Brief Description | |
WinOpts.O 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:
. It sends the gathered information to a remote user by any available means: email, FTP, etc. - On remote sites: it mass mails junk mail (spam).
It reduces the security level of the computer:
it changes the security settings of Internet Explorer, decreasing its security level; it notifies the attacker that the computer has been compromised and is ready to be used maliciously. It uses stealth techniques to avoid being detected by the user: - It injects itself in running processes.
WinOpts.O 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.
