Petya Ransomware: More dangerous than WannaCry?


Nobody has fully recovered from the last WannaCry ransomware attack and now there are new attacks spreading throughout the world. This time it is a threat called Petya ransomware.

What is Petya ransomware?

Petya ransomware was a malware that was created in 2006. Now, it has been modified and the new variant has been used in the recent attacks. It locks users' PC and encrypts files. The hackers behind the attacks ask for ransom in bitcoin in order to decrypt users' files.

However, experts claim that Petya is not a traditional ransomware. It is more dangerous than WannaCry because it is a specific type of ransomware. Attackers ask for ransom in Bitcoin making you believe that your files will be decrypted. But this time, it not the case. Petya's source code revealed that it is impossible to recover and decrypt files once infected.

It can infect your PC in more ways than WannaCry or any other ransomware. It is very different from the common ransomware. It installs itself to start before Windows, causes a BSOD in Windows, and after Windows restarts, it mimics a file repair, but in reality, it encrypts the MFT(Master File Table). This type of threat will be harder to overcome. This is a cyber attack meant to sabotage and destroy users' PC.

Recent attacks

The attacks listed below are just some of the attacks, so it is not a surprise that Petya caused chaos around the world.

- Russia's oil company
- major Ukranian banks (including the Central bank) and companies
- the airport in Kiev
- British advertising agency
- U.S. pharmaceutical company Merck
- Cadbury chocolate plant in Australia
- a major shipping firm in Netherlands

How to protect yourself

Petya ransomware is a specific type of a cyber attack, which means that you will need to take extra measures in order to protect your PC.

The first thing you need to do is update your operating system. An update will improve the stability of your PC and will not be an easy target. You also need to have an antivirus and antimalware software installed on your PC and mobile phone.

Because Petya works totally different than other ransomware, most generic ransomware protection was totally ineffective against this threat and failed to protect end users worldwide. 

But according to MRG Effitas, our Zemana AntiMalware proved to be the best protection against Petya ransomware. Check out the below image:

However, few experts believe that this worldwide spreading infection is only disguised as ransomware. It uses the NSA's Eternal Blue Exploit and has affected many European countries including Ukraine, Poland and Germany. However, other continents were not spared as well.

Nevertheless, no one should take the risk so everyone should take needed precautions asap! 

All Zemana products use the same technology designed to protect you from both traditional and new types of malware. So, whether you have Zemana AntiLogger or Zemana AntiMalware, your PC will remain protected.

As we have mentioned in our previous blogs, experts predicted a high number of ransomware attacks in 2017 targeting both your PC and your mobile device. It seems that their predictions are already coming true. Protect yourself in time with Zemana AntiMalware and enjoy the online world carefree.
