After receiving a huge amount of attacker attention from November 2022 to February 2023, CVE-2020-8958 has returned to volumes of traffic more consistent with what we’d come to expect over the last year…

Welcome to the Sensor Intelligence Series for April 2023. Last month was comparatively quiet in terms of attack traffic, like March before it. CVE-2020-8958 (an OS command injection vulnerability in a GPON router) remained the top-targeted vulnerability, as it has for nine of the last ten months. Many of the other top targets, such as…

As you can see in Figure 1, six out of the 29 identified CVEs constituted the vast majority (96.7%) of the traffic, so much of our analysis is focused on them. CVE-2017-9841 was the most frequently targeted for the entire six-month period, fluctuating slightly but never enough to fall from the top spot. Below that,…

The stubborn one-way passage of time means that it is time for another round of vulnerability targeting intelligence. Web attacks in May 2023 had a lot in common with those in April, with eight of the top ten vulnerabilities remaining consistent across the two months. In that vein of continuity, CVE-2020-8958, the Guangzhou GPON router…

Cross-site scripting dominated the field of CVEs from 2011-2016, at times making up 60% of published vulns in a quarter. SQL injection…

It seems like threat actors everywhere could detect my impatience last month when I wrote that not much had changed among the 70-odd CVEs that we track for attack trends, because last month they did something. Actually, to be more precise, they stopped doing some things. This is the first month since September 2022 that…
