НАСКОЛЬКО МНЕ ИЗВЕСТНО, kjournald это не сетевая программа, а программа, которая имеет дело с журналом EXT3 (я использую EXT4 на Ubuntu 16.04). Тем не менее, при запуске sudo netstap -tapn он появляется почти 700 раз при подключении к IP, принадлежащему какой-либо компании в Италии (bladerunner.consultingweb.it).
$ sudo netstat -tapn | grep 195.128.235.204

Я действительно этого не понимаю. В kjournald не похоже на какой-то подделанный исполняемый файл, а на какой-то внутренний инструмент, поэтому я не уверен, как это сделать:
$ cat /proc/20086/cmdline
[kjournald]
Я попытался nmaping и telnetвходил в порт, но не мог понять, что он делал:
$ telnet 195.128.235.204 2525

Как и предполагалось, это было результатом взлома. Полное вскрытие может быть найдено на GitHubвместе со всеми сценариями и тем, как я узнал.
