Eliminating Cammora Ransomware (Crypto-Malware/Ransomware)

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

Cammora ransomware is one of the latest crypto-virus discovered recently. It is also a new variant of GarrantyDecrypt ransomware. This new ransomware strain uses the .cammora suffix in marking the files it encrypts. Once it infiltrates a targeted computer, Cammora ransomware will initiate a series of modifications in the system. It starts by connecting to a remote server where it downloads its other components and places them on several system folders. These components allows the crypto-virus to launch or repress system processes.
Using these components, it also employs a data harvesting module which gathers information from the system. The obtained information is processed and used for the stealth protection module which allows the crypto-virus to bypass security programs, virtual hosts, antivirus programs and sandbox environment that may interrupt the attack. To make its removal difficult, Cammora ransomware also alters some entries in the Windows Registry, allowing it to carry out its attack automatically in every system boot. Once it achieved in modifying essential system settings, Cammora ransomware will begin scanning the system for 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
After it encrypt its targeted files, using a sophisticated encryption algorithm, it adds the .cammora extension on each one of the compromised files and opens a text file named “#RECOVERY_FILES#.txt” which states:
“All your files have been encrypted!
Now you should send us email with your personal identifier.
This email will be as confirmation you are ready to pay for decryption key.
You have to pay for decryption in Bitcoins. The price depends on how fast you
write to us.
After payment we will send you the decryption tool that will decrypt all your
files.
Contact us using this email address
[email protected]
And tell us your unique ID
[redacted 0x200 bytes in base64]”
