Brief Description | |
MSNworm.HX 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:
passwords saved by certain Windows services; keystrokes, in order to obtain information for accessing online banking services, passwords and other confidential information; email addresses. It sends the gathered information to a remote user by any available means: email, FTP, etc. - In the local network:
it generates a large amount of network activity and consumes bandwidth.
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
IRC; it changes system permissions, decreasing the security level. It uses stealth techniques to avoid being detected by the user: - It injects itself in running processes.
- It modifies system permissions in order to hide itself.
MSNworm.HX 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.
