How not to deal with a rootkit infestation
Posted: 14 Aug 2008, 23:03
Last week I noticed that odd things were happening with my work laptop, emails/web pages/directories closing and opening without intervention from me - then characters and parts of sentences appearing in the middle of my typing that were nothing to do with me either. The characters became more random as I yanked the server connection out of the back of the laptop, but it still was showing un-nerving indications of me not being in control of what was happening.
The company symantec anti-virus found nothing but Malwarebyte said that I had a Rootkit.Agent infection and also another nasty that I managed to destroy quite quickly. The rootkit beast took two days to finally pin down and delete as it kept re-appearing after a re-boot. The system we have refused to let me restart in safe mode, every time I put in my password the damn thing promptly returned to normal mode and re-infested itself.
While Malwarebyte at least spotted the infestation, the following were useless at best and made the matter worse in two instances.
Blacklight and Threatfire spotted nothing, neither did PC Tools Spyware Doctor, but the evil bar stewards proved to be Noadware - which loaded a Trojan of it's own but at least spotted one of the other problems, and Spy Emergency 2008 - may their authors rot in Hades. The latter piece of toxic waste tried to load half a dozen nasties but spybot spotted them and allowed me to abort the loading.
It now seems I have got rid of the problem, but tomorrow I will have the acid test of reconnecting to the server and outside world. I am also likely to have an exchange of words with our IT guy who insists that the only way the beast got in was through me opening a spam email and following a link to the source of the infestation. This is the same guy who will do nothing about the volume of spam we are receiving in case it eliminates an email from a client by mistake. This means that I am getting 30-40 nasties a day and some staff are getting over 100.
Now while I can't guarantee to have always avoided opening a spam email, I have never been so dumb as to then follow a link in one.
Anyone know if there is any other way of getting this sort of problem, and it won't help if the answer is looking at flightsim or aviation related sites in my lunchhour!
