Yes, you read right above….No, we’re not scaring you. Yes, it’s(Petya) kind of ransomware or WannaCry the one that infected about 3,00,000 systems within 72 hours on 12th May.
According to the latest report from sources of The Hacker News, a new form of ransomware attack – Petya is started spreading. Which is also known as Petwrap, works on the same vulnerability of Windows SMBv1 which was used in WannaCry to infect the systems.
Petya is also kind of ransomware demanding around 300$ in form of bitcoin but works differently than WannaCry. Petya does not encrypt files of targetted system but gone beyond that & reached the root of it. Petya reboots the computer of victim & encrypts the hard disk’s master file table (MFT) which affects the functionality of master boot record (MBR) & seize the files names, sizes & location of hard disk.
As of now, Petya ransomware infected many Banks, Telecom, Businesses & Power Companies. It also infected Russian state-owned oil giant Rosneft, Ukrainian state electricity suppliers, “Kyivenergo” and “Ukrenergo”.
Many of the infected victims started paying to unlock their files, as of now around 20 peoples have already paid 300$ towards the hacker’s bitcoin address 1Mz7153HMuxXTuR2R1t78mGSdzaAtNbBWX .
Still thinking how all this mess started, it all started with the leaked by Shadow Brokers hacking group which leaked the NSA’s windows hacking tools containing the EternalBlue exploit that targets SMB file-sharing services on Microsoft’s Windows systems. Well, surprisingly that’s what one of Twitter user xXToffeeXx (@PolarTofee) found the code for eternalblue inside Petya based ransomware.
