Autorun.JXL is a worm that spreads by copying itself, without infecting other files.
It affects productivity, preventing tasks from being carried out:
- In the affected computer:
- In the local network:
it generates a large amount of network activity and consumes bandwidth.
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 modifies system permissions in order to hide itself.
It uses several methods in order to avoid detection by antivirus companies:
- It prevents scanning tools from running, such as Windows Registry Editor, FileMonitor, etc.
- It terminates its own execution if it detects that a debugging program is active.
Autorun.JXL 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.
- Email: sending emails that include a copy of itself as an attachment. The computer is infected when the attachment is run.
- Computer networks (mapped drives): it creates copies of itself in mapped drives.
- File infection: it infects different types of files, which are then distributed through any of the usual means: floppy disks, email messages with attachments, Internet download, files transferred via FTP, IRC channels, P2P file sharing networks, etc.
