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…
Read MoreIn this list, we don’t see any of the significant factored software types, so there are no weights to add here. Calculating the Likelihood of Exploitation of a Vulnerability Now that we have all our factors and weights, we can do some simple math in a spreadsheet. Factor Weight Base -6.18 Web related 0.06 Reference…
Read MoreAnother interesting aspect of Figure 3 is identifying when vulnerabilities drop off for periods of time. In October we identified two recently released vulnerabilities, CVE-2022-40684 and CVE-2022-41040, in our logs. Both are severe vulnerabilities; CVE-2022-40684, an authentication bypass vulnerability in various Fortinet security appliances, has a CVSS 3.1 score of 9.8, and CVE-2022-41040, an escalation…
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…
Read MoreAlso 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…
Read MoreHere we are in April 2023, which gives us another opportunity to see what vulnerabilities attackers were most interested in last month. 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…
Read MoreWelcome 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…
Read MoreThe 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…
Read MoreThe 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…
