SolarWinds CEO Says Hackers Accessed Its Office 365 Accounts for Months

The newly appointed chief executive of SolarWinds Corp. is still trying to unravel how his company became a primary vector for hackers in a massive attack revealed last year, but said evidence is emerging that they were lurking in the company’s Office 365 email system for months. The hackers had accessed at least one of the company’s Office 365 accounts by December 2019, and then leapfrogged to other Office 365 accounts used by the company, Sudhakar Ramakrishna said in an interview.
