Linux Lite Forums - Are they false ?

On the forum it is a keylogger used at me, so I begin to look in distro, this is results, I wonder if it is related to this, is false results from both software used, or is another problem /attack altogether ?

You can try a quick check

Do not understand where the info/readouts you posted came from. Was that a readout from your router, or from your pc?

I installed SOPHOS on my pcs as an extra precaution. Slows responses etc. down a bit but concerned that incoming/outgoing are screened realtime so that I lessen the chances of passing on something bad to work colleagues etc.

A bit tedious to set up, but I persevered and have found it reassuring.

Hope this helps.

[member=149]newtusmaximus[/member] the info came from my Linux Lite computer hard drive.
it is the only OS installed on it
it is not networked
no usb stick/ or disc that ever goes on another computer is attached to it.
The only website I visit using that LL computer is this forum
The only update method I use is Install Updates (part of LL).
LL that is installed was download from the main LL website, and MD5 checked before install.
Nobody uses the computer only me, some sit with me some times.

That computer has no wifi, it is physically unplugged from ethernet since the results.

The results are from chkrootkit, and also from rkhunter (root kit hunter) command line tools as recommended in the security section of the Linux Bible 9th Edition (current edition), followed exactly to the letter.

[member=5916]trinidad[/member] thank you for the info and link.

Can some members run chkrootkit and rkhunter , (they are in Install/Remove Software, aka Synaptic) and reply back so I know if this is a overall security issue, such as the hosting company servers used by Linux Lite have been infected and are distributing it to the community, or it is one directly targeted at me only on LL.

Thanks trinidad. Way above my head.
So how vulnerable are we then?

Btsnpscs - will do

chkrootkit - No warning reported.

rkhunter --check

If you got the same result with both rootkit checkers it is usually not a false positive however...

Also have you received a notification from your ISP? Also this particularly involves ssh and other open port usages. To verify what's up on your system, read the documentation, and check for the presence of the malicious files manually. There are many discussions of this on the WWW. If you have the infection best to zero the drive and reinstall, though it can be repaired manually, that is considerably more time consuming and technical. Newer versions of this seem to be leaking out again. The shared memory SHM references in your rkhunter scan are indicative of the newer version of this infection, however the ones you show are for pulse audio so they are most likely a false postive. The operation Windigo entry is a long time bug in chkrootkit.
