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

LockCrypt ransomware, also known as .mich file virus as it appends the .mich extension to its encrypted files, is a file-encrypting virus which was first discovered on December 2017. By the looks of it, it’s now back with a new and improved version that keeps on initiating brute-force attacks via Remote Desktop Services. Once it is able to gain access to the targeted PC, it will look for various kinds of files to encrypt which according to security experts are files containing these 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

These listed file types are only half of what LockCrypt ransomware can encrypt which makes it different and more dangerous than a typical ransomware infection. Once it finds the files it’s looking for, it will begin the encryption process and append the .mich extension or the .lock or .1btc extensions to the encrypted files. Following data encryption, LockCrypt ransomware delivers its ransom note that contains the following content:

“All your files have been encrypted due to the security problem with your PC. If you want to restore them, write us to the e-mail support: enigmax_x@aol.com or enigmax_x@bitmessage.ch

Write this ID in the title of your message

In case of no answer in 24 hours write us to these e-mails support: enigmax_x@aol.com or enigmax_x@bitmessage.ch

You have to pay for decryption in Bitcoins. The price dependson how fast you write to us.”
