What is FUCKMEDADDY ransomware? And how does it execute its attack?

FUCKMEDADDY ransomware is a new variant of the infamous Jigsaw ransomware. This new variant was recently discovered in the second week of January 2018 and seems to be aimed at Polish-speaking users. It is known to use the name “DUPA” ransomware when it loads its ransom note. Once it is able to enter a targeted system, it will look for certain file extensions to encrypt. According to researchers, it may be files with the following extensions:
.3dm, .3g2, .3gp, .7zip, .aaf, .accdb, .aep, .aepx, .aet, .ai, .aif, .as, .as3, .asf, .asp, .asx, .avi, .bmp, .c, .class, .cpp, .cs, .csv, .dat, .db, .dbf, .doc, .docb, .docm, .docx, .dot, .dotm, .dotx, .dwg, .dxf, .efx, .eps, .fla, .flv, .gif, .h, .idml, .iff, .indb, .indd, .indl, .indt, .inx, .jar, .java, .jpeg, .jpg, .js, .m3u, .m3u8, .m4u, .max, .mdb, .mid, .mkv, .mov, .mp3, .mp4, .mpa, .mpeg, .mpg, .msg, .pdb, .pdf, .php, .plb, .pmd, .png, .pot, .potm, .potx, .ppam, .ppj, .pps, .ppsm, .ppsx, .ppt, .pptm, .pptx, .prel, .prproj, .ps, .psd, .py, .ra, .rar, .raw, .rb, .rtf, .sdf, .sdf, .ses, .sldm, .sldx, .sql, .svg, .swf, .tif, .txt, .vcf, .vob, .wav, .wma, .wmv, .wpd, .wps, .xla, .xlam, .xll, .xlm, .xls, .xlsb, .xlsm, .xlsx, .xlt, .xltm, .xltx, .xlw, .xml, .xqx, .xqx, .zip.
FUCKMEDADDY ransomware is designed to encrypt files using a custom AES 256 encryption algorithm. Right after it finishes the encryption, it will append the .FUCKMEDADDY extension on every encrypted file. It then opens a program window named “FUCKMEDADDY” which shows an image of a nude woman pouring water on herself, it also contains the following ransom message:
Your documents, photos, videos etc … And after 72 hours, all your files will be removed permanently !!! But you do not have to worry about it it will happen only when you fuck up. Every hour I remove one randomly selected file and delete it permanently !!! I can not recover such a file even after payment !!! For the first 24 hours you will lose only a few files but the next day a few hundred, the third day there will be several thousand, etc … If you turn off the computer or try to shut me down it restarts automatically and I delete 1000 files permanently for trying to fuck with me!!! Remember that even the best anti-virus is unable to recover encrypted files! If you have any questions, please contact us via e-mail [email protected] !!! Payment for decrypting files is only possible in BITCOINS !!! If you do not know how to buy bitcoins, visit www.4coin.pl !!!
Now make a choice !!! pay and recover your files, or say goodbye to them”
FUCKMEDADDY ransomware deletes the shadow volume copies of the encrypted files to make sure that its victims won’t be able to use the System Recovery feature in Windows to recover their encrypted files. This does not mean that you should go ahead and pay the ransom though. Remember that paying the ransom does not really guarantee anything so you might end up losing money for nothing. All you can do for now is to terminate FUCKMEDADDY ransomware from your PC before it can do further damage. Once its removal is completed, you use whatever backup copies you have of your affected files until a free decryptor is released by security experts.
How does FUCKMEDADDY ransomware spread its malicious payload?

Such email messages often pretend that they are from well-known companies and even make it look like it’s an urgent email to lure you in opening the email and downloading the malware-laden attachment.
