the .msg file is a exact Verbatim copy of the email I received from the BitCoinTalk software alerting me about the changed password.
Many antiviruses block .msg due to it can carry viruses, but this file is as safe to open as any email from BitCoinTalk.org
Ok, i just download and scan it and its clean.
But still, did you think if thats ip is the real hacker's ip address?
And AFAIK hacker always use different ip address or hide their real ip address. So, i don't think that's the real hacker's ip.
