![我的 Ubuntu 桌面是否受到攻击?](https://linux22.com/image/1136844/%E6%88%91%E7%9A%84%20Ubuntu%20%E6%A1%8C%E9%9D%A2%E6%98%AF%E5%90%A6%E5%8F%97%E5%88%B0%E6%94%BB%E5%87%BB%EF%BC%9F.png)
我目前面临着 Ubuntu(16.04) 桌面随机冻结的问题,屏幕上充满了垃圾像素。我甚至无法使用 Ctrl-Shift-F1 启动命令行。每次我都必须手动进行硬重启。这种情况发生几次后,我决定使用日志文件深入研究它,以下是我的发现
为了调试最近的故障,我尝试检查 /var/log/syslog 下的日志文件。我发现以下几行

看起来来自“ip-147-62-102-190.netblk.digicelpanama.net”的某个程序正在尝试连接到我的远程桌面服务器。我不知道这个服务器是什么,我以前从未听说过。我查看了网站“digicelpanama.net”,它指向一些我不了解的语言的网页。
我已经观察过该日志消息几次,并且该消息的时间戳与 Ubuntu 崩溃完全匹配。
我想知道
- 我的系统是否受到攻击?
- 我该怎么办呢?
- 还有其他方法可以调试崩溃吗?
我目前正在使用英特尔 Skylake i7 6700、华硕 H 170 Pro 游戏主板。
有人可以帮忙吗?
