- a user that obviously don't know killall command
It's small hours in Europe... Very tired...gerard82 wrote:miroR,
Why don't you check /var/log/auth.log?
It should tell you whether anyone but you logged in.
I have no idea what happened but the change that someone got in soooo remote.

You must get scared a lot. In my experience, it's impossible to have an internet-facing ssh server that doesn't get the living crap bombarded out of it by unsolicited login attempts.krinn wrote:I'm not security expert, so i might be wrong, but honestly, an ssh log with script kiddy attempt would scare me more than your video
Well, the attacker could have used those stacks and heaps and whatnot that hardened Gentoo discusses...gerard82 wrote:miroR,

Some of the best reads I had in recent months:miroR wrote:...[snip]...
It is likely, it is rather probable that I do have the previous content, the deleted (what else?) content of the auth.log. It depends on the space of time that the attacker did his shameful work though... If he watched for sufficiently long time (say using some of those rootkits that the SELinux and the whole of LSM provide the shameful people hooks for, having NSA in mind only the stupid interest of theirs to spy on people, on any individuals at their will, and the question arises who have the Linux kernel people become if they agreed on the scheme?... see why I am so much against LSM and SELinux?... pls. find about rootkits on SELinux and LSM from say wikipedia, anyone who thinks I am talking nonsense here!)...
(Pertaining to the above digression, the rootkit used against me doesn't necessarily have to do anything with LSM, because I was on vanilla kernel before. Just using this space to raise awareness on what danger is there with our Linux... Let it not be turned into an appliance like any mobile phone of today, that can be listened to by spy people by default! Let's defend the freedom of our Gnu Linux!)
...[snip]...
I guess you won't deny there's no SELinux, no AppArmor etc. without LSM.Ant P. wrote:How did some 1990s JavaScript popup spam turn into this conspiracy theory about SELinux?
I did.Jimini wrote:I had some difficulties to figure out the problem between the smalltalk here - but to cut a long story short: I experienced a similar behavior of konqueror some time ago. When I opened the program, it kept opening new windows without end. I Solved it by installing dolphin (konqueror seems to depend on that package in some way). You may also take a look at https://bugs.kde.org/show_bug.cgi?id=242970 .
Sure useful. Thank you!Jimini wrote:I hope this helps, if not, I apologize for not reading the whole bunch of postings in this thread.

I am still amazed how:Code: Select all
... how they land SELinux on unsuspecting users as if it wasn't surveillance-ready, which it is, just like Windoze or Mac and things.
This is my big complaint with Gentoo, which I otherwise like very much.
The good one is, in my opinion, grsecurity. Not SELinux!
