Symantec

Security firm Symantec was attacked by a hacker back in February 2021 in which the hackers extracted some of the data.

This comprises not only passwords but a list of Symantec clients -- including government agencies.

The hacker was able to access a list of clients using Symantec's CloudSOC services, account managers and account numbers.
