What does Cryptojacking mean?

A covert kind of cybercrime that has become more popular in recent years is called cryptojacking. It entails the illicit mining of cryptocurrency using a device's processing power, frequently without the owner's knowledge or agreement. To achieve this, hackers infiltrate devices with malware that launches cryptocurrency mining scripts in the background, stealthily consuming the device's processing power to solve intricate mathematical puzzles necessary for cryptocurrency mining.

Phishing emails, hacked websites, and rogue mobile applications are just a few ways that the harmful code might get onto devices. Following infection, the crypto mining script operates covertly on the compromised device, using system resources and earning money for the hacker while the target is kept unaware of the continuous abuse. Slow device performance, higher electricity costs, and even hardware damage from overstress are just a few of the ways that cryptojacking can have negative effects.

From the standpoint of the hacker, cryptojacking's simplicity and scalability are its greatest features. Cryptojackers can quickly get huge computational power and make large sums of money by infecting a large number of devices. The victims, on the other hand, are frequently unaware of the ongoing exploitation and only become aware of compromise when their gadgets begin to malfunction or overheat as a result of the increased load on system resources.

Impact Of Cryptojacking

Although some people may believe that cryptojacking is a victimless crime, the devices that are infected by it can suffer greatly as a result of it. The effects of a device being infected with cryptojacking malware can be extensive and can go unreported until it's too late.

An obvious decrease in device performance is one of the most evident consequences of cryptojacking. The device's resources are taxed as the malicious code operates in the background, using up precious processing power to mine cryptocurrency. Slow reaction times, frequent crashes or freezes, and an unpleasant user experience might result from this. Because of the enormous pressure on its components, the gadget may in certain situations even overheat, which could result in long-term damage.

However, the issues don't end there. The owner of the gadget may also see an increase in electricity costs as a result of cryptojacking. Because mining requires a lot of energy, the extra power usage can mount up quickly—especially if the malware has been operating covertly for a while. The financial impact can be substantial in certain instances; victims have reported unanticipated energy bills totaling hundreds or even thousands of dollars. Not to mention the possible security hazards related to cryptojacking, since if the malware is allowed to spread, it may pave the way for more attacks or data breaches.

Examples Of Cryptojacking

1. The Coinhive Miner

In September 2017, the first occurrence of cryptojacking was reported. A code that enabled miners to use third-party CPUs to mine the cryptocurrency Monero was released by Coinhive, a cryptocurrency mining service, during this event. At the time, Coinhive was thought to be the sixth most widespread malware in the world.

However, the falling value of cryptocurrencies, especially Monero, forced the closure of this business in 2019. The service was officially shut down in 2019, yet evidence of its cryptojacking still exists. Criminal IP Asset Search estimates that as of 2023, at least 5,000 devices are still compromised by Coinhive cryptojacking.

2. Qubitstrike

Users of Jupyter Notebooks are the target of this crypto mining trojan. Qubitstrike uses Discord's bot functionality to send orders on compromised nodes and monitor the attack's progress while covertly mining the cryptocurrency XMR.

3. Applications Affected by Cryptojacking in the Microsoft Store

It was found that eight Microsoft Store applications were infected with cryptojacking JavaScript in 2019. Fast-search Lite, Clean Master+ (Tutorials), VPN Browsers+, Downloader for YouTube Videos, FastTube, Findoo Browser 2019, and Findoo Mobile & Desktop Search were those applications. Following this discovery, Microsoft deleted the compromised apps right away.

4. AMPERSQUID

Amazon Web Services (AWS) products including AWS Amplify, AWS Fargate, and Amazon SageMaker are the main targets of this cryptojacking attack. It has been revealed that AMBERSQUID can penetrate cloud services without triggering requests for more resources from AWS.

How to Spot Cryptojacking Signs

Even while the malicious code could work covertly in the background, there are a few obvious indicators that can let you know whether your device has cryptojacking malware on it.

An abrupt and inexplicable surge in CPU utilization is one of the most noticeable signs. It may indicate that your gadget is being used without your knowledge to mine cryptocurrencies if you see the processor on it operating at a high level for no apparent reason.

A dramatic decrease in the device's performance, with apps taking longer to launch and general response becoming sluggish, is another cause for concern. Because of the tremendous pressure on its components, the device can potentially overheat in certain instances.
