What is MauriGo ransomware? And how does it implement its attack?

MauriGo ransomware is a new ransomware threat being operated by an unknown group of hackers. It is a typical ransomware infection that uses the .encrypted extension after encrypting sensitive data on the infected computer. At the time of writing, there is no other information about the cyber crooks behind this crypto-malware but it was determined that the initial release of this ransomware was on April last year and now it’s back with a new and improved version.

This file-encrypting malware follows a set of hardcoded instructions set to make the file recovery hard for its victims. These hardcoded instructions involve deleting the shadow volume copies of the files. Meaning to say, it will be hard for users to recover their encrypted files without any decryption software or the decryption key.

MauriGo starts to implement its attack by scanning the entire drive of the affected PC searching for certain files that contains the following extensions:

.3gp, .7z, .apk, .avi, .bmp, .cdr, .cer, .chm, .conf, .css, .csv, .dat, .db, .dbf, .djvu, .dbx, .docm, ,doc, .epub, .docx .fb2, .flv, .gif, .gz, .iso .ibooks,.jpeg, .jpg, .key, .mdb .md2, .mdf, .mht, .mobi .mhtm, .mkv, .mov, .mp3, .mp4, .mpg .mpeg, .pict, .pdf, .pps, .pkg, .png, .ppt .pptx, .ppsx, .psd, .rar, .rtf, .scr, .swf, .sav, .tiff, .tif, .tbl, .torrent, .txt, .vsd, .wmv, .xls, .xlsx, .xps, .xml, .ckp, .zip, .java, .py, .asm, .c, .cpp, .cs, .js, .php, .dacpac, .rbw, .rb, .mrg, .dcx, .db3, .sql, .sqlite3, .sqlite, .sqlitedb, .psd, .psp, .pdb, .dxf, .dwg, .drw, .casb, .ccp, .cal, .cmx, .cr2

After the encryption, MauriGo ransomware appends the .encrypted extension to each one of the files and drops a ransom note named READ_TO_DECRYPT.txt that states:

 “The important files on your computer have been encrypted with military grade AES-256 bit encryption.

Your documents, videos, images and other forms of data are now inaccessible, and cannot be unlocked without the decryption key.

This key is currently being stored on a remote server.
