚举全部 2^32 个可能 Seed,碰撞出 1,404 个有余额的钱包私钥,并盗走 2,939,606,531,944 QU(约 $1.3M)。 攻击发生后,Qubic 进行了保护性停机,87.1% 被盗资金冻结在链上,12.9% 进入 MEXC 并被冻结账户。官方目前已发布 Web 钱包 v4.26.4 修复(改用 crypto.getRandomValues),请相关用户及时更新。 一、受害者范围 1,404 个钱包地址,这些地址的共同点:Seed 由 Qubic 官方客户端在下述环境中生成,随机性不足: iPhone / iPad 上任意浏览器(Safari、Chrome、Firefox 等均被强制使用 WebKit 内核),2026-10-18 之前创建; MacBook / iMac 的 Safari,2026-10-18 之前创建; Qubic iOS App,2025 年 7 月之前创建; 二、漏洞根因:Math.random() 生成的密钥种子的随机性不足 Qubic 的 Seed 是 55 位小写字母串,理论空间 26^55(≈2^258),但实际安全性取决于生成它的 PRNG 的内部状态熵。

i rebuilt satoshi's 2009 bitcoin.exe byte for byte! afaik nobody has been able to perfectly recreate the executable published in 2009 from source, because we didn't know the exact build environment that was used. using opus 5.5, i reverse-engineered satoshi's build machine from the binary. it now outputs an exe with the exact same sha256 as the 2009 release!
