What is upnp

This could end up redirecting your traffic to a different website, setting up endless possibilities for data theft and fraud. Ultimately, it is a matter of opinion.

UPnP is convenient but does bring with it some quite serious security flaws, some of which cannot be mitigated by security solutions. If you use port forwarding occasionally, then you should consider forwarding without the use of UPnP, which is entirely possible. The heavy port forwarding users will have a decision to make. Are you willing to give up security for the convenience of UPnP? The chance that you will be compromised through UPnP is fairly small, but the consequences could be great.

Whilst it is usually recommended that you disable UPnP on your router as many do out of principle , some have questioned whether this is necessary. When UPnP first came onto the scene in , there were some glaring implementation issues that allowed configuration from the internet. This meant that anyone could open any port on it. Over the last decade, however, the software vulnerabilities in the routers have been patched numerous times with security in mind.

UPnP, therefore, is not inherently dangerous if your router is up to date and has all the latest firmware updates, and your connected devices are free of malware. UPnP becomes an issue if a connected device is infected with malware, as it can spread to your local devices.

You can disable UPnP on your router if you want peace of mind. Many IT teams and tech-conscious people hate the idea of having to admit defeat to cyber-attackers. But the sad truth of the matter is that the attackers will always be able to navigate the security defences. You can keep an eye on what the attackers are after in the first place, the data.

UPnP is a convenient way of allowing gadgets to find other devices on your network and if necessary modify your router to allow for device access from outside of your network. Via the Internet Gateway Device Protocol, a UPnP client can obtain the external IP address of for your network and add new port forwarding mappings as part of its setup process.

This is extremely convenient from a consumer perspective as it greatly decreases the complexity of setting up new devices. Unfortunately, with this convenience have come multiple vulnerabilities and large-scale attacks which have exploited UPnP. However, this convenience factor provides an opening for hackers. In the case of Mirai, it allowed them to scan for these ports, and then hack into the device at the other end. Around since , QakBot infects computers, installs a key logger, and then sends banking credentials to remote Command and Control C2 servers.

This is a stealthy approach in post-exploitation because it makes it very difficult for IT security to spot any abnormalities.

After all, to an admin or technician watching the network it would just appear that the user is web browsing — even though the RAT is receiving embedded commands to log keystrokes or search for PII, and exfiltrating passwords, credit card numbers, etc. The right defense against this is to block the domains of known C2 hideouts. Of course, it becomes a cat-and-mouse game with the hackers as they find new dark spots on the Web to set up their servers as old ones are filtered out by corporate security teams.

It has introduced, for lack of a better term, middle-malware, which infects computers, but not to take user credentials!

In effect, the entire Web is their playing field!
