Update: How many users were affected by the DISA breach?

Andrew Eversden has an update on a breach previously noted on this site:

A breach of a system hosted by the Defense Information Systems Agency, the Department of Defense’s primary IT support agency, affected “approximately 200,000” users after a malicious actor may have gained access to names and Social Security numbers, according to a Pentagon spokesman.

The Department of Defense continues to decline to provide additional details:

Prichard declined to specify what network was breached, only that it was hosted by DISA. He also declined to comment on how long the actor was in the network.

“DoD and DISA take the security of our people, information (or data) and operations very seriously and actively monitor potential threats,” Prichard said. “For operational security reasons, the department does not comment on the actions taken to mitigate risks or vulnerabilities.”
