Easy tips to delete EFDC ransomware and decrypt data

EFDC ransomware encrypts stored files and then demands ransom payment for the decryption. During the encryption process, it renames filenames of each of the encrypted files with .Efdc extension. For example, a file 1.jpg would become 1.jpg.efdc, 2.jpg become 2.jpg.efdc and so on. As its ransom note, it creates _readme.txt text file and drops it onto the desktop. The ransomware belongs to the infamous DJVU ransomware family.

As written in _readme.txt ransom note EFDC encrypts all the files, including images, databases, documents and other files with the strongest encryption algorithm. The victims can decrypt the files only with a decryption tool and a unique decryption key that the crooks have and for which they are asked to pay a ransom of $980.

The payment is asked to be done in Bitcoin cryptocurrency. The ransom note provides the Bitcoin address belongs to the crooks and also a Bitcoin purchasing link. There are two email addresses – [email protected] and [email protected] mentioned in the note supposedly to contact them to proceed with the files decryption process.

It is mentioned in the note that if the victims contact the crooks within 72 hours of the encryption, they would get a huge 50% discount on the price of the decryption tool and thus the price of the tool for them would become$490 only. Prior to the payment, as a proof, the victims are offered to send one encrypted file with less than 1 MB file for free decryption.

As a rule, ransomware victims cannot recover files without paying a ransom if they do not have backups available. It is possible to decrypt the files using Shadow Copies and third party data recovery tools from third party tools. But, no guarantee that the Volume Shadow Copies were not affected by the ransomware and third party tool certainly work in the files recovery process.

However, you should attempt for these files recovery alternatives only as contacting/ paying the crooks is not recommendable. These people often do not provide the decryption tool even if all their demands are met. Another important thing is to remove EFDC ransomware from the system because it may encrypt more files or infect other computers in networks.

How did EFDC ransomware enter my system?

Malware are often distributed using spam emails, fake software updaters, Trojans, questionable download sources for downloading programs and software cracking tools. Emails used to spread malware by including a malicious attachment or link in them. Users infect their systems when they download and open the malicious files.

Fake software updaters are supposed to fix or updated installed software. But, they install malware in regular way or infect systems by exploiting bugs/ flaws of outdated software. Trojans are malicious software that can install their payload on systems. They are often distributed using the methods described in the section. There are different types of Trojans, for example, info-stealer Trojan.

Third party downloaders, free file hosting sites or freeware download pages, p2p networks like torrent clients, eMule and so on are the examples of unreliable sources that can be used to distribute malware too. Users infect systems through them by executing downloaded malicious files. Software cracking tools infect system by allegedly bypassing activation keys of paid software.

How to prevent ransomware infection?

Programs and files should always be downloaded from official, legit pages and via direct links. It is not safe to use p2p networks, unofficial pages, third-party downloaders, installers and etc to download or install programs or files – they often distribute malicious software. Attachments in any irrelevant emails received from unknown, suspicious senders should never be opened as well.

Any installed software should have to be updated/ activated using tools/ functions from their official developers. And last but not the least the computer should be scanned for viruses on regular basis. It is recommended to do that using some reputable antivirus tool. If system is already infected with EFDC ransomware, we recommend you to use some reputable antivirus tool and remove it right away.

To restore encrypted files on your machine, you can take a trial with a suggested data recovery tool to check if it can help achieving your files back.

Prevention tips to protect your System from EFDC ransomware related attacks in future

  • You should have strong backup of all files and data stored in your computer because some ransomware is designed to look for network shares and encrypt all files stored in your machine. You would do well to store data backups on secure cloud server with high-level encryption and multiple-factor authentication.
  • Ransomware type virus often relies on exploit kits to gain illicit access to a System or network. If you run outdated or obsolete software on your computer, then you are in risk of ransomware because the software developers are not putting out security updates anymore. To remove abandonware and replace it with software still being supported by manufacturer.
  • The cybercriminals behind ransomware attack are using former banking Trojan as delivery vehicle for ransomware. It relies on malspam to infect your System and get foothold on your network. Once it gain access to your network, it shows worm like behaviour spreading from System to System using list of common passwords.
  • You should be alert while surfing online and avoid installing freeware from unknown sources, stop opening attachments coming from unknown emails and click on ads or popup messages after double reading.
  • Don’t pay extortion money in case of attack. We recommended you to stop paying ransom and FBI agrees. Cybercriminals don’t have scruples and there is no guarantee you will get files back. By paying extortion money, you are showing cybercriminals that ransomware attack work.
