What Is Cryptojacking?

So what is crypto-jacking? This is the unauthorized use of your device, or other people’s devices, to mine cryptocurrencies. This is the favorite way for cybercriminals to mine and get their hands on coins if they don’t want to sign up their mining rigs and mine them legitimately.

Malware is used and designed to be imperceptible, so you can’t notice it, and hence it only uses a few of your device’s resources so they can ideally exploit your device’s resources to mine coins for them for a long time before you catch it if you ever catch it.

How Does It Work?

So how does this work? There are two main ways for them to do this, depending on how the malware is designed. First, they can do so by sending a link to your email or text message, and then when you click on it, they download a mining script onto your device. It runs in the background and mines crypto using your CPU or GPU.

For example, and sends it back to the hackers address that they control. Number two is a little bit more common than web-based crypto-jacking. This one, they inject scripts into websites that they’ve taken over or exploited or online ads. So when people visit these sites, the script executes automatically without being downloaded to your computer or mobile phone.

As you can imagine, this is less aggressive because you’re only mining for them as long as you’re on the compromised site.

Common Cryptos Involved With Cryptojacking

So which coins are commonly involved with crypto-jacking? Any proof-of-work point requires you to solve these proof-of-work puzzles constantly and mine for them, for say so Bitcoin, litecoin, Manero for example, but they prefer ones obviously that are easy to mine that you can do so with CPUs and GPUs.

This is why Manero or XM is super popular for crypto hackers and is also untraceable, so that’s a bonus for them. It’s harder for them to get caught by the authorities if they mine and take it in Manero form. Now how does this compare to ransomware because? We’ve heard of ransomware with cryptocurrency attacks – they both give the hacker financial gain.

Still, ransomware is much more noticeable because it locks you out of your computer, and you can’t access it unless you send them Bitcoin to their address. Crypto-jacking, on the other hand, may go undetected for quite a while.

Also, crypto-jacking is less risky because you can exploit a little bit on each device, but do it at a massive scale like millions of visitors or millions of effective devices instead of just ransom wearing like ten people.

So with ransomware, you also have much more contact between the attacker and the victim, which is risky if the hacker isn’t careful when they leave some identifiable information for the authorities to catch them with later.
