F-Secure Attack Landscape H2 2019

2019 wrapped up with high-impact ransomware attacks on enterprises, as well as continued high rates of attack traffic throughout our global network of honeypots. Honeypot traffic was driven by action aimed at the SMB and Telnet protocols, indicating continued attacker interest in the Eternal Blue vulnerability as well as plenty of infected IoT devices. The end of the year also served as the end of the decade, prompting a look back at where we’ve come since 2010.

In this report, we cover the attack traffic seen by our global network of honeypots over the last six months of 2019, as well as malware seen by our customer endpoints throughout the year. We also take a trip down memory lane, revisiting cyber security highlights of the decade.
