Hidden mining threat (CryptoJacking) reached a record level in first half of 2022: number of detected attacks raised to 66.7 million, 30% more than in first six months of 2021
Hidden mining or CryptoJacking is a cybercrime. It involves unauthorized use of devices (computers, smartphones, tablets or servers) by hackers to mine cryptocurrency. Hidden mining is often done through security exploits in mobile apps. As well as web browsers and goes unnoticed by victims.
Cyber security company SonicWall recorded 45.1 million attacks in the first quarter. This is their highest number in their history of monitoring. However, in Q2 there were half as many cases – 21.6 million. According to a study, falling prices for cryptocurrencies may be a reason for this. According to experts’ forecast, the “summer recession of CryptoJacking” will continue in Q3 of this year. But attacks will peak again in Q4.
What drives growth of hidden mining and why it is dangerous

Normal users see their devices running slower. But it’s hard to connect this to criminal activity.
At least one extortion group has already publicly announced its intentions to switch to hidden mining. And if they do, it won’t be the first time cryptojacking has replaced extortion software.
The number of attacks on government, health care, and education sectors decreased by 78%, 87%, and 96%, respectively. However, cases of hidden mining in financial industry increased by 269%, and in retail by 63%.
