I'd like to claim my BTX (https://bitcore.cc/).  It appears that I need to import my private keys from my Trezor (https://steemit.com/crypto-news/@xwerk/bitcore-btx-guide-the-2nd-snapshot-for-btc-hodlers-free-btx-or-how-it-works).

Can someone explain how this can be done safely?

Thanks!

Not sure if I understand what you're asking for, the BTC address where the coins were stolen from?  That's already included in the OP.

Yes, that was my wallet address.  So if the hacker gained access to my wallet, could that have been his location based on that IP address?

My location?  No, I was nowhere close to Bellingham Washington.

And to everyone else, I appreciate the feedback.  Agreed that it's close to impossible, but want to make sure that's the case because it's obviously a lot of money.

I likely agree.  However, I could get the authorities involved and maybe something could be done then assuming he has the means to purchase the equivalent (or some amount) of BTC to make me whole.

Hi all,

So I know it's a LONG shot, but back in August of 2013, I had 40 BTC stolen.  Basically somebody hacked into my Gmail, found my wallet.dat file, and then moved my coins from my blockchain wallet (https://blockchain.info/tx/3ea2a7343d5623058ac7cc403d82e4fc9a351ef0e8818f1fe0d1b3351e6ad434).  I was quite dumb back then, and didn't have 2FA enabled on my Gmail.

I am not tech savvy enough to try to identify the perpetrator (though I know even if I was it's very difficult due to possible IP masking and use of a mixer), but is there any way I can post a bounty here for 5 BTC if somebody is able to track down my coins so I can retrieve them?  Or is there somewhere else I can post a similar bounty? 

I know it's a very long-shot, but I feel like $25K USD may make it worthwhile to try for somebody.  I can obviously provide more detail (and some of that can be found here - https://bitcointalk.org/index.php?topic=269443.msg2882400#msg2882400)

Thanks!

Edit / note: The bounty would be contingent on me retrieving some or all of the funds since I know it is a long shot and I'd need to get law enforcement involved. Apologizes if that was not clear in my original post.

Sorry, but just to bump this one more time, where would be the best place to find people willing to help out for a finders fee/bounty?  Here, another forum, etc.?

Thanks for all the advice everyone!  I really appreciate it.  And as a quick recap of what I believed happened, somebody hacked into my Gmail (as there was records of access by someone outside of me) and then used the backup that Blockchain had emailed me to steal the coins.

I know it is a long shot, but I'd be happy to offer up a 10 BTC reward for anyone who could help me find them, but only if I was able to actually receive the stolen coins back to my wallet.

If anyone else has additional advice/thoughts feel free to post here or DM me.

Are there any companies or individuals that help track down stolen bitcoins?  I had 40 BTC that I had on Blockchain stolen awhile back (https://bitcointalk.org/index.php?topic=269443.0), and was wondering if there are any people that will help out for a fee?

Donated.

Only if they were lost and not stolen.  If they were stolen, they've likely been being sold over the past months or years and are still in circulation.

No, I only had 2FA on Blockchain.

Got it.  Thanks for explaining this in a very clear manner.  This is very helpful for me as most of this stuff is way over my head.

I guess I'll contact Verizon just in case, but as you mentioned, the thief probably wasn't stupid enough to use an IP that could be traced back to him.

Given a recent theft of over 40 of my bitcoins, I've decided to take security much more seriously for Bitcoin and all other areas of my life.  As somebody who uses a computer pretty much every waking hour, I'm still a newbie when it comes to this sort of thing. 

Can somebody please explain to me, or point me to good resources, to develop (and remember) secure passwords in addition to any other security measures I should take?  I've done some searching through the forums, but I didn't find anything that really helped me with this.

Is something like https://lastpass.com/ a good idea?  Or do you have better suggestions on how I should manage my security for now on.

I posted this issues in a separate thread at https://bitcointalk.org/index.php?topic=269443.0, but somebody suggested I also post this here since it is a Blockchain related issue.

Yesterday when I logged onto Blockchain.info, I noticed the 40+ BTC I had in my wallet were gone and had been sent to this address 1GvmpUY1RdR5zf7jDZnpjfuBnoCz3S2xSS at 12:20am Aug 2nd.  I'd appreciate some help to understand what happened, and if possible, how I can get the BTC back.  I'm not a tech person, so it's been a struggle to learn what I have about Bitcoin...

Here is the transaction information.  https://blockchain.info/tx/3ea2a7343d5623058ac7cc403d82e4fc9a351ef0e8818f1fe0d1b3351e6ad434  Please let me know if there is more information I can provide that would help.

I had previously used a paper wallet, but transferred my money back to Blockchain to enable easier transactions.  When I imported my paper wallet back to Blockchain, it was to my original wallet address that I'd used from the beginning.  I was using 2 factor authentication with an SMS code being sent to my phone to be able to access my wallet.  I did not notice this at the time, but now that I checked, a wallet authentication code was was sent to my phone at 12:17am Aug 2nd.  I do not recall ever seeing this until now.

After doing further investigation and digging through old emails, I've learned the following:

When I first signed up to Blockchain, I stupidly emailed myself my Blockchain username, password, mnemonic/security phrase, and wallet address.  Later on Blockchain emailed me an encrypted wallet backup.

After reviewing the IP addresses that have accessed my Gmail (https://security.google.com/settings/security/activity), I noticed one that appeared to access from an iPhone that I did not recognize. It was also a Verizon network iPhone and the IP address was mapped to about 30 minutes outside my city. This was on July 18th (and the theft happened on August 2nd).  Potentially also of note, I used public wifi at a hospital on July 30th.

Is this the likely scenario? That my Gmail and/or iPhone was compromised?  And would this explain why I recieved an SMS text from Blockchain 3 minutes before the theft?  If so, is it possible to locate the person who accessed my Gmail from that IP address?

Thanks in advance for your help.

Thanks for the clarification.  However, would this sort of attack still trigger Blockchain to send me the SMS code like they did 3 minutes before funds were transfered.


I used bitaddress.org and just created and printed one from there.  I know there are a number of other security measures one can take to make this process much more secure, but since I'm essentially computer illiterate (despite Excel and PowerPoint which I use for work...), I did not go through those procedures because I could not understand them.

Given that I've possibly identified the IP address of the attacker as mentioned previously (After reviewing the IP addresses that have accessed my Gmail, I noticed one that appeared to access from an iPhone that I did not recognize. It was also a Verizon network iPhone and the IP address was mapped to about 30 minutes outside my city. This was on July 18th (and the theft happened on August 2nd).  Potentially also of note, I used public wifi at a hospital on July 30th), could I call Verizon to confirm that that IP address was not associated with my account?  If it was not, could I then file a police report on the matter to attempt to identify the individual using that IP address?

I know that is a longshot, and I've come to terms with the fact that I will likely never see that money again, but if there is a chance through that course of action, I'd take it.

Most importantly, I want to learn from this experience for when I purchase more BTC in the future, and provide a case study of what not to do for others so the same thing doesn't happen to them.

At one point I moved everything from Blockchain to a paper wallet.  At a later date, I moved everything from my paper wallet back into my Blockchain wallet by using the "Import Using Paper Wallet" option.  Is this what you are referring to?

Just so I can understand, if the thief did not actually have access to my phone (physically or remotely) to get the 2 factor code, would he still have been able to send the money from my wallet?

On Blockchain, it says the following: "Lost Two-factor Authentication Details.  If you have lost your two factor authentication details your wallet is still fully recoverable. All we need is reasonable proof you are the account owner which can be provided by completing the form linked below."

It then asks for information that could have been gleaned from emails in my Gmail such as wallet identifier, secret passhprase, email address, etc.

If that 2 factor code would still be necessary under those circumstances, I would venture to guess that somebody gained access to my phone through a virus of some kind as you suggested.  I don't have any tech savy friends who were with me at the time that would have the first clue about doing something like this (and my phone was with me in my room that I'd barely left all day because of a surgery recovery.

To answer another question above. When I imported my paper wallet back to Blockchain, it was to my original wallet address that I'd used from the beginning.
