Introduction Welcome to the September 2024 installment of the Sensor Intelligence Series, our monthly summary of vulnerability intelligence based on distributed passive sensor data. Following on from our last month’s analysis, scanning CVE-2017-9841 continues to drop, falling by 10% compared to August, and now down 99.8% from its high-water mark in June of 2024, and…
Read MoreIntroduction 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%…
Read MoreIntroduction Welcome to the July 2024 installment of the Sensor Intelligence Series, our monthly summary of vulnerability intelligence based on distributed passive sensor data. Last month we observed a massive increase in scanning for CVE-2017-9841 as well as continued increases in scanning for CVE-2023-1389 and scanning for a newly discovered PHP vulnerability – CVE-2024-4577. This…

- by nlqip
Note the large increase in the number of unique source IPs and source ASNs. Between May and June, 38 different source ASNs dropped from the scanning activity, and 179 were added. This is unusual. While scanners will abandon infrastructure as takedowns happen, or access is revoked, they typically do not make such massive changes without…
Read MoreWho Is Scanning for CVE-2023-1389? Back in April, when we first started tracking CVE-2023-1389, we did an analysis of who was scanning for it, and found that the majority of scanning activity was coming from just two ASNs, AS49870 (Alsycon, a hosting provider out of the Netherlands) and AS47890 (Unmanaged Ltd). Running these analyses again,…
Read MoreThe majority of the scanning activity is coming from IP addresses assigned to just a handful of ASNs, mostly AS49870 (Alsycon, a hosting provider out of the Netherlands) and AS47890 (Unmanaged Ltd, what looks to be an IT consulting firm based out of the UK). The scanners appear to be using VPS or other resources…
Read MoreThere are several interesting developments in this plot other than the emphasis on CVE-2018-13379, the vulnerability in the Fortinet SSL VPNs . After growing in prominence to second rank in June and occupying top spot in July and August, CVE-2020-8958 dropped in attack frequency in September to occupy the fourth spot. September was also the…
Read MoreAnother month has passed, which means more sensor telemetry to analyze for attacker targeting trends. October’s data is notable primarily because we detected attackers looking for a handful of interesting vulnerabilities that were recently released or discovered, most notably CVE-2022-41040, one of the Microsoft Exchange zero day vulnerabilities that attackers began to exploit in August…
Read MoreVulnerabilities New and Old Particularly avid readers, or perhaps just readers with a magnifying glass, will note that there are six-and-a-half new vulnerabilities in Figure 3 compared with our November SIS. We say a half-new vulnerability because one of the new ones is indistinguishable from an existing signature. While tuning the pattern for CVE-2022-41040, a…
Read MoreWelcome to the Sensor Intel Series installment for January 2023. The purpose of this recurring monthly brief is to provide security practitioners with vulnerability targeting intelligence so that they can make better-informed decisions about patching and vulnerability remediation. The source of this intelligence is log data from a globally distributed network of passive sensors. While…
