My leadership has a meeting scheduled with the board on Monday afternoon. Before that meeting, is there any cost breaks that you could provide us? This event has had a significant impact on our company.
13:46
10% discount for you and we close the deal.
15:09
Ok, I will provide this to my leaders and I will be back in touch on Monday afternoon.

Our leadership wants this to come to an end for both of us so we can get back to normality. They would like to offer $39,250 with all fees included. This would include the decryptor with any assistance we may need with it, proof that all our data has been removed from your systems and deleted with the promise not to ask for any additional money for anything after payment is received, a detailed explanation on how you got into our systems, and the promise to never attack us again. Please accept this offer so we can move on.
20:33
Are you seriously? This is an unacceptable offer. We will not even turn our heads in your direction for such a meager amount. Increase it.
20:36
We also want to remind you that you have a lot of critical data, a lot of personal data of your employees and customers, copies of passports and driver's license ([redacted] and many others), their SSN, DOB, addresses and phone numbers, your NDA, confidential agreements, financial documents and other documents can be used for bad purposes, loans, etc. Darknet users know how to do this. Therefore, we suggest you to think better and make the worthy offer.
16:36
What is meager to you, is not to us. Since this event we are struggling to get operational and have experienced tremendous losses. Leadership is prepared to offer $44,990 with all fees included. This would include the decryptor with any assistance we may need with it, proof that all our data has been removed from your systems and deleted with the promise not to ask for any additional money for anything after payment is received, a detailed explanation on how you got into our systems, and the promise to never attack us again. Please consider this offer as we are trying to get our business back operational.
17:18
We are ready to help restore all your systems and files to their original state very quickly, but the minimum amount we can accept is $150k. Less payment is not possible. Therefore, tell your manager if he wants to make a deal, then he look for this amount. If not, then further negotiations are pointless.
17:43
Leadership is prepared to accept your offer of $150,000 with all fees included. This would include a working decryptor with any assistance we may need with it, proof and assurance that all our data has been removed from your systems, deleted, not copied or transferred elsewhere, and with the promise not to ask for any additional money for anything after payment is received, a detailed explanation of why we were targeted and how you got into our systems, and the promise to never attack us again. Please send us your bitcoin wallet ID so we can proceed with payment.
13:27
Okay. We confirm all points. Our BTC wallet is [redacted]
14:06
Ok. This may take some time, but please confirm when you receive payment. I will write you when it is sent.
18:49
Okay.
19:04
Any updates?
16:58

18:51
Yes, we see the transaction, but it hasn't been confirmed yet. Please wait.
