What is Happychoose file extension
.Happychoose file extension is a file extension that is used by the latest variant of GlobeImposter ransomware. ‘Happychoose’ variant is very similar in its characteristics to other variants of this ransomware. It also encrypts files, and then renames them, giving them a new filename consisting of their old and ‘.happychoose’ appended at the end. Criminals demand a ransom for a key-decryptor pair, which is necessary to unlock encrypted data.
What is Happychoose ransomware
Happychoose ransomware is one of the variants of the GlobeImposter ransomware. It appends the ‘.Happychoose’ extension to each file that it encrypts using a complex encryption mechanism. As its previous variants, it can use the same distribution methods (spam emails, adware, cracks, key generators and so on). Upon execution, Happychoose starts working in the background immediately. First of all, the virus configures the Windows so that it starts automatically every time the computer is turned on. Happychoose ransomware uses this mechanism to continue encrypting files if it was interrupted by turning off or restarting the computer. Further, the ransomware contacts its control server to send information about the infected computer and receive additional commands.
After all the preparatory steps are completed, Happychoose proceeds to the main thing, it begins to encrypt files. All files will be encrypted, regardless of where they are located, on the local disk or on a network-connected disk. That is, the contents of the following common file types can be encrypted:
.py, .xyp, .forge, .wps, .rw2, .ws, .sr2, .ntl, .flv, .arch00, .vdf, .nrw, .fos, .dazip, .pak, .xx, .der, .sav, .mcmeta, .wot, .bik, .pptm, .zip, .kf, .bsa, .xlsx, .zi, .eps, .wav, .wbk, .dcr, .docx, .r3d, .vcf, .xlsm, .wmo, .webp, .p7b, .tax, .xar, .mpqge, .wmd, .raf, .2bp, .yal, .lbf, .ods, .wpa, .zw, .litemod, .bkp, .iwd, .ff, .pdd, .wpe, .zif, .wma, .svg, .snx, .wbz, .vtf, .rb, .sie, .zip, .jpg, .sb, .wsh, .xlsx, .x, .itl, .desc, .css, .xdb, .p7c, .wotreplay, .y, .dba, .gdb, .wmv, .layout, .slm, .wdb, .xpm, .wpl, .wgz, .xxx, .xml, .dng, .doc, .0, .hkdb, .wp, .tor, .mov, .xbplate, .wdp, .mdbackup, .fpk, .sql, .xlsb, .blob, .jpeg, wallet, .ibank, .z3d, .psk, .1st, .map, .csv, .orf, .apk, .sis, .xld, .erf, .xwp, .bay, .pptx, .bc7, .ltx, .pst, .ptx, .rwl, .ncf, .big, .zdb, .webdoc, .wpw, .crt, .cdr, .3dm, .mddata, .sidn, .wsd, .odp, .z, .7z, .pdf, .xls, .yml, .xyw, .odm, .zdc, .hkx, .wbm, .accdb, .wri, .wp7, .x3f, .dwg, .itdb, .hvpl, .mef, .wpt, .bc6, .raw, .rofl, .ztmp, .ybk, .odt, .das, .iwi, .odb, .ppt, .pem, .wbc, .rgss3a, .sum, .indd, .wp5, .dmp, .mlx, .menu, .3ds, .3fr, .wm, .w3x, .ysp, .pfx, .wire, .rtf, .txt, .wp4, .mrwref, .esm, .re4, .wma, .dbf, .m4a, .wpb, .xbdoc, .qic, .epk, .xy3, .png, .t12, .mp4, .xmmap, .wpd, .mdf, .m2, .cer, .wpg, .docm, .x3f, .dxg, .psd, .lvl, .x3d, .js, .upk, .wp6, .xlgc, .xlk, .zabw, .wmv, .xf, .xll, .pef, .wbd, .t13, .srw, .odc, .d3dbsp, .1, .xmind, .gho, .qdf, .vpk, .wbmp, .p12, .xdl, .wb2, .xlsm, .wmf, .wps, .vfs0
When a file is encrypted, the ‘.happychoose’ extension is appened at the end of its name, that is, if you had a file called ‘document.docx’, then a file with the name ‘document.docx.happychoose’ will appear in its place. If you change the file name, just delete the appended extension, then nothing will change. The file will remain encrypted, and as before, this file will not be possible to open in the program with which it is associated.
The Happychoose ransomware creates a file with the name “Decryption INFO.html” on the infected computer. This file contains a message from the ransomware authors. The full text of this file is:
ALL YOUR FILES ARE ENCRYPTED!
ALL YOUR IMPORTANT DATA HAS BEEN ENCRYPTED.
To recover data you need decryptor.
To get the decryptor you should:
Send 1 test image or text file firstname.lastname@example.org or email@example.com.
In the letter include YOUR ID (look at the beginning of this document).
We will give you the decrypted file and assign the price for decryption all files
After we send you instruction how to pay for decrypt and after payment you will receive a decryptor and instructions We can decrypt one file in quality the evidence that we have the decoder.
Only firstname.lastname@example.org or email@example.com can decrypt your files
Do not trust anyone firstname.lastname@example.org or email@example.com
Do not attempt to remove the program or run the anti-virus tools
Attempts to self-decrypting files will result in the loss of your data
Decoders other users are not compatible with your data, because each user’s unique encryption key
Criminals use the files to demand ransom from the Happychoose ransomware victims. The ransom demand message said that the victim’s files are encrypted. The authors of the ransomware demand a ransom in exchange for a key and a decryptor. Attackers offer to decrypt one image or text file for free. Of course, decryption of one file cannot guarantee that, after paying the ransom, the victim will be able to recover files affected with the ransomware.
