Hacking bitcoin and blockchain | CSO Online

In , he generated the first block of blockchain and software that anyone could download and cryptographically generate i. The author of this article downloaded the software during the first few days and quickly generated three bitcoins. The substantial, rapid price increase has gotten the attention of investors and financial sector corporate CEOs, although not usually with affirmation. The way bitcoin, the software, and the distributed network is created, each slew of newly generated bitcoins makes it incrementally harder to generate the next bitcoin.

Today, it takes so much electrical energy to generate bitcoins that the measures are compared to total global electricity use on a regular basis. By design, it takes not only a huge amount of computing power to create a bitcoin, but also, even though not in the same realm of effort, a lot of computational effort to create and validate a bitcoin transaction. Eventually, a maximum of 21 million bitcoins will be mined by This self-induced crypto-scarcity is part of what is fueling bitcoin's stratospheric price rise.

While investors and financial experts fight over the value of bitcoins, no one is arguing over the value and legitimacy of blockchain. You can create and use blockchains in the cloud or within your own private business. Companies promoting blockchain see a day when nearly every financial transaction is backed by a blockchain. Blockchaining can make very complex financial transactions solvable in seconds.

One multi-national bank blockchain leader Credit Suisse on CNBC television said that the average leveraged buyout deal takes a month to finish financially. Using blockchains, he estimated the closing would take a few seconds. He told viewers to imagine how much more efficient blockchaining could make every complex transaction, freeing up workers and capital to be more productive. Nearly every industry heavy with financial transactions, is rushing to find out how to implement blockchain within their businesses and industries.

You name the sector, and blockchain is the hot topic. Computer industry cloud giants, like Microsoft and Amazon now offer myriad blockchain services. Bitcoin may be in a bubble, but blockchain is on its nascent rise and here to stay. Early on, many bitcoin and blockchain enthusiasts wondered if the inherent crypto nature of both was sound enough to withstand constant hacking.

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.
