Recovering from the SolarWinds hack could take 18 months – MIT Technology Review

SolarWinds Orion, the network management product that was targeted, is used in tens of thousands of corporations and government agencies. Over 17,000 organizations downloaded the infected back door. The hackers were extraordinarily stealthy and specific in targeting, which is why it took so long to catch themand why its taking so long to understand their full impact.

The difficulty of uncovering the extent of the damage was summarized by Brad Smith, the president of Microsoft, in a congressional hearing last week.

Who knows the entirety of what happened here? he said. Right now, the attacker is the only one who knows the entirety of what they did.

Kevin Mandia, CEO of the security company FireEye, which raised the first alerts about the attack, told Congress that the hackers prioritized stealth above all else.

Disruption would have been easier than what they did, he said. They had focused, disciplined data theft. Its easier to just delete everything in blunt-force trauma and see what happens. They actually did more work than what it would have taken to go destructive.

CISA first heard about a problem when FireEye discovered that it had been hacked and notified the agency. The company regularly works closely with the US government, and although it wasnt legally obligated to tell anyone about the hack, it quickly shared news of the compromise with sensitive corporate networks.

It was Microsoft that told the US government federal networks had been compromised. The company shared that information with Wales on December 11, he said in an interview. Microsoft observed the hackers breaking into the Microsoft 365 cloud that is used by many government agencies. A day later, FireEye informed CISA of the back door in SolarWinds, a little-known but extremely widespread and powerful tool.

This signaled that the scale of the hack could be enormous. CISAs investigators ended up working straight through the holidays to help agencies hunt for the hackers in their networks.

These efforts were made even more complicated because Wales had only just taken over at the agency: days earlier, former director Chris Krebs had been fired by Donald Trump for repeatedly debunking White House disinformation about a stolen election.
