Ransomware group demands $70 million for Kaseya attack

The ransomware group REvil has demanded a $70 million payment in Bitcoin for a decryptor tool following its attack on the software vendor Kaseya, cyber researchers say.

The offer of a universal tool reflects the "logistical nightmare" REvil is now facing with thousands of potential victims to negotiate with, researcher Allan Liska at cybersecurity firm Recorded Future said.

 

"We know there are thousands of victims here. REvil [has] limited resources to handle negotiations and process keys," Liska said, calling this the biggest non-nation state supply chain attack ever, and possibly the second biggest ransomware attack ever.
