How Does Cryptojacking Work?
Cryptojacking attacks typically involve two methods:
1. Browser-Based Cryptojacking
In browser-based cryptojacking, hackers inject malicious scripts into websites or deliver them through infected advertisements. When users visit these compromised websites or click on infected ads, their computers’ processing power is silently hijacked to mine cryptocurrencies. Users remain unaware that their devices have been compromised.
2. Software-Based Cryptojacking
Software-based cryptojacking involves the installation of malicious software or malware on victims’ devices. This can occur through the download of infected files or software bundles, or even through phishing emails containing malicious attachments. Once installed, the malware runs in the background, utilizing the victims’ computing resources to mine cryptocurrencies.
The Impact of Cryptojacking
Cryptojacking attacks have far-reaching consequences:
- Impaired Performance: Cryptojacking significantly slows down the affected devices, causing sluggishness and decreased productivity.
- Increased Energy Consumption: As hackers exploit victims’ processing power, the energy consumption of infected devices rises, resulting in higher electricity bills.
- Financial Loss: Cryptojacking can be financially damaging, as it escalates energy costs, causes premature hardwareFAANG (Facebook, Amazon, Apple, Netflix, Google): An acronym... failure due to excessive usage, and potentially leads to data breaches.
