Drive-by mining, also known as browser cryptojacking, is a method used by malicious actors to clandestinely mine cryptocurrencies on unsuspecting users’ computers through web browsers. This form of mining exploits the computational resources of visitors to websites without their consent or knowledge. While cryptocurrency mining itself is a legitimate process used to validate transactions and secure blockchain networks, Drive-by mining misuses these principles for malicious purposes.
The history of the origin of Drive-by mining and the first mention of it
Drive-by mining emerged in the early 2010s when cryptocurrencies like Bitcoin started gaining significant popularity. Cybercriminals recognized an opportunity to mine cryptocurrencies without investing in expensive hardware and electricity costs by leveraging the processing power of other people’s computers. The first mention of Drive-by mining can be traced back to 2011 when a well-known security researcher, Mikko Hyppönen, reported finding Bitcoin mining scripts embedded in a malicious advertisement on a website.
Detailed information about Drive-by mining: Expanding the topic Drive-by mining
Drive-by mining operates through a combination of malicious scripts and vulnerabilities in web browsers and plugins. The process usually begins when a user visits a compromised website that hosts the mining script. The script, often written in JavaScript, automatically executes in the visitor’s browser without their knowledge or consent. It then harnesses the user’s CPU power to mine cryptocurrencies, typically Monero due to its privacy features, as it offers greater anonymity compared to Bitcoin.
The mining script runs in the background while the user interacts with the website’s content, remaining unnoticed in most cases. As the user’s CPU is exploited for mining, it can cause increased processor usage, leading to decreased device performance, overheating, and decreased battery life on mobile devices.
The internal structure of the Drive-by mining: How Drive-by mining works
The internal structure of Drive-by mining involves several key components:
-
Malicious Scripts: Drive-by mining utilizes JavaScript or other scripting languages to embed mining code into web pages. This code connects to a mining pool, where the combined computational power of multiple infected machines mines cryptocurrencies.
-
Compromised Websites: Cybercriminals often exploit security vulnerabilities in websites or inject malicious scripts into legitimate websites. Visitors to these compromised sites unknowingly run the mining code when they access the page.
-
Mining Pools: The mining scripts connect to mining pools, which are servers that coordinate the collective mining efforts of multiple machines. Rewards are distributed among participants based on their contributed computing power.
Analysis of the key features of Drive-by mining
Drive-by mining possesses several noteworthy features, making it an attractive option for malicious actors:
-
Stealthy Nature: Drive-by mining operates in the background, making it difficult for users to detect its presence.
-
Low Entry Barrier: Cybercriminals do not need specialized knowledge or hardware, as they leverage the resources of unwitting users.
-
Monetization Strategy: Illicitly mined cryptocurrencies can be converted into fiat money, providing an incentive for attackers.
Types of Drive-by mining
Drive-by mining can be categorized based on its execution methods:
| Type | Description |
|---|---|
| Browser-Based Mining | Malicious scripts embedded in websites exploit visitors’ browsers for mining. |
| Malvertising Mining | Malware-laden advertisements deliver mining scripts to users when they load compromised ads. |
| Plugin/Extension-Based | Malicious browser plugins/extensions automatically execute mining scripts when installed. |
Ways to use Drive-by mining
Drive-by mining can be utilized by attackers in several ways:
-
Monetization of Websites: Some website owners may intentionally embed mining scripts to generate revenue, often without disclosing the practice to users.
-
Malvertising Campaigns: Cybercriminals may distribute malicious advertisements that contain mining scripts.
-
Compromised Web Hosting: Attackers can compromise web hosting services to inject mining scripts into numerous websites hosted on the platform.
Problems and Solutions
-
User Awareness: Users can protect themselves by using ad-blockers and antivirus software, which can detect and block malicious scripts.
-
Website Security: Website owners should prioritize security measures to prevent attackers from injecting mining scripts into their sites.
-
Legal and Ethical Concerns: Some countries have considered browser cryptojacking illegal. Regulations and awareness can deter malicious actors.

As the cybersecurity landscape evolves, Drive-by mining will likely continue to adapt to new challenges and technologies. Potential future developments may include:
-
Advanced Evasion Techniques: Drive-by mining may use obfuscation and polymorphism to evade detection by security solutions.
-
Blockchain-based Solutions: Some websites may adopt blockchain-based micropayments as an alternative to Drive-by mining for revenue generation while ensuring user consent.
-
AI-powered Security: AI-driven security solutions may better identify and block malicious scripts, reducing the impact of Drive-by mining.
How proxy servers can be used or associated with Drive-by mining
Proxy servers can play a significant role in Drive-by mining. Malicious actors can utilize proxy servers to hide their identities, making it more challenging for authorities to trace the source of the mining scripts. Proxy servers can also be abused to deliver mining scripts, evading regional restrictions and increasing the potential victim pool. As such, proxy service providers, like OneProxy, need to implement stringent security measures to prevent their servers from becoming a conduit for malicious activities.
