How dangerous is BandarChor virus?

BandarChor ransomware virus was first detected in 2014. More than one year later, in 2016, this virus still continues infecting PC users and encrypts their files with the help of the same, AES 256 encryption algorithm[1]. However, the updated version of BandarChor is capable of blocking new extensions, including e-wallet files by appending .BandarChor file extensions to them. According to PC security experts, the latest version of this ransomware can attack files with these extensions: .001 .ace .bup .bvd .cng .cryptra .dco .enx .fdp .jac .jbc .kbb .nba .pkey .rzx .safe .sde .sgz .sle .sme .vhd .wallet .wbb .wbcat .win. The email addresses which can be used to contact hackers and require a decoder for the encrypted files are Shigorin.Vitolid@gmail.com and help@decryptservice.info. However, we do NOT recommend dealing with hackers because you can be left with no money and no files. If you want to protect your important data, make sure you transfer it to external hard drives, USB sticks and similar places. Also, keep your browser up-to-date and install a reliable anti-spyware on your computer to prevent infiltration of this ransomware. If you need to remove BandarChor from the system, you should use Reimage.

It is known that the latest version of BandarChor ransomware spreads via malvertising technique[2] which relies on infected ads placed on adult sites. However, spam email messages that inform about issues, such as refunds, taxes, purchases, etc., have also been noticed in the distribution of this malware. Therefore, you need to be very careful with sites filled with adult content and avoid clicking ads that are displayed on them. In addition, do NOT open attachments of emails that you haven’t been waiting for. Spam email attachment that is involved in the distribution of this ransomware can be infected with a Trojan horse that works as an executable of the malware and launches it right after being clicked. However, it has also been reported that this threat uses Exploit Kits[3] to infiltrate the system unnoticed. They are placed on malicious websites and used to download ransomware to the system right after being clicked. If you think that you are infected, make sure you take care of BandarChor removal from your computer.
