Delaware County information systems in the American state of Pennsylvania were attacked by the DoppelPaymer encryption virus. The authorities paid the extortionists $500,000 in bitcoins, according to Bleeping Computer.
The attack did not affect the voting and emergency Bitcoin Blueprint response systems. The encryptor’s operators gained access to police reports, payment documents, procurement information and other databases.
„Computer security specialists were invited to investigate the incident to determine the nature and extent of the break-in. We are working to restore the functionality of the systems,“ said the district representatives.
After the ransom was transferred, hackers advised the authorities to change passwords and gave advice on setting up a Windows domain to activate protection against the Mimikatz utility.
Earlier, Positive Technologies specialists found out that cyber extortionists switched from mass to targeted attacks. Their victims are large companies that can pay a large ransom.
Let us remind you that DoppelPaymer was among the top five most dangerous encryptors together with NetWalker, Ryuk, Maze and REvil.
