Malware Category: Ransomware
Katyusha Ransomware is a Crypto-Ransomware virus first seen in October, 2018. Katyusha Ransomware targets PCs running Windows OS and requesting 0.5BTC ransom. Every file that has been encrypted will have its extension changed to: .katyusha. Unfortunately, still, there is no way of decrypting the files encrypted by Katyusha Ransomware.
The distribution of Katyusha Ransomware is related to installing different third-party toolbars, all kinds of free software, files from P2P networks and torrents, random clicking on ads, pop-up windows, banners, or even downloading attached files from your personal e-mail inbox or other file sharing applications, bogus flash player and fake video software for viewing online content.
When running, Katyusha Ransomware will start encrypting certain types of files stored on local or mounted network drives using a RSA-2048 bit public-key cryptography, with the private key stored only on a control server. The virus will encrypt files with the following extensions:
.jpg, .jpeg, .raw, .tif, .gif, .png, .bmp, .3dm, .max, .accdb, .db, .dbf, .mdb, .pdb, .sql, .dwg, .dxf, .cpp, .cs, .h, .php, .asp, .rb, .java, .jar, .class, .py, .js, .aaf, .aep, .aepx, .plb, .prel, .prproj, .aet, .ppj, .psd, .indd, .indl, .indt, .indb, .inx, .idml, .pmd, .xqx, .xqx, .ai, .eps, .ps, .svg, .swf, .fla, .as3, .as, .txt, .doc, .dot, .docx, .docm, .dotx, .dotm, .docb, .rtf, .wpd, .wps, .msg, .pdf, .xls, .xlt, .xlm, .xlsx, .xlsm, .xltx, .xltm, .xlsb, .xla, .xlam, .xll, .xlw, .ppt, .pot, .pps, .pptx, .pptm, .potx, .potm, .ppam, .ppsx, .ppsm, .sldx, .sldm, .wav, .mp3, .aif, .iff, .m3u, .m4u, .mid, .mpa, .wma, .ra, .avi, .mov, .mp4, .3gp, .mpeg, .3g2, .asf, .asx, .flv, .mpg, .wmv, .vob, .m3u8, .dat, .csv, .efx, .sdf, .vcf, .xml, .ses, .qbw, .qbb, .qbm, .qbi, .qbr , .cnt, .des, .v30, .qbo, .ini, .lgb, .qwc, .qbp, .aif, .qba, .tlg, .qbx, .qby , .1pa, .qpd, .txt, .set, .iif, .nd, .rtp, .tlg, .wav, .qsm, .qss, .qst, .fx0, .fx1, .mx0, .fpx, .fxr, .fim, .ptb, .ai, .pfb, .cgn, .vsd, .cdr, .cmx, .cpt, .csl, .cur, .des, .dsf, .ds4, .drw, .eps, .ps, .prn, .gif, .pcd, .pct, .pcx, .plt, .rif, .svg, .swf, .tga, .tiff, .psp, .ttf, .wpd, .wpg, .wi, .raw, .wmf, .txt, .cal, .cpx, .shw, .clk, .cdx, .cdt, .fpx, .fmv, .img, .gem, .xcf, .pic, .mac, .met, .pp4, .pp5, .ppf, .nap, .pat, .ps, .prn, .sct, .vsd, .wk3, .wk4, .xpm, .zip, .rar.
Katyusha Ransomware will create _how_to_decrypt_you_files.txt and put a shortcut to it in every folder where a file was encrypted. Those files contain instructions explaining how to pay the ransom. For the victims to pay the ransom, the virus asks them to contact the developers at the following e-mail: email@example.com.
When Katyusha Ransomware is initiated on the computer, it will inject deep into the system infecting Explorer.exe and svchost.exe, modify the registry to start with Windows, and disable the Automatic Repair feature. Once active, it will start the process of encrypting files. These types of ransomware are very hard to detect. Nevertheless, the virus will show its presence after the encryption finishes.
Katyusha Ransomware will not just encrypt files and block your computer, it will also collect valuable information that will be sent to the control servers. Such software could lead to more malware coming into your computer and even cause a loss of data. Such threats are not to be underestimated!
