Bitcoin Mining is Bad for the World: The Limited Options for Addressing the Problem
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.

Why I will never buy Bitcoin (or any other cryptocurrency)
Every day, your web servers are increasingly being scanned—and likely attacked—by adversaries attempting to gain access to your infrastructure. Between and , our data partner, Loryka, observed these types of scans grow from per minute to as much as 2, per minute. These kinds of attackers are professionals; they do this for a living. Their goal is to make a profit in any way possible, usually by stealing data—credit card information, social security numbers, confidential business documents, user login credentials, to name a few—that they can sell on one or more Darknet trading markets. In other cases, attackers are paid by a third party to inflict damage to your website or disrupt service. Either way, the majority of exploitative attacks are designed to produce revenue for attackers.
Coin miners
There's also live online events, interactive content, certification prep materials, and more. Mining is the process by which new bitcoin is added to the money supply. Mining also serves to secure the bitcoin system against fraudulent transactions or transactions spending the same amount of bitcoin more than once, known as a double-spend. Miners provide processing power to the bitcoin network in exchange for the opportunity to be rewarded bitcoin. Miners validate new transactions and record them on the global ledger. Miners receive two types of rewards for mining: new coins created with each new block, and transaction fees from all the transactions included in the block. To earn this reward, the miners compete to solve a difficult mathematical problem based on a cryptographic hash algorithm. The solution to the problem, called the proof of work, is included in the new block and acts as proof that the miner expended significant computing effort. The process of new coin generation is called mining because the reward is designed to simulate diminishing returns, just like mining for precious metals.
Cryptojacking – Making You Mine!
Cryptocurrencies, once the exclusive domain of an idealistic fringe movement, have recently become attractive to mainstream retail investors. Cybercriminals are always looking for the path of least resistance to make money and cryptocurrencies are now in their crosshairs. Security researchers at the Lookout Threat Lab have identified over Android apps, including 25 on Google Play, scamming people interested in cryptocurrencies. Many of them available globally, these apps advertise themselves as providing cloud cryptocurrency mining services for a fee. After analyzing them, we found that no cloud crypto mining actually takes place.
How to Tell if you've Been Cryptojacked
Before a transaction is added to the blockchain it must be authenticated and authorised. There are several key steps a transaction must go through before it is added to the blockchain. The original blockchain was designed to operate without a central authority i. Each user has their own private key and a public key that everyone can see. Once the transaction is agreed between the users, it needs to be approved, or authorised, before it is added to a block in the chain. For a public blockchain, the decision to add a transaction to the chain is made by consensus.

Your computer could be quietly mining bitcoin — for someone else
A significant driver behind this sudden drop was news that China had begun a sweeping crackdown on the cryptocurrency industry, due to concerns about financial risk and excessive energy consumption. Before the clampdown, China accounted for two-thirds of Bitcoin mining worldwide. In the months since, mining companies have been quick to move their operations overseas. Bitcoin is a decentralised digital currency, meaning that each time money is sent or received, the transaction is kept on a public record, rather than with a bank.
