Petya: What You Need To Know About The Latest Ransomware Attack

5 years ago | by Chris O'Brien

Petya is using the same tools exploited by WannaCry, and its taking the world by storm.


A new wave of Ransomware known as Petya has recently been unleashed, having reportedly already affected a number of companies on a global scale.

Petya is said to use the same tools exploited by the recent WannaCry attacks. The ransomware is reported to infect computers on a local network, by delivering a phishing email with a .doc attachment, and using a vulnerability within Microsoft Office and Wordpad to execute and begin a chain of exploitation. The attack has an automated shutdown feature after 1hr of the initial infection, by which time it will have already completed its local network scan. This shutdown feature signifies the beginning of the encryption process of not only your computer, but all others in your network, too.

If your machine reboots and you see this message, shut your systems down IMMEDIATELY. As mentioned, this is the beginning of the encryption process – if you manage to power off in time, your files are expected to be fine.

According to CRN, a Cadbury chocolate factory in Tasmania could be the first Australian victim of this global ransomware attack, reportedly having its activity suspended due to a variant of the Petya virus known as Goldeneye. Staff workstations have been locked, and are being held ransom unless they send a disclosed amount of Bitcoin to a specified address.
