SolarWinds Hack Grabs Senate Spotlight With CEO in the Hot Seat

The suspected Russian hackers who compromised software created by SolarWinds Corp. to break into American agencies and companies used a cyber weapon “so potentially powerful it could have been crippling,” according to Senator Mark Warner, chairman of the Senate Intelligence Committee.

Warner, a Democrat from Virginia, called the hacking campaign “a level of attack and level of penetration that is much greater than what we have seen” in previous cyber-attacks on the U.S. His comments came during a Monday interview with Bloomberg News, a day before executives from key technology companies, including SolarWinds, testify before his committee about the sprawling breach.
