Using an AI powered network traffic analysis tool we built called SIFT, GreyNoise has caught multiple anomalous network payloads with zero-effort that are attempting to disable TrendMicro security features in ASUS routers, then exploit vulnerabilities and novel tradecraft in ASUS AiProtection features on those routers.

VPN: phone, not desktop. WiFi: N/A. These statements are correct. Or at least as correct as is applicable to the general user in the scope of the following contextual blog which generally recommends that:

Recently Sift caught an interesting payload. As it turns out, the exploit was CVE-2024-0769, which is now tagged here: D-Link DIR-859 Information Disclosure Attempt .

In order to see CVE-2023-50164 in the wild, I expect that in the coming weeks, we will see research into vendor and product specific implementations leveraging Apache Struts2 in order to determine exactly what path must be traversed to in order to drop a web shell so that it can be called remotely through a public interface over the defined routes.

At GreyNoise we work with network protocols. When a new vulnerability is published we are quick to jump into investigation mode and gather any and all resources we can find in order to write a tag and provide messaging to our customers and community. GreyNoise doesn’t have much common need to detailed firmware analysis. If it’s happening on the internet, we already see it. However, when we do need to investigate vulnerabilities in embedded devices things can get very complicated very quickly if no information is publicly available. It can be fun and insightful to learn these skills for the rare case we need them.
