The Microsoft president said the SolarWinds hack was the biggest the world has ever seen. In an interview Sunday, Brad Smith said the malicious operation required more than 1,000 engineers.
The hackers reportedly breached the SolarWinds software, giving them access to several companies and government offices. The U.S. government said Russian criminals are the possible culprits and added hacking aimed at collecting data rather than destroying it.

Smith said the malware has been installed through a company-wide upgrade.
“I think from a software engineering perspective, I think it’s fair to say that this is the biggest and most sophisticated attack the world has ever seen,” Smith said. “When this update reached 18,000 organizations around the world, so did this malware.”
Cybersecurity experts are trying to determine the full scope of the attack and said it will be difficult to completely remove infiltrators from the system.
