Hackers froze the work of computer systems of the Mexican oil company Pemex. They gave the company 48 hours to pay 565 BTC ($ 4.8 million), according to Reuters.
Pemex currently has huge debts due to reduced oil production. The company has already refused to pay the ransom. According to Mexico’s Minister of Energy Rocio Nahle, the attack came at the headquarters in Mexico City, but work continues on the fields.
Attackers used the DoppelPaymer tool. In the past, it was used to attack the Chilean Ministry of Agrarian Policy and municipality systems in a Texas city.
Recall that in May a number of US government agencies were attacked by ransomware using the EternalBlue program developed by the NSA.
