Bitcoin Forum

So, yesterday morning I made a new address on my Blockchain.info wallet on my iPhone.
So a new address has been created, I send a payment of BTC0.58051 to my new created wallet.
As soon as I see on blockchain.info I get an unconfirmed transaction, my BTC addresses disappear on my iPhone.
I start to panic and I see to my transactions, these have disappeared from my iPhone too.

My wallet has gone from my iPhone by now, so I look up my PC and try to log in to my Blockchain.info account.
I put my account details in and I get an error. 'Error Decrypting Wallet. Please check your password is correct.'
So I guess my password to be wrong, however I didn't change my password lately.

I try and use all my known password combinations but none of them seem to work.
I tried recovering my wallet with the latest backup I had with the password I always used on Blockchain.info and I was able to recover my wallet.
Now I tried using my received backup I got in my e-mail from Blockchain after making the new address but my password is just not working.

It's only BTC0.58051 but that's equal to almost a rough 90€ which is a lot to me.

I already had contact with Mandrik from Blockchain.info and he closed the help request after saying there is nothing they can do about this.
I lost all my hope in Blockchain.info's wallets and I'm now using another online wallet.
I hope nobody else will have the same problems as I did receive now.

I can refer to these problems users 'recently' had with Blockchain.info too:

 - I lost 160 Bitcoins from my blockchain.info wallet! (http://www.reddit.com/r/Bitcoin/comments/1czrua/just_lost_160_btc_from_address_managed_with/)
 - Can't access my Blockchain.info's wallet anymore! (https://bitcointalk.org/index.php?topic=181925.0) <-- This is somehow the same problem I have
 - Complaints about blockchain.info's support (http://www.bitkoins.com/discussion/comment/52)

>My BTC will always be stuck in this address...

>stole

If they are stuck, they aren't stolen. The address is not controlled by blockchain.info, the service does NOT know your private key. Your password isn't working because someone intercepted your email and changed it, most likely.

We're extremely limited in what we can do for issues involving passwords not working. We can help track down lost identifiers, reset two factor authentication & IP locks, and even provide a history of backups for a user's wallet. Unfortunately if the password does not work then there is nothing more we can do. We have the lost password mnemonic page (https://blockchain.info/wallet/forgot-password?guid=). Whenever a password is changed by a user they need to make sure to note the new mnemonic. Otherwise the old password will still display when you enter the old mnemonic in. We certainly don't want people to lose access to their funds, so we try to offer as many backup plans as possible.

Yeah right, how could anybody hack my e-mail that has a 15+ characters password with combined UPPER & LOW case and special signs...
This isn't the case as I could log in right before making a new address...


I would've asked for a back-up right after and right before the new address was made.
But your support Mandrik closed the support thread.

But I just noticed he opened one again, thanks for that.

I know a lot of bitcoin, it's just a mystery why my password stopped working after I made the new address on my wallet

How did someone intercepted your email. Oops, don't tell me people still don't use https for all connection.  :o

As I said, there is no  chance someone intercepted any of my mails.
My password isn't in a mail nor it would be the same.

I had trouble with leaking wallets. Come back after 8 hours or so and it would go down .2 BTC for example. No longer do business with them and I'm much better off.

I highly doubt they stole your 0.58 btc like you say after they gave away 10 btc yesterday to 500k user.

Either you forgot/misstyped your pass (why don't you people use password manager like lastpass or keepass?) or you've been hacked (unlikely because coins would move).

But reading your post again it seems you actually created a new wallet and not just a new address. Check your emails for identifiers and make sure you have correct passwords for wallet(s) and you'll get your coins.

Indeed, I don't say they stole 0.58BTC, but when I press on New address on my iPhone I assume I created a new address, right?
And I have notifications enabled when I send or receive bitcoins, why would I receive this confirmation otherwise?

The ID in there is the same ID as always in the original mail, so...

Also what's rare is this:

As I try to import the backup where my password should be wrong it keeps saying 'Error Decrypting Wallet. Please check your password is correct.'

If you knew then you would know blockchain couldn't help you.

Just another quick update.
I just made a new address on my blockchain.info wallet using my iPhone again.
As I try to log in my password isn't working anymore, I guess the problem is inside the iPhone app.
Anybody else that wants to test this with me?

not connecting via HTTPS or falling victim to a man in the middle attack

I always use HTTPS

Could it be possible that the iPhone app has been compromised?
That if a user makes a new address it changes the user's pass immediately, send an e-mail to the 'hacker' and then he logs in to your account and then could steal all your Bitcoins stored in your other addresses?
Please take note of this Thinkpad.

Any wallet service provider that allows you to reset passwords over email has no idea what they're doing.


Did you make a new wallet?


This seems extremely unlikely. Are you jailbroken with OpenSSH installed, without changing the root password?

No, I press on new address in the My addresses tab using the backup Mandrik had restored on my account.
This created a new address, I now have added two, I can still view everything on iPhone, but I can't log in to my account on PC anymore.

No, my iPhone isn't jailbroken.
It's factory new and running on IOS7

Well... that's ...weird. I think every new address makes wallet to sync with server. It is possible something is broken. I just tried but on android and works as usual.

I know, that's what happened yesterday, but I don't know what the problem could be.


Did you made 3 using your iPhone?
Is you iPhone connected to your laptop using the cable?

I now get the message on addresses on my iPhone:


I'll post pictures of this later.

You now understand what happened and that I'm not a so called 'noob' or 'newbie'?

I don't know what the problem is either...
Try if you're connected to your laptop, I remember when it fucked up I had my iPhone connected to my laptop too.
How could I use two different wallet ID's? They are the same...

OP, how about you open your browser in your computer and access your blockchain.info wallet? starting to lose my faith too.

Well, yes, that's impossible, it says my password is wrong after I created a new address on my wallet using the iPhone app...
Frustrating as hell, I can't even get to my wallet using my iPhone app now...

Import the backup Mandrik gave you into https://blockchain.info/wallet/import-wallet and make sure you can login to the new wallet through your web browser. Note down the new wallet identifier on paper. Now the iphone app will need pairing with the new wallet. Tap the logout button in the top left -> Click Pair Device -> Scan the QR code as instructed from the wallet you just logged in to.

I've done that already yesterday with Mandrik.
But my address with the BTC0.58051 on it isn't in that back-up so it's pointless.
Also, as soon as I make a new address on my iPhone my desktop account isn't synchronised with my iPhone anymore and my password will be wrong.

Congratulations, you have discovered an obscure bug in the iphone app!

The issue is you have added a transaction note which contains a newline character. When the wallet is saved this is not properly escaped causing the json produced to be invalid. The iPhone app has not been updated since the notes feature was added so this was never tested.

Using the wallet details provided on zendesk I have restored the missing address (0.5 BTC) and deleted the offending note + added a 0.1 BTC bug bounty. So you should now be able to login again through the web interface and iphone app again.

The bug will be fixed next update.

OP, I suppose it's time to change the subject into "I RESTORED my faith in Blockchain.info"  :D

I always love a happy ending.

I can confirm that I have received the bounty and my missing bitcoins.
Thank you for your time in investigating this problem.

Does this means my name will get somewhere in the credits or in an article you'll write about this error?
If so, that would be amazingly awesome!


Indeed, I will change the topic name :p
And I guess this is indeed a happy ending.

I would like to thank the OP for taking the time to explore this issue on a public forum.

Likewise, the dev team for participating, eventually identifying and solving the problem, and providing enough detail to be both interesting and helpful.

Likewise all of the participants who weighed in with comments.

This type of interaction is highly appreciated by at least one person who is a customer and feels a need to monitor the evolution of the solution in order to decide how best to adjust and protect the assets I have at risk under it.

Reading through the thread and other related threads I got the moral of the story is do not use the iphone app yet?
