Overall Scanning Traffic Changes Lest the downward trend shown in Figure 2 makes it seem like overall scanning traffic may be abating, it’s important to note that the volume of scanning we observed has remained relatively constant, at least over the last three months, increasing by approximately 5.1% from August to September, then falling approximately…
Read MoreCommon Non-CVE Traffic It may be easy to conclude from the above figures that even though overall traffic has held steady, CVE exploitation attempts, at least for the CVEs and vulnerabilities we track, has decreased. That’s true, but there is a great deal of traffic that our sensor network sees that is not reflected in…
Read MoreZooming Out to Look at 2023 One of the questions we frequently get asked about this data is about attribution, that is, who is doing the scanning. This is a difficult question, because it is quite well understood that many threat actors take great pains to do at least a bit of obfuscation of their…
Read MoreThis view is also notable since it is the first time we’re seeing any of these newly added, high-profile CVEs show up. Second row, far right is CVE-2014-6271, an OS command injection vulnerability more commonly known as Shellshock/Bashdoor. Shellshock shows more targeting variability from month to month than most CVEs (not including CVE-2020-11625, which has…
Read MoreIntroduction Welcome to the February 2024 installment of the Sensor Intelligence Series, our monthly summary of vulnerability intelligence based on distributed passive sensor data. This month’s attack data is, at least in the most seen attacks, much like recent months. We continued to tweak our approach to threat hunting this month and managed to find…
