What Is A DNS Leak?

Today we are going to talk about what DNS is, including the DNS work principle, and the reason of DNS leak that makes your online information like email, facebook, twitter, tinder, even online bank be hacked.

DNS ??which is short for Domain Name System ??is a distributed database that maps domain names and IP addresses to each other on the World Wide Web. The address on the Internet is a numeric IP address, and the domain name is to memory easily. It enables users to access the Internet without remembering the IP strings that can be read directly by the machine.

The DNS work principle, for example, a domain name: abc.com, is to see this HTTP service. If you want to access the website, you need to resolve it. First, resolve it to a web server through a dedicated DNS server at the domain registrar on the fixed IP 211.221.1., then receive the domain name through the web server, the domain name abc.com is mapped to this server. After that, entering the domain name abc.com to access the website content. That is the whole process of domain name resolution is realized.

There are several main reasons for a DNS leak event, usually due to some form of a configuration error, VPN or network, unblock websites or Microsoft Windows itself. It may also be because of some more malicious incidents, for example, an attacker controls your router.

The main factors that cause DNS leaks:

?Your operating system may have features that interfere with DNS traffic.

?Your DNS is configured to use a DNS server that is not controlled by VPN.

?An incorrect network configuration caused a DNS request leaks.

? Do not support IPv6 address.

Is private browsing safe?

All modern browsers feature a private or incognito mode. It is important to understand what this function does because its name is in many ways very misleading. This can result in people surfing the internet while mistakenly believing their privacy is covered in ways that it is not.

So what can private mode provide? unblock websites
The main purpose of a private browsing mode is to prevent people who have direct physical access to your computer (for example, family members) from seeing your browsing histories. When using Private Mode:
??Websites you visit are not saved in your browser history
??Searches are not stored locally
??Form data are not stored locally
??Cookies are removed when the session ends.

Your browsing sessions are separated from your regular sessions by deleting cookies between sessions.

So what does private mode cannot provide?
Private mode simply does not make you private on the Internet:
??Websites can see the unique IP address of your pages
??Websites can track you with a browser fingerprinting canvas and various other methods instead of using cookies
??The websites you saved will still be kept with records
??There will be logs kept for your browsing histories

Some tips
If you want to go shopping online without letting your family members know what you have bought, or hide your adult viewing habits on a shared desktop, private mode is perfect. After all, for a reason, it is often called VPN mode!

What it does not do is keeping your privacy at your ISP’s palce. To achieve this, use a VPN to mask your IP address, and try some browser add-ons (which might or may not be combined with the above mentioned security browsers), to avoid web monitoring.

The browsers in this list provide more security and are open source than Chrome, Edge / Internet Explorer or Safari.

Browser Encryption is Bypassed by Data Router Malware

A router malware strain that has recently been discovered seems far worse than expected. Cisco Talos found that VPN Filter not only can make devices stop working, but can also circumvent the web-specific SSL encryption. A malware module intercepts outgoing web requests to turn them into unsecure requests (i.e., fundamental HTTP requests), so that they can, when possible, steal sign-ins and other sensitive information. The program can also use someone in the middle to inject hostile JavaScript on external websites and on target computers, such as PCs on a local network outside the router itself.

Much more devices are targeted than first thought. While a late May study centered on a handful of Linksys, MikroTik, Netgear, QNAP and TP-Link routers and network storage devices, the vulnerability now has a known effect on many other product models, including ASUS, D-Link, Huawei, Ubiquiti and upvel.

Moreover, VPNFilter even has a special focus on Ukraine, Symantec noted that it is especially “interested” in the aims of Russia or any other actor politically motivated.

Fortunately, the risk can be reduced or eliminated. MikroTik and Netgear note that more recent firmware updates that intended to protect against VPNFilter and the Domains of Malware used to monitor their network have been taken over by the FBI. QNAP has a tool for removing malware. The magnitude of the threat is rather confusing, however, and many people and companies rarely upgrade their firmware. A new variant may be able to move to a new domain and infect additional hardware.

Additionally, using VPN while surfing online is anther effective way to achieve browser encryption.
