What is Cryptojacking
Cryptojacking is defined as the secret use of your computing device to mine cryptocurrency. Hackers engage in cryptojacking when they use a user’s browser to harvest cryptocurrency like Bitcoin. Sometimes cryptojacking used to be confined to the victim unknowingly installing a program that secretly mines cryptocurrency.
As we can read on Digiday, each addition to the ledger creates more of the currency, so having access to computing power is essential for anyone trying to make a lot of money from cryptocurrencies.
The most infamous examples of cryptojacking occurred this fall when hackers injected their mining code into the websites of publishers without the publishers’ knowledge.
How Cryptojacking works?
How to protect yourself?
If you’re on a desktop or laptop with lots of processor speed and memory, you might not even notice in-browser cryptojacking. The simplest way to protect yourself from cryptojacking is to install a simple cryptojacking blocker. Installing a crypto jacking blocker means adding a browser extension that blocks a list of domains associated with jacking code.
As Hackerbits said “NoCoin is currently the most widely installed extension. Rafael Keramidas, the extension author, created extensions for both Chrome and Firefox.”
But it works both ways. Coinhive, the cryptojacking software that’s used in the Archive Poster extension, is available to download and is advertised as a way to “monetize your business with your users’ cpu power”. However, websites and software that use it without a clear and visible warning to users are usually frowned upon at the very least.
