Cookie Wiping

Cookie wiping, also known as cookie deletion or cookie clearing, is a technique used by attackers to manipulate or disrupt the functionality of web applications by deleting or modifying the information stored in cookies. Cookies are small text files that websites store on a user's computer to track their activities, remember their preferences, or maintain their login sessions.

Attack vector:

  1. Social engineering: The attacker may use social engineering techniques to trick users into deleting or modifying their cookies. This can be done through phishing emails, malicious websites, or other deceptive means, leading users to click on links or download software that performs the cookie wiping.
  2. Malicious software: Attackers may use malware, such as a Trojan or a browser extension, to infiltrate the user's system and gain the ability to modify or delete cookies. This can result in the loss of user preferences or session data, potentially leading to unauthorized access to user accounts.
  3. Cross-Site Scripting (XSS): An attacker may exploit XSS vulnerabilities in a web application to inject malicious code that manipulates or deletes cookies on the user's browser. When the user visits the vulnerable website, the malicious code is executed, and the cookies are wiped or altered without the user's knowledge.
  4. Man-in-the-middle (MITM) attacks: If an attacker is able to intercept the communication between a user and a web server, they may be able to alter or delete cookies in transit. This can be achieved through techniques such as ARP poisoning, DNS spoofing, or SSL/TLS downgrades.

The impact of cookie wiping can range from mild inconvenience to severe security breaches, depending on the importance of the targeted cookies. It can lead to loss of user preferences, session hijacking, unauthorized access to user accounts, or even the exposure of sensitive information. To mitigate the risks associated with cookie wiping, website owners should implement secure coding practices, enforce the use of HTTPS, and utilize security features such as the HttpOnly and Secure attributes for cookies. Users should also be cautious about the websites they visit, the browser extensions they install, and the links they click on in emails and messages.
