|Alpha, Alpha virus, Alfa||Ransomware||100 / 100 *WARNING – REMOVE IMMEDIATELY!|
Alpha ransomware is a malicious file encrypter developed by the same entity behind Cerber ransomware. Alpha ransomware will encrypt files, add .bin to the file extension name, and leave 2 ransom notes on the computer named README HOW TO DECRYPT YOUR FILES.HTML and README HOW TO DECRYPT YOUR FILES.TXT.
The ransom note contains information and instructions about how to obtain a individual private key to decrypt your files. However, in order to do so the malicious program wants you to purchase the key and a special “Alfa Decryptor” for an excessive price via Bitcoin. The website associated with Alpha ransomware claims that after 3 days the price of the decryptor will increase by 20%. Here’s an example of what the ransom note says:
Cannot you find the files you need? Is the content of the files that you looked for not readable? If you are reading this message it means the software "Alpha Ransomware" has been removed from your computer
When Alpha ransomware infects a computer it will scan all the local drives for certain file types. Once it locates a specific file with the right file extension it will encrypt the file and add a .bin extension to the encrypted file name. For example, botcrawl.png will be encrypted to the filename botcrawl.png.bin. Here are the types of files that Alpha ransomware encrypts:
.c, .h, .m, .ai, .cs, .db, .nd, .pl, .ps, .py, .rm, .3dm, .3ds, .3fr, .3g2, .3gp, .ach, .arw, .asf, .asx, .avi, .bak, .bay, .cdr, .cer, .cpp, .cr2, .crt, .crw, .dbf, .dcr, .dds, .der, .des, .dng, .doc, .dtd, .dwg, .dxf, .dxg, .eml, .eps, .erf, .fla, .flvv, .hpp, .iif, .jpe, .jpg, .kdc, .key, .lua, .m4v, .max, .mdb, .mdf, .mef, .mov, .mp3, .mp4, .mpg, .mrw, .msg, .nef, .nk2, .nrw, .oab, .obj, .odb, .odc, .odm, .odp, .ods, .odt, .orf, .ost, .p12, .p7b, .p7c, .pab, .pas, .pct, .pdb, .pdd, .pdf, .pef, .pem, .pfx, .pps, .ppt, .prf, .psd, .pst, .ptx, .qba, .qbb, .qbm, .qbr, .qbw, .qbx, .qby, .r3d, .raf, .raw, .rtf, .rw2, .rwl, .sql, .sr2, .srf, .srt, .srw, .svg, .swf, .tex, .tga, .thm, .tlg, .txt, .vob, .wav, .wb2, .wmv, .wpd, .wps, .no, .xlk, .xlr, .xls, .yuv, .back, .docm, .docx, .flac, .indd, .java, .jpeg, .pptm, .pptx, .xlsb, .xlsm, .xlsx
Alpha ransomware will also download 2 ransom notes in the Documents and Desktop folders called README HOW TO DECRYPT YOUR FILES.HTML and README HOW TO DECRYPT YOUR FILES.TXT. The ransom notes contain information about what happened to the files, links to the TOR payment sites, and a unique ID that must be used to login to the payment site. Two of the current TOR payment sites that this ransomware uses are http://alfadecrfgqkcw6m.onion and http://2uxzf2mxe23f3clc.onion.
The ransomware will also create an autorun for the malware executable file so that it will run every time Windows starts. The autorun is called MSEstl and the executable file can be found here: %UserProfile%\AppData\Roaming\Microsoft\Essential\msestl32.exe.
To make matters much worse, Alpha ransomware will delete the Shadow Volume Copies on your computer in order to make it impossible to recover unencrypted files this way.
At this time, there does not appear to be a working decryptor for this ransomware. It is not recommended to pay ransomware authors to decrypt your files. Instead you can try to use programs like Shadow Explorer or Recuva to restore encrypted or deleted files.
