On blockchain.info it has some weird label: "00000123456":
https://blockchain.info/address/1Bn9ReEocMG1WEW1qYjuDrdFzEFFDCq43F

This seems to be a bug? Is this some brainwallet?

That label was added by the owner of that address. Anybody can label address they own in Blockchain.info - https://blockchain.info/tags

In that case the tag should tell us about the hacker, as it's most likely the hacker who gave it the label?

Yes but I don't think you should completely trust that labeling because I can label an address I created with your name. This can also be a trap for someone else. IDK.

P.S. 1Bn9ReEocMG1WEW1qYjuDrdFzEFFDCq43F & 1M9D9jbZz9yRDXPpGxQtjrF7KGUcTVPNy5 are linked with many other addresses. We might get something from any of those addresses. https://www.walletexplorer.com/wallet/08fc8ad4e41d607d/addresses

Both of the above would be imply that the addresses was in fact not created with a weak RNG with the intention of stealing funds of users who send funds to addresses created by the wallet.

Your description of the situation would imply that the wallet software that you downloaded creates addresses with a weak RNG, allowing the dev of the wallet to know which addresses users of the wallet will create in order to allow him to steal funds.

Does it has to do anything with Android RNG vulnerability but it is two year old thing? https://bitcoin.org/en/alert/2013-08-11-android

Originally I wanted to reply to another topic, somehow I created a new topic instead.

I'm not sure how this thing was done technically. Possibilities that I can think of:

I installed some malware with some other application.
Malware somehow installed without my action.
Man-in-the-middle replaced downloaded package with compromised one.
Original package is hacked

I'm not sure how to investigate this situation.

Why don't you post a link to the site that you downloaded the bc.i wallet from on the google play store? Once you do that, someone can potentially try to recreate your experience. I would personally doubt that the theft is due to any of the above, but rather that the theft (if in fact is legit) is due to using a version of a wallet that creates addresses that are easily predetermined to the dev who created the wallet software.

Interestingly it appears that every time that funds are spent from that address that the wallet is not emptied, sometimes leaving as much as .2 BTC unspent within the addresses spend linked together. Additionally, it appears that when funds are spent from addresses linked together, they are spent to various other wallets that are linked together.

Both of the above would be imply that the addresses was in fact not created with a weak RNG with the intention of stealing funds of users who send funds to addresses created by the wallet.

Your description of the situation would imply that the wallet software that you downloaded creates addresses with a weak RNG, allowing the dev of the wallet to know which addresses users of the wallet will create in order to allow him to steal funds.

I do not have access to a VM that would allow me to safely download and open the file you linked, so I am not able/willing to take a look at your file, and I would recommend that anyone trying to help not open the file without the safety of a VM

I may write code in exchange for bitcoins.

If I understand you, you're saying that when you downloaded and installed a wallet program you tried to create a new address but you got this one instead:

https://blockchain.info/address/1Bn9ReEocMG1WEW1qYjuDrdFzEFFDCq43F

As you saying that the particular app on the google play is actually a malware which gives people compromised addresses? If so, you should probably try to report it on the play store. If this is the case, you can't be the only one who has experienced this. Are you sure you got the app signed by blockchain.info and not some look-a-like one?

This happened to me tonight, although not with as big amount.

The wallet I installed was Blockchain.info Wallet from Google Play. The reason I chose to install this software was, because it allows to spend unconfirmed balances and I didn't want to wait between buying coins in the ATM and spending them for a beer. I chose to create a new wallet, scanned the code and charge it with some bits: https://blockchain.info/tx/358229fc237ce2653dbad4dd18b10f244c705f0a649c473a4bcb708daf373eac (1Bn9ReEocMG1WEW1qYjuDrdFzEFFDCq43F)

I wanted to spend some of it right afer that, but it didn't submit... One or two minutes later, these funds were transfered somewhere else:
https://blockchain.info/tx/d700a81eaa5fb61800bba77639a84a6c29c42b7158521f7a886ed0207848dc5c
https://blockchain.info/tx/2b49fd78440ad80ddacd3587f968411fb110213137b33e42f46141e9616ab92f (1M9D9jbZz9yRDXPpGxQtjrF7KGUcTVPNy5)

My phone is obviously compromised and 0.167 of my moeny is lost. Backup created this file, but it is password protected and I don't think it is of any use anyway: https://www.dropbox.com/s/eb9h6olulm40c9w/wallet-2015-05-19.aes.json?dl=0

Be careful, when you create a new wallet. Make sure it doesn't have a history.
