What Is Cryptojacking And How To Stop An Attack HP® Tech Takes

What is cryptojacking

Prevent identity risks, detect lateral movement and remediate identity threats in real time. In fact, workplaces are often targeted more because they have numerous high-end devices that can handle the mining process more efficiently. It can also be challenging to find out if there has been a compromise, considering how many factors are there to account for.

Many of these attacks were browser-based ones focused on mining Monero, the most popular coin among cryptojackers. However, ENISA reported that cryptojackers are moving away from browser-based attacks, preferring host-based ones, which, in 2021, accounted for 87% of all cryptojacking attacks. The browser-based approach works by creating content that automatically runs cryptomining software in a user’s web browser when they visit the webpage hosting it. Cryptojackers may create a website with embedded cryptomining JavaScript code and direct traffic to it for the purpose of cryptojacking, or they may compromise an existing site. Cryptojacking might seem like a harmless crime, since the only thing ‘stolen’ is the power of the victim’s computer.

Types of cryptojacking attacks

However, Coinhive’s developers present it as a legitimate way to monetize traffic. In February 2018, cryptojacking code was discovered concealed within the Los Angeles Times’ Homicide Report page. The code on the site was made by a legitimate cryptominer called Coinhive.

Every device overheats over time, especially after heavy or prolonged use. Overheating shortens the lifespan of a device and could lead to irreversible damage. While purchasing a cooling fan may solve regular causes of overheating, cryptojacking malware will only bow to cybersecurity tools.

What Is the Meaning of Cryptojacking?

Victims will either get an email or use a browser or website they are familiar with. An email will show a link that will, upon clicking, infect the device with cryptomining code. In the case of websites or online ads infected by JavaScript code, it’s enough to allow them to load in a browser. 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.

  • They discovered an open server that was running a Kubernetes console, which is used as an administrative portal in cloud application management.
  • That should raise a red flag to investigate further, as could devices over-heating or poor battery performance in mobile devices.
  • Compromised ads can also be placed on a site as pop-unders designed to hide under windows already open on a victim’s computer or phone and avoid detection.
  • When an Ars Technica reporter visited a website that hosted a cryptojacking script, they saw a huge spike in their CPU load.

Monero is particularly common, as it’s designed so people can mine it on average PCs. Monero also has anonymity features, which means it’s difficult to track where the attacker ultimately sends the Monero they mine on their victims’ hardware. Cryptojackers lure victims into clicking on harmless-looking links that install cryptomining software onto a victims’ device. For instance, Google Android phones are susceptible to Trojan horse cryptojack attacks through apps on Google Play Store. Cryptojackers target victims’ computing resources to offload the mining expenses to as many entities as possible. Though cryptojacking is designed to be undetectable, over time, its high processing demands can damage victims’ devices and cause poor device performance, high electricity bills and shorter device life spans.

How to Detect and Prevent Cryptojacking

Typically, an army of miners toils away on the puzzle simultaneously in a race to be the first with the puzzle proof that authenticates the transaction. “Comprehensive online protection software can protect you in several ways,” McAfee said. “Unlike Google Play and Apple’s App Store, which have measures in place to https://www.tokenexus.com/ review and vet apps to help ensure that they are safe and secure, third-party sites might very well not,” cybersecurity company McAfee noted. Phishing is a scam where attackers deceive people into revealing sensitive information. Cybercriminals usually gain access to a person’s device or server through malware.

  • The apps supposedly came from three different developers, although Symantec suspects that the same individual or organization was behind them all.
  • As it has evolved into a multi-vector attack that spans across endpoint, server, and cloud resources, preventing cryptojacking takes an orchestrated and well-rounded defense strategy.
  • Connect with us at events to learn how to protect your people and data from ever-evolving threats.
  • Cryptocurrencies are encrypted digital currencies that can be used as online payment in exchange for goods and services.
  • Instead, cybercriminals leverage their access to accomplish multiple goals, such as combining cryptojacking and data theft.
  • When combined with other red flags such as overheating or a large electricity bill, you may want to run antivirus software to find and remove the cryptojacking malware.

Mining just one bitcoin costs, on average, $35,000, according to Visual Capitalist calculations. One bitcoin requires nearly 1,400 kilowatt hours, equivalent to the average amount of energy consumed by an American family in 50 days, according to Digiconomist. As a result, the cost of mining a single bitcoin can be higher than the price of that one What is cryptojacking bitcoin. One obvious option is to block JavaScript in the browser that you use to surf the web. Although that interrupts the drive-by cryptojacking, this could likewise block you from using functions that you like and need. There are also specialized programs, such as “No Coin” and “MinerBlock,” which block mining activities in popular browsers.
