Bitcoins hackable websites

Like everything else of value running on computers, bitcoin, other cryptocurrencies, and blockchains have come under frequent successful attacks. Hundreds of millions of dollars have been stolen, people have been cheated, and blockchains ripped off. Here are some of the hacks:.

Each mined bitcoin makes future bitcoins harder to create. Electricity is the number one operational cost to a bitcoin miner. Today, many of the biggest malware botnets are simply to mine bitcoin. It also slows down the hijacked computers. You stop bitcoin miners like you do any other malware program. Crypto-currencies often store their value in file stores known as wallets.

Wallets can be compromised, manipulated, stolen and transferred, just like any other store of value on a computer. Ransomware can cause the same issue. With a regular bank account, you can just use another computer to access your online account where your value sits untouched.

Not so with wallets. This can also make it harder to use that value. The offline nature can add days of waiting to use or update the value store. If you use an online wallet, protect it with multi-factor authentication if possible. There are crypto-currency trojans that sit monitoring your computer waiting for what looks like the format of a crypto-currency account number. When it spots one, it comes awake and replaces the intended account you are transferring value to with their account number.

Unless you are very aware of the switch, it will be game over if you hit the Send button. In practice, there is. Like any crypto implementation, the cryptologic algorithm is almost always far more sound than the program that implements it. In general, blockchaining suffers from any vulnerability or weakness that you might subscribe to any cryptographic solution.

A programming bug or lack of good private key security or bitcoin wallets can bring the whole thing down. There have been instances where hackers manipulated the crypto-currency software to steal value. Good crypto makes the resulting cryptotext look like random gibberish.

Theoretically, a crypto-attacker should not be able to figure out what the original plaintext looked like. With any blockchain technology, however, the format of the blocks is fairly well known or easy to figure out. Certain letters, characters, or numbers are always in the same places in every block. Plus, every block is a function of the previous block. This weakens the overall protection of the underlying encryption cipher.

Many security experts wonder if SHA, which contains the same mathematical weaknesses as its shorter, very much related SHA-1 precedent, is a concern for bitcoin and blockchain both usually use SHA The answer is not right now. SHA is strong enough for the foreseeable future. One of the most common hacking threads surrounding bitcoin, but can be applied to any blockchain project, is how often the centralized website controlling it gets hacked. Far too many crypto-currency sites managing tens to hundreds of millions of dollars have been successfully hacked.

When that happens, the bitcoin value people have built often disappears into the ether. Make sure to back up your value into an offline location. Some of the biggest hacks have been ascribed to unscrupulous operators who run away with millions in ill-gotten gains. Make sure if you do business with a crypto-currency web site that the site is well secured and trustworthy. The FDIC is not going to bail you out if you lose your deposits, at least not yet.

The most lucrative attacks are carried out on online services that store the private keys for a large number of users, as Sheep Marketplace did. Just copy the database of private keys and you can gain control of the bitcoins at all those addresses. While Bitcoin has some features that make it great for thieves, it also has some features that make it not so great.

The fact that the blockchain is public means that anyone can see to which address the coins were transferred next. After the Sheep Marketplace heist, some users tracked the thief as he or she moved the stolen coins from address to address. However, Bitcoin forensics is getting better and better as programmers figure out new ways to extract information from the blockchain.

A thief may leave traces that are undetectable now but could be uncovered in the future, inspiring a retroactive investigation. Most of the time it works basically like this: you transfer your stolen bitcoins to a new address owned by the Bitcoin tumbler. Anyone watching would probably notice if the same exact amount of bitcoins — say, When you request 10 bitcoins, the tumbler will transfer 10 bitcoins to your clean address.

Extra-careful tumblers may also split these payouts further, especially if it is a noticeably large number of bitcoins. The tumbler is only accessible through the anonymizing Tor network, making it difficult for law enforcement to trace traffic to it or discover the people behind it. Of course, that also means you have to trust the tumbler.

As such, if the mixing output fails to be delivered or access to funds is denied there is no recourse. Another option is to launder the money the way the mob might: spend it at Satoshi Dice or another Bitcoin casino. Like most merchants in the world, she wants a government-sanctioned currency, preferably the euro. It also becomes much harder to conceal your identity when you exchange Bitcoin for other currencies.

Most exchanges require some type of identifying information, and at the very least you need an account into which the euros can be deposited. There are several ways you can unload a lot of Bitcoin while maintaining your anonymity. Find a rich buyer who is willing to take the bitcoins without verifying your identity in exchange for a discount on the price, for example. However, the best way to protect yourself is to remain patient. Unload your bitcoins in a series of transactions over weeks, ideally months or even years, in order to avoid arousing suspicion from those watching the blockchain as well as real-life authorities that might wonder how you suddenly came into millions of dollars.
