What is AnonCrack ransomware? And how does it perform its attack?

AnonCrack ransomware is a new file-encrypting Trojan which mainly targets Spanish users based on its ransom note written in Spanish. This new ransomware is created based on HiddenTear – an open source platform used by tons of cyber criminals in creating ransomware infections. This was discovered on October 12, 2017 and is being delivered on vulnerable computers using a fake software. According to researchers this particular fake software is named as Paypal Money Sender V2.0.
Interestingly, majority of this ransomware’s target users are running 32-bit Intel 386 processors. It hides under the fake Paypal Money Sender V2.0 program. On its infiltration, the ransomware immediately scans the computer’s drives for the following file formats so that it can encrypt them.
.3gp, .7z, .apk, .avi, .bmp, .cdr, .cer, .chm, .conf, .css, .csv, .dat, .db, .dbf, .djvu, .dbx, .docm, ,doc, .epub, .docx .fb2, .flv, .gif, .gz, .iso .ibooks,.jpeg, .jpg, .key, .mdb .md2, .mdf, .mht, .mobi .mhtm, .mkv, .mov, .mp3, .mp4, .mpg .mpeg, .pict, .pdf, .pps, .pkg, .png, .ppt .pptx, .ppsx, .psd, .rar, .rtf, .scr, .swf, .sav, .tiff, .tif, .tbl, .torrent, .txt, .vsd, .wmv, .xls, .xlsx, .xps, .xml, .ckp, .zip, .java, .py, .asm, .c, .cpp, .cs, .js, .php, .dacpac, .rbw, .rb, .mrg, .dcx, .db3, .sql, .sqlite3, .sqlite, .sqlitedb, .psd, .psp, .pdb, .dxf, .dwg, .drw, .casb, .ccp, .cal, .cmx, .cr2.
It encrypts the files using the AES 256 encryption algorithm and then adds the .crack file extension on the compromised files. After that, AnonCrack ransomware deletes all the Shadow Volume copies of the encrypted files to make sure that its victims won’t be able to recover them. This only shows that this ransomware is quite dangerous as without any decryption key, it would be hard for users to recover inaccessible files. Aside from that, this ransomware also drops a mscoree.dll file. Afterwards, the AnonCrack ransomware changes the computer Desktop’s background image which contains the ransom note written in Spanish:
“Tu computador ha sido hackeado y encriptado by ANONCRACK …!

  1. Realiza el pago de 30 USD ha esta direccion bitcoin : 1CvWhugm6QbHisVvhyRuKn81kQgVVs4ov8
  2. Envia una captura del pago y nombre de tu PC ha este correo: [email protected]
  3. Una vez verificado tu pago, te enviaremos la KEY de DESENCRIPTACION
  4. Disfruta de tus archivos personales

Tus amigos ANONCRACK”
Aside from the wallpaper, the ransomware also drops a file named PAGO.txt which also contains the message written above. Once again, paying the ransom is not necessary and would only be a waste of your time and money as these cyber criminals are not exactly known to keep their words. It would be best if you remove the ransomware first from your PC to prevent it from damaging more of your files and for the meantime use your files’ backup copies to recover them while waiting for security experts to come up with a free decryptor.
How is AnonCrack ransomware disseminated online?
The ransomware spreads as a fake PayPal app – Paypal Money Sender V2.0 – which is likely distributed in forums and malicious websites. Take note that there is no such thing as Paypal Money Sender V2.0. An app like this does not exist. According to researchers, this fake software is also likely to spread in spam emails. Cyber criminals often disguise these kinds of spam emails as something urgent to trick users into downloading and opening the attachment. To avoid AnonCrack ransomware, you must be cautious about downloading apps or software from third party app stores or free sharing sites as some of these sites can’t be trusted and are often exploited by cyber crooks.
