If your mobile browser looks slower than usual, then there's a chance to do secret mining. As the popularity of crypto-money increases, hackers target new types of devices by running malicious code into smart headphones, smart refrigerators and TVs, who stay open around the clock. The phenomenon is called crypto jacking, and has affected both consumers and large organizations. Depending on the attack, users may notice a slight delay in their devices, usually not enough to think they have been hit by an attack hacking.
Hackers try to use the processing power of the victims, as that is what they need to make me cryprobes. During virtual currency mining, computers perform complex calculations to verify the current ledger.
Crypto jacking is not only possible through a malicious program. It can also be done through the browser, as long as the code will run within a page. Several sites tried to remove ads and replace them with a script that they do. According to experts, the crypto jacking began to be considered a threat to 2017 when the price of all cryptosmiths rose dramatically, with Bitcoin's price reaching almost 20.000 dollars.
Avast data shows how fast the increase was, when in September 2017 the crypto jacking threats were 147.704, while in December 3 months later reached 22.4 million. In May of 2018 the number exceeded 93 million.
Detecting the hacker that may be behind a crypto jacking malware is quite difficult, as the currency used (Monero) is 100% encrypted and secure.
While Apple and Google have already removed apps from their mining app stores (hidden or not), the risk continues to be large.
