The best defensive strategy
to protect yourself from malware and ransomware (crypto malware) infection is a comprehensive approach
to include prevention. Make sure you are running an updated anti-virus and anti-malware product, update all vulnerable software, use supplemental security tools with anti-exploitation features
capable of stopping (preventing) infection before it can cause any damage, close/disable Remote Desktop Protocol (RDP)
if you do not need it and routinely backup your data
...then disconnect the external drive when the backup is completed. If you must use RDP, the best way to secure it is to either whitelist IP's on a firewall or not expose it to the Internet. Put RDP behind a firewall, only allow RDP from local traffic, setup a VPN to the firewall, use an RDP gateway
, change the default RDP port (TCP 3389
) and enforce strong password policies
, especially on any admin accounts or those with RDP privileges.

Unfortunately, there is no known method
to decrypt files encrypted by Rapid Ransomware. Demonslay335
explains the encryption process (it generates an RSA-1024 pair per run, and encrypts the private key of that with a hard-coded RSA-2048 public key
Demonslay335 also advised he has a decrypter for victims who have paid the ransom and received the criminal's key
...send him a PM with a link to the decrypter
they supplied you, and he can extract the private key to try with his decrypter. However, be aware that...
The malware handles large files differently, and their decrypter doesn't work with them. I'm still trying to factor for this in my own decrypter (which still requires the criminal's key).
Without the master private RSA key that can be used to decrypt your files, decryption is impossible. Your best option is to restore from backups
, try file recovery software
or backup/save your encrypted data as is
and wait for a possible solution at a later time. Ignore all Google searches which provide links to bogus and untrustworthy removal/decryption guides.
There is an ongoing discussion in this topic where victims can post comments, ask questions and seek further assistance. Other victims have been directed there to share information, experiences and suggestions.
Rather than have everyone with individual topics, it would be best (and more manageable for staff) if you posted any more questions, comments or requests for assistance in the above support topic discussion...it includes experiences by experts, a variety of IT consultants, end users and company reps who have been affected by ransomware infections. To avoid unnecessary confusion, this topic is closed.
