The correlation between DDoS attacks and cryptomining

A new NSFOCUS report indicates that the declining price of cryptocurrencies in 2018 prompted threat actors to stop using botnet resources  for cryptomining attacks – as these were getting less and less profitable – and increasingly use them to launch distributed denial-of-service (DDoS) attacks instead.
