How to Terminate B2DR (email@example.com) (firstname.lastname@example.org) Ransomware (Crypto-Malware/Ransomware)
Malware may reinstall itself multiple times if you don't delete its core files. This may require tracking down dozens of files in different locations.
We recommend downloading Restoro to eradicate Malware for you (it should cut down the time to about 15 minutes).
What is B2DR (email@example.com) ransomware? And how does it execute its attack?
B2DR (firstname.lastname@example.org) ransomware is a file-encrypting malware and is a new variant of B2DR (email@example.com) ransomware, hence the name. This new variant was released in June 2018 and follows the other two previous variants of B2DR (firstname.lastname@example.org) that appends the .email@example.com and .firstname.lastname@example.org extensions.
Based on the analysis done by security experts, nothing much has changed in this new variant, save for the extensions it uses in marking the files it encrypts. During the infiltration, the crypto-malware is launched in the system using a malicious executable file. This executable file is also responsible for connecting the infected computer to a remote C&C server where it downloads more malicious files. These other malicious files are dropped in the system folder and programmed to stop any programs installed in the system from impeding its attack. These files are also set to modify the Windows Registry, particularly the RunOnce sub-keys to make sure that B2DR (email@example.com) ransomware can run on every system boot. After these alterations, it will begin to look for 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
As usual, just like other variants of B2DR, this one also uses the AES 256 encryption algorithm in encrypting the targeted files listed above. Once it completes encrypting them, it adds the .firstname.lastname@example.org extension to each one of the files. It then releases its ransom note contained in a text file named “ScrewYou.txt” that states:
“Your files were encrypted with AES-256.
