What is jCandy ransomware? And how does it implement its attack?
jCandy ransomware a new crypto-malware designed to encrypt important files in the targeted computer and extorts victims to pay a ransom to get them back. jCandy is a new variant of the open source platform, Hidden Tear, which is known to have spawned countless numbers of ransomware infections since 2015. And since jCandy ransomware is a Hidden Tear variant, it seeks to encrypt the files with the following file formats:
.txt, .doc, .docx, .xls, .xlsx, .pdf, .pps, .ppt, .pptx, .odt, .gif, .jpg, .png, .db, .csv, .sql, .mdb.sln.php, .asp, .aspx, .html, .xml, .psd, .frm, .myd, .myi, .dbf, .mp3, .mp4, .avi, .mov, .mpg, .rm, .wmv, .m4a, .mpa, .wav, .sav, .gam, .log, .ged, .msg, .myo, .tax, .ynab, .ifx, .ofx, .qfx, .qif, .qdf, .tax2013, .tax2014, .tax2015, .box, .ncf, .nsf, .ntf, .lwp
The encryption algorithm it uses during the encryption is undoubtedly AES since its based on Hidden Tear. However, security experts determined that jCandy uses a combination of AES and RSA ciphers which means that its encryption algorithm is strong that would make it hard for its victims to recover the encrypted files using the alternative way to recover them which is through their shadow volume copies. After the encryption jCandy ransomware drops a text file named JCANDY_INSTRUCTIONS.txt which contains the ransom note. It also opens a program window labeled as jCandy. Both the ransom note and the program window contain the same message that reads as follows:
YOUR FILES HAVE BEEN LOCKED!
We have encrypted ALL your important files!
We have NOT deleted ANY files. Your files have been LOCKED!
lf you would like access to your files you will need to purchase $200 USD worth of BITCOIN
and have it sent to this bitcoin address below.
After the payment is received your files will be decrypted and this program will delete itself.
You have 48 hours to send the payment and have your files unlocked-
If you fail to do so. your files will be DELETED
~ Kind Regards, jCandy”
No matter how impossible it seems to recover the encrypted files, you should not consider paying the ransom as you will end up losing your money, not to mention that it would only motivate cyber crooks to create more ransomware infection. Bear in mind that cyber crooks can’t be trusted and they are not really known to keep their promises. The best thing to do for now is to use whatever backup copies you have of the encrypted files until a free decryptor is developed.
How is jCandy ransomware disseminated?
jCandy ransomware spreads using various methods – one of which is through spam emails. In a spam email, cyber criminals attach a corrupted file such as macro-enabled document or an executable file which is responsible for installing jCandy into the targeted computer. They often disguise the email as something sent by well-known company or group to trick users into downloading and opening the attachment. Aside from that, jCandy also spreads in fake software updates, file bundles that contains a concealed malicious software and rogue downloads.
