RSFDD Virus Files of Ransomware — How to remove virus?

The Rsfdd virus belongs with the ransomware type of malicious agent. Ransomware of this type encrypts all user’s data on the computer (images, text files, excel sheets, music, videos, etc) and adds its own extension to every file, creating the ReadMe.txt text files in each directory containing encrypted files.

It is better to prevent, than repair and repent!

Rsfdd virus: what is known so far?

☝️ A strictly accurate description for the Rsfdd is “a ransomware infection”.

The renaming will be done by this pattern: id-*******.[email address].RSFDD. In the course of encryption, a file entitled, for instance, “report.docx” will be changed to “report.docx.idF1A7B939.[John.Karick@mailfence.com].RSFDD”.

In each folder that contains the encoded files, a ReadMe.txt notebook file will appear. It is a ransom money note. Therein you can find information on the ways of paying the ransom and some other remarks. The ransom note most probably contains a description of how to purchase the decryption tool from the racketeers. You can get this decoding tool after contacting John.Karick@mailfence.com by email. That is pretty much the scheme of the felony.

Rsfdd abstract:

In the picture below, you can see what a directory with files encrypted by the Rsfdd looks like. Each filename has the “.id-*******.[email address].RSFDD” extension appended to it.

That is how encrypted “.id-*******.[email address].RSFDD” files look.

How did Rsfdd ransomware end up on my PC?

There is a huge number of possible ways of ransomware injection.

Nowadays, there are three most popular ways for evil-doers to have the Rsfdd virus acting in your system. These are email spam, Trojan introduction and peer-to-peer file transfer.

If you access your mailbox and see letters that look like familiar notifications from utility services companies, delivery agencies like FedEx, Internet providers, and whatnot, but whose “from” field is strange to you, beware of opening those letters. They are most likely to have a malware file enclosed in them. Therefore, it is even more dangerous to open any attachments that come with emails like these.

Another option for ransom hunters is a Trojan virus model¹. A Trojan is an object that gets into your computer pretending to be something legal. Imagine, you download an installer for some program you want or an update for some program. But what is unboxed reveals itself a harmful program that corrupts your data. As the update file can have any title and any icon, you have to make sure that you can trust the resource of the stuff you’re downloading. The optimal thing is to trust the software companies’ official websites.

As for the peer-to-peer networks like torrent trackers or eMule, the threat is that they are even more trust-based than the rest of the Web. You can never guess what you download until you get it. So you’d better be using trustworthy resources. Also, it is a good idea to scan the directory containing the downloaded objects with the antivirus as soon as the downloading is done.

How do I get rid of the Rsfdd virus?

It is crucial to note that besides encrypting your data, the Rsfdd virus will most likely install the Azorult Spyware on your PC to get access to credentials to different accounts (including cryptocurrency wallets). The mentioned program can derive your logins and passwords from your browser’s auto-filling data.

Often racketeers would unblock some of your files to prove that they indeed have the decryption program. Since Rsfdd virus is a relatively new ransomware, anti-malware engineers have not yet found a method to undo its work. Nevertheless, the anti-ransomware tools are constantly upgraded, so the solution may soon arrive.

Sure thing, if the malefactors succeed in encoding victim’s critical files, the hopeless person will probably fulfill their demands. However, paying to racketeers gives no guarantee that you’re getting your blocked information back. It is still dangerous. After getting the money, the racketeers may send a wrong decryption code to the victim. There were reports about malefactors simply disappearing after getting the money without even writing back.

The best solution against ransomware is to have aan OS restore point or the copies of your critical files in the cloud storage or at least on an external storage. Obviously, that might be not enough. The most crucial thing could be that file you were working upon when it all went down. But at least it is something. It is also wise to scan your drives with the anti-malware utility after the system is rolled back.

There are other ransomware products, besides Rsfdd, that work similarly. For instance, 8zvpm, Hr1wf, Wixawm, and some others. The two major differences between them and the Rsfdd are the ransom amount and the encoding method. The rest is the same: files become encoded, their extensions altered, ransom notes are created in every folder containing encoded files.

Some lucky victims were able to decrypt the blocked files with the help of the free software provided by anti-malware experts. Sometimes the racketeers mistakenly send the decryption key to the wronged in the ransom note. Such an epic fail allows the injured part to restore the files. But naturally, one should never expect such a chance. Remember, ransomware is a bandits’ tool to lay their hands on the money of their victims.

How to avert ransomware injection?

Rsfdd ransomware doesn’t have a endless power, so as any similar malware.

You can armour your computer from its injection in several easy steps:

• Ignore any emails from unknown mailboxes with unknown addresses, or with content that has likely no connection to something you are expecting (how can you win in a lottery without even taking part in it?). In case the email subject is more or less something you are expecting, check all elements of the questionable email with caution. A fake letter will surely contain mistakes.
• Avoid using cracked or unknown software. Trojans are often shared as an element of cracked software, most likely under the guise of “patch” which prevents the license check. Understandably, dubious programs are very hard to distinguish from reliable software, because trojans sometimes have the functionality you seek. You can try to find information about this program on the anti-malware message boards, but the optimal way is not to use such software.
• And finally, to be sure about the safety of the files you downloaded, check them with GridinSoft Anti-Malware. This program will be a perfect defense for your personal computer.

Frequently Asked Questions

🤔 Is it possible to open “.id-*******.[email address].RSFDD” files?

Unfortunately, no. You need to decipher the “.id-*******.[email address].RSFDD” files first. Then you will be able to open them.

🤔 What should I do to make my files accessible as fast as possible?

Hopefully, you have made a copy of those important files. Otherwise, you might try to employ System Restore. The only question is whether you have saved any Restore Points that would be helpful now. All other solutions require time.

🤔 If GridinSoft deletes the Rsfdd malware, will it also delete my files that were encrypted?

Of course not. Your encrypted files are no threat to your PC.

GridinSoft Anti-Malware will remove the viruses from your system. The ransomware that has infected your device is must be still functional and it scans your system every so often to encrypt any new files you might create on your PC after the infection. As it has already been said, the Rsfdd malware does not come alone. It installs backdoors and keyloggers that can take your account passwords by trespass and provide criminals with easy access to your computer in the future.

🤔 What to do if the Rsfdd ransomware has blocked my computer and I can’t get the activation key.

If that happened, you need to prepare a memory stick with a previously installed Trojan Killer. Use Safe Mode to perform the cleaning. You see, the ransomware runs automatically as the system boots and encodes any new files created or imported into your computer. To block this function – use Safe Mode, which allows only the essential applications to run upon system boot. Consider reading our manual on running Windows in Safe Mode.

🤔 What could help the situation right now?

Many of the blocked files might still be at your disposal

• If you exchanged your important files by email, you could still download them from your online mailbox.
• You might have shared images or videos with your friends or family members. Simply ask them to give those pictures back to you.
• If you have initially got any of your files from the Web, you can try to do it again.
• Your messengers, social networks pages, and cloud drives might have all those files as well.
• It might be that you still have the needed files on your old computer, a notebook, cellphone, memory stick, etc.

USEFUL TIP: You can use file recovery programs⁴ to retrieve your lost information since ransomware blocks the copies of your files, removing the authentic ones. In the video below, you can learn how to use PhotoRec for such a restoration, but remember: you won’t be able to do it before you kill the virus with an anti-malware program.
