Cryptojacking Explained - Everything You Need to Know about Silent Digital Robberies

In the ever-evolving cybersecurity landscape, cryptojacking has emerged as a growing threat. This article delves into the realm of this digital menace with a comprehensive yet accessible overview.

1. What is Cryptojacking?

Cryptojacking is a cyberattack where a threat actor piggybacks on a victim's computing resources to mine cryptocurrency without their consent.

This term, a portmanteau of 'cryptocurrency' and 'hijacking,' succinctly describes the stealthy and unauthorized mining operations. Cryptojacking gained prominence following the advent of Coinhive, a script introduced in September 2017 that facilitated cryptocurrency mining through web browsers.

2. The Evolution of Cryptojacking

Since its inception, cryptojacking has evolved from a novel exploit into a widespread cybersecurity concern. Initially, attackers used it mainly to commandeer individual computers.

However, the technique quickly escalated to compromising entire networks and cloud infrastructures. The threat’s evolution reflects the adaptability of cybercriminals and the alluring profits of clandestine cryptocurrency mining.

3. Distinguishing Legitimate Mining from Cryptojacking

It's crucial to differentiate between legitimate cryptocurrency mining and cryptojacking. The former is a legal and intentional process where individuals or companies use their resources to mine cryptocurrencies. In contrast, cryptojacking is inherently non-consensual and illegal.

Understanding this distinction is vital to recognizing the digital currency landscape's ethical and legal boundaries.

4. Exploitation by Cybercriminals

Cybercriminals execute cryptojacking by embedding malicious scripts into websites or using phishing-like tactics to install mining software on unsuspecting users' devices.

Once installed, these scripts or software leech the device's processing power to mine cryptocurrencies, often lowering performance while increasing energy consumption for the victim.

5. Guarding Against Cryptojacking

To safeguard against cryptojacking, users and organizations should consider the following recommendations:

  • Regularly update software and operating systems to patch vulnerabilities.
  • Utilize antivirus and anti-malware solutions with cryptojacking detection capabilities such as Bitdefender Ultimate Security.
  • Implement ad-blockers or browser extensions that specifically target and block mining scripts.
  • Stay vigilant against phishing attacks, a common vector for cryptojacking software.
  • Conduct regular network monitoring to detect unusual activity indicating unauthorized mining.


Cryptojacking represents a nuanced and modern cyber threat, blending the worlds of cryptocurrency and cybercrime.

Understanding its mechanisms, evolution, and how it differs from legitimate mining practices is critical to recognizing and preventing such attacks. By staying informed and vigilant, both individuals and organizations can better protect themselves in today's digital era.
