Kaspersky Lab, the Russian cybersecurity company, has informed its users about new ransomware attacks – in this case, a malicious file locks a computer until a ransom is paid – have declined by half as the perpetrators start to deploy crypto-mining malware instead. According to the report, it happens due to the fact that crypto-mining is now more profitable than ransomware.
Kaspersky compared data from April 2016–March 2017 with data from April 2017–March 2018. It found that ransomware decreased by almost 45% from 2017 to 2018 whereas crypto-mining increased by 44.5% in the same period.
The Lab expects the growth of these numbers, particularly with the advance of mobile miners. Residents of China and India have roughly one third of all smartphones worldwide, and therefore the company expressed particular concern for them.
