A ransomware attack on JBS, the world's largest meatpacker, by a criminal group likely based in Russia has strengthened the Biden administration's resolve to hold Moscow responsible for costly cyber assaults — even if they are not directly linked to the Kremlin.

U.S. President Joe Biden has launched a review of the threat posed by ransomware attacks and he will discuss the issue of harboring such hackers with Russian President Vladimir Putin this month, the White House said on Wednesday.

"President Biden certainly thinks that President Putin and the Russian government has a role to play in stopping and preventing these attacks," White House press secretary Jen Psaki said Wednesday.
