.EXTE File Virus – More Information

Being a variant of the CryptoMix ransomware infections, this virus aims to perform multiple different types of activities on the computers infected by it. It all starts with it’s malicious loader type of file, whose primary purpose is to extract the payload of the .EXTE ransomware virus. Such loader may pretend to be:

Legitimate setup, uploaded online.
Legitimate document sent to you over the web (Word, .PDF, Excel).
A game crack or any other activation software uploaded on suspicious websites.
A web link or a button which causes a drive-by download when you click on it. Such are often spammed as comments or other suspicious messages. Sometimes they are featured in spam e-mails as well.

Once the victim opens the loader file of .EXTE ransomware, the virus does not waste any time and downloads it’s payload from the C2 sever of the cyber-criminals it connects to. The payload may be under different names and be located in the commonly targeted folders of Windows:

After the malicious files are dropped, the virus begins encrypting the files on the infected computer. It targets mainly files with the following file types:

→ .sql, .mp4, .7z, .rar, .m4a, .wma, .avi, .wmv, .csv, .d3dbsp, .zip, .sie, .sum, .ibank, .t13, .t12, .qdf, .gdb, .tax, .pkpass, .bc6, .bc7, .bkp, .qic, .bkf, .sidn, .sidd, .mddata, .itl, .itdb, .icxs, .hvpl, .hplg, .hkdb, .mdbackup, .syncdb, .gho, .cas, .svg, .map, .wmo, .itm, .sb, .fos, .mov, .vdf, .ztmp, .sis, .sid, .ncf, .menu, .layout, .dmp, .blob, .esm, .vcf, .vtf, .dazip, .fpk, .mlx, .kf, .iwd, .vpk, .tor, .psk, .rim, .w3x, .fsh, .ntl, .arch00, .lvl, .snx, .cfr, .ff, .vpp_pc, .lrf, .m2, .mcmeta, .vfs0, .mpqge, .kdb, .db0, .dba, .rofl, .hkx, .bar, .upk, .das, .iwi, .litemod, .asset, .forge, .ltx, .bsa, .apk, .re4, .sav, .lbf, .slm, .bik, .epk, .rgss3a, .pak, .big, wallet, .wotreplay, .xxx, .desc, .py, .m3u, .flv, .js, .css, .rb, .png, .jpeg, .txt, .p7c, .p7b, .p12, .pfx, .pem, .crt, .cer, .der, .x3f, .srw, .pef, .ptx, .r3d, .rw2, .rwl, .raw, .raf, .orf, .nrw, .mrwref, .mef, .erf, .kdc, .dcr, .cr2, .crw, .bay, .sr2, .srf, .arw, .3fr, .dng, .jpe, .jpg, .cdr, .indd, .ai, .eps, .pdf, .pdd, .psd, .dbf, .mdf, .wb2, .rtf, .wpd, .dxg, .xf, .dwg, .pst, .accdb, .mdb, .pptm, .pptx, .ppt, .xlk, .xlsb, .xlsm, .xlsx, .xls, .wps, .docm, .docx, .doc, .odb, .odc, .odm, .odp, .ods, .odt.

After encryption has completed, the EXTE virus adds it’s distinctive file extension and completely changes the names of your important files, so that they become no longer recognizable. This results in the following appearance of the files:

After doing so, the virus also drops it’s ransom note, which has the following content:

Hello!
Attention! All Your data was encrypted!
For specific information, please send us an email with Your ID number:
Exte1@msgden.net
Exte2@protonmail.com
Exte3@reddithub.com
We will help You as soon as possible.
