WASHINGTON (AP) — An FBI operation that gave law enforcement remote access to hundreds of computers to counter a massive hack of Microsoft Exchange email server software is a tool that is likely to be deployed “judiciously” in the future as the Justice Department, aware of privacy concerns, develops a framework for its use, a top national security official said Wednesday.

The department this month announced that it had obtained a warrant from a federal judge in Texas to remove web shells, or malicious code that gives hackers a foothold into networks, from hundreds of vulnerable computers affected by a hack that Microsoft has blamed on a group operating from China.
