Thank you! I will send these to our management for review.
[Victim] — 01 Sep, 00:45 AM [NY time] — Message 17/44
They asked if you could provide proof of some of the files below:
[Victim] — 01 Sep, 00:45 AM [NY time] — Message 18/44
\\vhost2\data\v[redacted]\v[redacted]\virtual machines\   A few files from this folder. 192.168.0.31\data\sqldata\db[redacted]_eng.mdf 192.168.0.31\data\sqldata\[redacted].mdf
[Victim] — 01 Sep, 00:48 AM [NY time] — Message 19/44
Also, while we're reviewing the files, is it possible that the timer can be stopped as we're working on the funds? Thank you so much!
[BlackMatter] — 01 Sep, 03:31 AM [NY time] — Message 20/44
We cannot share files like you asking for because it is database files, and one of them is database of backup software. Timer updated.
[Victim] — 01 Sep, 23:26 PM [NY time] — Message 21/44
Thank you. Does that mean you don't obtain those .mdt requested above, and cannot provide them after payment, we would need to use the decryptor to decrypt them, correct?
[BlackMatter] — 02 Sep, 03:13 AM [NY time] — Message 22/44
You're right. Usually we directly download files instead of download whole VM.
[BlackMatter] — 05 Sep, 12:38 PM [NY time] — Message 23/44
Hello, any news?
[Victim] — 06 Sep, 02:30 AM [NY time] — Message 24/44
Hi. We checked the portal a couple of days ago and this chat portal was down, I couldn't get in to chat with you. I made a request via "Contact Us" button, (Request ID: [redacted] for your reference.) And we had a long holiday weekend. Can you extend the timer again due to the portal being down?
[Victim] — 06 Sep, 02:47 AM [NY time] — Message 25/44
Also, our management wants to make sure, once the payment is make: 1) you will provide us the data back through download, 2) you will delete our data from your side and provide proof, 3) you will provide us the decryptor, with support if there is any question or issue with the decryptor), 4) you will tell us how you hacked our network, 5) you will not publish the data or the blog post / any media that you hacked our network and data. We were just able to test the decryption too now that the portal is back up. Please confirm and I will let my management know. Thank you!
[BlackMatter] — 06 Sep, 03:13 AM [NY time] — Message 26/44
First of all we add 3more days in timer. 1. We will setup temporary onion website where you can download your files to understand which ones was downloaded. 2. We will provide shreder log-files with reports of deleted files so you will compare it with files ha you download. 3. Support for decryption available 24/7/365, but don't have any cases where it was needed. 4. Short penetration-test report with main killchain and recommendations how to prevent this in future. 5. Data in blog published only when we lost contact, so dont worry about it.
[Victim] — 06 Sep, 10:22 AM [NY time] — Message 27/44
Perfect. Thank you for the confirmation!
[Victim] — 06 Sep, 10:28 AM [NY time] — Message 28/44
Our management had a meeting today and they would like to ask if you will take $150,000. We know this amount is small compared to your initial demand, but please understand that we sell [redacted] to school and government, and as you know, since covid started, all school has closed or gone online so no one has been buying our [redacted], therefore we have been suffering as many other business. Also, looking at your main page, where you mention that you do not attack government sector, if we work with school and government like that, do we qualify for the free decryptor? Just thought we'd check. Again, thank you for working with this. Please let us know if any of these works for you.

Hello. You do not fall under our rules, it will not work for free. Maybe you mean 150k discount? We know your cash flow and amount what we're asking for is not overpriced.
[Victim] — 07 Sep, 14:00 PM [NY time] — Message 30/44
Thanks for verifying that we do not fall under your rules. Please understand that we are a small company and do not have significant capital, and we are here to negotiate in good faith. Our management would like to know the amount that you can come down off the initial demand. Thank you.
[BlackMatter] — 07 Sep, 14:10 PM [NY time] — Message 31/44
We can provide 20% discount and reduce 20% boost if you want to pay in bitcoin. So our best offer ~4-4.5M
[BlackMatter] — 07 Sep, 14:29 PM [NY time] — Message 32/44
You're not so small how you want

Hi. the bank statement isn't actually telling much, we have expenses that the bank statement doesn't show, and a lot of those money in the statement are not ours, they're on-hold funds from other entities. If we were to pay 4M based on that bank statement, we would be out of business. Our management came back with $250,000, which is the most that they can get at this point. Please understand and help us out.
[BlackMatter] — 07 Sep, 18:55 PM [NY time] — Message 35/44
Its too low, take a loan or smth because your offers is awful. We better lost amount that you offers than take this. We dont care.
[Victim] — 07 Sep, 18:57 PM [NY time] — Message 36/44
Can you please give us more discount? Really covid and everything have been hitting us hard. We really appreciate your help, anything we can get.
[BlackMatter] — 07 Sep, 18:58 PM [NY time] — Message 37/44

[Victim] — 07 Sep, 19:00 PM [NY time] — Message 38/44

[BlackMatter] — 07 Sep, 19:03 PM [NY time] — Message 39/44

[BlackMatter] — 07 Sep, 19:10 PM [NY time] — Message 40/44
Price and timer updated. Tell to you manager that he must think twice, lost encrypted data and publish whole company secrets versus 2.5M$.
[Victim] — 08 Sep, 14:37 PM [NY time] — Message 41/44
Hi. Our management has gone to the board and this is a huge number for them, they can try to squeeze out $350K now, please help work with us here and see if this is acceptable. Thanks for your help!
