You, who have always been interested in mining cryptocurrencies and have even read our article on how to mine the Ethereum can be mining crypts without even knowing it.<\/div>\n<div><\/div>\n<div>How? Through cryptojacking, which is the unauthorized use of computers, tablets, cell phones or domestic devices by cybercriminals to extract cryptocurrencies.<\/div>\n<div><\/div>\n<div>Cyber-crooks can \u2018hijack\u2019 someone else\u2019s resources with just a few lines of code. This means that the victim has to bear the cost of the computing power and electricity costs required to extract cryptocurrencies, while the criminals take the prize.<\/div>\n<h2><span class=\"ez-toc-section\" id=\"how_does_cryptojacking_work\"><\/span><strong>How does cryptojacking work?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<div>Mining cryptocurrencies on your own can be a long and expensive job. High electricity bills and expensive equipment are the main investment and key challenges for coin mining.<\/div>\n<div><\/div>\n<div>The more equipment you have working for you, the faster you can \u201cextract\u201d cryptos. Due to the large amount of time and resources invested in crypt mining, cryptojacking is highly attractive to cybercriminals.<\/div>\n<div><\/div>\n<div>There are several ways in which this type of attack can occur. One of the most popular methods, which we discussed in our article on how to avoid scams, is to use malicious emails that can install encrypted mining code on your computer.<\/div>\n<div class=\"is-divider divider clearfix\"><\/div>\n<div>This is done through a \u201cphishing\u201d strategy. Victims will receive seemingly harmless emails with links or attachments. By clicking on the link or downloading the attachment, we can execute the code to download the crypto-mining script onto your computer. The script then runs in the background without the victim\u2019s knowledge.<\/div>\n<div><\/div>\n<div>The other method of cryptojacking is known as \u201cweb mining\u201d. With this method, hackers insert encrypted mining scripts into a website or advertisements placed on various websites. When the victim visits the infected website, or if a malicious advertisement appears in the victim\u2019s browser, the script will be executed automatically. This way, no code needs to be stored on the victim\u2019s computer.<\/div>\n<div><\/div>\n<div>In both cases, the invading code can solve complex mathematical problems, mining crypto-currencies and sending the results to the hacker without the victim\u2019s knowledge.<\/div>\n<h2><span class=\"ez-toc-section\" id=\"zombie_networks_to_mine_cryptocurrencies\"><\/span><strong>Zombie networks to mine cryptocurrencies<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<div>It is true that CPU mining is not very lucrative nowadays, but hackers are much smarter than us so they have already thought about how to solve it.<\/div>\n<div><\/div>\n<div>On the one hand they choose crypto currencies that are easy to mine with CPU, such as Monero, which is also extremely private and anonymous. On the other hand, they don\u2019t limit themselves to infect only one user, but create what are called \u201czombie networks\u201d among several victims in order to increase the computing power.<\/div>\n<div><\/div>\n<div>So while it could take a computer days to mine a single block of Monero, many computers can do it in a tenth of the time. The equation is simple: less time and more profit.<\/div>\n<div class=\"is-divider divider clearfix\"><\/div>\n<div id=\"image_815475990\" class=\"img has-hover x md-x lg-x y md-y lg-y\">\n<div class=\"img-inner dark\"><img fetchpriority=\"high\" decoding=\"async\" class=\"attachment-large size-large lazyloaded\" src=\"https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2020\/09\/Que-es-criptojackiing_2-1024x701.jpg\" sizes=\"(max-width: 1020px) 100vw, 1020px\" srcset=\"https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2020\/09\/Que-es-criptojackiing_2-1024x701.jpg 1024w, https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2020\/09\/Que-es-criptojackiing_2-300x205.jpg 300w, https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2020\/09\/Que-es-criptojackiing_2-768x526.jpg 768w, https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2020\/09\/Que-es-criptojackiing_2-1536x1052.jpg 1536w, https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2020\/09\/Que-es-criptojackiing_2.jpg 1601w\" alt=\"Que es criptojacking Bitnovo\" width=\"1020\" height=\"698\" data-srcset=\"https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2020\/09\/Que-es-criptojackiing_2-1024x701.jpg 1024w, https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2020\/09\/Que-es-criptojackiing_2-300x205.jpg 300w, https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2020\/09\/Que-es-criptojackiing_2-768x526.jpg 768w, https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2020\/09\/Que-es-criptojackiing_2-1536x1052.jpg 1536w, https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2020\/09\/Que-es-criptojackiing_2.jpg 1601w\" data-src=\"https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2020\/09\/Que-es-criptojackiing_2-1024x701.jpg\" data-sizes=\"(max-width: 1020px) 100vw, 1020px\" \/><\/div>\n<\/div>\n<h2><span class=\"ez-toc-section\" id=\"what_is_the_impact_of_cryptojacking_activities\"><\/span><strong>What is the impact of cryptojacking activities?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>If we are victims of this attack, then cryptojacking can have a significant impact on our activities. Among these consequences, we can mention:<\/p>\n<div>\n<p><strong>\u2013 The consumption of our computing resources is increased<\/strong><\/p>\n<\/div>\n<div>Mining activity is a computationally intensive task. Even if this activity can be completed by the CPU, mining will consume a lot of computing power. While today\u2019s CPUs have enough power to perform a large number of tasks simultaneously, when we talk about older devices, we will notice much more excessive consumption and wear and tear will be more obvious.<\/div>\n<div><\/div>\n<div>In addition to the increased use of computing power, power consumption will also increase. The more power the computer uses, the more expensive the electricity bill. To increase computing power, you need energy, more energy generates more heat and more energy consumption is required to handle this situation. All these factors increase the energy consumption of the whole system. In addition, the increase in temperature will shorten the life of the equipment. Indirect costs, which will affect the economy of the user or company under attack.<\/div>\n<div class=\"is-divider divider clearfix\"><\/div>\n<div><strong>\u2013 Our productivity is reduced<\/strong><\/div>\n<div><\/div>\n<div>Like servers, users\u2019 PCs and mobile devices can become victims of cryptojacking when they visit infected or malicious websites. These pages contain javascript code that silently turns the user\u2019s browser into a crypto miner. Result: our machine slows down and becomes hot. This reduces our productivity when using this computer. Now maybe buying bitcoin in Bitnovo is not so fast? Don\u2019t worry, it will still be fast even with cryptojacking.<\/div>\n","protected":false},"excerpt":{"rendered":"<p><span class=\"span-reading-time rt-reading-time\" style=\"display: block;\"><span class=\"rt-label rt-prefix\">Tiempo de lectura:<\/span> <span class=\"rt-time\"> 3<\/span> <span class=\"rt-label rt-postfix\">minutos<\/span><\/span>The sooner you know what cryptojacking is, the sooner you will be prepared to prevent hackers from abusing your resources to mine cryptocurrencies for their own profit.
