PWS:Win32/Fareit is a family of trojans that steals sensitive information from the affected user's computer and sends it to a remote attacker.
Installation
PWS:Win32/Fareit is usually installed to a particular location by other malware, and runs from this location.
For example, Backdoor:Win32/Cycbot installs it to %ProgramFiles%/lp/<four hexadecimal digits>/<number>.tmp (for example, %ProgramFiles%\lp\008a\7.tmp), while Rogue:Win32/FakeScanti installs it to %AppData%\dwme.exe and %temp%\dwme.exe, or %AppData%\svhostu.exe and %temp%\svhostu.exe.
When run, it creates a registry entry such as the following:
In subkey: HKCU\Software\WinRAR
Sets value: "HWID"
With data: <guid> (for example, {FF72229E-611D-4FD5-A025-00C933DAA429})
It may also store information under the registry value HKCU\Software\WinRAR\Client Hash, or in the following file:
%temp%\Client Hash
Some variants delete themselves once they have finished running.
