APIs and Sectors As more APIs are published, both by large enterprises who want to make their data more available (such as Google) and by smaller, industry-specific organizations hoping to generate value, some interesting industry patterns are also emerging. Of the organizations for which we had sector information, social networking organizations made up the largest…

So How Good Are Sectors for Predicting Risk? Based on these analyses, it appears that the answer is “not bad, but it depends.” On one hand, we can identify specific patterns that seem to map to characteristics about those sectors. We already knew that the Retail Trade sector is heavily targeted by attacks that are…
Read MoreWhat Is SQL Injection? SQL injection is a technique used by attackers to gain unauthorized access to one of an organization’s most critical assets: the database that supports its website. In most cases, it is website vulnerabilities that allow an attacker to insert (or inject) instructions where the application is expecting only data. SQL injection…
Read MoreAugust Port Scan Data F5 Labs also analyzes data for TCP ports other than 80 and 443 from the Efflux network. The top 10 ports for August 2022 follow patterns we’ve been seeing for years, with port 5900 (VNC) topping the list, followed by a collection of ports used mainly for remote access (ssh, telnet,…
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 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…
