Searching for Exposed ASUS Routers Vulnerable to CVE-2021-20090
Over the past 7 days, my honeypot captured a few hundred POST for a vulnerability which appeared to be tracked as a critical path traversal vulnerability in the web interfaces of routers with Arcadyan firmware. If successfully exploited, could allow unauthenticated remote actors to bypass authentication and add the router to the botnet Mirai botnet.

distribute malware. Even if the URL listed on the ad shows a legitimate website, subsequent ad traffic can easily lead to a fake page. Different types of malware are distributed in this manner. I've seen IcedID (Bokbot), Gozi/ISFB, and various information stealers distributed through fake software websites that were provided through Google ad traffic. I submitted malicious files from this example to VirusTotal and found a low rate of detection, with some files not showing as malware at all. Additionally, domains associated with this infection frequently change. That might make it hard to detect.
