What Is Cryptojacking Types, Detection & Prevention Tips

What is cryptojacking

A single hijacked device won’t make an attacker a whole lot of cash, but if they target thousands or millions of computers, tablets, smartphones and IoT devices, it can be a lucrative moneymaker. Once your computer is infected and an attacker successfully has remote command of your device, you may notice it running slower than usual, or hear the fan running more often than normal. That is because mining is a resource-intensive activity, and can affect your ability to use your computer or phone to its full capabilities. That’s right — you do not have to buy, sell, trade, or hold cryptocurrency to be a target of a cryptojacking cybercrime. Government websites and more than 4,000 others worldwide were exploited by cryptojacking viruses. Some hackers directly break into wallets and steal money, others promise love to cheat you out of your coins, and some are so sneaky you rarely even notice your device has been compromised.

Use a good cybersecurity program:

Hackers only need a few lines of JavaScript code to sneak into a device that later will run the mining malware surreptitiously in the background. He warns, though, that cryptominer authors can write their malware to avoid that detection method. Cryptojacking can also happen through a supply chain attack, where cryptomining code compromises JavaScript libraries. Many of the protocols on the Ethereum network have their own token or cryptocurrency. In most cases, users can use the cryptocurrency they have to vote on how a certain platform will operate in the future.

Protecting Against Cryptojacking

If your computer network has been attacked by cryptojacking, it’s time to take a closer look at the strength of your security. Varonis has anti-ransomware software and services your organization needs to stay alert and protected against malicious cryptomining. Malware created for cryptomining uses up system resources much the same as cryptojacking scripts.

  • If your computer is suddenly running slowly or kicking on the fan a lot more than usual, monitor your CPU usage via the operating system tools to try and identify malicious processes that could signal cryptojacking.
  • This is done without website owners’ knowledge, and they have little control over whether their site runs the software.
  • They discovered an open server that was running a Kubernetes console, which is used as an administrative portal in cloud application management.
  • If you have inadvertently downloaded cryptojacking malware, it’s important to get it off your computer or device so that it can return to its normal state.
  • RedLock came across the scheme during one of its scans for insecure and misconfigured cloud servers.
  • Not only did this lead to a large number of websites using it secretly, but cyber criminals also integrated Coinhive into their attacks.

In the past, cryptojacking was primarily an endpoint malware play, existing as yet another moneymaking objective for dropping malware on desktops and laptops. Traditional cryptojacking malware is delivered via typical routes like fileless malware, phishing schemes, and embedded malicious scripts on websites and in web apps. When hackers use cloud cryptojacking, they search through an organization’s files and code for API keys to access their cloud services. Once access is gained, hackers siphon unlimited CPU resources for cryptomining, resulting in a huge increase in account costs. Using this method, hackers can significantly accelerate their efforts of cryptojacking to illicitly mine for currency. The core idea behind cryptojacking is that hackers use business and personal computer and device resources to do their mining work for them.

The cumulative losses from cryptojacking have amounted to billions of dollars, underscoring the severe economic consequences of this form of cybercrime. As cryptojacking techniques evolve, the financial stakes continue to rise, making it essential for stakeholders to stay vigilant and implement robust cybersecurity measures. To forecast the future landscape of cryptojacking, I gathered data from ( Symantec) that reports a 163% increase in browser-based cryptojacking activity. By the end of 2024, approximately 13,477,050 users are predicted to be affected as the number of scammers using mining software for cryptojacking significantly increases. The problem for the computer’s owner is that this takes up processor power, making other operations take much longer.

Whichever method is used, the script runs complex mathematical problems on the victims’ devices and sends the results to a server which the hacker controls. The software works in the background, https://www.tokenexus.com/ mining for cryptocurrencies or stealing from cryptocurrency wallets. The unsuspecting victims use their devices typically, though they may notice slower performance or lags.
