I sent 0.0005btc from A btc address to my B btc address.

However, the blockchain.info wallet says the B wallet contains transactions which may be double spends.

And then, the 0.0005BTC was transfered to one new address which does not belong to me.

I tried to send another 0.02BTC from A to B, the same result.

The funds have not been sent back yet.

My funds have been taken?

lol pure bs in this

what is the meaning.... ???

Are you sending these transactions, or better yet, are you sending to addresses that you own?
It's probable that someone has gotten a hold of your private key and is just transferring your BTC to their wallet every time you make a transaction.
If this is the case, then yes, you've lost your coins.

I  imported the private key of B in mastercoin online wallet(https://www.omniwallet.org/) , is that web a trap?

 ???

normally to be considered a theft you have to have lost at least a few btc, also if using an online wallet you are asking for trouble ,

sounds like you could have just made a mistake, are you experienced sending btc,  why would you send btc to yourself vs. use your keys ??

May be a lesson for me ,but feel sad for btc and msc online wallet.

 :(

Why did you use that wallet and not blockchain are a well known wallet?
I personally can't see any reports on it stealing users funds, but yet again I've never heard of the wallet until now

The blockchain team would be the best people to support you in this...if what you say is true.

I get that you posted this here for help but I'm not sure what you expect anyone to do about it.

Can you provide also the TX id ? So we can help you , without the "data" it is a little bit complicated give you an help.

if would help that you provide us txid of the transactions that you have done

What are the transaction IDs? Did you check this at another block explorer, eg blockr.io? Blockchain.info often has bugs.

Do not send funds to addresses with compromised private keys.
I've took these btc.
I will not return them back. You've sent them to the address which is under my control.

PS. google for "1CAsRJ5Z9CXdhBwxrCVrf8kJNPBxYQJiH1" and read carefully about compromised private keys

PPS. Are you looking for counterparty assets? Wanna take funds from flawed accounts?

There has been a lot of reports lately, that blockchain.info has security issues. {Go check on reddit}

Nobody can say, if this is legit or just shill accounts spreading FUD in an attempt to discredit blockchain.

Keep the balance in ANY online wallet at the bear minimum and buy a hardware wallet like Trezor for daily use. I send all my coins for investment to cold storage, and some for daily use to Trezor and have not had any troubles sofar.  ;)

This is not problem of blockchain.info.
He sent his funds to https://blockchain.info/address/1CAsRJ5Z9CXdhBwxrCVrf8kJNPBxYQJiH1
The private key for this address is 5KRTiZDTBaEkVc********************AwbobA48yLFvTLS2C
A lot of bots know this address and sweep funds from it.

Why would he send BTC to that specific address? {Is this some phishing method, to trap noobies?}

Thank for the information, I will look deeper into this and warn people on other forums too.  ;)

Why you steal my money?

and your words seems with no shame ?

when and how you get the private key?

the bug of blockchain.info?

If this is ture , btc would become meanless....

When and how did YOU (LifeIsGreat88088) get the private key?
Somebody probably got it from the same place as you did, and then made it public.

This is not money. And they are not yours.

I wrote  program and it gave me this private key.

No. the bug of counterparty/libjs.

btc will come meanless in any case: true or false.

Discussion of it here which explains the issue in counterparty:
https://bitcointalk.org/index.php?topic=581411.msg6354731#msg6354731

The address is mine, I create it from the wallet!!

Damn it!!

This is dup-R signature flaw by counterparty.

What wallet?  It is old given the bug you encountered.

Fix the issue and amaclin may return it. He is usually helpful - many people will just sweep it and do not help people who have an issue.

You have nothing in your hands.
Any power you have, comes to you from far beyond.
Everything is fixed, and you can't change it.

I  do not care about the little money lost of this event. I really care about the whole thing of Bitcoin!

Did I create one address which the same with others?

The end of Bitcoin??

I am just one common user of btc, what wrong with you talking with those words.

and It is you took my money away!

where is your honest?

Do not import compromised private keys to your wallet
Do not give your private keys to anybody
Do not use untrusted services

How else can I help you?
I think this advises cost more than 0.02

PS. No. I do not return btc. I can give you knowledge and experience - they cost more.

I read the post :https://bitcointalk.org/index.php?topic=581411.msg6354731#msg6354731

and now ,I catch up the whole thing.

I have no more word to say, just keep the btc , It is ok.

 

maybe some one else has access to the private keys.
It could also be possible that the Address B belongs to an exchange/Gambling site. They usually keep shifting funds instantly.

Can you tell us which program you used to create this address?

Also, tell us where you downloaded it?

I created the address in blochchain.info very early in 2014, I am the original owner of the address.

unfortunately, my address is on the private key exposed list in the thread.

and I even knew nothing about this until yesterday.

However, it is lucky for me to catch up before getting more lost.

So, I wanna say thanks to all of you help me finding  the whole thing out.  :)

and I still a supporter and big fan of blockchain.info ,xcp ,msc , because I understand we are all early adopters of blockchain technology ,and maybe we should afford the risk of the innovations.

That is huge.... 400+ private keys being duplicated to more than one person.  :(

I hope counter measures are in place to prevent this in future. Is this in any way related to the increased reports on reddit of hacked blockchain.info wallets?

Hi Redditors,
 
Team Blockchain here. We take privacy and security seriously and it’s deeply concerning every time someone reports a breach. The top three issues right now are:
 
•Malicious Tor exit nodes
 •Weak password management
 •Sophisticated phishing attacks
 We have been working with some of the top bitcoin and network security researchers to identify malicious Tor exit nodes and warning users against the use of the Tor network in general. Sophisticated hackers are using Tor to compromise individual wallets and escape untraced. We’ve tweeted about this issue https://twitter.com/blockchain/status/522454637115617280 and recommended that users disable Tor access within their wallets.
 
For those interested you can read more about the Tor network issue here: http://www.coindesk.com/torban-monitor-bitcoin-over-tor-attacks/
 
If you want to disable Tor access as well as take some other steps to improve the security of your Blockchain wallets here’s how:
 
http://blog.blockchain.com/2014/10/22/5-tips-on-making-your-blockchain-wallet-more-secure/
 
The second issue we see is weak password management. It’s very tempting to use the same password online for different services but it also greatly increases your risk profile. We highly recommend using very strong, very unique passwords. Many community members rely on services like LastPass, Dashlane, or open source desktop solutions that never touch the web to create complicated passwords. Also, one of the strongest ways to improve security is to familiarize yourself with Two-Factor Authentication, which requires a unique and perishable code to gain access to your wallet.
 
You can set this up now here:
 
http://blog.blockchain.com/2014/04/...how-to-use-it-on-your-blockchain-info-wallet/
 
Over the past year, as Bitcoin has attracted a lot of attention it has also aroused the interests of digital thieves who create fake landing pages, send malicious emails, and even impersonate Blockchain employees to attempt to solicit login credentials. We have been spending tens of thousands of dollars quarterly, even when we were bootstrapped without outside funding, to take down phishing sites. We also work directly with Google, ISPs, and network providers to fight these issues daily.
 
There is always a tradeoff between convenience and security. We try to keep the barriers to wallet creation as low as possible so anyone in the world can create a Bitcoin wallet for free. We recently disabled automatic email backups because email access isn’t hardened enough for many users. To be clear, wallet backups have always been encrypted but if weak passwords were used there is a risk the backup could be brute forced by guessing common phrases.
 
We provide software that lets users manage and spend their own Bitcoins, without tracking, interference or permission. This also means that to a certain extent, our role is limited to educating users about best practices and innovating security features.
 
To this end, we are developing tools that will help users learn about security and audit their own security.
 
We've been blessed with a lot of great feedback that has helped us improve. If you have suggestions, we would welcome them here or at security@blockchain.info

What?

Take first 10 pages of directory.io
All these keys duplicated to more than one person.

Take English Oxford Dictionary and create brainwallets (classic & compressed)
All these keys duplicated to more than one person.

There are billions of private keys duplicated to more than one person.
Just do not use them. Voila.

If I read it correctly, OP's problem originated from a XCP bug back in April which leaked a list of private keys, and OP lost his fund because of reusing that compromised bitcoin address. So now there is one more reason we should never reuse our address apart from privacy issue .

How ? After creating an address with blockchain.info/bitcoin core/bitaddress, how do I know whether it is part of that billion or not ?

I lost 23800 safecoin linked to my btc address , who would take the responsibility?  XCP or blockchain.info?

BAD Samaritan:(

I improted the private key into the omniwallet of msc to claim my safecoins invested from the pre-sale.

After I got the balance of my safecoin , I found out that it need some btc balance to transfer the safecoins .

And then, the whole story begins after I deposited few btc into the btc address...

That one sounds like your own liability...

Unfortunate, but you should be the one to take accountability for your actions.
