Introduction Welcome to the August 2024 installment of the Sensor Intelligence Series, our monthly summary of vulnerability intelligence based on distributed passive sensor data. Last month, we observed the scanning for CVE-2017-9841 fell sharply, and this month is no different, with scanning for that vulnerability falling another 79% from July’s rate. Overall, it’s down 97.4%…
