Stashes of stolen funds are being moved to various addresses, tracking them will become harder.


someone will cash out the funds and he will be VERY rich Smiley)

what is somehow funny is that other exchanger will fulfill the transaction.

Stolen funds are processed without any problem. This is money laundering which is possible through Bitcoin.

When a criminal activity(hacking in this case) generates substantial profits, the individual or group involved must find a way to control the funds without attracting attention to the underlying activity or the persons involved. Criminals do this by disguising the sources, changing the form, or moving the funds to a place where they are less likely to attract attention.

it cannot happen a such thing with a real bank account even the funds are stolen somehow, you can surely recover them in a very short time.

They will need to use very smart techniques to cash out the funds but nothing too hard. If they are Bitstamp employees, they will be observed.

really?  how? Smiley

they will exchange the funds to Altcoin or any other e-currency and done. they can start a new life on a tropical insland and 2-3 cheeky girls Smiley)

They need to mix the bitcoins before they send it to an alt exchange and changing 19 000 BTC in altcoins won't be done overnight, will it? I agree they will succeed to cash out or hide all 19 000 BTC.

WTF is this.... I've been out for a couple days, came back to make some trades, and see their website is completely suspended. I'm getting the mtgox deja vu. I've got a hefty sum of both BTC and fiat on there  Angry

As if price haven't dipped low enough, this incident will most likely further dip the price, and I can't even move whatever BTC for fiat stuck on there...

Wow man that sucks. Why would you keep a heft sum of btc and fiat on the exchange?


I don't purposely store on there, but rather people that actively trade don't really have a choice. Wiring fiat takes a day or more, and depositing BTC requires 6 confirmations. I can't sit around for an hour just waiting when I need instant trades.

what happened with bitstamp?
MtGox II Huh?
wish it is not.
but if bitstamp were gone, are there any single bitcoin exchanges? the future will be the world of altcoin exchange and leverage casino.
Lakebtc.com is also a exchange which only support bitcoin and no leverage

For bitstamp, we don't need to worry about, since bitstamp issued a notice, this thing is definitely that mend the fold after few sheep have been stolen
okay, lakebtc is an alternative

but 12 hours later, bitstamp still suspend, I worried about how long it would last?

just like hgmichna said:
… BitStamp can cover the loss. they made millions as profit from their clients so they can cover almost any loss …

Funny, people said exactly that about Mt. Gox, less than a year ago.

How long shall we need to wait for it? were it back, right?
coindesk sat bitstamp loss 18,000BTC
bitstamp say theymself loss less than 19,000BTC

thus, bitstamp's loss at least 18,000BTC, if $280 per BTC, nearly $5,000,000 of shortfall, bitstamp say they can afford to loss...

ok, you ask me how long? please review the case of mtgox which began in August 2013 and end in February 2014

hope LakeBTC don't have such problems recently

Proof of solvency Smiley

They know it, why they simply don't post it?

"Better don't show proof of solvency and let people wonder whether you are solvent or not than show it and make everyone be sure you are not"

Plato

It is better not to show if you are not solvent or do some shady and not precise accounting. The only good explanation of not showing would be not to give away how their security is organized because if you show everything is in a single cold storage wallet, you have gave away an information.

New message from Bitstamp now up on their web site, but it does not significantly differ from the first one. They now admit to the loss of "less than 19,000 BTC".
they claim they can cover the losses in full...

Yet they post no proof they have that much in reserves to do so.

Just more words. Reminds me of gox.
They haven't proved they control a single satoshi yet.

We know they used to have enough BTC to allow all withdrawals that were taken place. Which means they had at least a small portion of the BTC they are supposed to have.

I am looking for this information. We don't know the cold wallet addresses so 19,000 BTC may have been a huge portion of the bitcoins they hold if they had fractional bitcoins reserves and less valye than what is deposited in the bitstamp accounts.

Isn't that just the cold wallet address that they moved all their deposits to.

I don't think anybody stole 18,000 coins from Bitstamp.

It is speculated that is the address that bitstamp's hot wallet (or a portion of their hot wallet)'s coins were sent to. Blockchain.info has labeled the address as such as well.

In theory bitstamp could have noticed some kind of problem and quickly started to transfer all the coins into that address. Whoever was sending funds was sometimes including ridiculously high transaction fees which would be unlike what you would expect them to do, however the high fees could potentially be a result of a panicked technician who was trying to create as many transactions as quickly as possible to get the coins out of their hot wallet

edit: per the bitstamp website 19k bitcoin was in fact stolen from their hot wallet

if im right bitfinex also stores btc at bitstamp, so if you don't want to be finexed withdraw now when it is still possible  Cool
Never ever let bitcoins on an exchange, honestly I just hope they close down and take bitfinex with them, exchanges need to keep going down untill people realize exchanges are for exchanging bitcoins and not for storing, cold wallets are meant for that
I warned you all ...

good point, start withdrawing now when it's still possible. you cannot be sure what's tomorrow Smiley

Where can I find that information that bitfinex keeps BTC on deposit at bitstamp?

Coinbase is using Bitstamp too.

But here are the information requested:

ask the money back from Bitstamp.
Almost all their BTC should be backed by real money (USD or EURO). these money are into their bank account.

they "lose" the BTC but the real money will remain to them if you will accept the "loss".
Most of their money are coming from bank deposits not  direct BTC transfers.

So, ask your money back by bank wire asap. Their bank will froze the account shortly.

Looks like they've already confirmed the safety of the large bulk of funds and will compensate whats been lost on the hot wallet.

https://imgur.com/vrNSUzG

That only could be confirmed with proof of reserves, not just some words.


People should start using services where service providers do not take over control over the coins at all. This is possible with user-side encrypted private keys, multi-signature wallets and even backup transactino in case the service goes completely offline.

bitalo.com or greenaddres have implemented these systems, people just need to use it

The Rock Trading implemented multi-sig with greenaddress

Clearly, multi-sig should become the standard, otherwise know you are in risk.

I received the same email.

Before that I ordered a bitcoin withdrawal, which has not gone through until now, since 15 hours. 20 min after the withdrawal, when I did not see any transaction, I entered a support ticket. There has been no reply to that. Note that the two issues look unrelated at first sight, but only if we believe what they are saying.

It feels like Mt. Gox. Delay and finally stop withdrawals. Blame technical problems or hackers. Worst case is that they gambled on a rising bitcoin price and lost their shirts when the price kept going down.

Not again! I have lost enough on Mt. Gox. If large bitcoin exchanges keep going down, bitcoin could die altogether. Bitcoin is useless if you cannot exchange it reliably for fiat money and if you keep losing it through failing exchanges.

I remember only too vividly how I kept hoping to eventually withdraw my Mt. Gox money. It never happened.

It may be the right time to sell bitcoins, just in case Bitstamp goes down and before the issue becomes widely known. If the fears turn out to be unfounded, buy them again.

BitStamp can cover the loss. they made millions as profit from their clients so they can cover almost any loss IF they want that, of course. The Bitcoin price will go down for sure. It's a normal. This is happening on any stock market when a BIG company has problems; the whole market is going down for a period of time.
If the Bitcoin price will not fall, that means something is fishy...it won't be according with the any common sense... Smiley

BITSTAMP SERVICE TEMPORARILY SUSPENDED

We have reason to believe that one of Bitstamp’s operational wallets was compromised on January 4th, 2015.
As a security precaution against compromises Bitstamp only maintains a small fraction of customer bitcoins in online systems. Bitstamp maintains more than enough offline reserves to cover the compromised bitcoins.
IN THE MEANTIME, PLEASE DO NOT MAKE DEPOSITS TO PREVIOUSLY ISSUED BITCOIN DEPOSIT ADDRESSES. THEY CANNOT BE HONORED!
Customer deposits made prior to January 5th, 2015 9:00 UTC are fully covered by Bitstamp’s reserves. Deposits made to newly issued addresses provided after January 5th, 2015 9:00 UTC can be honored.
Bitstamp takes our security and soundness very seriously. In an excess of caution, we are suspending service as we continue to investigate. We will return to service and amend our security measures as appropriate.

It will be bad if case like MtGox Happened, bitcoin price will falling down again Sad
Maybe it's time to sell ?


I would sell if I were you...even it is a "small" issue with Bitstamp(i think they are hacked and they lost a lot of money but they earned a lot from their clients until now, so they can cover).... the Bitcoin price will go down; may around of 200 or lower USD.

I made a withdrawal just over 24 hours before receiving the email.  That withdrawal had been sitting on pending since then.  

It's defintely related:
Quote
Today our transaction processing server detected problems with our hot wallet and stopped processing withdrawals.
That's from their email.

I had been making somewhat regular withdrawals during this period:
- The last successful was seen by blockchain.info at about 2015-01-04 02h20 GMT
- My withdrawal at at bitstamp at somewhere after 2015-01-04 04h00 GMT was not processed.

I suspect their system stopped withdrawals somewhere in between those times.

I hate to say it but that indicates a small(?) lie.  I.e. their email said "Today" but was dated 5 Jan.  I at least received it more than 24 hours after my withdrawals were being blocked.

deposits should never go to a hot wallet.

That doesn't really matter if your customers are using unique addresses for each deposit. If an attacker can access your hot wallet, chances are he can give your customers deposit addresses that he controls.

1: They need to prove right now how much money they have in cold storage
2: Bitstamp needs to be actually audited (by financial professionals) on a regular basis in the future
3: IMPLEMENT MULTI-SIGNATURE FOR WITHDRAWALS

If 3 doesn't happen, this will keep happening forever. We have the tools, but we haven't forced our complacent, amateurish, borderline criminal exchanges to adopt them.

It's time to pressurize them.

deposits should never go to a hot wallet. This point does not make much sense to me. It seems to be a severe incident and I assume it does not even matter if you have FIAT or coins there.

People should start using services where service providers do not take over control over the coins at all. This is possible with user-side encrypted private keys, multi-signature wallets and even backup transactino in case the service goes completely offline.

bitalo.com or greenaddres have implemented these systems, people just need to use it

A hot wallet is only supposed to have a small amount of BTC, enough that they can easily cover losses. If it's only the hot wallet and they were using the hot wallet correctly (IE only having a small amount of funds in it) then everything should be OK.

I received the same email.

Before that I ordered a bitcoin withdrawal, which has not gone through until now, since 15 hours. 20 min after the withdrawal, when I did not see any transaction, I entered a support ticket. There has been no reply to that. Note that the two issues look unrelated at first sight, but only if we believe what they are saying.

It feels like Mt. Gox. Delay and finally stop withdrawals. Blame technical problems or hackers. Worst case is that they gambled on a rising bitcoin price and lost their shirts when the price kept going down.

Not again! I have lost enough on Mt. Gox. If large bitcoin exchanges keep going down, bitcoin could die altogether. Bitcoin is useless if you cannot exchange it reliably for fiat money and if you keep losing it through failing exchanges.

I remember only too vividly how I kept hoping to eventually withdraw my Mt. Gox money. It never happened.

It may be the right time to sell bitcoins, just in case Bitstamp goes down and before the issue becomes widely known. If the fears turn out to be unfounded, buy them again.

I have the same issue. I'm wondering why there's not more people posting in the forum about this.

I just received an email with that:
Code:
Dear customer,

Today our transaction processing server detected problems with our hot wallet and stopped processing withdrawals.

You should STOP SENDING bitcoin deposits to your Bitstamp account IMMEDIATELY as private keys of your deposit address may be lost.

Your bitcoins already deposited with us are stored in a cold wallet and can not be affected.

We will send you more info as soon as possible.

Best regards,

Bitstamp team
EDIT:
Bitstamp is down now: http://www.bitstamp.net/

Code:
BITSTAMP SERVICE TEMPORARILY SUSPENDED

We have reason to believe that one of Bitstamp’s operational wallets was compromised on January 4th, 2015.
As a security precaution against compromises Bitstamp only maintains a small fraction of customer bitcoins in online systems. Bitstamp maintains more than enough offline reserves to cover the compromised bitcoins.
IN THE MEANTIME, PLEASE DO NOT MAKE DEPOSITS TO PREVIOUSLY ISSUED BITCOIN DEPOSIT ADDRESSES. THEY CANNOT BE HONORED!
Customer deposits made prior to January 5th, 2015 9:00 UTC are fully covered by Bitstamp’s reserves. Deposits made to newly issued addresses provided after January 5th, 2015 9:00 UTC can be honored.
Bitstamp takes our security and soundness very seriously. In an excess of caution, we are suspending service as we continue to investigate. We will return to service and amend our security measures as appropriate.
Bitstamp Team
On bitstamp.net I can't Deposit or Withdraw BITCOINS.
They will close the activity like mtGox?
