What is SpyHunter ransomware? And how does it implement its attack?
SpyHunter ransomware is a dangerous threat that can lock valuable files in a computer and leave them inaccessible. It also happens to be the latest variant of GarrantyDecrypt ransomware and seems to copy the name of a legitimate anti-spyware program even though there is no relation.
Once SpyHunter ransomware infiltrates the system, it connects it to a remote server. After that, it creates and downloads more malicious files and places them on system folders. Following the infiltration, it proceeds to make modifications in the Windows Registry by modifying some existing registry keys like RunOnce as well as create new ones to allow it to run on every system boot automatically. Just like its predecessors, SpyHunter ransomware also employs two modules namely, data harvesting and stealth protection modules.
The first module is used to gather information from the computer and use it for the second module which is the one that bypasses any security programs installed in the system that could interfere with the attack. It then scans the computer for files with specific formats such as:
.3g2, .3gp, .7z, .accdb, .aes, .ARC, .asc, .asf, .asm, .asx, .avi, .backup, .bak, .bat, .brd, .bundle, .c, .cgm, .cmd, .cpp, .crt, .cs, .csproj, .csr, .csv, .db, .dbf, .dch, .der, .dip, .djvu, .doc, .docb, .docm, .docx, .dot, .dotx, .dwg, .edb, .eml, .flv, .frm, .gif, .gpg, .gz, .htm,.html, .hwp, .Iay6, .ibd, .iso, .jar, .jpeg, .jpg, .js, .jse, .key, .lay, .lbd, .log, .m2ts, .max, .mdf, .mdp, .mid, .midi, .mkv, .mml, .mov, .mp3, .mp4, .mpeg, .mpg, .msg, .myd, .myi, .nef, .ocx, .odg, .odp, .odp, .ods, .odt, .onetoc2, .ost, .otg, .otp, .ott, .PAQ, .pas, .pdf, .pern, .pfx, .php, .png, .pot, .potm, .potx, .ppam, .pps, .ppsm, .ppsx, .ppt, .pptm, .pptx, .pst, .pub, .py, .pyc, .pyd, .pyo, .rar, .raw, .rm, .rpa, .sb2, .sch, .sh, .sin, .sldm, .sldx, .slk, .snt, .sql, .sql, .sqlite3, .sqlitedb, .stc, .std, .sti, .stw, .suo, .svg, .swf, .sxc, .sxd, .sxi, .sxm, .sxw, .tar, .tar, .tbk, .tiff, .txt, .uop, .uot, .vb, .vbe, .vbproj, .vbs, .vcd, .vdi, .vdmk, .vmx, .vob, .vsd, .vsdx, .wks, .wma, .wncry, .wrav, .xdata, .xlc, .xlm, .xls, .xlsb, .xlsm, .xlsx, .xlt, .xltm, .xltx, .xlw, .zip
Based on the sample files gathered in the active campaign on SpyHunter ransomware, just like other variants of GarrantyDecrypt ransomware, this one does not use a typical encryption algorithm since it uses a random private RSA 348 key and then proceeds to use RSA 4096. It then adds the .spyhunter suffix to every compromised file. After the encryption is completed, it releases a file named “$HOWDWCRYPT$.txt” which contains the following ransom note:
“All your files are encrypted by Enigma SpyHunter5s!
