Distribution of .еfdc Virus
Efdc crypto virus is a devastating data locker ransomware that has been recently released in attack campaigns against computer users worldwide. Threat actors could be utilizing widely used tactics of distribution to infect computer systems.
One of the methods that may be used by the malicious actors behind Efdc cryptovirus include the coordination of SPAM email messages — they are used to spread the threat by sending out messages that pose as legitimate notifications sent by popular Internet portals or services that the targets may use. The virus files can be either directly attached or linked to the body. They can also be uploaded to fake download sites which are designed to appear like any of the popular Internet portals or vendor download sites. The malicious actors may use similar-sounding domain names, certificates, and hijacked designs and contents to coerce the victims into thinking that they are accessing the legitimate address.
Another way that the threat may spread is through infected payloads — the use of various files that are infected with virus code. A popular example is the malicious document which can take any form: presentations, rich text files, spreadsheets and databases. Once they are opened by the victims a notification message will pop up asking the target users to enable the built-in scripts. If this is done the virus infection will follow. The other popular technique is the inclusion of the code in application installers. They are malicious copies of legitimate setup files of popular end-user programs that have been modified with the Efdc ransomware code.
Ransomware files are also popularly spread by fake user profiles — they can post to community forums or social media accounts. The criminals can utilize both fake or stolen identities to increase the number of infected users.
In certain cases, the criminals may also be distributed via malicious browser plugins — additions to the most popular web browsers that are advertised as useful. The plugins are uploaded to the official repositories and often make use of fake or hijacked user reviews and developer credentials. Once they are installed by the users they will execute their built-in instructions that in many cases leads to the Efdc ransomware virus infection in the end.
Impact of .еfdc Files Virus
The ransomware virus dubbed Efdc has been identified as an iteration of the notorious STOP ransomware. Like its predecessors, among which is the recently found .puma virus, Efdc is designed to encrypt valuable files with a combination of two sophisticated cipher algorithms.
In order to reach data encryption stage, Efdc ransomware virus first interferes with basic system settings. The whole process is triggered by a payload file which could land on the device as a code embedded in a document, image, or other well-known file format or as a part of corrupted freeware installer. The other spread methods mentioned in the previous paragraph are also valid.
In the beginning of the attack, this iteration of STOP ransomware is likely to establish additional malware files and objects on the device. By doing this, it becomes able to continue with the successful contamination of various system settings and target data.
Changes implemented by the ransomware could affect some registry keys stored in the Registry Editor. Among the affected registry keys could be the Run and RunOnce. By adding its malicious values under these keys, Efdc becomes able to manipulate their functionalities. This, in turn, results in the automatic execution of its malicious files on each system start.
After all target system components are infected, Efdc crypto virus activates an inbuilt encryption module that is set to utilize a combination of two strong cipher algorithms AES and RSA. With the help of these ciphers, the ransomware implements significant changes to the code of target files and renders them inaccessible. Unfortunately, Efdc is a threat that could encrypt almost all types of files that are used for the storage of valuable data like:
- Archives
- Backups
- Databases
- Images
- Videos
- Music
Following encryption, all corrupted files could be recognized by the extension .еfdc as it is appended to their original names. In order to extort a ransom payment from the ransomware drops a file named _readme.txt and displays it on the screen. Here is what its content states:

Apparently, hackers attempt to trick you into paying them a ransom of $980 in Bitcoin or $490 if you pay within 72 hours after the infection is a fact. Beware that ransom payment does not guarantee the recovery of your .еfdc files. So be advised to check the guide below for tested alternative data recovery approaches.
Remove Efdc Ransomware Virus and Restore PC
Please note that paying the requested ransom fee to cyber criminals does not really solve your problem with Efdc crypto virus. In fact, you only encourage hackers to continue spreading ransomware of this kind. Instead, you must remove the threat immediately, and only then look for optional ways to recover your data.
WARNING! Manual removal of Efdc ransomware ransomware virus requires being familiar with system files and registries. Removing important data accidentally can lead to permanent system damage. If you don’t feel comfortable with manual instructions, download a powerful anti-malware tool that will scan your system for malware and clean it safely for you.
