What Is Cryptojacking and How to Avoid This Coin-Mining Malware

What is cryptojacking

A cryptojacking attack may also be referred to as malicious cryptomining, as hackers gain access to devices through rogue apps and browser downloads. Virtually all kinds of devices can be compromised, from desktop PCs and laptops to smartphones and even network servers. Slow performance hurts business productivity, system crashes and downtime cost sales and reputation, and expensive high-performance servers become expensive poorly-performing servers. And of course, operational costs spike as corporate resources are directed away from their intended uses to serve the needs of cryptominers. There’s also cryptojacking malware, which works just like any other malware.

But cryptojacking is a peculiar case as many people fall victim without even realizing it. The more computing power your devices possess, the more potential harm there is, especially in a work environment. Although cryptojacking may seem harmless as hackers are not taking your money, these attacks can damage your device and run up an enormous electricity cost.

Cryptomining Begins

Cybercriminals are looking for websites where they can embed cryptomining code. Regularly monitor your own websites for changes to webpages or any files on the web server. This early detection can prevent your systems from being compromised by cryptojacking.

  • Here are some of the methods you can use to detect cryptojacking before it’s too late.
  • A cryptojacking attack may also be referred to as malicious cryptomining, as hackers gain access to devices through rogue apps and browser downloads.
  • This meant that Coinhive would receive 100 percent instead, essentially tripling its profits.
  • It continuously solves cryptographic puzzles or algorithms to validate and confirm transactions on the cryptocurrency network.
  • We recommend running security software that automatically blocks cryptocurrency miners in your browser.

Look for any unfamiliar processes that are using a large amount of CPU power and perform a web search to see if they’re legitimate. Of course, sometimes background operating system processes use a lot of CPU power as well—especially on Windows. CoinHive was the first mining script to achieve public attention, especially when it was integrated onto The Pirate Bay. However, there are more mining scripts than CoinHive, and they’ve been integrated into more and more websites.

If they get too greedy, it makes the user’s experience noticeably slower and can have other negative impacts. While much of this article has taken a negative tone toward cryptojacking, the technique itself isn’t inherently bad. If websites ask for explicit consent before conducting it at the browser level – or give their users the opportunity to choose between it and ad displays – the process doesn’t have to be wholly negative. While you’re at it, search for any other changes the attackers may have made and reverse any that you find. This includes the basics like changing your passwords, updating all of your software and setting up two-factor authentication.

If you don’t notice your PC is running slowly or a process is using 100% CPU, you won’t even notice the malware. In a cryptomining scenario, the reward is clandestine access to the processing power in a user’s device. What is cryptojacking 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.

The Start of Cryptojacking

In 2022, ABC 7 revealed that Chicago’s Champaign County was hit with a DDoS attack that temporarily slowed the ballot counting process. This could be as straightforward as hacking into a database to obtain someone’s social security number or personal address, or it could only involve research in order to find compromising Twitter posts. Anything and everything can be weaponized in the hands of a cybercriminal, but things really ramp up when they’re working for a government’s payroll. CNN reports that another devastating cyber attack occurred in 2021 when Colonial Pipelines was held hostage by ransomware. Colonial Pipelines had to shut down to contain the damage, and since around half of all gasoline used on the East Coast originates from this company, the malware hobbled the whole region. While this attack wasn’t an example of cyber warfare — the apolitical group DarkSide was responsible — it demonstrated how ransomware could shut down an entire country or region.

Although these scams may appear to be legitimate, interacting with them can unleash a Trojan onto your computer network and allow cybercriminals to steal your computing power. Cryptojacking is a form of malicious cryptomining that allows cybercriminals to mine cryptocurrency using another entity’s computing power. However, an all-around cybersecurity program is a more comprehensive solution. It can serve as a catch-all because it detects threats across the board and can provide protection even if hackers find workarounds for the software designed to block mining. However, most people’s passwords are fairly short sequences of letters and digits. During the mining process, a computer’s resources are devoted to figuring out the encryption.

Cryptocurrencies are encrypted digital currencies that can be used as online payment in exchange for goods and services. These cryptocurrencies are created by combining computer programs and computer processing power in what is known as blockchain technology. Browser-based cryptojacking is a type of attack that involves web browsers like Firefox, Safari, and Chrome. These scripts are embedded https://www.tokenexus.com/ into corrupted versions of the browsers, and the device’s resources are utilized when the browsers are launched. When cryptojacking malware overwhelms a system, it can result in severe performance issues, which will have an immediate impact on your customers and end-users. If, for instance, a healthcare provider is the victim, staff could be unable to access critical patient health data.

  • The Ethereum network also incorporates solving mathematical problems, but it takes less computing power to do so.
  • Unlike traditional currencies, cryptocurrencies like bitcoin aren’t backed by a specific government or bank.
  • Special computers collect data from the latest Bitcoin or other cryptocurrency transactions about every 10 minutes and turn them into a mathematical puzzle.
  • The stealthy mining operations hog system resources, slowing operations, and potentially shortening the device’s lifespan due to wear and tear from overheating components.
  • By the end of 2018, Outlaw had already achieved significant success, with more than 180,000 compromised hosts, including Windows servers, websites, IoT systems and Android devices.
  • If an attacker can take advantage of a security hole or trick you into installing their malware, they can run a mining script as a background process on your computer—whether it’s a Windows PC, Mac, or Linux system.
