To thwart hackers, firms salting their servers with fake data
The Waseca, Minn., company began planting fake data in Web servers to lure hackers into “rabbit holes” in the hopes of frustrating them into giving up. The bait was varied — including bogus user log-ins and passwords and phony system configuration files. Anyone who took it was being watched by Brown, their computer locations tagged and their tactics recorded.

In the parlance of network security, digital deception is known as a type of “active defense,” a controversial and sometimes ill-defined approach that could include techniques as aggressive as knocking a server offline. U.S. officials and many security experts caution companies against taking certain steps, such as reaching into a person’s computer to delete stolen data or shutting down third-party servers.
Those actions probably would violate federal law, FBI officials said. The bureau also warns that the use of deceptive tactics could backfire — hackers who identify data as bogus may be all the more determined to target the company trying to con them.
