Cryptobyte Ransomware

Cryptobyte Ransomware Description

The Cryptobyte Ransomware is a ransomware Trojan that has been distributed through spam email attachments since April 2017. The Cryptobyte Ransomware is a variant of CryptXXX and BTCWare, with some updated elements. These ransomware Trojans have been around since March 2016. The Cryptobyte Ransomware is designed to target computers running the Windows operating system (Windows 7 and later, both int heir 32-bit and 64-bit versions). The Cryptobyte Ransomware may be delivered through text documents that contain corrupted scripts, which download and install the Cryptobyte Ransomware on the victim's computer.

How the Cryptobyte Ransomware Carries out Its Attack

The Cryptobyte Ransomware uses a combination of the AES and RSA encryptions to make the victim's files inaccessible completely. Once the Cryptobyte Ransomware encrypts the files, they become unreadable and will show up as blank icons. The Cryptobyte Ransomware will mark the affected files with the file extension '.[btc.com@protonmail.ch].cryptobyte' and '.[no.xm@protonmail.ch].cryptobyte' markers, depending on the exact version of the Cryptobyte Ransomware. The Cryptobyte Ransomware will encrypt a wide variety of file types, which may include the following:

.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.

The Cryptobyte Ransomware delivers its ransom note in an INF file named '#_HOW_TO_FIX.inf. This ransom note contains the following message:

Dealing with the Cryptobyte Ransomware Infection

Unfortunately, it may not be possible to decrypt files that have been encrypted in the Cryptobyte Ransomware attack. Considering this, the best protection against the Cryptobyte Ransomware and similar attacks is to have file backups on offline devices or the cloud (not synchronized with the main computer to prevent the backups themselves from becoming encrypted). Malware experts do not advise computer users to pay the Cryptobyte Ransomware ransom. The con artists may not keep their promise to restore the affected files, often asking for more money, ignoring the ransom payment, or encrypting the files again after a short time. Furthermore, paying the Cryptobyte Ransomware ransom finances these people's activities, allowing them to carry out additional attacks against computer users. The Cryptobyte Ransomware attacks can be prevented with the help of a security program, which can intercept the Cryptobyte Ransomware infection before it encrypts the victim's files. It is also a necessary move to educate computer users in the correct handling of email attachments and how to recognize known email tactics since this is the primary way in which the Cryptobyte Ransomware and most ransomware Trojans are distributed. A combination of safe browsing and handling of email and a strong security program can help stop more ransomware attacks and, in the case of a successful infection, having file backups will nullify the effects of the attack and allow easy recovery completely.
