Foreign Agents Suspected in Cyberattack on Congressional Budget Office
Imagine the CBO is like a scorekeeper for Congress, telling everyone how much new laws might cost money.
Someone sneaky, who is thought to be from another country, broke into the CBO's computer system.
This is worrying because they might have seen private emails and messages between lawmakers and the scorekeepers.
Because of this, some people in Congress are being extra careful and not sending emails to the CBO for now.
The CBO is working hard to fix the problem, check what might have been seen, and make their computers safer.
They say they catch threats often and are always trying to be more secure.
They hope they found out about this problem early enough to stop too much bad stuff from happening.
The Congressional Budget Office (CBO) has been targeted by a cyberattack.
Suspected foreign agents are believed to be responsible for the breach.
Sensitive information such as emails and internal communications may have been exposed.
Some congressional offices have temporarily stopped emailing the CBO as a precaution.
The CBO has confirmed the incident and is investigating while continuing its work.
