The ransomware group behind the Kaseya supply-chain attack is demanding a $70 million ransom in Bitcoin for the tool that allows all affected businesses to recover their files.

Last week, a massive REvil ransomware attack affects multiple managed service providers and their clients through a reported Kaseya supply-chain attack.

The attack was propagated through Kaseya VSA cloud-based solution used by managed service providers (MSPs) to monitor customer systems and for patch management.

In a post on their leak site, the threat actor says that they locked more than a million systems and are willing to negotiate for a universal decryptor, starting from $70 million.

This is the highest ransom demand to date, the previous record also belonging to REvil, asking $50 million after attacking Taiwanese electronic and computer maker Acer.
