Dangers of cryptocurrency
We establish that cryptocurrency returns are driven and can be predicted by factors that are specific to cryptocurrency markets. Cryptocurrency returns are exposed to cryptocurrency network factors but not cryptocurrency production factors. We construct the network factors to capture the user adoption of cryptocurrencies and the production factors to proxy for the costs of cryptocurrency production. Moreover, there is a strong time-series momentum effect, and proxies for investor attention strongly forecast future cryptocurrency returns.

Risk In Bitcoin And Cryptocurrency Trading: A Financial Risk Expert Explains
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.

The tremendous surge in the price of cryptocurrencies has attracted the attention of many investors, who may be considering the digital currency as a potential substitute for traditional asset classes in diversified portfolios. A cryptocurrency is a digital or virtual means of exchange. Unlike traditional currencies, virtual currencies currently operate without central authorities or banks, and they are not backed by any government. Cryptocurrencies are stored in "digital wallets" on a holder's computer or phone, or in the cloud. The wallet serves as a virtual bank account that enables holders to pay for goods and services or simply store the currency in hopes of an increase in value.
The dangers to cryptocurrency wallets and how to fend them off (part 2)
The world is trying to understand what to do with the newly popular cryptocurrencies that have emerged. All sorts of investors jumped in to speculate on their future — a theme that repeats itself. A cryptocurrency is a type of digital token or asset designed to work as a medium of exchange that relies on cryptography i. They rely on peer-to-peer networking and decentralization. Besides, Bitcoin, there are nearly 1, other types of cryptocurrencies today, with two dozen the most actively used. For the blockchain to work, transactions must be validated each step of the way. This early work was done by cryptography enthusiasts thus the name. For their efforts, they earn cryptocurrency themselves.
Russia’s central bank proposes ban on crypto mining and trading
That cryptocurrency you just bought is as vulnerable to hackers as your smartphone or any other digital device, security experts are warning. Virtual — and increasingly popular — currencies like bitcoin, Ethereum, and Litecoin are unregulated and volatile, making them not just a high-risk investment, but criminals can break into crypto exchanges, drain crypto wallets and infect individual computers with malware that steals cryptocurrency.

The young are driving the cryptocurrency growth, unmindful of the dangers
Because cryptocurrencies are a relatively new breed of digital currencies, regulations are being drafted along the way, so there is always the potential for risk. Not to mention a high degree of uncertainty around how local regulators will respond to crypto in the future. Cryptocurrencies exhibit highly volatile price movements. The risk of loss in trading or holding cryptocurrency can be substantial. If you are in any doubt about cryptocurrencies or the action you should take, we recommend you seek financial advice including but not limited to tax from an appropriately authorized and independent financial adviser.
Bitcoin had a wildly volatile first half. Here are 5 of the biggest risks ahead
This growth can largely be attributed to the many lucrative, high-interest earning opportunities available across DeFi lending and trading platforms. DeFi protocols are blockchain-based platforms that offer a range of financial services you would typically find in the traditional space, such as:. The key difference is, DeFi platforms run entirely using smart contracts rather than having an intermediary like a bank or insurance broker operating in the middle. Smart contracts are self-executing computer programs that enforce contractual agreements between parties. In an ideal world, they power valuable non-custodial financial services, like lending protocols and decentralized exchanges. But sometimes they contain bugs or gaping security vulnerabilities that allow attackers, or even errant developers, to drain treasury wallets. Free tools, such as Token Sniffer for Ethereum and PooCoin for Binance Smart Chain, run automated audits of token contracts to check if they contain any malicious code for you.
What are the risks of investing in cryptocurrency
Even those who are most suspicious of the rise of cryptocurrency will likely admit that the underlying blockchain technology and its potential uses are exciting. One use of this technology, decentralized finance, or DeFi, is on the cusp of major growth. Regulators are aware of this growth and are moving to act accordingly.

In part one of this blog , ESET explored some of the threats surrounding the use of hot wallets; specifically clippers and fake login pages. These threats are particularly lethal due to the fact that hot wallets are always connected to the internet. Here, we continue our overview of the cryptocurrency wallet threat landscape, by taking a look at malware-laced links as another top danger to hot wallet users, along with some security considerations relevant for cold wallet users. This is called a homoglyph attack. By replacing certain characters in the domain name with ones that, to human eyes, either look similar or identical but are actually different to computers , phishing operators can craft links that appear to lead to popular websites but actually resolve to malicious sites.
