What is Hc6 ransomware? And how does it implement its attack?

Hc6 ransomware is a vicious file-encrypting threat designed to make them unreadable to its victims. Its attacks were first discovered on November 8, 2017. It seems like this crypto-malware is an independent encryption ransomware project and is not part of a larger ransomware group just like Hidden Tear or EDA2. It aims to target computer networks and once a computer connected to a network is infected, hc6 ransomware continues to cause havoc in the network of computers further infecting more users in the process. After its successful infiltration, it begins to scan the entire drive of the computer looking for files to encrypt. According to security experts, it encrypts the following file extensions:
.001, .3fr, .3gp, .7z, .ARC, .DOT, .MYD, .MYI, .NEF, .PAQ, .SQLITE3, .SQLITEDB, .accdb, .aes, .ai, .apk, .arch00, .arw, .asc, .asf, .asm, .asp, .asset, .avi, .bar, .bay, .bc6, .bc7, .big, .bik, .biz, .bkf, .bkp, .blob, .bmp, .brd, .bsa, .cas, .cdr, .cer, .cfr, .cgm, .class, .cmd, .cpp, .cr2, .crt, .crw, .csr, .css, .csv, .d3dbsp, .das, .dazip, .db0, .dbf, .dbfv, .dch, .dcr, .der, .desc, .dif, .dip, .djv, .djvu, .dmp, .dng, .doc, .docb, .docm, .docx, .dotm, .dotx, .dwg, .dxg, .epk, .eps, .erf, .esm, .exe, .ff, .fla, .flv, .forge, .fos, .fpk, .frm, .fsh, .gdb, .gho, .gpg, .hkdb, .hkx, .hplg, .htm, .html, .hvpl, .hwp, .ibank, .ibd, .icxs, .indd, .itdb, .itl, .itm, .iwd, .iwi, .jar, .java, .jpeg, .jpg, .js, .kdb, .kdc, .key, .kf, .lay, .lay6, .layout, .lbf, .ldf, .litemod, .log, .lrf, .ltx, .lvl, .m2, .m3u, .m4a, .map, .max, .mcgame, .mcmeta, .mdb, .mdbackup, .mddata, .mdf, .mef, .menu, .mid, .mkv, .mlx, .mml, .mov, .mp3, .mpeg, .mpg, .mpqge, .mrwref, .ms11 (Security copy), .ncf, .nrw, .ntl, .ocx, .odb, .odc, .odm, .odp, .ods, .odt, .orf, .otg, .ots, .ott, .p12, .p7b, .p7c, .pak, .pas, .pdd, .pdf, .pef, .pem, .pfx, .php, .pkpass, .pl, .png, .ppam, .ppsm, .ppsx, .ppt, .pptm, .pptx, .psd, .psk, .pst, .ptx, .py, .qcow2, .qdf, .qic, .r3d, .raf, .rar, .raw, .rb
Take note that the extensions listed above are only a fraction of the files it encrypts as Hc6 ransomware encrypts dozens of file extensions in its wake. During the encryption, it encrypts the targeted files using a combination of AES 256 CBC and SHA 256 encryption algorithms. It then proceeds to mark each file using the .fucku extension. After that, it drops its ransom note in a file named recover_your_fies.txt which is full of grammatical errors. It reads:
As usual, paying the ransom is not a solution. In fact security experts are strongly against this as there is no guarantee that the crooks will really give you the encryption key to recover your files and besides there is already a free decryptor available online which you can use if you happen to be one of the unlucky victims of Hc6 ransomware.
How does Hc6 ransomware spread its malicious payload?
Hc6 ransomware spreads its malicious payload by hacking into unsecure and poor remote desktop services. Once the crooks get a hold of a computer in a network, it will download and install the malicious payload for Hc6 ransomware to begin its attack.
