What is Cryptojacking? Understanding the Digital Hijack
A blog post by Cyber Search.
Introduction to Cryptojacking
Cryptojacking is a cyberthreat that has garnered significant attention in recent years. It involves the unauthorized use of someone else's computer to mine cryptocurrency. Hackers use various methods to infiltrate computers or even entire networks and then install crypto-mining software without the consent of the owners. This not only slows down the affected systems but also subjects victims to potential privacy breaches and financial losses.
How Cryptojacking Works
Cryptojacking can occur in several ways. One common method is through phishing-like tactics, where users are tricked into clicking a malicious link that then installs crypto-mining code on their computer. Alternatively, hackers can inject a script on a website or an ad that runs on computers that access that site. Once the code is in place, it works in the background secretly, mining cryptocurrency for the attacker while using the resources of the host device.
Detecting and Preventing Cryptojacking
Detecting cryptojacking can be difficult since it's designed to be unobtrusive, but some signs include a noticeable slowdown in device performance or overheating. To prevent cryptojacking, it's important to use cybersecurity software, keep all systems updated, employ browser extensions designed to block mining scripts, and maintain a high level of awareness about this type of threat. Regular system monitoring and awareness can go a long way in protecting oneself against this subtle yet harmful cybercrime.
