DC riots: Attack on Capitol may pose cybersecurity risk

The pro-Trump mob at the U.S. Capitol on Wednesday that stormed the Senate floor and Capitol rotunda may have breached more than just the building’s physical security.

Photos show rioters in congressional offices, including that of House Speaker Nancy Pelosi (D-San Francisco). Any computers left on could be vulnerable, and so could papers — such as personal schedules or mail — that weren’t locked away, information security experts said. Sen. Jeff Merkley (D-Ore.) said his office was ransacked and a laptop stolen. Officials also said multiple electronic items were taken from the building, according to CNN.

What does this mean for the security of the nation’s information? Here are insights from experts who spoke with The Times.

Does the invasion of the Capitol pose a cybersecurity risk?

It depends. If rioters got their hands on congressional computers that were still logged in, they may have been able to access information. But if those computers were encrypted, they wouldn’t be able to get anything, said Jesse Varsalone, associate professor of computer networks and cybersecurity at University of Maryland Global Campus.

However, if a computer was encrypted but documents were left open onscreen, that information would already have been decrypted and could have been read, said Suzanne Spaulding, an advisor to Nozomi Networks and former undersecretary for the Department of Homeland Security. That means members of the mob could have snapped images of documents such as emails.

“I would not assume right off the bat that the folks who broke into the Capitol yesterday, forced their way in, had folks whose objective and skillset was to use their physical access to gain access to the IT system, to sensitive information,” she said. “But … if someone takes a laptop, they can later decide, ‘Hey, this could be really interesting. I don’t have the skills to exploit it, but I’m going to find someone who does.’”

The theft of a laptop, as from Merkley’s office, poses special concern because the machine is part of a federal network and could help outsiders access the entire network.

“That’s the concern about a stolen laptop,” Spaulding said. “It’s not just…
