How do Pharming works?
- A common technique requires installing malware on the victim’s computer. It can happen when you visit fraudulent websites or download content from them.
- After the malware installed, it corrupts certain information on the victim’s computer, which in turn triggers the pharming attack.
- Computers keep a list of previously visited websites and IP addresses in a locally stored “hosts” file.
- The next time a user visits a saved website, the computer no longer has to request the IP address from the DNS server but can access the hosts’ file.
- Pharming malware changes the IP address stored in the hosts’ file so that the computer transmits data to the fake website instead of the real website.
How to protect yourself from Pharming?
Fortunately, there are some tried-and-tested strategies to protect against pharming attacks
- Choose a Trusted Internet Service Provider (ISP) – Most leading ISPs automatically filter pharma redirects to prevent you from entering the pharming website.
- Check URLs for typing errors – when you visit a website, wait for it to load and take a close look at the URL.
- Confirm that the URL starts with HTTPS – If a URL begins with HTTPS, then all the traffic between you and the website are encrypted. It is vital for financial and stock exchange transactions.
Stay away from dubious websites – use common sense when surfing the web.
- Take a close look at websites before you do anything – If a trusted website looks different than usual, you may be on a pharmacist’s version.
- Avoid links and files from unknown sources – be careful when downloading files and do not click on dubious links.
