Brief Description | |
DNSChanger.PC is a Trojan, which although seemingly inoffensive, can actually carry out attacks and intrusions. It reduces the security level of the computer:
it changes the security settings of Internet Explorer, decreasing its security level. It uses stealth techniques to avoid being detected by the user: - It uses techniques included in its code to hide itself while it is active.
- It injects itself in running processes.
- It deletes the original file from which it was run once it is installed on the computer.
DNSChanger.PC 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.
