What is GarrantyDecrypt ransomware? And how does it implement its attack?

GarrantyDecrypt ransomware is crypto-malware designed to lock important data in an infected machine. This dangerous cyber threat is kind of different from other threats of its kind since it terminates other malware that might be already running in the infected system right before it begins encrypting files.

GarrantyDecrypt Ransomware

Once it infects a computer, it drops its malicious payload in the system and connects it to a Command and Control server where it downloads several malicious components and places them in system folders. It may also make entries in the Windows Registry and modify existing ones so that it can automatically run on each time users start their computers. And as pointed out earlier, it terminates any other malware running in the system. After that, it scans the entire drive in the system in search of files with the following extensions.

.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 GarrantyDecrypt ransomware, it 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 .garrantydecrypt suffix to each one of the encrypted files. Once the encryption is completed, it releases a file named “#RECOVERY_FILES#.txt” which contains the following ransom note:

“All your files have been ENCRYPTED
Do you really want to restore your files?
Write to our email –
[email protected]
and tell us your unique ID
[redacted 0x200 bytes in base64]”

Do not, under any circumstance, contact the crooks behind GarrantyDecrypt ransomware, nor should you pay the ransom it may demand. In fact, it’s best if you cease any contact with these attackers and focus instead on restoring your encrypted files.
