It used the typical client–server model where the client would be under operation by the attacker and the server is what would infect the victim.  Beast was one of the first trojans to feature a reverse connection to its victims, and once established it gave the attacker complete control over the infected computer.  The virus would be harmless until opened.  When opened, the virus would use the code injection method to inject itself into other applications.
