Sohanat.Y 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 affects productivity, preventing tasks from being carried out: - In the affected computer:
it converts the computer into a platform for taking malicious action surreptitiously: spam sending, launch of Denial of Service attacks, malware distribution, etc.
It reduces the security level of the computer:
it changes the security settings of Internet Explorer, decreasing its security level; it changes system permissions, decreasing the security level. Sohanat.Y 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 uses techniques included in its code to hide itself while it is active.
Sohanat.Y 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.
- Instant messaging: it sends links pointing to a copy of itself to all users included in the infected user's contacts list.
- Computer networks (mapped drives): it creates copies of itself in mapped drives.
