Trj/KokoBizus.A is a Trojan, which although seemingly inoffensive, can actually carry out attacks and intrusions.
Trj/KokoBizus.A is designed to affect one or more specific companies.
- On remote sites: it launches denial of service attacks against Web servers or remote databases.
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 awaits remote-control orders received through
Trj/KokoBizus.A 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.
- It injects itself in running processes.
- It deletes the original file from which it was run once it is installed on the computer.
Trj/KokoBizus.A 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.
