Hackers behind the huge ransomware attack in the IT company, Kaseya, have asked for $70 Million in Bitcoin to decrypt the files.

The firm Kaseya, which helps firms remotely manage their IT infrastructure, was hit Friday in an attack believed to have been carried out by the Russian-linked cybercrime gang REvil. The attack infected hundreds of companies in at least 17 countries.

The group is best known for the recent attack on JBS meat processing. In that instance, REvil was able to extort $11 million from the firm in a ransomware payment.

The Miami-based firm Kaseya said a broad array of small businesses — including financial services, travel and leisure, and public agencies on all continents — were hit in this latest ransomware attack.
