Dear Victim
The key data points of your network has been compromised,
and all of your university's critical data has been transferred to our secure systems
Positive News:
We are capable of fully restoring your systems and data.
If we come to an agreement, this incident will remain confidential between your organization and our team.
Our motivation is purely financial, and we do not align with any specific country or political ideology.
Terms and Conditions:
The ransom is 25k.
You must contact us within 24 hours; otherwise, we will publish an announcement  about the leak of your data.
You have 2 days to reach an agreement; If you fail to do so, your data will be published and the recovery tool destroyed.

Our reply may be treated as spam, so please make sure to check your spam/junk folder.

We know you have a backup system.
But your backup system is very outdated and does not have complete backups.
And we have deleted some of the backups.
Restoring data from the backup system will take several days and cannot be fully recovered.
The rational choice is to work with us,
which allows immediate data recovery,
and permanently eliminate the risk of data leaks.
We understand that you are a private university.
In the event that you do not agree with us,
confidential data related to your university will be sold or shared with those who are interested in this data.
Besides your university itself,
your employees and students could also fall victim.
This will severely damage your reputation.
It could even make headlines.
You can be sure that you will incur damages far exceeding the amount we are requesting from you should you decide not to agree with us.
What we offer in exchange for your payment:
Full decryption and restoration of systems and data following an incident, completed within 24 hours.
We guarantee that all recovered data will remain confidential and that all of your leaked data will be securely deleted from our servers after resolving the incident. We will provide a full deletion log.
Expert advice tailored to strengthen your IT infrastructure against future threats.
Useful tips that will help you:
Do not try to recover files yourself.
Do not modify encrypted files.
Do not use third party software to restore your data.
Again, just to be clear
