Hackers have released software they say sabotages a suite of forensics
utilities Microsoft provides for free to hundreds of law enforcement agencies
across the globe.
Decaf is a light-weight application that monitors Windows systems for the
presence of COFEE, a bundle of some 150 point-and-click tools used by police to
collect digital evidence at crime scenes. When a USB stick containing the
Microsoft software is attached to a protected PC, Decaf automatically executes a
variety of countermeasures.
