Mining cryptocurrencies with a PC is dangerous. The mining process requires a huge computer processing power which is accompanied by massive electrical power. It’s this processing power and electrical energy consumption that has gotten the attention of McAfee’s chief consumer security, Gary Davis. Gary observed that more than 1billion devices may be cryptojacked already.
Currently, the art and science of mining has improved both in simplicity and complexity. With tools available to mine over the web commonly referred as web-based mining, individuals are mining cryptocurrencies with a PC. Rogue individuals and firms are taking advantage of web-based mining and they are infecting unsuspecting computers with codes that make mining cryptocurrencies with a PC, remotely without the knowledge of its user. This is called cryptojacking.
“A device that is “cryptojacked” could have 100 percent of its resources used for mining, causing the device to overheat, essentially destroying it.” Said Davis. Earlier this week Apple Inc. removed an app from its App store after it was discovered it was being used to secretly mine without the consent of its users. The app was later restored to the app store after its developers removed the mining code.
To make sure you are not mining Bitcoin, Litecoin, Ethereum or any other coin unknowingly, there are three things you should always take into consideration.
One: Be extra sensitive when using public Wi-Fi networks, whether in schools, café, public transport etc. Public Wi-Fi networks are being hacked and the information of the computers stolen. The information is later used to cryptojack the devices.
Two: Security updates. All your devices (mobile phones and PCs) should be protected with the latest security software.
Three: Virtual Private Network. This is a software code that helps hide your personal information and encrypt messages you send on an unsecured network. This gives cryptojackers a hard time when they try to intercept your device/personal information over a public network.
Have you ever been cryptojacked? How did you know?
