How we find, block, and prevent cryptomining at CircleCI
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.

Best Bitcoin Mining Software
A technician works at the Bitfarms bitcoin mine in Magog, Que. As the price of bitcoin soared over the past 14 months, Hut 8 was suddenly swimming in far more revenue than it ever had, opening up new doors for one of the oldest and largest digital asset miners to innovate, Ms. Leverton told The Globe and Mail in a recent interview. Many have seen their stock prices skyrocket, revenue and profits soar, prompting a healthy inflow of capital that is subsequently deployed into various new ventures in the cryptosphere. In a way, the maturation of crypto miners makes sense — it corresponds to the explosive, unbridled growth of anything associated with blockchain technology, a mania that some have previously termed speculative, geared just for the rich , and even worthless. Regulators grapple with growing world of cryptocurrency lending. Toronto fintech company Ledn Inc. Shares of Bitfarms , which trade on the TSX Venture Exchange, have risen about per cent this year, and in June, the company received approval to begin trading on the Nasdaq. The reason why bitcoin miners are able to expand and innovate their businesses is directly related to the price of bitcoin.
Bitcoin created a lot of buzz on the Internet. It was ridiculed, it was attacked, and eventually it was accepted and became a part of our lives. However, Bitcoin is not alone. At this moment, there are over AltCoin implementations, which use similar principles of CryptoCurrency. At this moment, there are over AltCoin implementations, which use similar principles and various cryptocurrency algorithms.
