What is NotPetya ransomware virus?

The massive NotPetya attack cost millions of dollars for corporations

The image illustrating NotPetya virus

NotPetya is a ransomware virus that attacked thousands of computers with the help of Windows OS vulnerability. Malware caused problems not only for home computer users but corporations and infrastructure. Due to the malware attack, flights were delayed, and petrol stations ceased functioning properly. Two months after ransomware attack, companies are still counting the financial loss, and the sums of money reach to 200-300 million dollars per company.

The worldwide attack hit on the US, the UK[1], Spain, and, certainly, Ukraine[2] the hardest. However, the virus targeted Chernobyl power plant as employees had to take control of radiation levels manually.[3] So far, the virus:

  • corrupts MBR settings, individual malware samples encrypt files
  • demands 300 USD ransom
  • exploits Windows OS vulnerabilities
  • delivers for contact purposes
  • disguises as Petya, but functions as independent malware
  • targets the US, Europe and particularly Ukraine

The threat meddles with the boot settings preventing systems from starting normally. At this stage, the threat does not seem to append any extension to the files as it does not encrypt them, but in fact, causes system failure. According to the ransom message, the threat demands $300 and indicates them to transfer to

Fortunately, IT expert Lawrence Abrams found an antidote to the prevent the attack of the malware.[3] Not only companies globally have been struck but individuals as well. If you happen to be one of them, make sure you remove NotPetya with the assistance of an anti-spyware tool, such as ReimageIntego or Malwarebytes.

NotPetya attack might cost 200-300 million for A.P. Moller-Maersk

Danish shipping company A.P. Moller-Maersk was one of the victims of the massive ransomware attack on June 28th. Ransomware hit Maersk Line, APM Terminals and Damco that belongs to the shipping giant.

According to the company’s financial statement,[4] the attack caused a “significant business interruption” that had a negative financial impact. After the attack, computer systems were shut down in order to stop malware from spreading.

Within few days the work came back to normal. However, the company fully recovered after the ransomware infiltration only on July 9. Fortunately, A.P. Moller-Maersk did not lose any documents and hadn't suffered from the data breach.

However, NotPetya ransomware attack was an expensive lesson for the shipping company. This cyber attack proves that corporations have to pay more attention to cyber security and improve their current security systems in order to avoid financial loss.

Similarities to Petya and WannaCry viruses

The malware starts with the same remark as the notorious WannaCry threat:

Ooops, your important files are encrypted.
If you see this text, then your files are no longer accessible, because they have been encrypted. Perhaps you are busy looking for a way to recover your
files, but don’t waste your time. Nobody can recover your files without our
decryption service.
We guarantee that you can recover all your files safely and easily. All you
need to do is submit the payment and purchase the decryption key.
Please follow the instructions:
1. Send $300 worth of Bitcoin to the following address:
2. Send your Bitcoin wallet ID and personal installation key to e-mail
If you already purchased your key, please enter it below.

Though initially, the virtual community thought the malware is Petya as it also targeted Master Boot Record settings interfering with boot processes, now IT professionals claim that the infection disguises under the title of the previous title, actually, is a different malware.[5] At the moment, the virus bears the name of NotPetya virus.

It seems that the perpetrators have learned from WannaCry developers' mistakes. NotPetya malware also feeds on Windows vulnerabilities.

Despite the warnings from cyber security forces, the malware has managed to wreak havoc. International facilities such as airport did not update their systems which resulted in severe outcomes.

Interestingly, the first outbreak of the threat was spotted in Ukraine. It seems that the latter country has become a “test subject” for hackers. The former virus, WannaCry manifested its power there first. Right after the attack, XData virus struck Ukraine again.

The success of the attack hides behind NSA hacking tools

The cyber criminals have benefitted from previously leaked NSA hacking tools. NotPetya hijack is likely to occur if your operating system has been outdated. Mostly, Windows 7 versions have suffered the attack.

Fortunately, an “antidote” has been found – you have to create a text file entitled as perfc in your C:Windows folder.[6] It is likely that the malware might employ other distribution methods: spam emails and exploit kits. Now let us proceed to NotPetya removal section.

How to prevent from getting NotPetya ransomware virus

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.


Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
