What is UselessFiles ransomware? And how does it carry out its attack?
UselessFiles ransomware is a file-encrypting virus that was first spotted on the first day of May 2018. This ransomware is created to encrypt victims’ files to leave them inaccessible. It uses the .uselessfiles extension on each one of the files it encrypts and demands a ransom to its victims in exchange for the decryption software or encryption key.
As soon as it infects a targeted system, it will download and install more malicious files to help it carry out its attack in the system. During its attack, it will search for certain file types in the system. UselessFiles ransomware is known to encrypt images, documents, videos, database, and other user-generated files such as:
.txt, .doc, .docx, .xls, .index, .pdf, .zip, .rar, .css, .lnk, .xlsx, .ppt, .pptx, .odt, .jpg, .bmp, .png, .csv, .sql, .mdb, .sln, .php, .asp, .aspx, .html, .xml, .psd, .bk, .bat, .mp3, .mp4, .wav, .wma, .avi, .divx, .mkv, .mpeg, .wmv, .mov, .ogg, .java, .csv, .kdc, .dxg, .xlsm, .pps, .cpp, .odt, .php, .odc, .log, .exe, .cr2, .mpeg, .jpeg, .xqx, .dotx, .pps, .class, .jar, .psd, .pot, .cmd, .rtf, .csv, .php, .docm, .xlsm, .js, .wsf, .vbs, .ini, .jpeg, .gif, .7z, .dotx, .kdc, .odm, .xll, .xlt, .ps, .mpeg, .pem, .msg, .xls, .wav, .odp, .nef, .pmd, .r3d, .dll, .reg, .hwp, .7z, .p12, .pfx, .cs, .ico, .torrent, .c
Once it finds these files, it will apply a custom AES cipher in encrypting them. Once it completes data encryption, a “B.bmp” files is set as a custom desktop background image. Moreover, it also delivers its ransom note that states:
