What is pharming?
Pharming is a type of cyberattack that aims to redirect internet users to fake websites where their sensitive data such as user information and banking details can be stolen. This type of attack is particularly dangerous because it can be carried out using both manual manipulation and automated techniques without the user realising it.
How does pharming work?
Pharming usually works by manipulating DNS servers, i.e. the servers responsible for translating domain names into IP addresses. Attackers change the DNS entries so that requests to legitimate websites are redirected to malicious servers instead. These servers are often designed to be identical to the real website, making it difficult for users to recognise the scam.
Types of pharming
- DNS poisoning: DNS servers are manipulated so that they issue false IP addresses.
- Browser hijacking: Malware is installed on the user's computer that configures the browser so that it always redirects to the fake website.
Dangers of pharming
The main danger of pharming lies in the possibility of stealing data. Users who access the fake websites could inadvertently enter their login details and other confidential information. This often leads to identity theft and financial loss.
How can you protect yourself from pharming?
There are several ways to protect yourself from pharming:
- Always keep your operating system and software up to date to close security gaps.
- Use a reliable anti-virus programme that also offers protection against phishing and pharming.
- Be careful with links in emails and messages and always check the URL before entering personal information.
FAQs on the subject of pharming
What is the difference between pharming and phishing?
Pharming is more targeted and less obvious as it redirects users to fake websites without them having to click on a fraudulent link, whereas phishing is usually done via fake emails that target the user directly.
How do I recognise a pharming attack?
Some signs may be a sudden loss of access to known websites or noticeably long loading times of websites. If you are asked to enter your password or personal details when accessing a website, even though you are sure that you have entered the correct address, this could be pharming.
Illustrative example on the topic: Pharming
Imagine Anna wants to log in to her online bank. She enters the correct URL in her browser. However, due to a pharming attack, her DNS server has been manipulated so that she is redirected to a fake website that looks very similar to the real bank. The.URL looks like "www.ihrebank.de", but in reality it is "www.betrugbank.com". Anna enters her user details without realising that she has fallen into the trap. The scammers immediately use this information to access her bank account and steal her money.
Conclusion
Pharming is a serious threat in today's digital world. Protective measures are crucial to guard against the more sophisticated techniques used by cybercriminals. As techniques continue to evolve, it remains important to be vigilant and adhere to best security practices.

Frequently asked questions
To protect yourself from pharming attacks, you should regularly update your operating system and software to close security gaps. A reliable antivirus programme can also be helpful, as it often offers protection against phishing and pharming. You should also be careful when clicking on links in emails and always check the URL before entering any personal details. A secure internet connection and the use of VPN services can also reduce the risk.
DNS poisoning plays a central role in pharming, as it is the technique by which attackers manipulate DNS servers to redirect users to fake websites. This involves inserting false IP addresses into the DNS database so that requests to legitimate websites are redirected to malicious servers. These fake sites often look identical to the real ones, making it difficult for users to recognise the scam and protect their sensitive data.
Common signs of a pharming attack are sudden access problems to known websites, unexpected redirects and unusually long loading times. If you are asked to enter personal information when visiting a website even though you have entered the correct URL, this could indicate a pharming attack. Changes in the behaviour of your browser or inexplicable error messages can also be indications of manipulation.
Pharming differs from other cyber attacks in its subtle approach. While phishing is often done via fake emails that target users directly, pharming involves redirecting users to fake websites without clicking on fraudulent links. This makes pharming particularly dangerous as it is harder for users to recognise and they can unknowingly expose their sensitive data.
Long-term consequences of pharming can include serious financial losses and identity theft. When users enter their details on fake websites, attackers can gain access to bank accounts and personal information, leading to unauthorised transactions. In addition, the loss of trust in online services and banks can lead affected users to withdraw from digital platforms, which can have a negative impact on the entire online economy.
