Re: 24 BTC stolen from my bitstamp account 2FA and email confirmation protected
by
leshow
on 05/03/2014, 07:00:41 UTC
Most likely a login session on the phone was not terminated, so hacker simply re-enter bitstamp and at the same time email account is usually auto-login, no 2FA is required

There is a weakness from bitstamp's side: You don't need 2FA code for withdraw. Since usually your email session is always logged in, once a malware took control of the device, he only need to wait until you logged into bitstamp

I just checked my computer, my email session is always automatically logged in, so it is also possible a malware can withdraw all my coins when I logged into bitstamp. Scary but true Embarrassed Embarrassed



this seems like the most likely to me. it bypasses 2fa and if they already had your email it would be easy. wait till you log in to bitstamp, initiate withdrawal, confirm the email.

if it is from inside bitstamp it's very scary thought to have.

why does the bitcoin wallet page saying using mycellium relies on the trust of a third party?

aren't the private keys controlled locally on the app? i.e. no trust in a third party involved

did you have the backups sent to your email?

if you did then it was possible your email account was compromised and the wallet password was simply brute forced.

You could check the balance of each public key manually at blockchain.info, but the least effort is probably just load Bitcoin-QT.

i ended up manually sweeping all the private keys into my blockchain.info wallet.

found 1.014 BTC! not much but i'll take it

This is how people can get into trouble with paper wallets - they think of it as an account with a balance.  You have to deal with the change or bad things happen.

thanks for the detailed write up, can i ask for an example of what you mean by this last statement? my friend keeps all his btc in paper wallets and spends exclusively from that. i told him it'd be better to keep a paper wallet just for long term storage and use and encrypted wallet with backups on his pc or just open a blockchain account and backup from there, but i couldn't give him a good example of why he shouldn't spend from paper wallets like they are bank accounts....

help -- importing old wallet
by
leshow
on 06/01/2014, 00:27:28 UTC
i was into bitcoin in 2011 and recently found an old hard drive, i thought i had spent all my old coins... but for interests sake i ran wallet-recover (https://bitcointalk.org/index.php?topic=25091.0)

and to my surprise found 198 public/private key pairs. i now have those in a wallet.dat. i'm interested to see if i actually have any money in it (kinda hope i do, but for the life of me i cant remember)

i don't have bitcoin-qt. is there any other method to import the wallet into something like electrum or multibit?

so you htink the FBI is going to make an account on Mt Gox or Bitstamp and sell their coins... seriously?

First of all they can't do anything until the trial is over. Secondly if they are going to sell them it isn't going to be on a japanese exchange that you can't withdraw any USD out of, or on an exchange whose bank is in slovenia. use your critical thinking skills...

Leshow, I've found the service very reliable, but if you've already rolled your own you might consider running it on an Amazon EC2 instance (or whatever other provider you prefer) if your issue is simply keeping processes alive.

i think i'd have to rewrite it for the ichimoku strategy, it seems to be getting much higher returns in backtesting

anyone know how to fix this problem?

cudaminer 2013-12-10 has a fix for validation issues on Kepler devices

Furthermore I suspect K14x16 requires more memory than the WDDM graphics driver model will allow on your system. cudaminer 2013-12-10 will print a warning if this happens.
Try one of these
a) don't use -C 1 (allowing the card to make a bunch of small memory allocations instead (i.e single-alloc: 0)
b) use a smaller launch config than K14x16. e.g. K14x8
c) upgrade your system RAM (e.g. to 4 GB or 6 GB), allowing larger memory allocations
d) Linux and Windows XP don't have the trouble with the WDDM driver model at all. Switch if you can.
e) autotune for the best launch config on your system instead of doing copy&paste from someone else's config

im on archlinux actually, and i have 8gb of ram... so that shouldn't be an issue. ill give the new settings a shot

i've been on your pool for about 6 months, but the last week or so when i get home I notice my workers are at 0 MH/s. when I restart them, they go back to their usual rate, then in a few hours they stop getting blocks again and go back to zero, so I have to keep manually restarting them in order for them to continue mining.

I tried api and api2 urls and it has made no difference. is anyone else experiencing this issue?

that's strange because my older version of phoenix ran by using ./phoenix.py .... but you're right that worked. thank you.


i don't know if this is related but in my old phoenix folder phoenix.py is colour coded, yet from the new download it's not (just standard white in the terminal).

in any case thank you.
