|Autorun.JCB is a virus that also has the characteristics of a worm. |
Autorun.JCB gets into a computer via e-mail, the Internet, floppy disks, etc, and it spreads by inserting its code in other files and programs. Its effects can range from simply annoying to destructive.
Furthermore, due to its worm characteristics, Autorun.JCB also spreads by sending out copies of itself. Its main objective is to collapse computers and networks, preventing users from working with the affected computer.
It captures certain information entered or saved by the user, with the corresponding threat to privacy:
passwords saved by certain Windows services.
It reduces the security level of the computer:
it terminates processes belonging to security tools, such as antivirus programs and firewalls, leaving the computer defenseless against attacks from other malware.
It uses stealth techniques to avoid being detected by the user:
- It deletes the original file from which it was run once it is installed on the computer.
- It modifies system permissions in order to hide itself.
Autorun.JCB 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.
- IRC: It sends a copy of itself to all users connected to the channel to which the infected user is connected.
- Computer networks (mapped drives): it creates copies of itself in mapped drives.
- Computer networks (shared resources): it creates copies of itself in shared network resources to which it has access.
