Phishing is typically used to try to trick users into sharing their login information for secure accounts. Cryptojackers are using similar techniques to trick people into downloading their software.

By doing so they are able to use your device’s computer processing power to remotely mine for cryptocurrencies. Cyberattackers constantly seek vulnerable websites because they know it’s easier to embed malicious crypto mining code. To make sure it doesn’t happen to you, it pays to monitor your most used websites and pay close attention to any changes. The sooner you detect that you’ve been hijacked, the better chances you have to save your device. Cloud services are more complex to hijack, but can still be targeted nonetheless. In general, attackers search through the code or files of an organization in the hope of finding the API keys to access the cloud service. Following this step, they can use CPU resources to mine cryptocurrency, leading to massive increases in electricity and computer power.


And, by the way, if you’re still unsure about the whole cryptocurrency/Bitcoin phenomenon, you’re not alone. John Oliver explains cryptocurrencies quite well in this video if you want to know more.
