The Petya ransomware is receiving worldwide attention by attacking the governments, banks, electrical systems, communication systems, enterprises, and airports in several countries.
The attacking virus is the Petya ransomware variant, which spreads through combinations of the email, downloader and the worm. It exploits a vulnerability (CVE-2017-0199) through the RTF attachment in the emails. By releasing the downloader to obtain the host virus, it can form the initial nodes. After that, the virus spreads via the MS17-010 (EternalBlue) exploit and weak system passwords.
When the infection is done, it will encrypt the files with specific suffix, modify the MBR, add task schedules, and shut down the computer after waiting for a while. When the users restart their computers, the extortion information will be shown, asking the users to pay the bitcoin valued 300USD as the ransom.
