Written by William Reddy

If you can’t open your photos, documents, or other files and also see the .ewdf extension on them, your system is definitely infected with Ewdf ransomware. It belongs to STOP/Djvu ransomware group

Ewdf ransomware ciphers personal files located on the victim’s PC with the extension “.ewdf” and after that generates the ransom note in each folder which contains encrypted files. The instructions are placed on the victim’s PC in the “readme.txt” file. Its activity is pretty much comparable to other variants of the same ransomware family: Zpps, Nnuz, Qlln.

Ewdf is file-encrypting ransomware that prevents regular access to your text files, Excel tables, videos and pics by ciphering them. It marks the ciphered files with the “.ewdf” extension. Then Ewdf ransomware adds a money ransom note (readme.txt) to each folder. In this note, you can see the instructions to pay the ransom ($490-$980 in Bitcoin) to a certain Bitcoin address. The AES-256 or RSA-1028 cipher it utilizes to encrypt the documents is not decryptable with contemporary computers. Even quantum computers that currently exist will spend hundreds of years to find the decryption key.

How dangerous is the Ewdf ransomware?

When Ewdf ransomware appears on your PC, it will examine your disks for photos, videos, and also important documents. It encrypt] all widespread file formats- .psd, .doc, .docx, .xls, .xlsx, .pdf, .jpeg, .png, et cetera. When these documents are found, the ransomware will cipher them and change their extension to “.ewdf” so that you understand what happened.

After the Ewdf ransomware ciphered the data on your PC, it will drop the last “readme.txt” file on the desktop. Besides the ransom transactioning instructions, the victims also see the emails to contact the crooks – helprestoremanager@airmail.cc and manager@mailtemp.ch.

How did the Ewdf ransomware get on my computer?

The Ewdf ransomware spreads by posting links to download hacked programs or games. Cybercriminals who distribute this ransomware are quite foxy, and aim to correspond with modern things. New games releases, new popular films – Ewdf developers make everything to get their victims on that. One of the most common strategies these burglars use is one-day websites with torrent downloading links. However, using the current news is not the single way these burglars use. Options that have already turned into standard, such as email spamming, are likewise common for STOP/Djvu ransomware spreading.

Malicious email spam

The example of email spamming that may lead to Ewdf ransomware injection

Avoiding this ransomware does not need a lot of effort. Considering the ordinary principles of PC hygiene will substantially reduce all dangers. Keep in mind that starting all documents you get on e-mail is not a great tactic. Even worse situation is to enable macros in Microsoft Office documents. But it is much better to stop the malware attack at the moment when you have just opened the email message. Checking the sender’s address can say a lot about what you can expect, and when you see the thing like “support@amazon.com”– it is likely a legitimate e-mail. At the same time, stuff that tries to appear like Amazon or FedEx delivery alert, but uses the email address of “amazonspurrot1363@gmail.com”– should make you be on the alarm. Above, you can see the example of such a message.

Illegal sources of different digital things require some extra explanation. Violating copyright law surely throws you to the possibility of being fined. However, utilizing torrent trackers or third-party websites to download “free” programs also exposes you to a wide range of malware. No one can regulate unidentified people that start the torrent seeding or publish the hacked program version on the website with pirated program.
