Instead of directly stealing personal or financial information, cryptojacking focuses on exploiting computational power.
How Does Cryptojacking Work?
Cryptojacking typically occurs in two ways:
- Script-Based Attacks: In this method, attackers inject malicious JavaScriptTor (The Onion Router): Free software for enabling anonymous... code into websites or online ads. When a user visits an infected website or interacts with the compromised ad, the code executes in the background, using the victim’s CPU power to mine cryptocurrencies.
- Malware Infections: Cryptojacking malware is designed to infiltrate a victim’s computer or network. Once inside, the malware silently deploys specialized mining software that siphons off the computational resources, leading to increased power consumption and decreased system performance.
The Rising Threat of Cryptojacking
Cryptojacking has become a lucrative avenue for cybercriminals due to the anonymous nature of cryptocurrencies and the difficulty in tracing mining activities. Here are some reasons why cryptojacking poses a significant threat:
- Ease of Execution: Cryptojacking attacks can be launched with minimal technical expertise. Ready-to-use cryptojacking kits are available on the dark web, allowing novice criminals to partake in this illicit activity.
- Massive Profit Potential: Cryptocurrencies like BitcoinDark Web: Parts of the internet that are not indexed by trad..., Monero, and EthereumSmart Contract: A self-executing contract with the terms of ... can be mined through cryptojacking.
