DNS poisoning: an attack technique used by cybercriminals
1. Introduction.
DNS poisoning is an attack technique that can be used by cybercriminals to redirect Internet traffic to malicious websites and obtain confidential information from users.
In this new FlashStart Blog entry, we will explore what this technique is about, its possible consequences, and how we can protect ourselves against it. From the perspective of computer security, DNS poisoning is a relevant and current topic that requires several measures to diagnose and take preventive actions.
2. Understanding DNS Poisoning
DNS poisoning is a malicious technique used by cybercriminals to redirect users to malicious or fake websites. This technique exploits a vulnerability in the Domain Name System (DNS), which is responsible for translating domain names into IP addresses. DNS poisoning is a form of identity theft attack that can be very dangerous, as it can allow attackers to steal personal, financial, or confidential information.
To better understand DNS poisoning, it is important to understand how the Domain Name System works. When a user enters a website address in their browser, the browser sends a request to the DNS server to obtain the corresponding IP address.
However, in a DNS poisoning attack, an attacker tries to intercept the browser’s requests and sends a false response to the DNS server. The false response contains an incorrect IP address that redirects the user to a malicious or fake website. The user may not realize that they have been redirected to a fake website and may enter confidential information, such as passwords or financial information. Generally, these types of attacks are combined with others, such as phishing.
Currently, most websites use HTTPS as a secure connection method. It is very common to encounter such attacks when accessing our sites, and the browser alerts us about errors in certificates or even when the site does not have any certificates. In such cases, it is better not to enter any personal information. However, if you have already done so, it is important to change passwords on those sites.

3. Impact of DNS Poisoning: The consequences of this type of attack.
The impact of DNS poisoning can be very dangerous if we have already been deceived with this technique since attackers can redirect users to fake websites that appear legitimate but are actually designed to steal personal and financial information. Attackers often use this technique to carry out phishing attacks, install malware on the user’s computer, or even hijack the browsing session.
DNS poisoning is a highly sophisticated and difficult-to-detect technique, so it is important for users to be aware of the necessary security measures to protect themselves against this type of attack. Some measures that can be taken include using secure DNS servers, regularly updating system software, and using security tools such as firewalls and antivirus software.
4. Protective measures against DNS poisoning.
One of the most effective measures is to use reliable and secure DNS servers. DNS servers are responsible for translating domain names into IP addresses. If a DNS server is poisoned, it can redirect traffic to malicious websites. Therefore, it is important to use reliable and secure DNS servers, such as FlashStart. FlashStart not only provides a secure DNS server but also protects you from these types of attacks, ensuring your network’s safety with our advanced AI-based filters.
It is also recommended to use HTTPS connections instead of HTTP (although it is not as common to encounter insecure sites anymore) whenever possible. HTTPS connections use secure encryption that protects the user’s information from being intercepted by third parties. Always remember to verify the certificate of a site to confirm its authenticity.
5. The future of DNS Poisoning attacks.
In recent years, DNS poisoning attacks have been a constant concern for businesses and online users..
As technology advances, DNS poisoning attacks also evolve and become more sophisticated. That’s why it’s important to stay aware of the trends and future of these attacks in order to adequately protect oneself.
One emerging trend in DNS poisoning attacks is the use of machine learning techniques and big data analysis by attackers to identify vulnerable targets and customize their attacks. This means that attacks will be more precise and effective, increasing the risk for businesses and users. You can check our website to see real-time internet attack types.
Another trend is the increasing use of IoT (Internet of Things) devices as attack vectors. IoT devices often have weak security measures and are easy to compromise, making them attractive targets for attackers. Home cameras or IoT sensors are common vectors; always remember to keep the software updated and never leave default passwords. It’s important to prevent these types of attacks by designing the network accordingly, for example, by segregating networks using VLANs for specific network resources.
It’s important for businesses and users to take measures to protect themselves against these attacks, such as keeping their systems up to date and using advanced security solutions. Additionally, it’s necessary to stay informed about emerging trends in this type of attack to anticipate and prevent future risks.
