Cyber​​ attack extorts more than 350 organizations "hackers" ask for 70 million dollars

More than 350 organizations around the world this weekend suffered a ransomware cyber attack and it is feared that the information systems of many of them, including the physical stores of the Swedish supermarket chain Coop, were forced to close because the cash registers were not working. . The cyber attack was carried out by a group of cybercriminals called REvil who exploited the update system of IT services software company Kaseya to hide and spread ransomware. This company's systems were compromised and the ransomware leaked through its resellers to the end customers using the software. Revil operators published that more than 1 million devices had been affected and on Sunday night they demanded $ 70 million in bitcoin to provide universal decryption and restore company data.
