Lately there has been a very serious, new type rootkit virus spreading in various routes, and one very serious way for LJ users is the video spam comment. Some users have recently been receiving comments with youtube links (embedded videos) - some are just spam comments with a link in the comment, some are made by hijacked accounts and even include text to make the comment seem real (for example telling you your video has been stolen and provides you with a youtube link).
These youtube links are infected with rootkit that will infiltrate your computer and steal personal information and possibly hijack the Internet connection. So members, please be VERY careful with any youtube links in comments! This virus is new and nasty, so we don't know how serious it can end up being on the computer.
One of our mods, kira_shadow, fell victim to this rootkit because a hijacked account made a proper comment with a link to a so-called "stolen video" and her computer is being treated at a shop right now, but there is no telling how serious it will end up being. In some cases Internet connection providers have been shutting down connections (at least here in Finland) when computers have been infected with the rootkit. (One of my sister's friends still haven't gotten her connection back, we got ours back after I rebooted my mother's infected laptop.) Please note that I don't know any details since this this particular case has not happened to me, I'm only reporting what kira_shadow knows of the issue that happened to her.
So please be very careful! Also, kira_shadow is currently not really available for mod duties until she gets her computer back, so please do not contact her about mod related business for a while, or at least don't expect her to be able to answer soon as we don't know how long fixing her computer will take. (On a somewhat related matter, I'm leaving to Japan for a month next week, and yararanger is there atm as well with limited Internet access, so we are not really too available either ^^;)
EDIT: At the moment it seems kira_shadow's computer wasn't affected with the worst possible virus (at least apparently?) so it could be that the virus hidden in the video is something less severe than the torpig/mebroot rootkit that has been causing serious issues lately. Nevertheless, please be cautious of these kind of spam links for your safety.
Just wanted to let you all know about this.
