I'm not sure who's running things there (if anyone) but he had said he turned over duties to some friends. Milw0rm was (is?) a source of quality PoC exploit code, much of which was zero-day. For security research, it used to be a great resource. I, too, have noticed it hadn't been very active lately, so it's hard telling who (again, if anyone) is running things there.
Also, I haven't really seen any other posts about str0ke's death, other than ones linking to bl4cksecurity or mentions of it quite a while after the initial post there.
It's not that I would consider it a hoax, but it highlights one of the oddities of pseudonymous culture. First and foremost, I was under the impression he was in his late 20s from his profiles elsewhere on the web, and the link says he was born in '74. Again, pseudonymous culture means that data could be false, accounts could be impostors, etc.
I don't usually reply to my own comments, but just to point out a few examples of the F'd up things people do, including "making others dead over the Internet":
str0ke @ milw0rm has passed away due to cardiac arrest early this morning at 9:23 AM. We @ blacksecurity are deeply saddened by the loss of a good hearted friend.
At the risk (certainty?) of being downvoted, that's an interesting choice of words.
For those who don't know (I didn't), it appears milw0rm is a kind of exploits database:
It was kind of the startup of the security world, and it became popular very fast. It required a working proof-of-concept (POC) for publishing - no pie in the sky text only stuff.
milw0rm is (or was) one of the first places I check each morning for new info. I was worried about the lack of updates - and this is sad news for both the security community and, obviously, str0ke's friends and family.
Having children is sufficient, but not necessary for part of one's essence to continue to live. There are many great "DNA-less" ways to do this. For those without biological children, you can live on through hard work and good deeds that benefit others.
