(ONLINE.WSJ) — Law-enforcement officials in the U.S. are expanding the use of tools routinely used by computer hackers to gather information on suspects, bringing the criminal wiretap into the cyber age.
Federal agencies have largely kept quiet about these capabilities,
but court documents and interviews with people involved in the programs
provide new details about the hacking tools, including spyware delivered
to computers and phones through email or Web links—techniques more
commonly associated with attacks by criminals.
People familiar with the Federal Bureau of Investigation’s programs
say that the use of hacking tools under court orders has grown as agents
seek to keep up with suspects who use new communications technology,
including some types of online chat and encryption tools. The use of
such communications, which can’t be wiretapped like a phone, is called
“going dark” among law enforcement.
