Approaches for transferring control to a bit set. Execution of a bit set upon a host operating system is monitored. A determination is made that the execution of the bit set exhibits a suspicious characteristic. In response, the execution of the bit set on the host operating system is ceased. Then, the bit set is copied into an isolated environment and control to the bit set is transferred within the isolated environment. Thereafter, execution analysis upon the bit set is initiated in the isolated environment. The isolated environment may, but need not, reside on a different physical device than upon which executes the host operating system.
