What is MADA ransomware? And how does it implement its attack?
MADA ransomware is a crypto-malware designed to encrypt files. It is another variant of the notorious Jigsaw ransomware which keeps on spawning variants every now and then. MADA ransomware, according to researchers, is quite identical to Monument ransomware and Payms ransomware. And once it is able to get a hold of the targeted system, it will start to scan the system looking for files to encrypt. Based on the analysis done on this Jigsaw variant, it is found to be targeting files with these extensions:
.1c, .3fr, .accdb, .mp3, .mrw, .nef, .ai, .arw, .cdr, .cer, .cfg, .config, .cr2, .csv, .db, .dbf, .dcr, .der, .dng, .doc, .docm, .dwg, .dxf, .dxg, .eps, .erf, .gif, .mp4, .iso, .jpe, .jpeg, .jpg, .bac, .mk, .nrw, .odb, .ode, .odm, .odp, .ods, .odt, .orf, .kdc, .mef, .p12, .p7b, .p7c, .pdd, .pdf, .pef, .pem, .lnk, .mdb, .mdf, .pfx, .php, .pptx, .htm, .psd, .pst, .ptx, .r3d, .rar, .html, .indd, .raw, .rtf, .rw2, .rwl, .sql, .sr2, .srf, .docx, .srw, .tif, .wb2, .png, .ppt, .pptm, .wma, .wpd, .wps, .x3f, .crt, .crw, .css, .xlk, .xls, .bay, .bmp, .xlsb, .xlsm, .xlsx, .zip
MADA ransomware uses the AES encryption cipher in encrypting files and appends the .LOCKED_BY_pablukl0cker extension on the encrypted files. For instance, a file named image101.jpg will become image101.jpg.LOCKED_BY_pablukl0cker. Once the encryption is completed, it opens a program window containing the following text:
“OOPS! YOUR FILES ARE CRYPTED BY MADA RANSOMWARE!!!
Your documents, photos, videos etc.
And after 72 hours, all your files will be removed permanently !!!
But there is nothing to worry about it will only happen when you fly in a fuck
Every hour I delete one randomly selected file and delete it permanently!!!
I can not recover such a file anymore, even after making the payment!!!
You will lose only a few files for the first 24 hours.
but the next day a few hundred, the third day, a few thousand, etc …
If you turn off your computer or try to shut me down, I will fire again.
I automatically remove 1000 files permanently for trying to recommend me in a fuck!!!
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 BITCOIN!!!
