Dozens of U.S. Treasury Department email accounts were breached as part of the massive SolarWinds supply chain attack, according to a senior Democratic senator.
"The hack of the Treasury Department appears to be significant," says Sen. Ron Wyden, D-Ore., the top Democrat on the Senate Finance Committee, in a statement. “According to Treasury staff, the agency suffered a serious breach, beginning in July, the full depth of which isn’t known."
He says an investigation into exactly what was accessed or stolen remains ongoing, but that "dozens of email accounts were compromised."
