Ordinal ransomware is a new rasnsomware Trojan created using the infamous HiddenTear open source platform. This was first discovered on October 20, 2017 and targets regular PC users. As of the moment, it is identified by multiple security programs as:

  • Ransom.Hiddentear.A.F8C468CD

  • malicious_confidence_100% (W)

This crypto-malware does not show any peculiar traits. On the other hand, it downloads a particular wallpaper from https://i.imgur.com during its infiltration. According to security experts, this new ransomware is similar to ViiperWare rasnomware and AnonCrack ransomware which are all built on the same open source platform. However, this particular ransomware can also be downloaded on the Dark Web for free and it is next to impossible in finding out who is behind this new threat.
During its infiltration, Ordinal ransomware scans the drives in your PC looking for files to encrypt. After that, it starts the encryption process using the AES 256 military-grade cipher and adds the .Ordinal extension on each of the affected files. It then proceeds to deliver its ransom note which is loaded on the screen using the Notepad program and is named as READ ME To Get Your Files Back.txt and contains the following text:
Follow the instructions to unlock your data
All your files have been encrypted with AES-256 Military Grade Encryption
Your files have been encrypted, the only way to recover your files is to pay the fee. Once you have paid the fee all your files will be decrypted and return to normal.

Once you have sent the required fee to the Bitcoin address send an email with your Identification key (without this we can’t help you). It may take 12-24 hours to us to respond.

Amount to Send: 1.00 BTC
Contact [email protected]
The cyber crooks behind Ordinal ransomware demands a payment if 1 BTC which is approximately $5732 in exchange for the decryption program you need to restore your encrypted files by contacting the given address which is at [email protected].
