Can Texas’ Power Grid Withstand Cryptocurrency Mining?
By Josh Grunzweig. Category: Unit As time progressed, I began asking myself it this was a coincidence, or part of a much larger trend. In doing so, I found a radical upward trend. The graph below represents how many new cryptocurrency mining malware samples have been identified over time.
This realization of this trend was only the start, however, as I wished to analyze this entire dataset to answer some of the following questions:.
Starting in roughly June , Bitcoin and other top cryptocurrencies saw a dramatic rise in their value, as more and more people sought to invest, which ultimately drove up the price. Coincidentally, June is also when we began to witness the trend of a high uptick in cryptocurrency miners within the WildFire platform.
This blog represents and overview of my research to answer these questions, and the results I was able to discover. General Statistics To date, I have identified roughly , unique samples that ultimately deliver cryptocurrency miners.
Using WildFire reports and associated PCAP data, I was able to analyze these samples to parse out various information, which included some or all of the following:. When looking at a breakdown of what cryptocurrencies are being targeted by mining malware, we see an incredible monopoly of the Monero cryptocurrency. Figure 3 Breakdown of cryptocurrencies targeted by malicious miners. Monero Statistics I extracted a total of 2, Monero wallets from the analyzed sample set.
This is by design: a result of how Monero was originally designed. As such, I needed to take a different methodology in order to determine how much money attackers were able to mine. Fortunately, in addition to the wallets, I was also able to determine which mining pools were used for various mining efforts. Looking at the top ten mining pools used by this malware, I determined that all but one allows for anonymous viewing of statistics based off of the wallet as an identifier.
This anonymous viewing is intentional, as it allows users to anonymously connect and use various mining pools without inputting any personal identifiable information. Figure 4 An example of anonymously querying a mining pool for information on a XMR wallet. By querying the top eight mining pools for all 2, Monero addresses, I was able to determine exactly how much Monero has been mined historically with a high degree of accuracy.
We used the following Monero pools for this research:. By querying these addresses against these mining pools, we obtained the following statistics on how many Monero coins have been mined to date:. As such, we can assume that the actual percentage of Monero in circulation that was mined via malicious activity is actually higher. Looking at the overall distribution of wealth among the 2, wallets identified proves to provide interesting insight. Nearly half of all the wallets identified have been unable to generate any meaningful amount of Monero, likely due to the malware being unsuccessful, or the attacker using a mining pool other than the ones queried.
Figure 7 Distribution of Monero mined to wallets earning 0. Only wallets of these wallets have earned XMR or greater. Additionally, only 99 wallets have mined over 1, XMR, which represents 7. Finally, 16 wallets have obtained over 10, XMR, which represents 1. Based on this spot check, we have the following figures:. In the graph below, we discover a consistent upward and downward trend that takes place once a day.
It is not fully clear why this change occurs on a daily basis, but it is consistent in a number of other malicious cryptocurrency miners encountered. One hypothesis for why this activity may be occurring is that the malware may be configured to only operate at given times of the day, or when the user is not active on the system. Alternatively, perhaps the victims are concentrated in a specific geographical region, and this upward and downward flow is simply a result of users shutting off their machines in the evening hours.
Looking at the top miner based on hashrate shows an interesting depiction:. In addition to seeing the same wave pattern as the first example, we also notice that the activity for this miner is fairly recent, beginning in early April of this year.
In addition to the upward and downward flow, we also encounter wallets that have a much more consistent mining capacity. This is very similar to activity you might encounter by a benign cryptocurrency miner, which makes it difficult to easily identify.
Conclusion To date, the popularity of malicious cryptocurrency mining activity continues to skyrocket. The large growth of malware mining cryptocurrencies is a direct result of a previous spike in value, which has since corrected to a value that is more in line with expectations. As this correction has taken place, only time will tell if cryptocurrency miners will continue in popularity.
It is clear that such activities have been incredibly profitable for individuals or groups who have mined cryptocurrency using malicious techniques for a long period of time. Defeating cryptocurrency miners being delivered via malware proves to be a difficult task, as many malware authors will limit the CPU utilization, or ensure that mining operations only take place during specific times of the day or when the user is inactive.
Additionally, the malware itself is delivered via a large number of methods, requiring defenders to have an in-depth approach to security. Palo Alto Networks customers have a number of means to combat this threat on their networks, including Traps and Wildfire detections for cryptocurrency miners delivered via malware. Additionally, the stratum App-ID may be used to identify cryptocurrency mining activity and take appropriate actions on it. Readers may refer to the following list of all XMR wallets identified during this research.
This realization of this trend was only the start, however, as I wished to analyze this entire dataset to answer some of the following questions: What cryptocurrencies are mined the most?
How much money has historically been made by these actors? Using WildFire reports and associated PCAP data, I was able to analyze these samples to parse out various information, which included some or all of the following: Cryptocurrency targeted Wallet and email addresses used when connecting to mining pools Mining pool This ultimately led me to collecting the following high-level information: , Samples 3, Emails used to connect with mining pools 2, mining pool URLs 2, Monero XMR wallets Bitcoin BTC wallets Electroneum ETN wallets 44 Ethereum ETH wallets 28 Litecoin LTC wallets When looking at a breakdown of what cryptocurrencies are being targeted by mining malware, we see an incredible monopoly of the Monero cryptocurrency.

How to Mine Cryptocurrency? Full guide 2022
Until two months ago, cryptocurrency mining mainly occurred at farms like this one in China seen in March. But since then, China has called for a severe crackdown on Bitcoin mining because it was creating energy shortages that were forcing the country to fire up dirty coal plants. Then, just two weeks ago, Swedish officials sent an open letter to the European Union asking it to ban bitcoin mining throughout Europe. The result has been a massive migration of Bitcoin mining to the U. From May to July alone, the U. And that number is only increasing. How does Bitcoin work?
Summer on Seneca Lake, the largest of the Finger Lakes in upstate New York, is usually a time of boating, fishing, swimming and wine tasting. But for many residents of this bucolic region, there's a new activity this season — protesting a gas-fired power plant that they say is polluting the air and heating the lake. They have increased the electrical power output at the gas-fired plant in the past year and a half and use much of the fossil-fuel energy not to keep the lights on in surrounding towns but for the energy-intensive "mining" of bitcoins. Bitcoin is a cryptocurrency — a digital form of money with no actual bills or coins. The computers earn small rewards of bitcoin by verifying transactions in the currency that occur on the internet around the world. The math required to verify the transactions and earn bitcoins gets more complex all the time and demands more and more computer power. An estimate from the University of Cambridge says global bitcoin miners use more energy in a year than Chile.

Representations of the Ripple, Bitcoin, Etherum and Litecoin virtual currencies are seen on a PC motherboard in this illustration picture, February 14, The move is the latest in a global cryptocurrency crackdown as governments from Asia to the United States worry that privately operated and highly volatile digital currencies could undermine their control of financial and monetary systems. Russia has argued for years against cryptocurrencies, saying they could be used in money laundering or to finance terrorism. It eventually gave them legal status in but banned their use as a means of payment. The bank proposed preventing financial institutions from carrying out any operations with cryptocurrencies and said mechanisms should be developed to block transactions aimed at buying or selling cryptocurrencies for fiat currencies.
What is Cryptojacking? – Definition and Explanation
Engineers on a cherry picker inspect mining rigs at the CryptoUniverse cryptocurrency mining farm in Nadvoitsy, Russia, March 18, Russia's central bank proposed on Thursday banning the use and mining of cryptocurrencies on Russian territory, joining the latest wave of global cryptocurrency crackdown. In a report published on the day, the central bank said speculative demand primarily determined cryptocurrencies' rapid growth and that they carried characteristics of a financial pyramid, warning of potential bubbles in the market, threatening financial stability and citizens. The central bank, which is planning to issue its own digital rouble, said crypto assets becoming widespread would limit the sovereignty of monetary policy, with higher interest rates needed to contain inflation. Governments from Asia to the United States have expressed worry that privately operated and highly volatile digital currencies could undermine their control of financial and monetary systems.

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.
Russia's central bank on Thursday proposed banning the use and mining of cryptocurrencies on Russian territory, citing threats to financial stability, citizens' wellbeing and its monetary policy sovereignty. The move is the latest in a global cryptocurrency crackdown as governments from Asia to the United States worry that privately operated and highly volatile digital currencies could undermine their control of financial and monetary systems. Russia has argued for years against cryptocurrencies, saying they could be used in money laundering or to finance terrorism. It eventually gave them legal status in but banned their use as a means of payment.
The Bitcoin network is burning a large amount of energy for mining. In this paper, we estimate the lower bound for the global mining energy cost for a period of 10 years from to , taking into account changes in energy costs, improvements in hashing technologies and hashing activity. We estimate energy cost for Bitcoin mining using two methods: Brent Crude oil prices as a global standard and regional industrial electricity prices weighted by the share of hashing activity. Despite a billion-fold increase in hashing activity and a million-fold increase in total energy consumption, we find the cost relative to the volume of transactions has not increased nor decreased since This is consistent with the perspective that, in order to keep the Blockchain system secure from double spending attacks, the proof or work must cost a sizable fraction of the value that can be transferred through the network. Bitcoin is a digital currency launched in by an anonymous inventor or group of inventors under the alias of Satoshi Nakamoto Nakamoto,
Cryptocurrency mining refers to the process of verifying and validating blockchain transactions. Honest and successful miners are rewarded for their work with newly created cryptocurrencies plus transaction fees. Mining is the process in which cryptocurrency transactions between users are verified and added to the blockchain public ledger.
