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 Advanced System Repair to eradicate Malware for you (it should cut down the time to about 15 minutes).
What is B2DR ransomware? And how does it carry out its attack?
B2DR ransomware is a new crypto-malware discovered recently. It is designed to lock important files in a targeted computer. It carries out its attack using a malicious payload that once executed, will make modifications in the system. These modifications involve creating and downloading other malicious files in the system to make sure that nothing will interfere with its nefarious attack. In addition, it also alters the registry to achieve persistence.
After it’s done establishing itself into the system, B2DR ransomware will begin its scanning process to look for certain file types. According to security experts, it may target 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
Following data encryption, B2DR ransomware will make its presence known by delivering a ransom note in a file named “readme.txt” that states:
“All your files are encrypted.
Ask how to restore your files by email email@example.com
Use only gmail.com, yahoo.com, protonmail.com.
Messages are written by other mail services we cannot get.
!!!With any changes to the encrypted files, do not forget to backup files!!!
Your ID: ***”
The cyber crooks even offer to decrypt three files that are not more than 2 MB in size to entice users into paying the ransom. But mind you, paying the ransom is not a good idea. Cybercrooks may demand a huge ransom amount from you and despite the offer of decrypting three files, that still does not make this crypto-malware close to being trustworthy so it’s best if you stir clear of it and make its removal a priority then look for other alternative ways to recover your encrypted files.
How does B2DR ransomware spread its malicious payload?
B2DR ransomware employs malicious spam emails in spreading its malicious payload where they attach infected files. These infected files are mostly documents with macro scripts which are used to execute some command to download and install B2DR ransomware into the system. These documents are usually disguised as receipts, invoices, and other seemingly important documents so you need to beware of such tactics used by cyber crooks these days.
