How to Bypass Blocked Sites? Here are 4 Easy Ways

Are you at work or school when you suddenly want to open Facebook or YouTube, but unsurprisingly all sites are blocked? You still have options, however. Simply learn how to get around blocked websites at work, school, or home.

How to bypass a blocked website with VPN?

Utilizing a Virtual Private Network (VPN) is the best route to take. They\’re not as complicated as they originally seem, despite the fact that you\’ve probably heard a little about them.

VPNs use encryption to further enhance security and privacy. That can be helpful if you\’re entering sensitive data and are concerned about hackers. But in this situation, VPNs can be utilised to get around restrictions. These networks allow you to access websites through a \”tunnel,\” which scrambles all data passing across it.

VPNs are bundled with some security suites. Some people can get them for nothing. Some people charge. Although it\’s a good idea to compare prices, we have a list of the best VPNs you can use to stay protected while browsing online.

 How to bypass Firewalls Using Proxies?

Most people consider proxy servers and VPNs to be the same thing. However, the software that encrypts most of your data is not present in proxies. But that does not mean they are worthless!

By showing the IP address of another server, proxies mask your Internet Protocol (IP) address, which can be used to identify your machine and make your searches anonymous.

To get beyond firewalls, there are literally thousands of proxy websites. You will be inundated with results from web searches for both free and paid services. For sporadic use, the former is suitable. But think about whether it\’s worth paying for if you plan to use it frequently (and want something safer and more anonymous).

How to bypass websites using Cached Content

Search engines cache content when indexing websites. Think of it as a carbon copy of a webpage.

Just enter the page you\’re looking for into a search engine and click on the downward arrow by a site\’s name, then on Cached. Alternatively, type cache: into the search box then the URL you want to access.

There are limitations: formatting is generally lost and videos might not play. Nonetheless, this is a good way of getting around blocks. A lot of administrators will have also prohibited cached content from unreliable sources, so this won\’t work on all blacklisted sites. However, it might be possible to get around barriers when conducting research, for example, in schools. Some universities employ automatic filters that may detect content from regular addresses but may not always do so from related URLs.

Access Blocked Websites with Remote Access

Remote access carries a negative reputation. You often imagine hackers gaining access to your device and using it for bad reasons right away. Or you might remember the last time you had to call a computer helpline to have someone else fix a troublesome PC issue. It\’s not all horrible, though.

Remote access is the ability to use your home computer without being physically present in front of it.

It doesn\’t really matter if you use well-known remote connectivity applications like LogMeIn or AnyDesk one of the less well-known ones; you\’ll need to download a helpful piece of software to accomplish this.

Note: There are times when websites are restricted for security reasons because they harm your device. Before attempting to get around the blocks, properly research the stuff you want to access.

If you\’ve discovered avoiding a block, you\’ll most likely get into plenty of problems. That can involve a warning and more monitoring at work. You might be subject to suspension or, in more serious situations, removal from class if you\’ve attempted to bypass a school firewall.

What is DNS Cache Poisoning? How it will harm you? 

by with One Comment Cyber Security

Did you know that DNS cache poisoning can compromise the servers of your ISP, your router, and potentially your computer? This guide is on how to prevent that.

As people become more aware of the risks associated with using the internet, cyber attackers have stepped up their efforts to trick users into providing their data. One of the cheekiest ways to take over a user\’s surfing experience and direct them to a malicious website is via poisoning the Domain Name System (DNS) cache, often known as DNS spoofing.

So let\’s explore DNS cache poisoning\’s mechanism of action and how to prevent them.

What is a DNS Cache?

First, let\’s study the DNS cache and also how URLs and IP addresses work.

Typically, you enter a website\’s URL to access it. You would type www.youtube.com into your browser if you wanted to see youtube videos online. 

Your system doesn\’t actually \”talk\” in URLs, which is the problem. However, it is aware of IP addresses, which are the sets of numbers that serve as a computer\’s \”home address\” on the internet. We use URLs because we find it far simpler to remember a website\’s name than its IP address.

How do DNS Servers work?

Your computer must convert your URL into an IP address it can use in order to determine where you want to go. It does this by sending a request for your URL to a DNS server.

For websites, the DNS server functions as a massive phone book. Your computer sends the URL to the DNS server, which then searches its database to find the appropriate IP address. Your computer is then informed of the IP address.

Now that your computer is aware of the IP address linked to www.youtube.com, it can access the website.

How does a DNS Cache Works?

Since IP addresses rarely (if ever) change, your computer decides to save this information. It records in a DNS cache the IP address for the URL www.youtube.com.

Your computer no longer needs to use the DNS server when you access your bank in the future. The IP address it last received can be found when it searches through its cache. The DNS cache functions much like a small phone book for all of the websites you\’ve already visited.

Now we know what is a DNS Cache and how it works, Let\’s see how hackers can poison it.

If the IP address has changed since the last time it was used, a computer using a DNS cache won\’t know about it. The DNS cache can be thought of as the computer\’s memory; if the values in the cache are changed, the computer will behave as if that is how it has always been.

Consider a scenario in which a malicious agent chooses to target www.youtube.com visitors. They build a fake website that matches the actual one of these in order to collect user information from those who visit this fraudulent website, they also fabricate a login screen.

Once the website is operational, they attack users\’ DNS cache. They can enter someone\’s PC or use malware to accomplish this. In either case, their objective is to access the DNS cache and discover the location of www.youtube.com. Once inside, they replace the bank\’s actual IP address with that of the fictitious website they set up.

Say someone attacked your cache and switched the IP address for your bank. Your computer now searches its cache when you input the bank\’s URL. Your browser is sent to the fake site after it discovers the malicious IP address the hacker set.

A hacker who gains access to a DNS server can change the database and reroute users to whatever location they like. Now, a poisoned result will be returned to every computer querying the DNS server to obtain an IP address.

Can DNS servers be poisoned?

 Unfortunately, the answer is yes. It is possible for a hacker to poison a server instead, given that machines communicate with DNS servers to obtain addresses.

Similar to how your computer works, DNS servers also operate. When it receives a request for an IP address and is unsure of how to respond, it will contact another DNS server for assistance. These servers keep information in their own caches.

A hacker who gains access to a DNS server can change the database and reroute users to whatever location they like. Now, a poisoned result will be returned to every computer querying the DNS server to obtain an IP address.

Even worse, servers that don\’t already know a website\’s IP address may ping the poisoned server to get the information. As a result, they get a poisoned response! As a result of spreading this false information, DNS servers will become infected in a destructive chain reaction.

How to Avoid DNS Poisoning?

Despite how terrifying DNS spoofing may sound, there are techniques to prevent it. Let\’s examine some ways to keep attention when online.

  1. Keep Your Antivirus Active and Up-to-Date
  2. Keep suspicious files off your computer
  3. Use a Reputable ISP or DNS Server
  4. Restart Your Router to Clear Its DNS Cache
  5. Double-Check All Websites You Visit
  6. Flushing Your DNS Cache

DNS servers can speed up your browsing, but they can also cause a lot of harm if they are compromised. Fortunately, there are several things you can do to prevent DNS cache poisoning attacks and any potential pharming they might cause.
