P3rf0rm4 ransomware removal instructions

What is P3rf0rm4?

First discovered by malware security researcher, fuyun, P3rf0rm4 is yet another ransomware-type virus that belongs to the Dharma malware family. After successful infiltration, P3rf0rm4 encrypts most stored files and appends filenames with the ".p3rf0rm4" extension plus the victim's unique ID and developer's email address. For instance, "sample.jpg" might be renamed to a filename such as "sample.jpg_J5oayd_{babyfromparadise666@gmail.com}.p3rf0rm4". Once data is encrypted, P3rf0rm4 opens a pop-up window and places a text file called "Instructions with your files.txt" on the desktop.

As with other variants of Dharma, P3rf0rm4's text file delivers a message stating that data is encrypted and that victims must contact cyber criminals via an email address provided. The pop-up message provides a little more information. It states that data recovery requires a unique decryption key and a decryption tool. Unfortunately, this information is accurate. It is currently unknown whether P3rf0rm4 uses symmetric or asymmetric cryptography. In any case, each victim receives an individual decryption key. Restoring data without the key is impossible. Criminals store them on remote servers and make ransom demands - to receive a decryption key and tool, each victim must pay a ransom. The cost is not specified but supposedly depends on how quickly victims make contact. Cyber criminals typically demand $500-1500 in Bitcoins, Ethereum, DASH, Monero or another cryptocurrency. Victims are also allowed to attach one selected file. Criminals will then supposedly restore and return it as a 'guarantee' that decryption is possible and that these people can be trusted. Regardless of the cost, do not pay. Research shows that these people often ignore victims, once payments are submitted. Therefore, paying usually gives no positive result. We strongly advise you to ignore all requests to submit payments or even contact these people. Unfortunately, there are no tools capable of restoring data encrypted by P3rf0rm4 free of charge. Thus, the only solution is to restore everything from a backup, if one has been created.

P3rf0rm4 is virtually identical to dozens of other ransomware-type viruses. RobbinhoodMr-X666 and L1LL are just some examples from many. Note that although these infections are developed by different cyber criminals, their behavior is virtually identical - virtually all encrypt data and make ransom demands. These viruses typically have just two major differences: cost of decryption and type of encryption algorithm used. Unfortunately, such infections usually employ algorithms that generate unique decryption keys. Therefore, unless the virus is still in development or has certain bugs/flaws (e.g., the key is hard-coded, stored locally, or similar), restoring data manually is impossible. Ransomware is one of the main reasons why you should maintain regular data backups, however, store them on a remote server (e.g., Cloud) or unplugged storage device (external hard drive, Flash drive or similar). This will prevent ransomware from encrypting backups together with regular data.

How did ransomware infect my computer?

Ransomware-type viruses are usually proliferated using fake software cracks/updaters, trojans, spam email campaigns, and unofficial software download sources. Cracking tools activate paid software free of charge, however, most are fake and developers use them to proliferate malware. Thus, users typically end up infecting their computers, rather than gaining access to paid features. Trojans are essentially infectious applications that, once infiltrated, inject additional malware into the system. Cyber criminals use spam campaigns to send hundreds of thousands of deceptive emails which contain messages encouraging users to open attached malicious files/links, however, opening them typically leads to various system infections. Third party download sources (freeware download websites, free file hosting sites, torrents, eMule, etc.) are used to present malicious executables as legitimate software. Users are tricked into downloading and installing malware rather than updates.

Threat Summary:

Threat Type Ransomware, Crypto Virus, Files locker.
Symptoms Cannot open files stored on your computer, previously functional files now have a different extension (for example, my.docx.locked). A ransom demand message is displayed on your desktop. Cyber criminals demand a ransom payment (usually in Bitcoins) to unlock your files.
Distribution methods Infected email attachments (macros), torrent websites, malicious ads.
Damage All files are encrypted and cannot be opened without paying a ransom. Additional password-stealing trojans and malware infections can be installed together with a ransomware infection.

How to protect yourself from ransomware infections?

The main reasons for computer infections are poor knowledge and careless behavior. Caution is the key to computer safety. Therefore, pay close attention when browsing the internet and downloading, installing, and updating software. You are advised to carefully analyze each email attachment received. If the received link/file is irrelevant or the sender seem suspicious, do not open anything. Furthermore, avoid using third party downloaders/installers, since they often include rogue programs. Software should be downloaded from official sources only, using direct download links. We recommend that you keep installed software and operating systems updated, however, this should be achieved through implemented functions or tools provided by the official developer. Software cracks should never be used, since software piracy is a cyber crime and the risk of infections is extremely high. Lastly, use a reputable anti-virus/anti-spyware suite, since these tools detect and eliminate malware before it harms the system. If your computer is already infected with P3rf0rm4, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the P3rf0rm4 ransomware virus infiltrating your PC).

select a restore point

6. In the opened window, click "Yes".

run system restore

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining P3rf0rm4 ransomware files.

To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of P3rf0rm4 are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.

To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.

Restoring files encrypted by CryptoDefense

If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.

To regain control of the files encrypted by P3rf0rm4, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.

To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as P3rf0rm4 ransomware.

Note that Windows 10 Fall Creators Update includes a "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in the Documents, Pictures, Videos, Music, Favorites as well as Desktop folders.

Controll Folder Access

Windows 10 users should install this update to protect their data from ransomware attacks. Here is more information on how to get this update and add an additional protection layer from ransomware infections.
