Cookie wall is a security mechanism that protects the website from cross-site scripting attacks. It is a kind of reverse firewall that blocks communication between different domains and prevents cross-site scripting attacks.
A cookie wall can be used to block all cookies from third parties like Google Analytics, Facebook, Twitter etc., except those needed by the website itself.
The cookie wall technique was developed by Per Thorsheim, who runs the information security blog "Password Safe". He proposed this technique in his blog post titled "Defending against Cross Site Scripting Attacks," which was published on December 2nd, 2010.
Why Do You Need a Cookie Wall?
A cookie wall can be used for fraud purposes, such as carding and identity theft. Carding is when criminals use stolen credit card information to buy goods from online retailers and resell them for cash. Identity theft involves using another person's name and personal information to commit fraud, such as opening new credit accounts or withdrawing funds from existing accounts.
Cookie walls are also used by cybercriminals to hide malware on websites so that they can infect unsuspecting users who visit these sites unknowingly. In some cases, they may also be used to steal login credentials, personal data or other sensitive information.
