How to Check Your Home Router is Vulnerable or Not

In a world where security threats are populating day by day, it becomes necessary to have a check on every minute technology framework you access in your house. 

Since using up to date, technology will make your experience better and protect your device from various threats.

Cybersecurity nowadays is boosting up due to several problematic incidents that took place in the past. Several measures are required to protect digital data and devices from the online traitors. It consists of helping end-users to stay alert and well informed about the threats and prevention to it. It takes an hour to access internet security technology and keep everything up to date to achieve this.

Further, considering workplace, school, and firms, every individual should adopt internet security to avoid last-minute ways of attack.

Recent Cases

Nowadays, ordinary people’s internet-enabled devices such as routers, webcams, printers, and so on are susceptible to vulnerability and online attacks. These devices that are used by people were used in a massive distributed denial of service (DDoS) attack on October 12, 2016, that left most of the internet inaccessible at the American east coast. 

Higher authorities initially thought that it might be the work of a hostile nation, but then it was found that it was the Mirai botnet’s work. The attack became a great success for the hackers as they targeted the devices in which the default password had not been changed and took control of them. These devices were formed into a massive botnet. This botnet was used to launch the distributed denial of service (DDoS) attack, which sent massive volumes of artificial traffic to all the servers so that the legitimate traffic cannot be served.

For now, the estimated number of connected devices by 2020 has reached 50 billion, and there is a chance that the cybercriminals may attempt a new wave of attack. In such a dynamic environment where risks and new vulnerabilities evolve daily, it is essential to secure your home routers to prevent IoT threats. Hence, to avoid getting attacked, you must make sure your systems or devices are out of risk.

What Does Vulnerability Mean?

Vulnerability is a weakness that can be exploited or controlled by a malicious actor, such as an attacker, to violate the system’s security policy. To use vulnerability refers to getting unauthorized access to the system’s exposure that can be leveraged for malicious activity by attackers.

Why Are Routers Vulnerable?

Firmware is the real problem when it comes to vulnerable routers. There are two aspects to a router. One is the hardware, and the other is the software. The hardware mainly comprises the computer parts inside the case. Meanwhile, the software runs the show. In a router, the software is known to be the firmware, which is what the software is typically called in embedded systems.

As the software can be notoriously tricky to write, even the experts tend to make some mistakes or bugs while writing it. These bugs may seem relatively minor and not harmful, but these bugs also pave the way for the attackers to exploit the system and allow them to do things that they shouldn’t be authorized to do.

How Can You Check If Someone Else Is Using Your Router Network?

The first thing you should inspect will undoubtedly be the Wi-Fi router itself. Check if your Wi-Fi router is open for all. If it is accessible for all, it means that your Wi-Fi is not secure. To ensure its security, you need to set a Security password from your admin panel and choose one security type, such as WEP, WPA, and WPA2. WPA2 is the security type with more than 10 characters. If you set your security type as WPA2 personal, then the only way to break your wireless password is through brute force. 

Hence, this type is preferable for your home routers. This way, you can prevent the Network Adapters from accessing your Wi-Fi. The secondary method is to check the router logs for the devices that are associated with your router. This way, you can find the number of registered devices on your network, and if any of them are not familiar. 

If you see an unrecognized device connected or failed connection attempts from obscure devices, it’s possible that these are hack attempts. The third aspect to look for is unknown SSIDs or Wi-Fi access points that are not broadcasting an SSID, which is not secured and ensure that a device does not host them on your network.

The Router

The router is the known target for hackers who want to access your Wifi network anytime. It means that the hacker can access or redirect your official or personal internet connections to malware-infected servers. 

There are several recorded cases of manufacturers who produce devices but do not bother to update them, leading to an open server attack to the manufactured device. Therefore, it helps several cybercriminals to hack the router and access your wifi network easily.

The threats that malware possess include blocking network traffic, collecting data that passes through the router, and inducing rendering in routers.

No one wants to provide their information to the third party directly. Since cybercriminals can access everything after the router’s hacking, it becomes difficult to retrieve the lost data quickly. 

In this article, we will shed light on the security aspects of a home network, router, and steps to detect if your home router is vulnerable.

Steps To Check If Your Home Router Is Vulnerable Or Not

Here are some necessary steps to check and prevent your router from external malware.

Conduct A Router Authentication Test

Routers permit the organization to use acceptable ports that are possible through the Ethernet link or remote association. However, switches additionally allow associations for different administrations and ports, for example, FTP (port 21), SSH (22), Telnet (23), HTTP (80), HTTPS (443), or SMB (139, 445). 

There are different other notable and utilized administrations whose default ports are set up as web guidelines. The blocked port design may set in your switch as a matter of course.

You can audit it to determine the status and arrangement settings. Similarly, you can empower just the administrations you need and remove unused ports. In any event, for far off associations, aside from where they are fundamental.

Use Strong Passwords

Before activating your router, try adding a strong password for admin followed by the strong username and Use long and complex passwords. Try to use a password manager to create a safe password and store it safely to avoid problems. Moreover, every few days, visit your configuration and port, security passwords to check them.  

Perform Vulnerability Test 

Several tools perform automatic tests to find the router’s weak points and specify any vulnerabilities present in it. These tools give you information, suggestions, and options on how to solve vulnerable problems. So it is preferable to use them to protect your router connections.

Verify Connected Devices To Avoid Threats

The best way to keep your connections secure and away from threats is by keeping track of connected devices. Further, because of terrible practices and weak conventions, it’s functional for gadgets to associate without legitimate approval and for untrusted gadgets to the interface. 

It is smart to know about and ready to distinguish all the gadgets that interface with your router to detect the vulnerability.

Try To Update Devices On The Home Network.

Recently it is seen that a new threat known as KRACK is attacking routers by allowing the interception of traffic between gadgets that are connected to the router. It is advisable to update your device on the home network because it will not allow any malware to intercept the connected systems and updates. Apart from this, always install the updates in the router’s firmware as soon as patches are available.

Security Options 

The most crucial need of an hour is to enable your security options. They are available in the router configuration sections (subject to change according to the model and device).

It will enable more protection to your device and networks. Some of the router’s configurations provide options to protect your device against DoS attacks, SYN flooding, ICMP redirection, etc. It will also help you in detecting any unknown malware in the future.

To Reduce The Risk Of Attack On Your Home Router:

  1. Allow access to the LAN interface. Do not allow access over WAN interfaces.
  2. It is advisable to use a strong password for management and wireless key.
  3. Always keep track of firmware updates and bugs that affect your device.
  4. Always get a  router with a stateful firewall and see if your router can use DD-WRT as the firmware.     

Conclusion

So to wrap it up, it is our responsibility to look after our devices and networks to avoid problematic cybercrimes in the future.
