Brief Description | |
Dialer.JSF is a dialer type malware. Dialers usually try to establish phone connections with high rate numbers, significantly increasing the phone bill of the affected user. Dialer.JSF affects computers that use a modem to connect to the Internet, as the virus modifies the Dial-up network access settings. It changes the telephone number provided by the ISP (Internet Service Provider), which is a local-rate number, to a high-rate number. It captures certain information entered or saved by the user, with the corresponding threat to privacy:
. It uses several methods in order to avoid detection by antivirus companies: - It terminates its own execution if it detects that it is being executed in a virtual machine environment, such as VMWare or VirtualPC.
Dialer.JSF 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.
