First discovered in November 2014, BandarChor has been infecting user PCs ever since, encrypting their files with a strong AES-256 cipher. The latest discoveries of this ransomware indicated that it uses an AES-256 encryption algorithm to scramble user files and make them un-openable, leaving the only option for decryption to be paying ransom money usually in BitCoin to the cyber-criminals. Either way, this is not advisable since a decryptor may soon be released for this virus and it may allow users to decode their files for free. In the mean-time, we strongly advise reading the instructions in this article and try alternative methods to restore your files.

After the files have been dropped on the computer of the infected user, BandarChor may begin its scanning operation. The virus goes down through every file and folder, except the key folders without which Windows can no longer function:
- %Program Files% and %Program Files (x86)%
- %System Volume Information%

After encryption, BandarChor Ransomware adds a file extension which includes a unique identifier plus its e-mail address:
Besides the main e-mail (firstname.lastname@example.org) the virus is also associated with other e-mail addresses, like:
After encryption, BandarChor adds an image, called fud.bmp which has its ransom message:
The cyber-criminals are not very extensive in their instruction to the user, instead, they ask to contact them for more instructions. This is most likely an invitation to the negotiation of the ransom payment. The cyber-criminals may offer the free decryption of one file as a guarantee which we strongly advise users to take advantage off. This is because some decryptors, like Kaspersky’s utilities, may successfully decode your files in case you place an original file and an encrypted file. This is one of the reasons why experts strongly advise to copy the encrypted files, delete the ransomware and use other methods to try and restore them instead of paying off cyber-crooks.
