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%…

Introduction 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…

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…

Who 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,…

The 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…

Vulnerabilities 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…

Welcome 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…

Also notable this month is the dramatic growth in CVE-2020-25078, which is also an IoT vulnerability but this time in several IP cameras. On the one hand the volume of traffic scanning for this vulnerability was not remarkable, with ~3600 connections in February, but only 200 connections were attempted in January, which means traffic increased…

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…

The most glaring example of a predominant vulnerability type is visible in the top row, which is CWE-79: Improper Neutralization of Input During Web Page Generation, more commonly known as cross-site scripting (XSS). Cross-site scripting dominated the field of CVEs from 2011-2016, at times making up 60% of published vulns in a quarter. SQL injection…
