Hackers commit biggest ransomware attack on record

A cyberattack on the Miami-based company Kaseya appears so far to have compromised between 800 and 1,500 mostly small businesses, the company said. The victims were customers of companies that use Kaseya’s software to manage IT infrastructure. The attack hit a broad array of businesses around the world, including in financial services, travel and leisure, and the public sector.

Who is responsible? Authorities suspect the Russia-linked REvil gang in the attack, carried out on the eve of the Fourth of July. President Joe Biden said he ordered a “deep dive” by U.S. intelligence into the incident and the U.S. would respond if it determined the Kremlin was involved. The president added he thought the attack had a minimal effect on U.S. businesses.
