What is LockCrypt ransomware? And how does it implement its attack?
LockCrypt ransomware is a new ransomware Trojan that is being actively distributed over hacked remote desktop services. This new ransomware variant was detected in the last week of February 2018. When installed, LockCrypt ransomware implements its attack by scanning the computer for files to encrypt. Once it founds the files, it will begin its encryption process using the base64 encryption strategy and append the .1btc extension to the encrypted file names. Following data encryption, it drops its ransom note in a file named Restore Files.txt that provides detailed information of what has happened to the victim’s files. Here’s the full content of the ransom note:
“Your ID xxx
All your files have been encrypted due to a security problem with your PC. If you want to restore them, write us to the e-mail support: [email protected] or [email protected]

As you can see, the cyber crooks did not mention how much then ransom is but they did mention that the ransom will depend on how fast the victim manages to contact them right after the attack. Note that this is merely a tactic to get its victims to reach out to them right away so that they can demand a big ransom and this is something you must not do. Not only is it a waste of time but you might also end up losing a big amount of money for nothing. Unfortunately, there is no free decryptor available yet to decrypt the encrypted files of LockCrypt ransomware. But you can use whatever backup copy you have of the affected files on your computer.
How does LockCrypt ransomware spread its malicious payload?
AS pointed out early on, this new version of LockCrypt ransomware spreads through remote desktop services where developers of this ransomware login to the targeted computer and install the ransomware themselves. To prevent this kind of attack, where hackers login to a computer and execute the ransomware, it is recommended to lock the service correctly and that the PC running remote desktops services should be placed behind VPNs to block any kind of unauthorized access of those who don’t have VPN accounts connected to your network.
