Frend ransomware removal instructions

What is Frend?

Discovered by Jakub Kroustek, Frend is a new variant of high-risk ransomware called Dharma. Once infiltrated, Frend encrypts most stored files and appends filenames with the ".frend" extension plus the victim's ID and developer's email address. For instance, "sample.jpg" is renamed to "[].frend". Once data is encrypted, Frend places the "FILES ENCRYPTED.txt" text file on the victim's desktop and opens a pop-up window.

The new text file contains a short message informing victims that data is encrypted and that they must contact cyber criminals if they wish to restore it. The pop-up window provides a little more information. It is stated that the only way to restore data is to purchase a decryption tool from Frend's developers, since only they are capable of decrypting data. Unfortunately, this information is accurate. It is currently not known whether Frend uses symmetric or asymmetric cryptography, however, each victim receives a unique decryption key necessary to restore data. Cyber criminals hide all keys on remote servers. Therefore, to receive a decryption key (or tool with the key embedded within), users are encouraged to pay a ransom. The cost is not specified (these details are provided via email), however, it is stated that the cost depends on how quickly victims contact these people. Payment must be paid in the Bitcoin cryptocurrency. Regardless of the cost, do not pay. Research shows that many cyber criminals ignore victims, once payments are submitted. Therefore, people send money and receive nothing in return - they simply support cyber criminals' malicious businesses. We strongly advise you to ignore all requests to contact these people or pay any ransoms. Unfortunately, there are no tools capable of cracking Frend encryption and restoring data free of charge. You can only restore everything from a backup.

The internet is full of ransomware-type viruses that all have very similar characteristics. For example, Cryptotes, Maoloa, CryptoID, Cosanostra, _Write_To_Emails_, and many others. As with Frend, these viruses encrypt data and make ransom demands. In most cases, they have just two major differences: type of encryption algorithm used and size of ransom. Unfortunately, most use AES, RSA, or other similar algorithms that generate unique decryption keys. Therefore, in most cases, it is impossible to restore data without developers' involvement. The only possible scenarios are ransomware not being fully developed or having certain bugs/flaws (e.g., the key is hard-coded, stored locally, or similar). To prevent data loss, we strongly advise you to maintain regular backups, however, store them on remote servers or unplugged storage devices, otherwise these infections will encrypt backups together with regular data.

How did ransomware infect my computer?

Although it is currently not known exactly how developers proliferate Frend, there are several methods that are popular among cyber criminals: spam email campaigns, third party software download sources, fake software update tools, cracks, and trojans. Spam campaigns are used to send deceptive emails with malicious attachments. Criminals send messages encouraging users to open attached links/files. By opening them, users inadvertently trigger a computer infection. Unofficial download sources are used to proliferate viruses by presenting them as legitimate software. Users are simply tricked into downloading and installing malware. Fake updaters infect computers by exploiting outdated software bugs/flaws or simply downloading/installing malware rather than the updates. Cracking tools bypass software activation, however, rather than gaining access to paid features, users infect their computers with high-risk viruses. Finally, trojans are malicious applications designed to cause so-called "chain infections" - after infiltrating computers, they continually inject additional malware.

Threat Summary:
NameFrend virus
Threat TypeRansomware, Crypto Virus, Files locker
SymptomsCan't open files stored on your computer, previously functional files now have a different extension, for example my.docx.locked. A ransom demanding message is displayed on your desktop. Cyber criminals are asking to pay a ransom (usually in bitcoins) to unlock your files.
Distribution methodsInfected email attachments (macros), torrent websites, malicious ads.
DamageAll 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.

To eliminate Frend virus our malware researchers recommend scanning your computer with Spyhunter.

How to protect yourself from ransomware infections?

Lack of knowledge and careless behavior are the main reasons for computer infections. The key to safety is caution. Therefore, pay attention when browsing the internet and downloading/installing/updating software. We strongly recommend that you carefully analyze each email received. If the sender seems suspicious/unrecognizable and the attachment is irrelevant, do not open anything and delete the email immediately. Furthermore, download your programs from official sources only, preferably using direct download links. Third party download/installation tools are often used to proliferate viruses, and thus you should avoid them. The same rule applies to software updates. Keep installed apps/operating system up-to-date, however, this should be achieved through implemented functions or tools provided by the official developer. We strongly recommend that you never use software cracking tools, since software piracy is considered a cyber crime (you are stealing from software developers) and it increases the chances of computer infection. Have a reputable anti-virus/anti-spyware suite installed and running - these tools commonly detect and eliminate malware before it harms the system. If your computer is already infected with Frend, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.
