What is Oblivion ransomware? And how does it execute its attack?
Oblivion ransomware, also referred to as “Scarab-Oblivion” ransomware, is a new variant of the Scarab ransomware. This new Scarab variant uses the .OBLIVION extension in marking the files it encrypts. This new variant enters the system in a typical way- via corrupted spam email attachments. As soon as it enters the system, it alters a couple of system settings to allow the crypto-malware to load itself in every Windows boot up. After that it will look for files to encrypt by scanning the entire drive of the infected system. According to security experts, it might encrypt files with these 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
After the encryption process, Oblivion ransomware appends the .OBLIVION extension to each one of the files and release a ransom note in a text file named “OBLIVION DECRYPTION INFORMATION.txt” containing this content:
“YOUR FILES ARE ENCRYPTED!
