Former government officials say they fear the Securities and Exchange Commission’s fraud lawsuit against the IT company SolarWinds and its chief information security officer over its massive 2019-2020 data breach will cause many companies to ”think twice” about reporting cyberattacks to law enforcement.

They say that those attacks, often originating overseas, are a mounting threat to the nation’s national security and that close cooperation and information-sharing between the public and private sectors is a key line of defense.
