Spybot.AFD is a Trojan, which although seemingly inoffensive, can actually carry out attacks and intrusions.
It captures certain information entered or saved by the user, with the corresponding threat to privacy:
keystrokes, in order to obtain information for accessing online banking services, passwords and other confidential information; user's browsing habits.
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 notifies the attacker that the computer has been compromised and is ready to be used maliciously; it awaits remote-control orders received through
Spybot.AFD accesses several websites to download files, which it then runs. These can be any type of file, although they are normally malware.
It uses stealth techniques to avoid being detected by the user:
- It modifies system permissions in order to hide itself.
Spybot.AFD uses the following propagation or distribution methods:
- Exploiting vulnerabilities with the intervention of the user: exploiting vulnerabilities in file formats or applications. To exploit them successfully it needs the intervention of the user: opening files, viewing malicious web pages, reading emails, etc.
- Via Internet, exploiting remote vulnerabilities: attacking random IP addresses, in which it tries to insert a copy of itself by exploiting one or more vulnerabilities.
- Computer networks (shared resources): it creates copies of itself in shared network resources to which it has access.
