What is cryptojacking

The cryptojacking code works in the background of systems without you noticing. Your hardware’s processing power is used to mine cryptocurrency which makes your hardware much slower than usual. You’ll also have someone on your computer without your knowledge which is always dangerous when it What is cryptojacking comes to your personal data. 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.

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. The script checked for other miners on the system, and if it discovered any, it stopped them from running, then ran its own binaries. Not only could it mine a larger amount of currency if it wasn’t sharing a system’s resources with one or more other cryptominers, but Outlaw’s process allowed it to take over mining activities from other botnets.

Introduction to Cryptojacking

This activity requires a significant amount of electricity – for example, the Bitcoin network currently uses more than 73TWh of energy per year. It moves through your network, infecting one device after another, enslaving them all, and consuming https://www.tokenexus.com/ their resources in the process. Another major cryptojacking incident was the Siacoin Internet Cafe hack when hackers across China mined around $800,000 million in Siacoin by infecting internet cafes with malicious cryptojacking code.

  • When detected, cryptojacking is very difficult to trace back to the hacker.
  • Secure your on-premises or cloud-based assets – whether you’re hosted in AWS, Microsoft Azure, or Google Public Cloud.
  • In the same year, Google’s Cybersecurity Action Team found that 86% of its observed compromised cloud platforms resulted from cryptojacking.
  • The attack methods are limited only by the cryptojackers’ creativity, but the following are some of the most common ones used today.

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. If they manage to take over enough devices, they can have a large amount of processing power at their disposal.

Also, there are many cryptocurrencies that can be mined without a dedicated graphics card or specific hardware. The reason miners choose to mine cryptocurrencies is that they want to earn money in the form of cryptocurrency. First, by checking all transactions, cryptominers make sure that people don’t abuse the system by spending the same cryptocurrency twice. Second, because miners receive payment in Bitcoin, they’re introduced new cryptocurrency to the network which makes it grow.

This can involve alterations to help slip it past the latest detection and prevention methods, such as antivirus programs or ad blockers. Cybercriminals are targeting the software supply chain by seeding open-source code repositories with malicious packages and libraries that contain cryptojacking scripts embedded within their code. With developers downloading these packages by the millions around the globe, these attacks can rapidly scale up cryptojacking infrastructure for the bad guys in two ways. The malicious packages can be used to target developer systems—and the networks and cloud resources they connect to—to use them directly as illicit cryptomining resources. Or they can leverage these attacks to poison the software that these developers are building with components that execute cryptomining scripts on the machines of an application’s end user.

The negative effects of cryptojacking

As the attacker siphons off processing power for mining, the victim’s computer becomes sluggish, leading to slower load times, unresponsive applications, and an overall frustrating user experience. Reduced productivity can be particularly detrimental in a business environment, impacting operations and employee efficiency. Cryptojacking carries lower risks for cybercriminals compared to some other types of attacks. For example, launching a ransomware attack might lead to negotiations with the victim and the risk of detection during the payment process.

In some cases, the cryptojacking software is binary-based and the targets need to download and execute it before it will start mining. This means that simply visiting certain sites can potentially lead to cryptojacking. Cryptojacking has become an increasingly popular way for fraudsters and criminals to extract money from their targets in the form of cryptocurrency. One widely publicized hack, the WannaCry worm hack, affected systems on several continents in May 2017. In this instance of cryptojacking, fraudsters encrypted victims’ files and demanded cryptocurrency ransoms in the form of Bitcoin in order to decrypt them.

What if your website has been compromised with cryptojacking code?

You can also blacklist sites known for cryptojacking, but this may still leave your device or network exposed to new cryptojacking pages. Cryptocurrency mining involves either solving hashes to generate blocks that get added to the blockchain or verifying transactions happening between the blockchain’s users. The “mining” process is performed by a computer that is essentially coming up with a password to crack an encryption. If a computer were charged with figuring out the password to your laptop, for instance, it would have to try enough combinations of numbers or letters until it got it right. 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.
