How to protect your computer from mining bitcoins
Bitcoins are created through a process called mining. Mining involves using lots of processing power to solve mathematical problems for rewards: 6. At the current price, mining can be very profitable for those with the hardware in place, or for people who contribute their personal processing power to a larger mining pool, where they can collaborate with others and receive a portion of the reward when a block is solved. These are two conventional methods of mining Bitcoin but a third, shadier practice exists — hijacking processing power from unsuspecting computers.

With the establishment of cryptocurrency, the era of a new means of payment has been ushered Crypto Mining in. We started with Bitcoin, which was first described in by the Japanese Satoshi Nakamoto in the Bitcoin white paper. His idea: The establishment of a digital currency. This should be organized decentrally, i.
The maximum number of Bitcoins should be limited to a total of 21 million, in order to exclude inflation from the outset. Unlike central banks, however, Bitcoin units are not printed like banknotes, for example, but can only be generated digitally by computing power.
These are then lined up in a linear sequence and linked together via a decentralized peer-to-peer network. The check number in turn contains the individual hash values of the current transaction as well as the hash values of the respective previous transaction.
Thanks to this procedure, manipulation of the transactions is impossible, since a subsequent change within the chain would not only stand out, but is not even mathematically possible. If only one value were to be manipulated, the subsequent value would also deviate from the actual sequence.
Simply explained, there are two different possibilities to mine cryptocurrency. These are private crypto mining from home and crypto mining via the cloud. The two possibilities will be examined in more detail below:. The foundation stone for every type of crypto mining is the so-called eWallet, which is used to store the cryptocurrencies generated during mining e. Bitcoins, Moneros and Co. In addition, private Bitcoin Mining requires a special program that can execute the hash function for mining.
This can be installed and set up quite easily by any PC owner. Although it is still possible to run Crypto Mining from home with the CPU of your own computer, it is not recommended nowadays for economic reasons. But even this is not always profitable compared to crypto mining via the cloud. If you want to save yourself the trouble of operating Crypto Mining from home, you can rent hash services from a cloud mining provider. Meanwhile there are countless different providers, some of which operate entire mining farms.
The contracts can be concluded for different crypto currencies via the website of the respective provider. The costs of the contracts depend on the rented service. Thus the providers remain independent of the value of the cryptocurrencies. Crypto Mining is an extremely complex, resource-intensive — and therefore expensive — process. While in the early days of Bitcoin and Co. This ensures that from a certain point in time it is twice as time-consuming to generate a unit of a crypto currency.
This measure is necessary because otherwise inflation would occur. Conversely, this means that more and more computing power is required to generate the unit of a cryptocurrency. The power consumption and the wear and tear on the hardware are increasing rapidly.
Resourceful Crypto Miners soon began looking for new ways to mine crypto currencies more profitably. Completely new possibilities quickly established themselves: One is the mining of cryptocurrencies in countries with very low energy prices, such as Iceland, Venezuela or Georgia. Entire industries have already developed in these countries, some of which are now a problem for the stability of the national power supply. Iceland has already experienced an energy shortage due to the rapid increase in crypto mining activities.
The consequences: A significant shortage of the sought after commodity and increasingly expensive production An almost free, but also illegal method is the generation of cryptocurrencies with the help of a botnet.
The aim here is to make as many computers as possible part of such a network and have them mine crypto currencies in a network. How the criminal miners succeed in this is described below.
However, the legal situation is anything but clear. Some of them even use the full CPU power, such as the Crypto Mining program that was included on the website of Portuguese football star Cristiano Ronaldo. But this method has a decisive disadvantage for Coinhive users: Cryptocurrencies are only mined as long as someone is actually actively on the website.
If they leave the site, the crypto mining process is aborted. Crypto mining using malware is a completely different matter. This method uses malware specially designed for mining cryptocurrencies. The cybercriminals use different ways to smuggle it onto the computers of their victims. The most popular method of distribution is via infected websites. But pirated software is also suitable as a hiding place for a crypto mining dropper. If a user calls up an infected download website, the malware is loaded onto the computer unnoticed via a drive-by download and begins to dig up a selected crypto currency for the hackers.
Since the maximum computing power of the devices is to be used to the full, the cyber criminals must proceed with caution in order not to be discovered while digging. Because if the device is always running at percent computing power, it can hardly be operated by its owner. In most cases, the user will then take countermeasures. As a result, Crypto Mining Malware usually uses only about two thirds of the computing power. Crypto Mining Malware has even been detected that is able to bypass antivirus programs.
However, many independently infected devices do not yet give cybercriminals much use. The important thing is that they can bundle their power to mine crypto currency. A bot network is the ideal tool for this. Some of these networks comprise several thousand computers, and the profits that cybercriminals make are correspondingly high.
On the one hand, it is important to understand how cyber criminals proceed in illegal crypto mining and what tools they use. The right security awareness can lay the foundation for effective prevention. As a supplement, an anti-virus program should be installed on the computer, which is always kept up to date — this naturally also applies to all other programs and the operating system.
If you want to download software from the Internet, you should only do this via trustworthy sources such as heise. Renowned download portals also offer software for download that wants to install additional software during the installation process. It cannot be ruled out that this may contain additional malware such as crypto mining droppers. Furthermore, spam e-mails may also contain links that lead to websites contaminated with Crypto Mining Droppers.
As it can be difficult to distinguish well-done spam e-mails from normal e-mails, it is recommended that companies in particular use a managed spam filter service.
Increased attention is also advised when surfing the web. Since dubious, malware-infected pages are of course only rarely recognized as such, the use of a web filter is also recommended.
This reliably warns the user of potentially harmful content before calling up the page. This provides protection not only against Crypto Mining Malware but also against all other harmful content. Did you like our contribution from the knowledge database on Crypto Mining?

Quantum computers and the Bitcoin blockchain
Podcast Safety Tips. Cryptocurrency enthusiasts are flocking to the Wild West of Bitcoin and Monero to cash in on the recent gold rush. Some coin miners , also known as cryptocurrency miners, are tempted by the dark side of the industry and resort to nefarious means to harness the immense computing power needed for cryptocurrency profits. Greedy cryptocurrency criminals employ a practice called cryptojacking , steal ing the computer power of unsuspecting devices to help them mine faster. Y our device could be at risk at being recruited to their efforts. Mining cryptocurrency takes a lot of time and computer processing power. Once the software is installed, t he rig is ready to mine , running mathematical calculations to verify and col lect new cryptocurrency transactions.
But, as with most things Bitcoin, this interpretation is based more on hope than fact. Bitcoin has failed to live up to the hype that it would democratize finance by enabling cheap, instantaneous, and secure payments that could be conducted without having to rely on stodgy old financial institutions like banks and credit card companies. Bitcoin has failed to meet this vision due to its excessive price volatility, slow transaction processing, difficult user experience e. Some have even questioned whether bitcoin has any social value at all. Rather than being a viable currency at scale, Bitcoin is and will remain a speculative asset, in a class with gold, tulips, and Beanie Babies. Unlike these other assets, however, Bitcoin introduces unique risks and harms. Because of the pseudo-anonymity it provides, Bitcoin has become a vehicle for illicit finance—though it still plays a much smaller role than anonymous cash. Recent estimates of the energy used by Bitcoin mining range from about 75 Digiconomist to University of Cambridge terawatt hours TWH per year.
4 Ways to Tell if Your Computer is Secretly Mining Cryptocurrency
Gold has miners because people want gold and it just so happens, unfortunately, that most gold is deep in the earth. Bitcoin has miners because people want bitcoins, but something here seems silly: how did a bunch of bitcoins, the tokens of a man made invention, end up locked up in circumstances demanding mining? When gold is mined, nothing is achieved beyond the discovery of new gold. When bitcoins are mined, however, a valuable service is provided to the Bitcoin network: decentralized transaction recordation and validation.

This usually occurs when the victim unwittingly installs a programme with malicious scripts which allow the cybercriminal to access their computer or other Internet-connected device, for example by clicking on an unknown link in an e-mail or visiting an infected website. As they are digital currencies, only computer programmes and computing power are needed to create cryptocurrencies. The type of cryptocurrency we see primarily mined on personal computers is called Monero. But the use of computing power for this criminal purpose is done without the knowledge or consent of the victim, for the benefit of the criminal who is illicitly creating currency. As a large number of infected devices generates a huge amount of cryptocurrency, cybercriminal see this as a lucrative crime. The primary impact of cryptojacking is performance-related, though it can also increase costs for the individuals and businesses affected because coin mining uses high levels of electricity and computing power.
Last week a number of tweets were sent criticising online security company Norton for installing cryptocurrency mining software without users' permission. And while it's true that Norton does install software that allows users to mine for cryptocurrency when their computer is idle, what was missed was this happened in the middle of last year. The news was first announced last June when Norton rolled out the feature to those in their early adopter programme and Norton for Gaming subscribers , including those in Aotearoa. The company has also updated its FAQ to confirm that mining doesn't occur without the user giving explicit permission.
Downpours transform the mottled landscape into lush emerald, while azaleas bloom and migrating cranes and storks begin the long journey back north. The rainfall also brings trucks stacked with computers to hydropower dams, where entrepreneurs can tap cheap electricity for mining bitcoin—the arcane process that accumulates the cryptocurrency using huge amounts of computing power to solve equations. Cryptocurrency mining requires huge amounts of computing power, making energy consumption a major overhead for the industry. Local governments will often offer power for pennies—or even free—to attract jobs and get a painless boost to their gross domestic product figures. While individual miners and traders may be able to slip through the cracks, larger commercial miners will likely be considering alternative mining hubs with less rigorous regulatory regimes, analysts say.
The popularity of cryptocurrency, a form of digital currency, is rising. However, many people do not understand cryptocurrency and the risks associated with it. Malicious cyber actors use cryptocurrency-based malware campaigns to install cryptomining software that hijacks the processing power of victim devices and systems to earn cryptocurrency.
