What is Cryptojacking & how to prevent it

Cryptojacking is as cryptic as it sounds, but let’s try to demystify it and find out “What is Cryptojacking & how to prevent it?”

In today’s digital age, filled with smartphones and computers in everyone’s pocket, people do almost all their financial transactions and shopping online.

But every good thing comes with a downside, so if you know the topic of this article, you guessed it right. The downside of increasing financial transactions and shopping online came with the onset of cryptocurrencies. And with cryptocurrencies, a new type of cybercrime arrived at the scene, which is known as Cryptojacking.

The cryptocurrency was, in fact, an accidental invention in 2009 by Satoshi Nakamoto (a pseudonym), who intended to create a centralized cash system but failed. He instead developed a digital cash system based on the accuracy and transparency of accounts, balances, and recording of transactions to prevent double-spending. This innovative, global technology is becoming more widely used and accepted yearly.

But now you may be asking yourself, what is Cryptojacking, and how does the threat of it affect me? Cryptojacking is a massive threat as it implants itself within a smartphone or laptop and then employs measures to mine Cryptocurrency. It happens when someone mines Cryptocurrency from your phone or system without your consent or knowledge.

Cryptojacking first made headlines in September 2017, around the same time when Bitcoin was at an all-time high. Coin Hive, the first well-known Cryptojacking service, consists of a series of JavaScript files that gave website owners a new & creative approach to generating money from existing and new users.

No matter what kind of experience you have with blockchain technology and Cryptocurrency, reading about Cryptojacking is good because it’s the newest cyberattack in town.
