Sality is a complex virus with keylogger and backdoor functionality. Once executed, the parasite installs itself to the system, checks the current time and runs a payload if hours are equal to minutes or if date is a predetermined one. Sality infects local executable files, deletes files associated with installed security-related software including various antiviruses and firewalls. Then it runs a keylogging module, which collects system and network information, records user login names and passwords, steals sensitive information stored in specific files and finally sends all this data to a predefined e-mail address. Sality can also open a back door providing the remote attacker with unauthorized access to the compromised computer.
