|ululul is a worm with the characteristics of a Trojan. |
ululul spreads by copying itself, without infecting other files. Its main objective is to collapse computers and networks, preventing users from working with their computers.
Furthermore, due to its Trojan characteristics, ululul allows hackers to get into and carry out dangerous actions in affected computers, such as capturing screenshots, stealing personal data, etc.
ululul prevents access from programs to websites of several companies related with security tools (antivirus programs, firewalls, etc.).
ululul redirects attempts to access web pages of certain banks to spoofed pages, with the aim of logging information entered by the user in these pages.
ululul redirects attempts to access several web pages to a specific IP address.
ululul 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.
- Peer-to-peer (P2P) file sharing programs: it makes copies of itself with enticing names in shared folders belonging to these programs. Other users of this type of networks then voluntarily download and run the infected files.
- 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.
