Final answer:
A cross-site scripting (XSS) attack is a security exploit where attackers inject malicious scripts into web content, which can steal credentials or redirect users to malicious sites to install malware. It's crucial to be aware of and protect against these sophisticated cyber threats.
Step-by-step explanation:
A cross-site scripting (XSS) attack is a type of security vulnerability typically found in web applications. XSS enables attackers to inject malicious scripts into content that appears to be from a trusted source. When other users load the affected pages, the malicious script then executes, which can lead to a number of malicious activities. One common objective of XSS attacks is to steal credentials, such as usernames and passwords. Attackers can also redirect users to websites that exploit browser vulnerabilities to install malware, spyware, or ransomware.
Hackers use a variety of methods to compromise security, including luring individuals to click on malicious links and deceitfully obtaining personal information. The success of XSS attacks often relies on unsuspecting users trusting the injected script because it appears to come from a legitimate source. Awareness and proactive security measures are essential for protecting against these sophisticated cyber threats.
