Crypt6 Ransomware

The Crypt6 Ransomware is an encryption ransomware Trojan that PC security analysts observed on August 2, 2018. The Crypt6 Ransomware is a variant of a ransomware family first observed in February 2016. The Crypt6 Ransomware, like many other, similar threats, is being delivered to victims through the use of compromised spam email attachments. Because of this, it is important for computer users to take precautions when handling unsolicited email attachments and spam email content.

How the Crypt6 Ransomware Trojan can Affect Your Files

The Crypt6 Ransomware functions by taking the victims' files hostage, demanding a ransom payment to restore access to the victim's files. The Crypt6 Ransomware encrypts the victims' files using a strong encryption algorithm and marks any files compromised by the attack by adding the file extension 'css' to the end of the affected files' names. The Crypt6 Ransomware targets the user-generated files, which may include files with the following file extensions:

.ebd, .jbc, .pst, .ost, .tib, .tbk, .bak, .bac, .abk, .as4, .asd, .ashbak, .backup, .bck, .bdb, .bk1, .bkc, .bkf, .bkp, .boe, .bpa, .bpd, .bup, .cmb, .fbf, .fbw, .fh, .ful, .gho, .ipd, .nb7, .nba, .nbd, .nbf, .nbi, .nbu, .nco, .oeb, .old, .qic, .sn1, .sn2, .sna, .spi, .stg, .uci, .win, .xbk, .iso, .htm, .html, .mht, .p7, .p7c, .pem, .sgn, .sec, .cer, .csr, .djvu, .der, .stl, .crt, .p7b, .pfx, .fb, .fb2, .tif, .tiff, .pdf, .doc, .docx, .docm, .rtf, .xls, .xlsx, .xlsm, .ppt, .pptx, .ppsx, .txt, .cdr, .jpe, .jpg, .jpeg, .png, .bmp, .jiff, .jpf, .ply, .pov, .raw, .cf, .cfn, .tbn, .xcf, .xof, .key, .eml, .tbb, .dwf, .egg, .fc2, .fcz, .fg, .fp3, .pab, .oab, .psd, .psb, .pcx, .dwg, .dws, .dxe, .zip, .zipx, .7z, .rar, .rev, .afp, .bfa, .bpk, .bsk, .enc, .rzk, .rzx, .sef, .shy, .snk, .accdb, .ldf, .accdc, .adp, .dbc, .dbx, .dbf, .dbt, .dxl, .edb, .eql, .mdb, .mxl, .mdf, .sql, .sqlite, .sqlite3, .sqlitedb, .kdb, .kdbx, .1cd, .dt, .erf, .lgp, .md, .epf, .efb, .eis, .efn, .emd, .emr, .end, .eog, .erb, .ebn, .ebb, .prefab, .jif, .wor, .csv, .msg, .msf, .kwm, .pwm, .ai, .eps, .abd, .repx, .oxps, .dot

Unfortunately, the Crypt6 Ransomware uses a strong encryption algorithm, and the files compromised by the Crypt6 Ransomware attack are not recoverable without the decryption key, which the criminals hold in their possession. Once the Crypt6 Ransomware has encrypted a file, the victim will not be able to read its contents or open it with another application.

How the Criminals may Profit from Attacks Like the Crypt6 Ransomware

The Crypt6 Ransomware attack's main goal is to generate profits at the expense of computer users. The criminals can make money from infecting the victims' computers with the Crypt6 Ransomware by demanding a ransom payment from the victims. The Crypt6 Ransomware delivers a ransom note written in French. However, it is clear that the writer of the ransom note is not a native speaker since the ransom note is very poorly written. The Crypt6 Ransomware's ransom note is contained in a text file named 'READ_ME.txt,' which it will be drop on the affected computer's desktop. Victims of the Crypt6 Ransomware attack are asked to contact the criminals through the following email addresses: 'frthnfdsgalknbvfkj@outlook.fr,' 'frthnfdsgalknbvfkj@yahoo.com,' 'frthnfdsgalknbvfkj@gmail.com' and 'algerienmarocaine@outlook.fr.' PC users are advised to refrain from doing this and to, instead, take precautions against the Crypt6 Ransomware and similar threats.

Protecting Your Data from Threats Like the Crypt6 Ransomware

The Crypt6 Ransomware's damage can be fixed easily if its victim has file backups. Having file backups ensures that computer users are capable of recovering from the Crypt6 Ransomware attacks after an infection. Apart from file backups, good protection against threats like the Crypt6 Ransomware is to have a security application that is fully up-to-date installed on your computer. The combination of a good security program, file backups, and precautions when handling spam email and unsolicited email attachments can help computer users avoid infections such as the Crypt6 Ransomware.
