I wonder if this was some ICO issuing unannounced refunds? It came in over a week ago but I just now noticed it:
0x78482281699b48dd34a2d521D1fE1E6e22e25314
Can you list the amount of ICO that you have invested at pretty much ever? It's funny because some people went compulsively investing on every single ICO in town during the ICO hype thing and a some of them never got anywhere, this made people get their ETH back a ton of time later and they didn't even knew that invested on there. Some people isn't able to track back what exactly they invested at and what amount because they went into a ton of ICOs.
Well, they know who you are now!!! You can google the address and it comes up a bunch of time, I came across this (slightly unrelated) nearly made me cry
https://github.com/bokkypoobah/EthereumFoos#dont-leave-your-ports-openone of the results was listed in bokkypoobah's github - perhaps you could ping him and he might help - some attack.
Do be careful though - sounds like the opening scene of a B movie.
OP has turned into a millionaire in a matter of seconds. I would personally contact them, and they might give you some type of reward for returning their ETH, or go dark.
As the guy above said, which couldn't be expressed any better, it's opening scene of a B movie.
LOL, I wish.
Actually I've only invested a small bit in 3 tokens yet to be released and MAAS
was one of them. So it seems my gut feeling was probably right and they refunded the pre-ico buyers.
Also, I have a hw and sw firewall just in case but most of my coins are offline anyway
EDIT: oooor apparently they did announce it but the two most recent thread pages didn't make that explicitly clear when I browsed them earlier, guess that one's off the blocks
