Issue: How to Recover Files Encrypted by Petya Ransomware?
Please help! My all files were encrypted by Petya ransomware, and I haven’t heard about any decryption tools so far. Does this mean that it is impossible to decrypt files encrypted by Petya? Needless to say, these records mean the world to me…
Petya is a file-encrypting virus that belongs to ransomware category. It first emerged in 2016; however, it attracted the most media attention after the 2017 cyber attack that primarily targeted Ukraine.
According to experts, the cyber criminals used the same Windows SMBv1 vulnerability that the infamous WannaCry ransomware used. Microsoft has already patched the vulnerability, however, many computer users failed to install the update in time. Petya ransomware encrypts all files on the system and demands $300 from the victim, promising to provide the decryption key in return.
The ransomware has compromised computer networks of companies such as “Rosneft” (Russian oil giant), “Kyivenergo,” “Ukrenergo,” National Bank of Ukraine, Oschadbank, and many others.
However, we must point out that Petya virus that was used in 2017 cyber attack slightly differs from the previous and original virus’ versions. After the Petya-based ransomware outbreak in June, the author of the original Petya variants known as Janus released the master decryption key, which now can be used to decrypt files locked by Red Petya, Green Petya, and Mischa. Using the published key, a security researcher known as Hasherezade has created a free decryption tool.
According to the researcher, certain Petya versions function in a slightly different way. The virus either encrypts Master File Table or cripples all files on the computer like a traditional ransomware virus. Luckily, there is no difference which method the virus used on your computer – the Petya Decryptor works for both cases.
Before you start decrypting your files, we must warn you to create an extra backup of the encrypted data and store it somewhere safe. The reason why we advise doing so is that the virus may hang during the data recovery procedure, and that can cause permanent damage to encrypted files.

Recover files and other system components automatically
To recover your files and other system components, you can use free guides by ugetfix.com experts. However, if you feel that you are not experienced enough to implement the whole recovery process yourself, we recommend using recovery solutions listed below. We have tested each of these programs and their effectiveness for you, so all you need to do is to let these tools do all the work.
Prevent websites, ISP, and other parties from tracking you
Private Internet Access is a VPN that can prevent your Internet Service Provider, the government, and third-parties from tracking your online and allow you to stay completely anonymous. The software provides dedicated servers for torrenting and streaming, ensuring optimal performance and not slowing you down. You can also bypass geo-restrictions and view such services as Netflix, BBC, Disney+, and other popular streaming services without limitations, regardless of where you are.
A VPN is also crucial when it comes to user privacy. Online trackers such as cookies can not only be used by social media platforms and other websites but also your Internet Service Provider and the government. Even if you apply the most secure settings via your web browser, you can still be tracked via apps that you are connected to the internet. Besides, privacy-focused browsers like Tor is are not an optimal choice due to diminished connection speed.
Therefore, to stay completely anonymous and prevent the ISP and the government from spying on you, you should employ Private Internet Access VPN. It will allow you to connect to the internet while being completely anonymous, prevent trackers, ads, as well as malicious content. Most importantly, you will prevent the illegal surveillance activities that NSA and other governmental institutions are performing behind your back.
Recover your lost files quickly
Unforeseen circumstances can happen at any time while using the computer: it can turn off due to a power cut, a Blue Screen of Death (BSoD) can occur, or random Windows updates can decide to reboot the machine when you went away for a few minutes. As a result, your schoolwork, important documents, and other data might be lost.
Additionally, you might also be attacked by malware that can corrupt your Windows or encrypt files with a robust encryption algorithm, and ask for a ransom in Bitcoin for the decryption tool. Cybercriminals might not deliver what they promised, however, so it is better to attempt alternative file recovery methods that could help you to retrieve at least some portion of the lost data.
Data recovery software is one of the options that could help you recover your files. Once you delete a file, it does not vanish into thin air – it remains on your system as long as no new data is written on top of it. Data Recovery Pro is recovery software that searchers for working copies of deleted files within your hard drive. By using the tool, you can prevent loss of valuable documents, school work, personal pictures, and other crucial files.
