Please help to decrypt my files

Recommended Posts

I recommend uploading a copy of the ransom note along with an encrypted file to ID Ransomware so that you can verify which ransomware you are dealing with:

You can paste a link to the results into a reply if you would like one of our experts to review them.

This is GlobeImposter 2.0:

Unfortunately there is no known way to decrypt files that have been encrypted by GlobeImposter 2.0 without first obtaining the private key from the criminals who made/distributed the ransomware.

Some people do have luck negotiating a lower price for the ransom.

There are also companies that offer their services to assist you with that. Coveware is the only one I can think of off the top of my head, and is one of the few that is honest about the fact that they are negotiating with the criminals for you.

 

Note: I would believe that GlobeImposter 2.0 is usually installed on a system that is compromised by brute forcing an RDP (Windows Remote Desktop) password. In case that is what happened here, I'll paste some information below that can help you prevent this from happening again:

First I recommend temporarily disabling all port rules in your firewall (closing all open ports) until you can do a full audit of your firewall configuration and determine which ports need to remain open. There are some basic recommendations below to help get you started with the port audit.

If you are managing a company network, then some form of IPS/IDS is highly recommended to monitor the network for intrusions. If you already have such a system in place, then I recommend a full audit of any rules you have configured to make sure that the device is providing adequate monitoring. It is also recommended to have someone with penetration testing experience verify that the IPS/IDS is properly alerting when there are intrusion attempts.

Also, quickly change all passwords on any workstations and/or servers that are connected to the same network as the compromised system. Also be sure to change passwords on any online accounts, as well as any routers or switches (or other devices that have network-accessible administration functions).

I recommend that every account have a different password, that passwords be no shorter than 25 characters and be made up of a random combination of uppercase letters, lowercase letters, numbers, and symbols. Obviously passwords like that are difficult (if not impossible) to remember, so a password manager may be required in order to aid in managing passwords. KeePass is probably the simplest password manager, and stores password databases locally instead of on some "cloud" server. If something capable of automatically filling in passwords (or sharing passwords between multiple devices/users) is necessary then there are reasonable passwords managers from LastPass, bitwarden, 1Password, Dashlane, etc. Note that unlike KeePass, these password managers work as extensions added to web browsers (or apps on mobile phones), and they store password databases online.

When auditing your firewall configuration and preparing to reopen ports, I recommend never opening ports globally unless absolutely necessary. I also recommend requiring anyone who needs access to sensitive services (RDP, Windows Networking, etc) to connect to the network via a VPN so that you don't have to open ports for those services in the firewall, and then only open the VPN port in the firewall for IP addresses that need access to it. If someone who needs access has a dynamic IP, then many firewalls these days support something like Single Packet Authorization or Port Knocking to dynamically open ports for unknown IP addresses.
