A growing number of cyberattacks have occurred on US businesses, local governments, and public systems since the start of 2021.
These attacks usually originate from outside the US, in countries like Russia and China, experts who spoke to Insider earlier in June said. Tyler Moore, a professor of cybersecurity and information at the University of Tulsa, said there were three kinds of major cyber attacks: ransomware attacks, espionage attacks, and email compromise attacks.
"There was a big increase in ransomware attacks in 2020 that continued in 2021," Allan Liska, who works on the computer security incident response (CSIRT) at the cybersecurity company Recorded Future, previously told Insider.
"What I think we're starting to see is ransomware attacks that have more of an impact on a broad swath of consumers," he said.
President Joe Biden earlier this year placed sanctions on Russia for its involvement in the attack on SolarWinds, which was reported last year. Biden is also expected to address cybercrime when he meets with Russian President Vladimir Putin in Geneva on Wednesday.
These are the cyberattacks that US companies, agencies, and institutions have faced so far this year.
