Each transaction is linked to the previous and subsequent transaction, creating a chain of time-stamped records. Installing the most recent updates for your software, operating system, and apps is also recommended, particularly for online browsers. Furthermore, JavaScript should be disabled when accessing the internet to prevent your machine from becoming infected with cryptojacking software. Additionally, numerous mining pools offer several plug-and-play mining solutions, which attackers can modify for cryptojacking.
According to security researcher Troy Mursch, both the legitimate, non-consensual and criminal uses of Coinhive led to the company holding 62 percent of the browser-based cryptojacking market share, as of August 2018. One of the main differences between Coinhive and its predecessors is that it mines a privacy-centric coin called Monero rather than Bitcoin. With the launch of Coinhive and the high price of Monero, we saw a huge spike in browser-based cryptojacking in late 2017.
How do you detect cryptojacking?
On the other hand, miners can earn crypto as a reward through the cryptocurrency mining process by solving a mathematical problem. Attackers inserted Coinhive script into the software, allowing them to mine monero using visitors’ browsers. 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.
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. 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. “Many of the cryptomining samples from Linux-based systems have some relationship to the XMRig application,” explained the report, which showed that 89% of cryptomining attacks used XMRig-related libraries.
Cloud Cryptojacking
These devices would then be used to mine cryptocurrencies with a range of different scripts. This all started to change toward the end of 2017, when the cryptocurrency market was reaching its peak. Much like Bitcoin Plus and Tidbit, it made it simple for websites to mine cryptocurrencies through their site visitors’ browsers. Cryptojacking has its roots in 2011 when Bitcoin was still in its infancy and mainly used by cypherpunks and on illicit online marketplaces.
The following steps can help prevent cryptojacking from running rampant on enterprise resources. When a crook can mine for cryptocurrency on a seemingly limitless pool of free compute resources from victim machines, the upside for them is huge. Another method is to inject a script on a website or an ad that is delivered to multiple websites. Once victims visit the website or the infected ad pops up in their browsers, the script automatically executes.
How to protect yourself from cryptojacking attacks
Cybercriminals held a sizable portion of the overall Monero (XMR) hash rate when Coinhive was in operation. However, Monero’s owners shut down Coinhive in March 2019 due to the rapid decline in the price of XMR and the company’s declining profitability.

Advanced Bot Protection – Prevent business logic attacks from all access points – websites, mobile apps, and APIs.
The previous cryptojacking methods we covered dealt with functional hardware from the targeted devices and are relatively easy to pull off. Cryptocurrencies are created through a process called mining, where computers solve complex mathematical problems to release new coins. But while mining can be a lucrative endeavor, it can also be quite dangerous. All cryptocurrencies are decentralized monetary units that can be transferred freely between participants in a network. In other words, cryptocurrency exists as units of electricity that are converted into code and have a monetary value. To maximize their capacity to spread across a network, cryptomining code could include multiple versions that leverage weaknesses in different network protocols.
Cryptojacking – What is it?
A malicious crypto mining code is inserted into the unsuspecting victims’ devices through a malicious link sent in a phishing email. While Bitcoin is the most widely known cryptocurrency, cryptojacking attacks usually involve mining other cryptocurrencies. What is cryptojacking 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.
- The consequences of a cryptojacking attack may be limited to decreased performance, but don’t get too complacent.
- Quantity limits may apply to orders, including orders for discounted and promotional items.
- It is also good practice to install the latest software updates and patches for your operating system and all applications — especially those concerning web browsers.
- To give you an idea of just how power-hungry mining can be, in 2019 Bitcoin mining was using about as much electricity as the entire country of Switzerland.
