How to remove EduCrypt (Virus Removal Guide)
EduCrypt is a very unusual version of open source Hidden Tear ransomware. Most ransomware infections will encrypt the files on your computer, restrict access to your machine, and demand a payment in order to recover your files; However, this ransomware does not demand a payment and instead tries to teach victims a lesson on being safe and aware online.
Once EduCrypt ransomware is installed it will encrypt a limited amount of files on your computer and add an .isis extension to the file name of files that it encrypts (example: test.png would become test.png.isis). The ransomware has a limited set of folders that it encrypts, it targets a small amount of different file extensions, and it does not communicate with a Command & Control server like most ransomware does.
%UserProfile%\Desktop %UserProfile%\Downloads %UserProfile%\Documents %UserProfile%\Pictures %UserProfile%\Music %UserProfile%\Videos
.txt, .exe, .doc, .docx, .xls, .index, .pdf, .zip, .rar, .css, .lnk, .xlsx, .ppt, .pptx, .odt, .jpg, .bmp, .png, .csv, .sql, .mdb, .sln, .php, .asp, .aspx, .html, .xml, .psd, .bk, .bat, .mp3, .mp4, .wav, .wma, .avi, .divx, .mkv, .mpeg, .wmv, .mov, .ogg
When the ransomware has finished encrypting files, it will add a note file called README.txt on your desktop. The note contains a link to a decryptor and information on what happened to the encrypted files. The hidden file that it references is located at %UserProfile%\Documents\DecryptPassword.txt and contains the password that can be used to decrypt your files.
The universal password that can be used to decrypt your files is HDJ7D-HF54D-8DN7D. This password is the same for everyone affected by EduCrypt ransomware.
