What is Krakatowis ransomware? And how does it carry out its attack?

Krakatowis ransomware is a crypto-virus created to encrypt files in an infected PC. It seems like the cyber crooks behind this ransomware threat are posing as the Fsociety group who released a couple of ransomware threats last year. As you can see in the image above, it appears that the theme used for this crypto-virus is inspired by the fictional hacker group which has the same name from the TV show known as Mr. Robot.

The moment it infiltrates a system, Krakatowis ransomware might make a couple of modifications in the Windows Registry so it can run on every system boot as well as launch or repress Windows processes. Krakatowis ransomware may target user-generated files during the encryption such as documents, database, images, video, audio, and other popular file types such as:

.txt, .doc, .docx, .xls, .index, .pdf, .zip, .rar, .css, .lnk, .xlsx, .ppt, .pptx, .odt, .jpg, .bmp, .png, .csv, .sql, .mdb, .sln, .php, .asp, .aspx, .html, .xml, .psd, .bk, .bat, .mp3, .mp4, .wav, .wma, .avi, .divx, .mkv, .mpeg, .wmv, .mov, .ogg, .java, .csv, .kdc, .dxg, .xlsm, .pps, .cpp, .odt, .php, .odc, .log, .exe, .cr2, .mpeg, .jpeg, .xqx, .dotx, .pps, .class, .jar, .psd, .pot, .cmd, .rtf, .csv, .php, .docm, .xlsm, .js, .wsf, .vbs, .ini, .jpeg, .gif, .7z, .dotx, .kdc, .odm, .xll, .xlt, .ps, .mpeg, .pem, .msg, .xls, .wav, .odp, .nef, .pmd, .r3d, .dll, .reg, .hwp, .7z, .p12, .pfx, .cs, .ico, .torrent, .c

After the encryption process, it will lock the screen of the computer. The locked screen will show the following ransom note:

“Krakatowis

Cheat ka pa boy? Pm moko sa code!

thewebcrawler77@gmail.com

Enter the Code to unlock:

32 letters code:

Unlock

fsociety.dat”

Some parts of the ransom note are written in what seems to be the Tagalog language. The ransom note asks the victims to contact the given email address for the code used to unlock the computer and recover the encrypted files. Although the cyber crooks behind this threat do not want any money that does not mean that you have to contact them. The most practical thing to do is to start the elimination of the ransomware first before it locks more important files.
