This happened to me a couple years ago. I knew it was spam but I found it very offensive and rude, so I reported it to Internet Crime Complaint Center (IC3). There is a simple online form you can fill out to file a complaint. It will make you feel like a responsible citizen - see something, say something - for a minute or two.
Anyway, today, I got the exact same letter as you, not once but twice. I couldn't believe it. I thought I would Google Cobalt Strike "Beacon" to see if it was even a "thing" and that's when I saw your post. The only difference between your letter and the two letters I received is the Bitcoin Wallet ID No.
So if you want to report it I've provided a link to the IC3 where you can fill out the form, as well a link to the Federal Trade Commission where you can report it and read their tips.

And for the record, there were no frantic calls from family and friends expressing their disbelief after watching one of my videos. So, check back with me after Saturday. That's when my 5 day deadline is up.
I received this spam today...my first time! It's the same template as others have shown here, with minor differences. It did scare me for about five minutes, since it did sound plausible. Two minutes of Google led me here, so I'm relieved it's fake. And I will get serious about my password management. I wish they offered to sell me a password manager...that would have been funny.
