| Category Description: |
Trojans are malicious applications that pose themselves as legitimate software in order to trick users to install them. Once on the victim's machine, it may run any number of malicious process to steal vital information or inflict damage to other software. |
| Official Description: |
Surferbar is an Internet Explorer toolbar that might be associated with a new version of a trojan horse program called AFlooder. It appears to be an ActiveX drive-by download. Isets your homepage to their website along with displaying popup ads. |
| Comment: |
- The old homepage at surferbar.com seems to have died.
- The new AFlooder variant is an irc trojan/spybot that uses worm techniques to spread to machines via web pages. It is apparently coded to have qualities of remote access trojans, IRC bots, keyloggers, and even seems to have the capability to carry out DDoS attacks if the owner orders it to. It uses an exploit to write and execute its' injector program to machines without the user's acceptance or knowledge, then it uses NTFS's alternate file streams to hide itself where there's very little chance of finding it -- in the actual windows folder system32. |
