Dumaru.AJ is a worm that spreads by copying itself, without infecting other files.
It reduces the security level of the computer:
it opens one or more ports to allow remote access to the computer and takes action that compromises user confidentiality.
Dumaru.AJ prevents access from programs to websites of several companies related with security tools (antivirus programs, firewalls, etc.).
It uses stealth techniques to avoid being detected by the user:
- It uses several third-party rootkits to hide the items it introduces on the affected computer.
- It injects itself in running processes.
- It deletes the original file from which it was run once it is installed on the computer.
Dumaru.AJ 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.
