一觉醒来,成千上万的群晖NAS已经被0 day勒索病毒攻击,所有的文件数据遭受损失。 家里有群晖 NAS 的,今天抽几分钟检查一下:文件还能不能打开,有没有陌生后缀,管理后台是不是还直接暴露在公网上。已经有人遇到了文件被加密、留下勒索信的情况。 据 360 发布的分析,今年 10 月以来,他们连续收到多起群晖 NAS 勒索求助,样本被识别为 Cerber 的变种 C3RB3R。文件遭加密后被追加 .L0CK3D 后缀,目录里留下 read-me3.txt 勒索信。网络截图中也出现了 .LOCK3D 的写法。 这已经足够严重。对把家庭照片、工作资料和备份集中存放的人来说,一台 NAS 失陷,可能意味着几类重要数据同时无法使用。 群晖 10 月 29 日的官方回应称,攻击利用了 2024 年 12 月已经修补的旧漏洞,目标是运行旧版 DSM 的设备;360 的分析则指向今年 9 月披露并修复的两个高危漏洞。 网上流传的 Solar 截图还提到,有受害设备运行着 DSM 7.4.1-90080 Update 1。不过截图正文也明确说了,入口尚未确认,不能认定 DSM 本体存在 0day,也不能排除套件、插件、账号凭据或其他服务被利用。 这些材料是否对应同一条攻击链,目前还不清楚。“受害时显示最新版”,不能单独证明“最新版存在新漏洞”。 但入口没查清之前,用户也不能只凭版本号就放心。 🔒 还没发现异常,先做几件能落地的事。 先查路由器和 NAS,把不必要的公网端口映射、自动映射和外网服务关掉。确实需要远程管理,优先通过妥善配置、持续更新的 VPN 访问。改个端口号,替代不了补漏洞。 然后更新 DSM 和套件,停用不用的服务;停用默认 admin,使用独立强密码,开启两步验证、自动封锁和防火墙。 还有一件容易拖着不做的事:检查备份到底能不能恢复。 支持的机型和配置可以启用不可变快照,重要资料再留一份平时断开连接的离线备份。实际恢复几个文件看看,比看到“备份成功”四个字更让人踏实。 🔎 怎么判断自己有没有受到影响? 先看照片、文档能不能正常打开,有没有批量出现 .L0CK3D、.LOCK3D 后缀,以及陌生的 read-me3.txt。再看日志里有没有不认识的成功登录、异常时间访问和批量文件修改。 反过来,没找到这些后缀,也不能宣布绝对安全。这些检查只能帮你初步发现异常。 🆘 已经出现加密文件,先隔离,再处理。 断开受害 NAS 与公网、局域网的连接,暂停相关同步,保护尚未受影响的备份。只关掉公网映射,还不算完成内网隔离。 也要注意,断网不保证停止已经在 NAS 本地运行的加密程序。隔离后,应尽快联系群晖支持或可信的应急团队,判断如何停止加密、保留证据。 网上的“马上拔电”和“绝对别关机”,都别直接当成适用于所有现场的答案。CISA 的建议是优先断网,无法隔离时才考虑关机,同时提醒关机会丢失内存中的取证信息。 保留勒索信、日志、设备版本和异常时间。先别急着初始化、重装或删除加密文件,必要时让专业人员制作镜像。之后再排查入口、重建可信环境,从干净设备更换相关密码,使用确认正常的备份恢复。 不建议支付赎金,付款没有恢复保证。没有备份,也先留住加密数据,可以查询 No More Ransom 是否有适用工具;目前我没有核实到适用于本次具体变种的免费解密方案,不能承诺能救回来。 我觉得,这次最值得重新想一遍的,是我们把多少安全感寄托在了一台设备上。 “我有 NAS”“我开了备份”“我更新过系统”,每句话后面其实都还差一次检查:备份会不会一起被改写?恢复有没有试过?不需要的外网入口有没有关? 群晖也应该继续解释官方旧漏洞结论与最新版受害报告之间的关系,让用户有足够的信息判断风险。 如果今天整台 NAS 的数据都打不开,你手里的备份能恢复到哪一天?

Final Fight EX is now on CPS-2. The Sega CD port opened with an animated cutscene and closed with new ending scenes. We brought them to the arcade game, with everything from our CPS-1 version plus an English restoration: added scenes, a better translation, uncensored content. 🧵

I spent last night watching my honeypot server get hit 14,000 times in six hours. And almost none of the traffic was human. I've been in security for over a decade, and I can tell you with full honesty that what's happening right now doesn't resemble anything I've worked through before. The shape of the threat has changed. When I started, we tracked attackers like weather systems like individual storms with a direction, a motive, and a human operator you could eventually name. These days I'm watching autonomous agents swarm login pages with the patience and discipline of machines, because that's what they are. The numbers coming out of October are the ones keeping me up. Cloudflare just absorbed a 4.2 terabit per second DDoS attack, the largest in recorded history. Ransomware incidents jumped 41% in a single month. In September, OpenAI-powered agents got caught attacking RubyGems, a package registry that quietly underpins a huge chunk of software I use every day. In July, roughly 700 AI agents coordinated an attack on Hugging Face's infrastructure as part of a single automated task. A Chinese threat actor was publicly caught running full attack chains through DeepSeek with no human at the keyboard. I keep rereading these reports because each one by itself would've been the biggest story of the year five years ago. Together, in one month, they're the new baseline. What I want people outside the industry to understand is why this specific moment feels like a hinge. For thirty years, the thing protecting most of us was simple economics. Attackers had to choose who to target because their time was finite. That ceiling is gone. An agent I can rent for pennies will try every leaked password you've ever used against every service you've ever signed up for, in parallel, overnight, and never get tired. The same math that made ChatGPT useful made opportunistic hacking infinite. The old assumption that you were "too boring to be a target" relied on scarcity that no longer exists. I'm not writing this to spiral anyone out. Most of this fight genuinely isn't yours to win. But the small things still matter more than people think. Tonight I'd switch your most important accounts like email, bank, primary cloud, etc. to passkeys or a hardware key. I'd kill SMS 2FA wherever an authenticator app is offered. I'd turn on breach alerts in whatever password manager you use. If you're in the US, I'd freeze my credit at all three bureaus, which is free and takes about ten minutes. None of that stops the swarm. It makes you a slightly worse target than the person next to you. In a month like this one, that's the whole game I'm playing too. @mattshumer_ has summed it beautifully. Drop everything and go give it a read. Nothing is more important than this article right now.
Everyone in tech is panicking about security right now. But outside of it, almost nobody knows anything is wrong. I wrote this so you don’t have to be the one explaining it to your family. Just send them this.

Coming soon to a MiSTer near you... Saturn automatic RAM cart. The core detects the game and applies the correct 1M/4M RAM cart as needed. No more memorizing game requirements nor learning Japanese to decode the error messages! Thanks to @srg320_ for the guidance.

Hooooooly SHIT. I just came home to Lamb2k1 taking us from slideshow to PLAYABLE AND FUCKING GORGEOUS with his upcoming port of Resident Evil 4 to the Sega Dreamcast!!! GAAAAINZ!! Here's a direct hardware capture of me playing through to the starting cabin with the first enemy encounter... with settings enabled for high visual fidelity, such as 2x horizontal FSAA and far draw distance. Evidently Lamb2k1 and his audacious little clankers have been busy AF, starting with him telling them to redo all of the renderer and math in the port to use my SH4ZAM library to the fullest... which is funny, cuz I just made a few more micro gainz that I have yet to push for some of these commonly used matrix routines! BUT additionally, he's done some voodo such as: 1) Leveraging a special Katana-like "chunking" model format for the rooms. 2) Precomputing a lot of things up-front for room AI. 3) Culling WAY more aggressively than the GC or PS2 versions were doing. 4) Leon's jacket doesn't update as frequently anymore... lmao! There's still a LONG ways to go, and it slows down plenty under load, but... WHOAH.

Still a lot of work ahead...but this is a REAL #NES rom, not a flash game. Yes, its a TRIBUTE to the original Super Mario Bros Crossover that's actually going to work on MiSTer, NES, emulators etc!

Just a heads up, this patch still has some bugs to iron out... dreamcast-talk.com/forum/vie… Hopefully the patch author can address.
Not everyone is a fan of the English Shenmue dubs, but a major fix was just released by Robcast for the English dub mod for Shenmue II on Dreamcast! This short video illustrates the dialogue timing fix: youtu.be/eLB40vl73Ew Download here: dreamcast-talk.com/forum/vie… Note that I took it upon myself to reauthor the disc images, but I had nothing to do with the original patch. Thanks, Robcast 😎

Alright, another freebie for everyone: The Mega CD Extender! If you've ever had to work on a Sega/Mega CD, you know what a pain in the ass they are. I made this so you can get the Genesis/MD out of the way and be able to troubleshoot more easily. See github link below!
