Bitcoin cold storage - HACKED easily

[sgravina]

If it is easy then give it a try.

This attach won't work if the input address is not reused.  It gives the hacker the input private key but if that address is spent in the transaction and not reused then it can't be spent again by the attacker.

A simpler version of this attack would be to give the user a wallet which generates knowable private keys.  The attacker then watches all of addresses he has victims generate until he finds bitcoins.  This would work with any wallet the attacker was able to distribute.  Has this been attempted before?

it was proved that the COLD wallet can be hacked. once you are hacked, you cannot recover the bitcoin.

Yup, and normal people can easily pick up a handful of moondust, provided NASA takes them to the moon first.

or they can think : why would I use Bitcoin when I have fiat currency and other payment processors?

Yes, I can use Bitcoin to speculate a bubble but nothing more.

Now you're cooking!

Why use Bitcoin when you can use fiat.



Oh...you can get robbed at gunpoint...nevermind.


Oh yea, but we can use payment processors like credit cards AMEX, VISA, and Mastercard right?

Maybe go shopping at Target and...WHAT?!!?







Man that shit's no joke.

Damn I though you had a compelling reason, mayax, but just like this thread, very misleading...

[jonald_fyookball]

OP mostly FUD but good that people are aware of all the attack vectors.  
Can't be too careful when it comes to large amounts of money.

If you are using electrum, I have published several utility
scripts in the electrum sub forum that you can use
to verify if the addresses and keys from your copy
of electrum are legit.

 how can normal people use such script?  the normal people wants something safe and simple.

it was proved that the COLD wallet can be hacked. once you are hacked, you cannot recover the bitcoin.

I don't have all the answers...  I assume that in the future, as
cryptocurrency becomes more popular, people will know how
to do basic things like run python scripts, similar to how most
people know how to check the oil in their car... Either that
or hire a trusted security consultant.

Very tired of the vilification of Russian everywhere! The hackers and enemies of Bitcoin live in the good old US of A!

Do you deny they invented Tetris? Well then, hackers everywhere

There seems to be a lot of confusion in this thread about what is actually cold storage

[infobel]

Idiotic article/thread...

You can't actually call a not-"cold" storage, a cold storage.

Or, I can use Bitcoin just because I can, without making some old fat fart very reach for processing my Western Union transfer and taking tons of money as a fee for transferring some bytes of data over the internet.
Stop being so stubborn. I just bought 2 Steam Gift Cards with Bitcoin, just because I can, and I'm not giving my credit card information or personal information all over the internet for some small thing like those.

YOU on the other hand are the one using Bitcoin just to speculate, right now you're also very angry cause you're not rich already.

You should try using Bitcoin, it feels nice.

What steps should people take to make sure you are 100% safe when dealing with cold storage?

[cryptworld]

I'd like to get a word from a person with knowledge,  is this really dangerous for bitcoin, or is just a theoretic xploit impossible to make real?

get an offline wallet maybe with good antivirus and security.
only this can u do ?

No such thing as "100% safe" in computer security, but this gets you close as possible IMO.

1. Only use hardware that has never been connected to the internet and never will be.

2a. Only use trusted wallet software

2b. even safer:  ...that you compiled yourself from source and compared the executable hash to PGP signed executables

2c. safer still: ...that you also code reviewed.

3. bonus paranoid security:  use dice, coins, or cards to generate the entropy yourself rather than relying on the computer for randomness.

[Q7]

I think it makes complete sense to use only wallet that you trust is safe. If you are using android system and just a quick browse on google play using "bitcoin wallet" keyword, you will find a long list of wallets. Some are yet to be submitted to github, so that is the first warning bell.

If cold storage isn't safe then where do we store our coins securely?

0 Kelvin storage, of course

What's 0 Kelvin Storage? Never Heard of it before!

Well, it's sarcastic. 0 Kelvin is the coldest temperature posible:

Lol i thought it was some wallet system and googled it 

[ranochigo]

The chances of a cold storage getting hacked is fairly low if you compile it yourself, use trusted wallet software's and don't download any suspicious software. Remember to review source code and download from the trusted source and you will be fine.
