Kryptonite RBY Ransomware

The Kryptonite RBY Ransomware is an encryption ransomware Trojan. These threats are used to take the victims' files hostage, demanding a ransom payment from the victim. To take the victim's files hostage, threats like the Kryptonite RBY Ransomware use strong encryption methods, which make the victim's files inaccessible. It is crucial to take preventive measures against threats like the Kryptonite RBY Ransomware, especially having backup copies of all files.

Superman’s New Enemy

The Kryptonite RBY Ransomware, not to be confused with Kryptonite Ransomware, which appeared in June 2017, seems to be a standalone ransomware Trojan. That is to say that the Kryptonite RBY Ransomware does not seem to belong to a larger threat family, but an independent threat actor created it. The Kryptonite RBY Ransomware uses the executable file Kryptonite.exe and includes strings in its properties, which indicates that it is owned by 'RBY,' as well as the string 'Fuck Superman.' The Kryptonite RBY Ransomware seems to be poorly implemented and does not seem to carry out a full ransomware attack, (which involves not only encrypting the victim's files but also demanding a ransom payment). PC security researchers reported the Kryptonite RBY Ransomware on September 14, 2017.

How a Kryptonite RBY Ransomware Attack Affects Your Files

The Kryptonite RBY Ransomware may be a partial or unfinished threat, or it may simply have been a failed and abandoned ransomware Trojan. The Kryptonite RBY Ransomware fails to encrypt the victim's files and seems to crash when running in a test environment. The Kryptonite RBY Ransomware is meant to use a combination of the RSA 1024 and AES 256 encryptions, which will make the victim's files inaccessible. The Kryptonite RBY Ransomware will change the victim's desktop image and display a ransom note, as well as text referencing comics villains in its attack. The Kryptonite RBY Ransomware will encrypt various file types in its attack, generally looking for files that are user-generated (such as music, video, audio, and text files). The following are some examples of the file types that may be targeted by attacks like the Kryptonite RBY Ransomware:

.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 Kryptonite RBY Ransomware will demand a ransom payment after encrypting the victim's files. The Kryptonite RBY Ransomware displays the following note on the victim's computer:

'ATTENTION!
All the files on your disk were encrypted.'

The Kryptonite RBY Ransomware’s Ransom Demands

Ransomware Trojans like the Kryptonite RBY Ransomware will demand a ransom payment. However, PC security researchers have not observed any ransom demand associated with the Kryptonite RBY Ransomware. Furthermore, since its encryption routine seems ineffective, it seems that at this time the Kryptonite RBY Ransomware does not pose a significant threat and can be removed with the help of a reliable, fully updated anti-malware application easily. However, a new version of the Kryptonite RBY Ransomware may pop up at any moment, and encryption ransomware Trojans like this one are quite active and can attack at any time currently. Because of this, preventive steps should be taken, to ensure that your data is protected. The most effective step you can take to protect your data is to have reliable file backups. This helps recovery in case your files become encrypted by an attack like the Kryptonite RBY Ransomware.
