Omg, someone cleared 3 of my accounts....
I used 256bit keys generated by Keepass 2. I am using NRS 0.5.8 that installed today and downloaded from nxtcrypto.org. I am using Windows 7 Professional and am running Avira and Microsoft Security Essentials.
The NXT was transferred about half an hour ago, also while i was forging.
My PC was running unlocked but i can be 99.99% sure that no one had access to it physically. So I don't really know how this happend?!? It can't be bruteforce right?
My accounts:
8423671173148912884 107,217
12345678612257264594 71
13486646175575465553 998
The NXT are now in this account:
696356957947686421 Balance Total : 108,286 NXT
Fuck me...
Btw the password of the third account was for example: af5c73ca7cf5f25ffa3b6b1689f40aaf60fd040b0de298c1ca661f8602d38311
Any chance of seeing these NXT again?

This is not a fully secure password. This looks very much like a Hex number. Only lower case a to f and Numbers. Something like that, even as long as it is, is cracked rather fast.
It seems someone out there is brute forcing with number chains.
I had an account which had another rather serious flaw in choice of password. It was luckily not hacked.
