Wallet Recovery Help

Hello!
I’m seeking help from the /bitcoin community to recover lost funds from a wallet.dat file. Someone I know asked me to help recover their lost funds - but I’m stumped and now seeking help from the experts.
Facts
Problems
Questions
I was under the impression that the wallet.dat file contained a private key which corresponds to any / all newly created receiving addresses, but I must be mistaken.
Any advice would be greatly appreciated. The person is at a dead end and I'm fresh out of ideas.
Thank you

IOTA funds were stolen (3.49Ti ~500k$) on 12th March 2020 after network relaunch [longread]

Hey CC comunity!
First of all, sorry for posting it a bit late I have some serious changes in my lifestyle and business due to Coronavirus situation in the world. For those who are infected I wish to get well soon and all the rest to stay safe and to stay home.
Here is my short story:On March 12th I made similar but short post regarding my stolen IOTA in the sub IOTA. First of all I met around 50% downvotes, I don’t know why but it seems that IOTA’s community don’t want to see posts regarding stolen IOTA, I got a lot of critics for using Trinity wallet instead of hardware and so on. But I see nothing strange using desktop wallet and it doesn’t matter whether it is IOTA Trinity or Bitcoin QT or Ethereum wallet unless in has strong manually typed password, VPN connection and some other security things. Or maybe IOTA’s community was afraid of unwanted bad attention during that market crash that day. So because of that experience I decided to make a post here at CC.
Some short reminder of what happened before my funds got stolen (https://status.iota.org)
Some news:https://www.coindesk.com/iota-foundation-suspends-network-probes-fund-theft-in-trinity-wallethttps://cointelegraph.com/news/iota-foundation-investigates-funds-allegedly-stolen-from-trinity-walletshttps://www.theblockcrypto.com/post/55955/iota-foundation-funds-stolen-users-of-trinity-wallet
If you don’t want to read that news here are some facts with timestamp:
February 12th 2020 - 18:55
As a precaution we ask you to keep your Trinity wallet closed for now.
February 12th 2020 - 19:20
After initial investigation we decided to turn off the Coordinator to make sure no further theft can occur until we find out the root cause of these thefts. (Lets say: “blockchain stopped”)
February 14th 2020 - 17:50
We have found the exploit.
February 15th 2020 - 00:50
After successfully identifying the attack on Trinity through a third-party integration
February 17th 2020 - 02:23
We have just released a safe version of Trinity Desktop to allow users to check their balance and transactions. This version (1.4.1) removes the vulnerability announced on 12th February 2020. (I’ve installed this particular version)
February 21st 2020 - 18:43
ACTION MAY BE REQUIRED TO PROTECT YOUR TOKENS IN TRINITY.
February 24th I left my country for some working trip
February 26th 2020 - 13:10
We are currently in the testing phase of the migration tools, once testing completes the tools will be audited by a external party. If this all goes well we are aiming to release these tools later this week.
February 29th 2020 - 19:15
The Seed Migration Tool is now available.
March 6th 2020 - 15:17
REMINDER: You have until 5PM (UTC), Saturday, 7th March to migrate your seed.
I’m still out of the country but I’m pretty sure I’m safe coz I’ve installed 1.4.1 wallet which removes the vulnerability.
March 8th 2020 - 18:15
The migration period has ended.
I got back to my country
March 10th 2020 - 16:45
We are aiming to resume value transactions around 5PM CET today.
March 10th 2020 - 18:15
The network coordinator has resumed operation. (Let’s say “blockchain restarted”)
Now my turn:

Same day I’ve made first post on reddit to get some attention to the happened situation. At the same time I’ve start to search for some technical support through over official telegram groups:
iotatangle
(https://imgur.com/McmrF3L)I’ve send a message where I’ve stated that my funds were stolen after network relaunch. Got some response from user Basti he invited me to another group with general discussion.screen shot 1 (https://imgur.com/hvDuoQA)screen shot 2 (https://imgur.com/MewdNm5)
Our short dialogue continued at the general discussion group iotacafe
(https://imgur.com/e9ErcPW) Where Basti introduced me to the IOTA Foundation member Antonio Nardella (https://imgur.com/WxZRk8N)
Before I started my conversation with Antonio I decide to get some information about him. I’ve found a Medium post with some welcoming words to Antonio Nardella.
(https://imgur.com/KK4zoOv) telegram(https://imgur.com/VquNCpi) medium
Seems legit.
Of course I couldn't be 100% sure it was him but the information he asked for wasn’t really sensitive so decided to share all I knew and all I did.
(https://imgur.com/X3Ha02Q) He also mentioned a wallet integrated service MoonPay, whether I used the wallet with this service or not and it didn’t matter if I used the service it self.
I’ve informed him that I used 1.4.1 wallet which was recommended to install on February 17th 2020(https://imgur.com/iZdNcm7)
When he gathered all the necessary information regarding loss of funds he took the time for sending this information for investigation team.
After a long awaited answer I got the same day this:
“Hello, I was informed that the loss of tokens is associated to the person/team responsible for the Trinity wallet attack via a third-party dependency from Moonpay.
As suggested on https://status.iota.org/, please file a report with the local police and to cite the following case number when doing so: LKA Berlin, Center for Cybercrime, case number: 200213-1717-i00290.”(https://imgur.com/Gov1v0i)
So, reinstalling the wallet didn't help me to avoid the loss of funds.
Well if my funds are proved to be stolen then it means - yes, I’ve used the Trinity wallet between the December 17th 2019 and the February 17th 2020. And yes, I wasn’t able to make seed transition during the given period. I was out of the country starting form Feb 24th till March 8th. I can even proove it with my border passing stamps… You know I didn’t use to take 4.5Ti with me just in case I would need an urgent seed transition. Could you imagine thousands of people with their multimillion Bitcoin holdings carrying private keys everyday with them just in case they would need seed transition… The funds were stolen not by my mistake but IOTA developers/foundation/etc (lets say IOTA team) mistake.
At the end of my story I want to take your attention to the fact that I didn’t compromise my PC neither wallet nor password nor seed. All my fault was for using the desktop wallet… How can you imagine your user without using your software/services/etc… I want to publicly call IOTA team (especially mr David Sonstebo) to cover not only those which were to happen back in the Feb 2020 but all the loses which were caused by that wallet vulnerability.

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.
