All You Should Know About Cryptojacking

What is cryptojacking

Increased processor usage can lead to the device overheating and may even damage it. Businesses may need to devote costly IT resources to find the cause of multiple computers suddenly facing performance issues. Not to mention the suddenly spiking electricity bills that come from the computers working overtime. For basic endpoint users, install browser extensions designed to block cryptomining, use privacy-focused ad-blockers, and block known cyberjacking websites. The malware does not aim to steal data or blackmail the user, but instead remains in the background as long as possible, in order to carry out mining stealthily.

What is coin Miner malware?

Coinminer is an unwanted malicious software which uses the victim’s computational power (CPU and RAM mostly) to mine for coins (for example Monero or Zcash). The malware achieves persistence by adding one of the opensource miners on startup without the victim’s consensus.

Similar to the Los Angeles Times hack, the miner was generating Monero. For bitcoin mining, the computer needs to be very powerful to compete with the other devices trying to solve problems on the blockchain. For some currencies, however, solving the problems requires less power, and a normal smartphone, tablet, desktop, laptop, or server may be fast enough to get the job done. If a hacker can cryptojack devices on your network, they can therefore get you to fund and facilitate their cryptocurrency mining. However, most people’s passwords are fairly short sequences of letters and digits.


For individual users, slower computer performance might be just an annoyance. Cryptojacking is an unauthorized use of someone’s device to mine digital currency. By using a huge network of computers, hackers can mine crypto while using their victims’ electricity, devices and computing power to increase their profits. Unfortunately, in most cases, when you fall victim to cryptojacking it will go unnoticed.

  • Cryptojacking works by either using malware or doing what is referred to as drive-by cryptomining.
  • Cryptojacking seems like a victimless crime, as no damage is done to a victim’s computer and no data is stolen.
  • Checkout Cryptomindedfor a curated collection of some of the best cryptocurrency resources.
  • One of the main reasons behind this is how inexpensive it is to carry it out, combined with the fact that the returns in comparison are often rather high.

The consequences of a cryptojacking attack may be limited to decreased performance, but don’t get too complacent. Cybercriminals looking to find a way to maintain a steady profit are turning into cryptojacking. In the event that a device or network is compromised by a web-based cryptojacking attack, a number of steps can be taken to stop the cryptomining. Following are several techniques used for cryptojacking protection. Used in combination, these techniques help prevent cryptojacking attackers from successfully setting up a cryptomining operation.

When done legitimately, the website should inform its visitors about this type of operation. This infection is more profitable than mining through a website, but it’s also harder to deliver.

Who Is Most At Risk From Cryptojacking Attacks?

On the other hand, this can also mean that the users would have to verify a thousand cryptocurrency transactions. When a block is verified by someone it’s added to the digital blockchain. Malicious software infects a device after a malicious link on a website or in an email is clicked. Once the infection has taken hold of a computer, the unauthorized mining of cryptocurrency begins without the awareness of the user. Some other steps one can take include keeping one’s web filtering tools up to date. That way, if one notices that a web page has cryptojacking scripts, one can alert other users in the organization against accessing it. Not surprisingly then, prevention is way better than cure and one can prevent cryptojacking by installing security software.

Because multiple cryptominers can work on a transaction, but only one will receive the reward, there is motivation to find maximum processing power, in order to cryptomine faster. Cryptojacking is a combination of a malware attack and exploitation of co-opted computer resources. Malware is used to gain access to computers or mobile devices for use in cryptomining for cryptocurrency. The same report said Monero was the cryptocurrency of choice for 2019 cryptojacking activities because of its focus on privacy and anonymity.

Master of Science in Cyber Security degrees with industry certifications embedded into their programs. Of this series, so you can learn how to tell if you’ve been cryptojacked. Or, if you’re an unscrupulous hacker, you could hijack thousands of computers to do the work for you. With EdTech—technology that makes education more engaging—the education landscape is changing, and so is the demand. In 2020, the global education technology market was valued at US$89.49 billion. After all, it dictates how your business offering reaches and convinces your target audience. According to a study by the Harvard Business Review, companies with a defined sales process earned 18% more revenue than companies with none.

Even with this in mind, there are some security steps you can take to ensure your chances of being cryptojacked are as small as possible. However, there are a few things that may help you prevent or detect cryptojacking malware. Sometimes, even closing a browser is not sufficient to prevent the script from running. Often, hackers use a simple trick to create a hidden pop-up window that fits under the taskbar. Moreover, once detected, it is hard to trace the malware to the source, and hackers prefer mining cryptocurrencies like Monero and Zcash. These are harder to trace compared to more popular ones like Bitcoin.

How long does it take to mine 1 Bitcoin on a laptop?

In general, it takes about 10 minutes to mine one bitcoin. However, this assumes an ideal hardware and software setup which few users can afford.

Hackers prefer cryptojacking over ransomware because it guarantees a steady flow of money. Because you are rewarded with a bitcoin once the block is added to the blockchain. So yes, your computer could essentially be making you money without you lifting a finger. In both cases, once a browser or device is infected, the code uses up the CPU’s power to perform complex calculations.

How Can I Avoid Cryptojacking?

Cryptocurrencies are digital funds stored on electronic wallets (also known as “virtual wallets”) that are encrypted and exist on electronic communication devices. Coins are cryptocurrency units which are entered into a database for recording the transactions. The digital transaction takes place online between the virtual wallet owners and recorded on a public ledger. Then, special computers transform the digital transaction into a complicated mathematical puzzle, and thereafter miners independently solve and confirm the digital transaction. The reward for solving the mathematical puzzle is to receive a new cryptocoin.

Many of the users are unfamiliar that their AWS account is minting cryptos for bad guys until their credit cards are maxed, and further payments are declined,” Smith added. If you don’t perform any intensive tasks on your system, but it still heats up too quickly, chances are malware is running in the background.

Advance Threat Protection

If you are using a Windows computer , you should take a look at your list of current processes. The tabs at the top will allow you to look at different types of data, so take a quick look. The performance monitor (under the “performance” tab)will give you a good idea of the resources being used by your computer. The first sign that you will see is a reduction in your computer’s speed. Loading times will go up quite a bit, as a lot of your computer’s resources are being utilized by the hacker.

  • Cryptojacking essentially gives the attacker free money—at the expense of your device and the overall health of your network.
  • In order to unlock a coin, one must successfully mine with a high powered computer or a group of computers.
  • Browser cryptojacking is a little easier to resolve because all you need to do is close the window.
  • About how you can protect all your business technology from cryptojacking and other malicious attacks.

E-mail phishing is the classic form, but modern hackers have branched out and learned how to phish with video calls and other forms of communication as well. To get around these barriers of cost, some people resort to shady and illegal methods. Then, they can basically “leech” off your bandwidth and put it to work mining a cryptocurrency of their choice. If you think there’s a cryptomining code on your computer you should run an antivirus program to scan your drives for any threat. If any files are found in the scan that you don’t recognize you need to delete them as soon as possible. Cryptomining scripts are usually hidden in ads on websites so if you use an ad-blocker you can avoid some forms of cryptojacking. Some ad-blockers, such as Adblock Plus, even have a feature in which they can identify some cryptomining scripts.

Main Types Of Cryptojacking

Hackers embed their cryptojacking scripts into hundreds of websites. When a user visits those websites, the script downloads and executes. Hackers also inject their malware into pop-up ads that appear on many websites. However, cryptojacking hasn’t gone away entirely, not by a long shot — it actually saw an increase in the first quarter of 2021. However, by taking the proper precautions and keeping an eye on any unusual performance of your digital device, you should be able to avoid becoming a victim.

Likewise, finding the origin of the high CPU usage can be difficult. Processes might be hiding themselves or masking as something legitimate in order to hinder you from stopping the abuse. As a bonus to the cryptojackers, when your computer is running at maximum capacity, it will run ultra slow, and therefore be harder to troubleshoot.

Bitcoin’s success inspired dozens of other cryptocurrencies that operate in more or less the same way. Less than a decade after its invention, people all over the world use cryptocurrencies to buy things, sell things, and make investments. In February 2018, a Spanish cybersecurity firm, Panda Security, announced that a cryptojacking script, known by its nickname “WannaMine,” had spread to computers around the world. The new malware variant was being used to mine the cryptocurrency monero. Cryptojackers are a clever lot, and they’ve devised a number of schemes to get other peoples’ computers to mine cryptocurrency. Most are not new; cryptomining delivery methods are often derived from those used for other types of malware such as ransomware or adware.

Cryptocurrencies created a new decentralized system that many hoped would make it difficult to forge transactions. However, hackers have still found a way to abuse it and make easy money. With a technique known as Cryptojacking, criminals can use your device to gather cryptocurrencies without you knowing. But, with the recent surge in crypto’s popularity, cryptojacking has made a comeback. As per Kaspersky’s report, 200,045 users encountered miners on their devices in March, compared to 187,746 in January. In the first quarter of 2021, a total of 432,171 unique users encountered miners. Protect Web browsers on endpoints with specific add-ons to protect against crypto-currency mining by blocking malicious scripts.

What is cryptojacking

Furthermore, Bitcoin mining uses more resources than Monero mining, so your device will overheat more often, and the power consumption will go through the roof. We’ve covered myriad types of malware and cyber attacks on the blog over the years, and few are as insidious as cryptojacking.

Detecting a cryptojacking malware that has already infected your system is pretty tricky. This malware can pass through security encryption and software undetected. There are several signs you need to look out for when it comes to cryptojacking. The first and most important is a decrease in your computer’s performance. Cryptomining takes up too much computing power in the background leaving fewer resources for your daily activity. Install an antivirus app that blocks web threats and malicious ads – which are a common source of embedded cryptojacking scripts.
