NSFOCUS released its H1 Cybersecurity Insights report, which analyzed traffic from January 1, 2018 to June 30, 2018.

Crypto miners

Since the end of March, the number of crypto mining activities has risen sharply compared to the beginning of 2018. Among all crypto miners, WannaMine was the most active, responsible for more than 70 percent of all detected crypto mining activities detected by NSFOCUS.

Recidivist attackers

Among more than 27 million attack sources detected in the first half of 2018, 25 percent were responsible for 40 percent of attack events. This implies that “recidivists” (attack sources found to be repeatedly linked with malicious behaviors) are more threatening than other attack sources.
