Introduction Welcome to the October 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 of CVE-2017-9841 has fallen to barely a trickle. CVE-2023-1389, an RCE vulnerability in TP-Link Archer AX21 consumer routers, which has been consistently towards…
Read MoreIntroduction 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…
Read MoreNote 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 MoreStandard mobile banking trojans post their own fraudulent content over banking applications. The Yasuo-Bot malware takes it a step further by dynamically pulling fraudulent content from the C&C server. Since 2010, mobile malware is on the rise. The first mobile Trojan launched was Zitmo (Zeus in the mobile), a mobile version of the most…
Read MoreThe encapsulated IP packet header uses the same parameters as the encapsulating IP header. The Transport Layer protocol for the encapsulated IP packet is UDP. Most public routers will pass along the GRE packet because it’s a widely used protocol for generating VPN connections. We speculate that GRE might be the protocol of choice due to…
Read MoreThe latest evolution of cyber weaponry is brought to you by the default passwords in Internet of Things (IoT) devices. That includes just about every conceivable modern electronic device—from home thermostats, lighting systems, refrigerators, cars, and water meters, to personal fitness devices, toasters, bicycle helmets, toys, and even shoes and clothing. Today, the number…
