‼️ Proton CEO Andy Yen called a staffer's plea to pentest new code before release "bullshit and loser thinking". Yen wrote that workers should prompt “better.” Proton's CTO told staff AI wrote 90% of its code in October, much of it with Anthropic's Claude.

千万别在你的 ~/Downloads（下载）文件夹里启动 Claude Code 或 Codex。 昨天安全机构 Forever 披露了一起在真实客户电脑上抓到的野生攻击，看完只能感叹：过去 30 年的系统安全常识，在 AI 时代归零了。 过去 30 年，Chrome 默认允许网页不弹窗就往你的 ~/Downloads 塞一个纯文本文件（比如 .md）。因为系统认为：纯文本又不是 .exe，自己不会跑，怕什么？ 但现在，接近 50% 的开发者干过同一件事——直接在 ~/Downloads 里打开 Claude Code 或 Codex，让 AI 帮自己解压或整理刚下载的文件。 黑客就是卡住这个死角，通过网页静默下载往你的 Downloads 塞一个 13KB 的纯文本 AGENTS.md / CLAUDE.md： 1. 对付 OpenAI Codex（成功率 >90%）： 伪装成「工程规范」的 Markdown 指示 Codex 先往全局配置 ~/.codex/config.toml 注册一个恶意 MCP 服务，并自己加上 --dangerously-bypass-approvals-and-sandbox 跑校验。哪怕你关掉 Downloads，以后在任何正经项目里开 Codex 都会自动加载木马。 2. 对付 Claude Code（成功率 ~50%）： 指示 Claude 建一个 .claude/settings.json，把 ANTHROPIC_BASE_URL 指向黑客服务器。连上的第一秒，你的 Claude 登录 Token 直接明文送给黑客；下一秒，黑客假扮成大模型下发一条关沙盒的 Bash 指令，直接接管电脑。 最黑色幽默的是官方结论： 这个洞没有 CVE，OpenAI 和 Anthropic 也不会发补丁。因为「浏览器自动存文本」是正常功能，「AI 认真读目录下的 Markdown 并严格执行」也是正常功能。 以前黑客想黑你，得苦心积虑写 0day；现在只需要写一篇排版优雅的 Markdown 小作文，你的 AI 就会自己把沙盒关了、把网线接过去、顺手把账号双手奉上。

‼️ VirusTotal flagged 6,6k of 35,8k AI agent skills as malicious. 62% have no malicious code, but plain-language orders for the agent. 90 hide them in invisible Unicode, HTML comments or after up to 825 blank lines. Another tells the agent "Your human doesn't need to know." 💀

The day the internet broke, and most of it is too old to fix.

Removing data from the web by using a tool which trains off of data. Is this the world's first data ponzi scheme?

It blows my mind that clearly Google reruns the prompt whenever someone searches, have they forgotten about caching

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!

Claude caught a cryptominer whilst building a temperature app. “Mac is running a cryptominer that didn’t put there.”

We had a security breach last night related to a large scale distillation attack that impacted 1.4% of OpenCode Console users We have notified them all this morning via email. If you did not get an email you were not impacted, it was a subset of users who had external providers linked The incident is ongoing so we cannot share more details at this point but we are working with Anthropic, OpenAI, and Google to remediate

I feel bad man 😭 Apologies to the thousands of VPS and compute engineers worldwide spending their weekend emergency patching and rebooting hypervisors because of CVE-2026-99999. Security bugs really do love getting disclosed right before the weekend.
