This article provides information about a data locker ransomware dubbed .BI_D files virus that encrypts important files and demands a ransom payment. By the end of it, you will know how to remove the threat and how to restore .BI_D files.
The .BI_D files virus is a new variant of the LockCrypt ransomware. Its primary goal is to encrypt specific files stored on your computer and then ask you to pay a ransom for a decryption key that could revert back their code. The virus sets the .BI_D file extension to all encrypted files. A ransom note with information on how to pay the ransom is likely to appear on PC screen after encryption. If your computer has been infected by the .BI_D files virus, we advise you to read this article to learn more about this malware and then follow a step-by-step removal.

.BI_D Files Virus – Distribution
The infection with .BI_D files virus happens after its payload is started on the system. There are several methods known to be possibly used for its distribution. The most common one is via email spam messages that pose as legitimate companies, trustworthy websites, and governmental institutions. Such messages provide malicious file attachments and links to compromised web pages. The text is likely to provoke you to download and open an attached file or click and visit the presented web page. And in case that you do one of these actions you grant the ransomware access to your system unintentionally.
Another possible spread technique regards the installers of various freeware apps. Free apps are preferred by users. So malicious intenders often incorporate their malware into the installers of such apps and trick users into infecting their systems with it.
.BI_D Files Virus – Overview
The .BI_D files virus is reported to be a new variant of the LockCrypt ransomware. It is a threat that sneaks into computer systems with the primary purpose to corrupt files that store important information.
Before it triggers its built-in encryption module .BI_D files virus plagues various essential system settings to remain undetected by running security measures and ensure its persistent presence.
The infection process begins after the ransomware payload is started on the system. As the code of the payload may not be designed to complete the attack till its end, it may create additional malicious files and store them in the following folders:
Some of the malicious files are likely to access the Registry Editor – a database that stores information about all essential system settings. Run and RunOnce are among the sub-keys that are often affected by ransomware infections. This could be explained by the fact that they keep info about all processes that need to start on each system load. By exploiting their functionalities .BI_D files virus could automatically execute its malicious files whenever the system is started.
At the end of the attack it drops a ransom note file called Restore Files.txt. When it appears on the PC screen victims could see the following text:
Your personal id – E3pgw1ofS2
Warning: all your files are infected with an unknown virus.
To decrypt your files, you need to contact at email@example.com.
The decoder card is received by bitcoin.
You can buy bitcoins from the following links://blockchain.info/wallet
Do not try to restore files your self, this will lead to the loss of files forever
You can send us 2-3 encoded files.
And attach to the letter a file from the folder c:\Windows\DECODE.KEY for testing, we will return them to you for FREE
.BI_D Files Virus – Encryption Process
It is known that this new version of LockCrypt ransomware is utilizing a combination of two highly complex cipher algorithms to encrypt target files. With the help of AES-256 and RSA-2048 .BI_D files virus transforms the original code of predefined types of files and then generates a unique decryption key. As the threat belongs to LockCrypt ransomware family it is likely to encrypt all files that have one of the following extensions:
→.incpas, .mp4, .pab, .st6, .sas7bdat, .wmv, .backup, .drf, .ibank, .3ds, .odg, .cer, .tif, .cs, .dotx, .7z, .png, .bak, .ibz, .db3, .pbl, .3fr, .dxf, .nk2, .bkp, .mdf, .svg, .xlm, .3dm, .pct, .java, .pot, .sxi, .ibd, .sxw, .pspimage, .ppt, .kbx, .ppsm, .ndd, .txt, .pdb, .say, .backupdb, .fla, .swf, .asx, .accdt, .mp3, .ycbcra, .erf, .cr2, .pfx, .potx, .qby, .sqlite, .blend, .class, .pat, .odp, .gray, .qbw, .tib, .thm, .htm, .mos, .rm, .key, .std, .tlg, .lua, .pst, .sqlitedb, .grey, .cdr4, .dc2, .ce1, .ps, .tex, .eml, .xlam, .pages, .st8, .jar, .st7, .potm, .sdf, .db-journal, .pcd, .aspx, .rwl, .kpdx, .fmb, .xlr, .gry, .kc2, .oil, .moneywell, .xlk, .sti, .accdr, .oth, .c, .xml, .nd, .mdb, .pem, .erbsql, .bpw, .ffd, .ost, .pptm, .dwg, .zip, .qbm, .cdx, .des, .dng, .pdd, .cfp, .nyf, .cgm, .sldm, .xla, .odf, .raf, .crw, .mef, .raw, .x11, .nsd, .fff, .design, .dcs, .ptx, .al, .ns2, .bik, .back, .accdb, .nwb, .cpi, .ads, .odt, .sqlite3, .docm, .drw, .pl, .nx2, .fpx, .rdb, .otp, .msg, .accde, .agdl, .php, .csv, .py, .rtf, .ach, .sda, .ddd, .asf, .dotm, .cmt, .h, .hbk, .xlsx, .s3db, .tga, .wav, .iif, .dxb, .sql, .db, .sd0, .bgt, .djvu, .jpg, .doc, .craw, .mpg, .sxd, .kdc, .jpeg, .psafe3, .flac, .dtd, .act, .qba, .vob, .cdrw, .eps, .bkf, .mdc, .rar, .mov, .cdf, .m4v, .ab4, .bank, .pps, .cib, .dot, .dgc, .exf, .flv, .xlsb, .ddrw, .adb, .srw, .plc, .csh, .xls, .fxg, .otg, .pas, .xlt, .indd, .rwz, .xltx, .apj, .stw, .xltm, .orf, .ott, .qbb, .max, .cls, .obj, .docx, .dcr, .cdr3, .qbx, .pdf, .nef, .ots, .srt, .ddoc, .rat, .phtml, .m, .dbx, .nxl, .avi, .p12, .awg, .dbf, .ns3, .mmw, .prf, .wallet, .rw2, .jin, .odc, .qbr, .ppsx, .ns4, .wpd, .wps, .nsh, .dxg, .fhd, .dac, .wb2, .nrw, .odb, .ait, .jpe, .odm, .sldx, .fdb, .acr, .war, .oab, .sxc, .cpp, .r3d, .hpp, .asm, .st5, .stx, .xis, .dds, .xlsm, .p7c, .cdr5, .3g2, .mrw, .sr2, .html, .cdr, .idx, .st4, .bdb, .kdbx, .nsg, .der, .ods, .myd, .nop, .ppam, .pptx, .yuv, .xlw, .mfw, .nsf, .csl, .php5, .p7b, .crt, .asp, .srf, .jsp, .cdr6, .sxm, .iiq, .3gp, .ce2, .arw, .bay, .ai, .sxg, .psd, .3pr, .fh, .pef, .x3f, .sik, .bpp, .vmdk, .spi, .bup, .cvt, .bb, .fkc, .tjl, .dbk, .swp, .fb, .vib, .dtb, .bke, .old, .bkc, .jou, .rpb, .abk, .sav, .bkn, .tbk, .fbw, .vrb, .spf, .bk, .sbk, .umb, .ac, .vbk, .wbk, .mbk
After encryption corrupted files have two extensions appended at the end of their names. First one is associated with the ID number given to each infected users so it is unique. The other one is fixed and it is .BI_D. Eventually, the pattern used for renaming encrypted files is .id-
For now, security researchers find its decryption impossible. But don’t even think to rush into paying the ransom to hackers. The analysis of .BI_ID files virus’s samples reveal the fact that if the ransomware is not running in an admin system mode it fails to save the specific decryption key. This means that even hackers may not have a working decryption solution. So if you want to prevent being tricked once again make sure to try all you can do by yourself before considering a ransom payment.
Remove .BI_D Files Virus and Restore Data
The removal of the so-called .BI_D files virus demands a bit of technical experience and ability to recognize characteristics of malware files. And there is no doubt that you should remove this nasty threat from the infected PC as soon as you detect it. Below you could find how to do it step by step. Beware that ransomware has highly complex code that could plague not only your files but your whole system. So as recommended by security researchers you need to utilize an advanced anti-malware tool for its complete removal. Such tool will keep your system protected against devastating threats like .BI_D files virus as well as all other kinds of malware in future.
