It will ask you to login to your profile. Of course you will type in your username and password and expect to be logged in. The fake website will collect the data you put into the entry fields and then redirect you to the actual website where you will be logged in for real. The data that got recorded from you will be sent to a hacker and now the security of your profile is at risk. That is a good example of phishing, except that hackers use it to steal your bank account information by redirecting you to a fake banking website.

Beast was one of the first Trojans to feature a reverse connection (a method usually used to bypass firewall security on open ports) and once established, gave the hacker total control over the victim's machine.
Beast comes with these mods and features:
- Direct or Reverse connection option
- DLL injection location (e.g. explorer.exe)
- Server name change option
- Server installation directory (e.g.
) - Various IP and Server info notification options (e.g. email, icq, cgi, etc.)
- Startup keys selection
- Antivirus and firewall killing
- Other miscellaneous options (e.g. automatic server file deletion, fake error messages, offline keylogger, icon changer, etc.)
If you are infected with Beast, you should immediately attempt to cleanse the threat (although this may be difficult as the Trojan takes over the entire computer) or take your PC to a specialist.
