What is LockDown Ransomware

LockDown is a file-encrypting software created to earn money on unprotected users. The virus acts using AES+RSA algorithms to set up strong encryption on stored data and appends .LockDown extension. Many kinds of data will be changed according to this example 1.mp4.LockDown. After the encryption is done, LockDown creates a text note (HELP_DECRYPT YOUR FILES) containing ransom instructions.

LockDown Ransomware
Oops All Of your important files were encrypted Like document pictures videos etc..
Don't worry, you can return all your files!
All your files, documents, photos, databases and other important files are encrypted by a strong encryption.
How to recover files?
RSA is a asymmetric cryptographic algorithm, you need one key for encryption and one key for decryption so you need private key to recover your files. It’s not possible to recover your files without private key.
The only method of recovering files is to purchase an unique private key.Only we can give you this key and only we can recover your files.
What guarantees you have?
As evidence, you can send us 1 file to decrypt by email We will send you a recovery file Prove that we can decrypt your file
Please You must follow these steps carefully to decrypt your files:
Send $460 worth of bitcoin to wallet: 3arsmgdD3tukQ7T7Wk9wZGCk24mU7XRR12
after payment,we will send you Decryptor software
contact email: help_recouver@protonmail.com
Your personal ID: [redacted]

Users are said that only a private key held by cybercriminals can lead to successful data decryption. To obtain it, victims have to send approximately 460$ worth of Bitcoin to the attached wallet. Although extortionists ostensibly prove their integrity by allowing users to decrypt 1 file for free, we still advise against paying the ransom, because there is a risk that swindlers will not provide recovery tools eventually. For now, there are no official tools that could guarantee 100% file decryption. You can recover your files using an external backup or following the article below to try other decryption methods.

Do not open them because they can be a cover for malicious software like LockDown Ransomware. Ransomware can also be spread via backdoors, keyloggers, web-injects, unprotected RDP configuration, and countless others. Remember that any interaction with unknown content can be dangerous, so make sure you sort out trusted from unreliable resources. We have gathered a couple of great security tools to help you avert unintentional interaction with potentially dangerous content below.
