The Petya Ransomware Attack: A One Minute Briefing

What do we know so far?

1. It’s a new strain of the Petya ransomware virus, which has existed since 2016

2. Also referred to as GoldenEye and PetrWrap

3. What makes Petya different from previous strains, is that it now includes the EternalBlue exploit as a way to propagate inside a targeted network

4. It started in Ukraine, and infections have since been reported in countries across the globe, including Germany, US, Netherlands and the UK

5. It reportedly hit 2,000 companies. High-profile victims include Maersk Group, pharmaceutical giant Merck, the Chernobyl nuclear facility and British advertising agency WPP

6. New victims are still emerging, and the full extent of the attack is still unknown

7. The virus got in through a vulnerability in the Windows operating system, attacking the Server Messaging Block service – which is used to share files and printers across local networks

8. Once infected, the virus locks the computer and encrypts the files on them. It then demands Bitcoin to be decrypted

9. So far it has raised just $9,618 through release payments.
