Wi-Fi Router Security: New Hole Found - Disable UPnP

UPnP Security Concerns: A Deeper Dive
Previously, we highlighted the security risks associated with Universal Plug and Play (UPnP) enabled on your router, recommending its deactivation. Recent findings from a security research organization indicate that the vulnerabilities are more extensive than initially assessed.
Widespread Exposure and Device Vulnerability
Currently, approximately 81 million distinct IP addresses are exhibiting exposed UPnP functionality accessible from the internet. This represents a significant security concern.
Over 6,900 different device models are potentially susceptible to external hacking attempts. This broad range of affected devices amplifies the overall risk.
Theoretically, a compromised router could be exploited to establish port forwarding rules, creating an opening for further malicious activity.
Mitigation: Disabling UPnP
The most effective solution is to disable UPnP within your wireless router’s configuration settings.
The specific procedure varies depending on your router model. You will need to access your router’s administrative interface, typically by referencing the device’s manual for instructions.
If you have misplaced or forgotten your router’s login credentials, consult our guide on regaining access even without the password.
