Mining bitcoin 101
That is an incredible ten-fold increase in less than a year, making it one of the most profitable investments of the decade. But what actually is Bitcoin, and does it have any real utility? Nakamoto created this digital currency as a way to transfer wealth through peer-to-peer computer networks instead of traditional centralized banks. This cut out the middleman, making bitcoin cheaper to transfer and more efficient. Bitcoin works on a blockchain, which is essentially a decentralized and immutable ledger—think of Google docs without needing Google.

Bitcoin 101: Back to Basics
The Australian government has just recognized digital currency as a legal payment method. Since July 1, purchases done using digital currencies such as bitcoin are exempt from the country's Goods and Services Tax to avoid double taxation.
As such, traders and investors will not be levied taxes for buying and selling them through legal exchange platforms. Japan, which legitimized bitcoin as a form of payment last April, already expects more than 20, merchants to accept bitcoin payments. Other countries are joining the bandwagon, albeit partially: businesses and some of the public organizations in Switzerland, Norway , and the Netherlands. In a recent study , unique, active users of cryptocurrency wallets are pegged between 2.
But what does the acceptance and adoption of digital currencies have to do with online threats? A lot, actually. As cryptocurrencies like bitcoin gain real-world traction, so will cybercriminal threats that abuse it. But how, exactly? What does this mean to businesses and everyday users?
Cryptocurrency is an encrypted data string that denotes a unit of currency. It is monitored and organized by a peer-to-peer network also known as a blockchain, which also serves as a secure ledger of transactions, e.
Unlike physical money, cryptocurrencies are decentralized, which means they are not issued by governments or other financial institutions. Cryptocurrencies are created and secured through cryptographic algorithms that are maintained and confirmed in a process called mining, where a network of computers or specialized hardware such as application-specific integrated circuits ASICs process and validate the transactions.
The process incentivizes the miners who run the network with the cryptocurrency. Bitcoin, for instance, was created by Satoshi Nakamoto pseudonym and released in as open-source code. Blockchain technology made it all work, providing a system where data structures blocks are broadcasted, validated, and registered in a public, distributed database through a network of communication endpoints nodes.
While bitcoin is the most famous cryptocurrency, there are other popular alternatives. This resulted in the development of Ethereum Classic, based the original blockchain, and Ethereum, its upgraded version via a hard fork. There are also other notable cryptocurrencies: Litecoin, Dogecoin, Monero.
Litecoin is a purportedly technical improvement of Bitcoin that is capable of faster turnarounds via its Scrypt mining algorithm Bitcoin uses SHA The Litecoin Network is able to produce 84 million Litecoins—four times as many cryptocurrency units issued by Bitcoin.
Monero is notable for its use of ring signatures a type of digital signature and CryptoNote application layer protocol to protect the privacy of its transactions—amount, origin, and destination. Dogecoin, which was initially developed for educational or entertainment purposes, was intended for a broader demographic. Capable of generating uncapped dogecoins, it also uses Scrypt to drive the currency along.
Given their nature, they are more secure from fraud and identity theft as cryptocurrencies cannot be counterfeited, and personal information is behind a cryptographic wall. Unfortunately, the same apparent profitability, convenience, and pseudonymity of cryptocurrencies also made them ideal for cybercriminals, as ransomware operators showed.
The increasing popularity of cryptocurrencies coincide with the incidences of malware that infect systems and devices, turning them into armies of cryptocurrency-mining machines. Cryptocurrency mining is a computationally intensive task that requires significant resources from dedicated processors, graphics cards, and other hardware. While mining does generate money, there are many caveats. Cryptocurrencies are mined in blocks; in bitcoin, for instance, each time a certain number of hashes are solved, the number of bitcoins that can be awarded to the miner per block is halved.
Since the bitcoin network is designed to generate the cryptocurrency every 10 minutes, the difficulty of solving another hash is adjusted. And as mining power increases , the resource requirement for mining a new block piles up. Payouts are relatively small and eventually decrease every four years—in , the reward for mining a block was halved to Consequently, many join forces into pools to make mining more efficient.
Profit is divided between the group, depending on how much effort a miner exerted. Bad guys turn to using malware to skirt around these challenges. To offset this, cryptocurrency-mining malware are designed to zombify botnets of computers to perform these tasks. Cryptocurrency-mining malware employ the same modus operandi as many other threats—from malware-toting spam emails and downloads from malicious URLs to junkware and potentially unwanted applications PUAs. In January , a vulnerability in Yahoo!
In , the threat crossed over to Android devices as Kagecoin , capable of mining bitcoin, litecoin, and dogecoin. The same was done to an old Java RAT that can mine litecoin. All exploit vulnerabilities. These threats infected devices and machines and turned them into monero-mining botnets. Cryptocurrency-mining malware steal the resources of infected machines, significantly affecting their performance and increasing their wear and tear.
An infection also involves other costs, like increased power consumption. The most prevalent of these attacks we saw were:. Information theft and system hijacking are also daunting repercussions. These attacks can also be the conduit from which additional malware are delivered. In April , a variant of Mirai surfaced with bitcoin-mining capabilities. Over the first three quarters of , we detected a bitcoin-mining zombie army made up of Windows systems, home routers, and IP cameras.
From January 1 to June 24, , we also observed different kinds of devices that were mining bitcoin, although our telemetry cannot verify if these activities were authorized. We found that machines running Windows had the most bitcoin mining activities, but also of note are:.
Cryptocurrency-mining malware can impair system performance and risk end users and businesses to information theft, hijacking, and a plethora of other malware. And by turning these machines into zombies, cryptocurrency malware can even inadvertently make its victims part of the problem. There is no silver bullet for these malware, but they can be mitigated by following these best practices:. Proactively monitoring network traffic helps better identify red flags that may indicate malware infection.
Original design and equipment manufacturers also play vital roles in securing the ecosystems they run in. Like it? Add this infographic to your site: 1. Click on the box below.

Bitcoin Mining 101
By now, you've likely seen the term "bitcoin" showing up all over your social media feeds and newscasts, and may be wondering what exactly this trending form of money is and why so many people have begun investing in it. Bitcoin is a form of money that is entirely digital. This type of currency is also known as cryptocurrency. Bitcoin was the first to launch, and now there are several competing cryptocurrencies, including Litecoin, Namecoin and PPCoin, to name a few. The U. That means no single nation, bank, or institution controls it.
How Bitcoin Mining Works
There are two primary reasons why a person, or company, would want to mine cryptocurrency like bitcoin. In order to validate and add new transactions to the blockchain, miners must compete with each other using specialized computing equipment. The target hash is a digit hexadecimal code comprising numbers and letters A-F all miners are trying to get below in order to discover the next block. Remember, just changing a single bit of the input produces a totally different hash. This is why miners have to invest in energy-intensive computers, particularly application-specific integrated circuit ASIC miners, that can generate trillions of hashes per second. An easy way to think of bitcoin mining is to imagine each new block is a treasure chest with a combination lock on it. To get the free bitcoin block reward inside and win the right to add new transaction data into it and collect the associated fees you have to keep turning one of the number wheels on the lock the nonce until you crack the combination the target hash.

As we saw last week, mining is necessary to confirm transactions so that the bitcoin network participants can transact with one another. Furthermore, bitcoin mining enables a fair issuance scheme for newly created bitcoin. At a predetermined rate embedded in the bitcoin source code , every new block contains some new bitcoin for the miner who finds the block. When Satoshi Nakamoto created bitcoin, the issuance rate was 50 bitcoin per block, halved every four years. This so-called "halving" occurs approximately every four years until all the 21 million bitcoin are issued.
