To better understand this phenomenon, let's start with the definition of mining.
Mining is a process by which cryptocurrencies are created using the proof-of-work algorithm. Miners verify the authenticity of data in blocks, and if confirmed, receive commissions in crypto.
Now let's get back to the main topic of this post. There is a practice called "cryptojacking" that is used by savvy attackers who can infect unsuspecting users' computers, smartphones, and tablets.
These attackers are interested in your device's computing power because mining alone is expensive and not profitable unless using powerful resources.
A mining virus can be detected in two ways:
Malware: this is the case when you accidentally download a pirated file containing a virus, or follow a suspicious link in an email. The virus then silently consumes your system's resources.
Malicious scripts (drive-by cryptomining): this is a newer and more complex approach to "infecting". Hackers inject pieces of JavaScript code onto websites to start mining as soon as you visit the site.
Initially, websites honestly asked users for permission to mine while they browsed content. It was a transparent way to monetize the site: users received free content in exchange for their resources, and content creators exploited crypto for their bread. Over time, of course, they stopped asking for permission.
