Name: wajeeh ul hassan Subject: Cyber Security Teacher: Sir Mahmood Anwer Cross Site Scripting Hacking Terminology Impact of XSS Attacks 1. Data Theft Attackers can exploit XSS vulnerabilities to steal sensitive information such as user credentials, personal data, and financial details stored in cookies or web application databases. 2. Session Hijacking: By injecting malicious scripts into web pages, attackers can hijack user sessions, gaining unauthorized access to accounts and performing actions on behalf of the victim. 3. Website Defacement: XSS attacks can be used to modify the content of web pages, leading to website defacement. This can damage the reputation of the organization, erode trust among users, and result in financial losses. 4. Phishing Attacks: Attackers often use XSS to launch phishing campaigns, tricking users into revealing confidential information or downloading malware by presenting them with fake login forms or malicious links. 5. Loss of Customer Trust: Successful XSS attacks can undermine the trust users have in the security of a website or web application. This can lead to loss of customers, damage to brand reputation, and legal repercussions. Real-World Examples 1. Samy Worm (MySpace, 2005): Samy Kamkar created a self-propagating XSS worm on MySpace, exploiting a vulnerability in the platform's profile feature. The worm spread rapidly, adding Kamkar as a friend and appending "but most of all, Samy is my hero" to infected profiles. It resulted in widespread disruption and highlighted the potential for XSS to cause significant harm. 2. Twitter Worm (2009): In 2009, a XSS worm hit Twitter, spreading via tweets containing malicious JavaScript code. When users clicked on infected links, the worm automatically retweeted itself, causing a cascade effect. The attack exploited a vulnerability in Twitter's handling of JavaScript in tweets, demonstrating the impact of XSS on social media platforms. 3. Gmail XSS (2007): A security researcher discovered a XSS vulnerability in Gmail that allowed attackers to steal session cookies and hijack users' email accounts. By sending a specially crafted email containing malicious code, attackers could execute arbitrary JavaScript in the context of the victim's Gmail session, leading to unauthorized access to sensitive information. ~ “ Be aware to cyber world”
