Brontok.AI is a worm that spreads by copying itself, without infecting other files.
It captures certain information entered or saved by the user, with the corresponding threat to privacy:
It sends the gathered information to a remote user by any available means: email, FTP, etc.
It reduces the security level of the computer:
it changes the security settings of Internet Explorer, decreasing its security level; it opens one or more ports to allow remote access to the computer and takes action that compromises user confidentiality.
It uses stealth techniques to avoid being detected by the user:
- It modifies system permissions in order to hide itself.
Brontok.AI does not spread automatically using its own means. It needs an attacking user's intervention in order to reach the affected computer. The means of transmission used include, among others, floppy disks, CD-ROMs, email messages with attached files, Internet downloads, FTP, IRC channels, peer-to-peer (P2P) file sharing networks, etc.
