Security’s Reactive Response to the Cycle of Threats

We’re into the final quarter of the year, and the cyberthreat landscape continues to be interesting. This week in the Fortinet Threat Intelligence Brief we looked at a number of interesting trends around IoT botnets, continued ransomware problems – both through directed attacks and infected websites, and the spoofing of the Navy Federal US Credit Union.

One interesting thing to note is how attacks tend to move from target to target and region to region in waves. This week, for example, we saw a 4X spike in attempts to deliver a malicious Excel file to deliver the Odin ransomware variant, primarily directed at users in Japan. We also saw a series of attacks aimed at an older vulnerability in some home routers begin to taper off as attackers started to look for something new to exploit.
