(Reuters) - As U.S. President Joe Biden prepares to confront Russian President Vladimir Putin over ransomware gangs in his country that twice recently targeted critical American infrastructure, his administration is publicly blaming the Russian government for allowing those criminals to profit without prosecution.

The FBI and private cybersecurity companies have not disclosed any evidence showing Russian government involvement in the ransomware attacks on U.S. fuel transporter Colonial Pipeline Co and meatpacker JBS SA of Brazil. Putin has called the idea that Russia was responsible absurd.
