Data privacy lobbyists are working to stop new legislation that would allow U.S government agencies to access millions of Americans’ computers. The new rule is a modification to Rule 41 of the Federal Rules of Criminal Procedure.

The Justice Department indicated the new rule is necessary to keep up with new technologies used by cyber criminals, specifically botnets. The change to Rule 41 would allow U.S investigative agencies to gain access to multiple computers with only one warrant from a judge, instead of needing multiple warrants to gain access to devices in different areas.

Privacy advocates are working against the new rule because of its ability to affect large amounts of unsuspecting citizens, and potentially damage their devices. Google Inc. indicates government hacking could make the accessed devices more vulnerable.

The new legislation will automatically begin December 1, 2016 unless congress chooses to cancel its enactment.
