Especially since you have a chance to restore your documents, photos and music for free using utilities such as ShadowExplorer and PhotoRec.
We suggest you to get rid of Blind virus as quickly as possible, until the presence of the ransomware has not led to even worse consequences. You need to follow the few simple steps below that will help you to completely remove Blind ransomware virus from your computer as well as recover encrypted files, using only few free utilities.
What is Blind ransomware
Blind ransomware is a variant of crypto viruses (malicious software that encrypt personal files and demand a ransom). It affects all current versions of Windows operating system such as Windows XP, Windows Vista, Windows 7, Windows 8, Windows 10. This ransomware virus uses a strong encryption algorithm to eliminate the possibility of brute force a key which will allow to decrypt encrypted files.
When the ransomware virus infects a PC, it uses system directories to store own files. To run automatically whenever you turn on your system, Blind ransomware creates a registry entry in Windows: sections HKCU \ Software \ Microsoft \ Windows \ CurrentVersion \ Run, HKCU \ Software \ Microsoft \ Windows \ CurrentVersion \ RunOnce, HKCU \ Software \ Microsoft \ Windows \ CurrentVersion \ Run, HKCU \ Software \ Microsoft \ Windows \ CurrentVersion \ RunOnce.
Immediately after the launch, the ransomware scans all available drives, including network and cloud storage, to determine which files will be encrypted. The ransomware virus uses the file name extension, as a method to define a group of files that will be subjected to encrypting. Encrypted almost all types of files, including common as:
.avi, .wm, .upk, .d3dbsp, .wotreplay, .docx, .ods, .kdc, .rw2, .bkp, .xlgc, .odp, .cas, .arw, .wmv, .sav, .jpe, .rb, .wri, .xlsx, .wpd, .x3f, .wp7, .big, .wbk, .sb, .itm, .7z, .xdl, .svg, .zdc, .vpp_pc, .odb, .indd, .t12, .mp4, .db0, .dxg, .bc7, .wbmp, wallet, .zi, .wpb, .xld, .crw, .lrf, .1, .x, .xlsb, .xyp, .pdd, .wmd, .pst, .mdbackup, .srw, .3fr, .p7c, .wmo, .xmmap, .xar, .wmf, .yml, .csv, .eps, .der, .cr2, .wp, .mcmeta, .wpw, .3dm, .rar, .xx, .ff, .cdr, .xy3, .xmind, .desc, .hkx, .dcr, .wbc, .zw, .p7b, .bsa, .xls, .gho, .wps, .zabw, .mdf, .tor, .re4, .r3d, .wpa, .cfr, .wpl, .erf, .xyw, .sid, .sidd, .wdb, .xml, .psk, .snx, .layout, .apk, .wav, .xll, .docm, .xlsm, .z3d, .ztmp, .dba, .fos, .zdb, .wmv, .jpeg, .dazip, .blob, .itl, .pptx, .wcf, .psd, .rtf, .gdb, .qic, .x3d, .wp6, .accdb, .hkdb, .wgz, .hplg, .lbf, .2bp, .arch00, .tax, .xbdoc, .wdp, .wma, .xdb, .zip, .forge, .wbz, .bar, .asset, .ai, .w3x, .wbm, .m2, .bay, .zip, .xwp, .mov, .bik, .wsd, .m3u, .sql, .mef, .crt, .wn, .z, .map, .raf, .wsh, .ibank, .xxx, .das, .xlsx, .sum, .ntl, .x3f, .xls, .pdf, .sis, .ncf, .mpqge, .odm, .m4a, .nrw, .pfx, .wpt, .txt, .orf, .wma, .rgss3a, .0, .zif, .sr2, .sie, .wsc, .iwd, .vcf, .pkpass, .mddata, .rofl, .cer, .kdb, .png, .vfs0, .xlsm, .mlx, .litemod, .yal, .pem, .wp5, .vtf, .ybk, .rim, .py, .mrwref, .dng, .ptx, .webp, .raw, .odt, .itdb, .syncdb, .dmp, .y, .bkf, .wpe, .wot, .iwi, .hvpl, .sidn, .epk, .flv, .wpd, .wps, .wpg
Once a file is encrypted, its extension changed to .[firstname.lastname@example.org].blind. Next, the ransomware virus creates a file called “How_Decrypt_Files.hta”. This file contain tutorial on how to decrypt all encrypted files. An example of the tutorial is:
All your files have been encrypted!
All your files have been encrypted due to a security problem with your PC. If you want to restore them, write us to the e-mail email@example.com 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.
Free decryption as guarantee
Before paying you can send us to 3 files for free decryption. the total size of file must be less than 1Mb (non archived), and files should not contain valuable information (databases, backups, large excel sheets, etc.)
How to obtain Bitcoins
The easiest way to buy bitcoins is LocalBitcoins site. You have to register, click “Buy bitcoins”, and select the seller by payment method and price.
Also you can find other places to buy Bitcoins and beginner guide here.
The Blind ransomware actively uses scare tactics by giving the victim a brief description of the encryption algorithm and showing a ransomnote on the desktop. It is trying to force the user of the infected machine, do not hesitate to pay a ransom, in an attempt to recover their files.
How to decrypt .blind files
Currently there is no available solution to decrypt [firstname.lastname@example.org].blind files, but you have a chance to recover encrypted files for free. The ransomware repeatedly tells the victim that uses very strong hybrid encryption with a large key. What does it mean to decrypt the files is impossible without the private key. Use a “brute forcing” is also not a method because of the big length of the key. Therefore, unfortunately, the only payment to the creators of the Blind ransomware virus entire amount requested – the only method to try to get the decryption key and decrypt all your files.
There is absolutely no guarantee that after pay a ransom to the developers of the Blind ransomware, they will provide the necessary key to decrypt your files. In addition, you must understand that paying money to the cyber criminals, you are encouraging them to create a new ransomware virus.
