Cryptojacking What is it, and how does it work?

Evolving tools like cloud monitoring and container runtime security scanning can offer additional visibility into cloud environments that may be impacted by unauthorized cryptominers. Cloud providers are baking in this kind of visibility into their service, sometimes as add-ons. Sometimes the first indication on user endpoints is a spike in help desk complaints about slow computer performance. That should raise a red flag to investigate further, as could devices over-heating or poor battery performance in mobile devices.

Additionally, the cryptocurrency ecosystem is designed in a way that makes mining harder and reduces the rewards for it over time and with more mining competition. This makes legitimate cryptocurrency coin mining an extremely costly affair, with expenses rising all the time. The primary impact of cryptojacking is performance-related, though it can also increase costs for the individuals and businesses affected because coin mining uses high levels of electricity and computing power. 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.

Romanian attackers target Linux machines with cryptomining malware

Software composition analysis (SCA) tools provide better visibility into what components are being used within software to prevent supply chain attacks that leverage coin mining scripts. TeamTNT was one of the first https://www.tokenexus.com/ hacking groups to shift cryptojacking focus heavily to cloud-oriented services. A study last fall by Google’s Cybersecurity Action Team reported that 86% of compromised cloud instances are used for cryptomining.

Cryptojacking harnesses victims’ machines to mine, or perform the computations necessary to update cryptocurrencies’ blockchains, thereby creating new tokens and generating fees in the process. These new tokens and fees are deposited to wallets owned by the attacker, while the costs of mining—including electricity and wear and tear to computers—are borne by the victim. RedLock couldn’t say just how many bitcoins the operation may have mined, but there was the potential for it to be substantial. Large organizations like Tesla already use significant amounts of electricity and processing power, so a hefty cryptojacking scheme may be able to continue without any noticeable usage spikes, keeping it undetected. The Kubernetes console turned out to be mining cryptocurrency, and as the researchers dug deeper, they discovered that it was Tesla’s.

When he’s not watching Rick and Morty or his favorite sports teams, Calvin is writing about startups, blockchain, cybersecurity, and other realms of technology. Armed with more of an understanding of cryptojacking, you should be sure to remain vigilant and when possible, take a closer look at the strength of your security. With so many processes going on in a computer, it can be easy to overlook the risks of cryptojacking. A Monero-mining cryptojacking botnet was even discovered on a United States Department of Defense web server in early 2020.

A cryptojacking blocker is a web extension designed to prevent your computer from being used to mine crypto while you visit websites. Cryptojacking works by either using malware or doing what is referred to as drive-by cryptomining. When a hacker uses malware, a portion of your computer is taken over and controlled, similar to what happens What is cryptojacking with ransomware. But unlike ransomware, the control happens unseen, in the background, while you continue to use the device. In the bitcoin blockchain, it takes a relatively long time for a hash to get solved, making it inefficient for many purposes. This inefficiency drove the need for a different kind of blockchain, the Ethereum network.

It appears that the attackers had come across this Kubernetes console, and realized that there was a huge security lapse – it hadn’t been password protected. While the amount of resources drawn will vary, cryptojacking malware or browser-based cryptojacking can cause other websites to load slowly and make many processes lag. When an Ars Technica reporter visited a website that hosted a cryptojacking script, they saw a huge spike in their CPU load. When they closed the site, it dropped back down from a whopping 95 percent to just nine percent. If someone is willing to cryptojack, it gives them a way to mine cryptocurrencies without having to use their own computational resources or pay for the machines.
