A bipartisan group of senators has proposed legislation that would prohibit law enforcement agencies from indiscriminately hacking users on the Internet.

The legislation, “Stopping Mass Hacking,” would prevent a change to Rule 41 of the Federal Rules of Criminal Procedure going into effect in December. The change, which was authorized by the Supreme Court in April, would allow agencies like the FBI to use one warrant to hack an unlimited number of computers using a so-called “botnet” attack.
