I've withdrawn 1000 USD (Euro Bank Transfers) from my Mt Gox account 20 days ago and my money still hasn't arrived. I wrote them but I got only the following message:

Mt Gox security seems to be nil but the owner speaks only about user passwords as if suddenly in the last few days a huge number of Mt Gox users turned to schmucks and allowed their passwords be lost.

What is the common factor in all the thefts? Mt Gox, but I see nothing from the owner about his security. I see a number of posts by users who lost BTC but have gotten no response from the Mt Gox owner. Who says user password security is the problem? Mt Gox. There seems to be no accountability and the users are presumed to be at fault even though they are crime victims.

They can fix database vulns for one, and they could make password cracking a little harder.... Even dictionary attacks are easy on this site. If Someone had the balls to do it, they could steal almost a million dollars from this site easy.

If you fail at entering your password more than 10 times, your IP is blocked. Even using proxies you'd probably run out of proxies before running a basic dictionary.

I believe this makes this kind of attacks non practical.

(as for hashing, we use standard unix md5+salt, will switch to $2a$ or $5$ eventually)

You forgot multithreaded attacks, dyn DNS, round robin shell cracking, and a whole lot of other ways to crack passwords.

With all respect, if somebody uses your password to steal your money, it's not about service security but about user stupidity.

I'm absolutely not saying that it is not a crime or that people like that should not be tracked and so on. I just don't think it's anyhow related to how secure exchange is.

I'd like to know how someone could get my password. My system is clean! No viruses, Malware or anything. I even ran a packet sniffer to see, there was nothing odd at all. I agree with you, a weak password is almost an invitation in the same way a mini skirt is an invitation to rape! I have found a way around this. I no longer have any funds in MTGox.

there's no way they woudn't be hashing, its a entusiast built site, not a corporation one...

well, lets think about for what mtgox.com does get a small fee (0.65%)?
for a nice blue sky? or may be something else? Grin

Not secure! My friend lost over $1000 after someone hacked his account using multithreaded brute force. Blame lulzsec. Use tradehill instead, it is much more secure. MtGox has multiple SQLi vulnerabilities...

Hi, Please direct issues regarding security (such as those) to [email protected]
We will enforce more secure passwords on Mt.Gox (refuse simple ones) and add the ability to set a withdraw password.

Well, Mark...

Just tell us first what kind of "marked bitcoins" you mentioned (this is the part of your answer to my postbox at [email protected] about my stolen 13.4 btc during DDoS at 06/14/11 16:20):

We have however marked your 13.4 bitcoins and will be tracking those over the network. If someone deposits those funds on Mt.Gox, we will know immediatly.
Thanks,
Mark

Satoshi will be suprised Grin

Do you cherish your reputation? It seems to be not...I`ll tell my friends, they`ll tell other...Lets see how long mtgox.com will go on...

I`m going to make a new more interesting topic about this nice exchange...

yes this isnt the first time ive read about it here.

everyone should be using a secure password,

for the really paranoid, or if you're dealing in large figures consider:

as mentioned shifting btc in and out as need be is a way to protect them and its 'free' and 'fast'

as for usd i would consider withdrawing them in and out as need via liberty reserve (its fast but there are fees 2% to withdraw) or dwolla, a bit slower but only 25c to withdraw

ultimately this is an issue that could make or brake an exchange, and core to its survival.

as i mentioned in another thread, it seems ironic that many of us would have more money in mtgox than in our bank accounts yet with less security login checks.

no its not.
It says that my IP has been blocked due to multiple login attemps from the same IP address, when I tried to login for the first time for the day.
Tried this on multiple locations, got the same result.
