Protection Against Modern Attack Vectors

DNS hijacking attacks redirect users to malicious servers by compromising DNS responses. While HTTPS cannot prevent the initial redirection, it prevents attackers from successfully impersonating the legitimate site. Certificate validation fails when browsers connect to attackers' servers, warning users of the deception. This protection proves crucial as DNS infrastructure attacks become more common and sophisticated.

JavaScript injection represents a particularly dangerous attack vector on HTTP connections. Attackers can inject malicious scripts that steal data, redirect users, or exploit browser vulnerabilities. These scripts run with the same privileges as legitimate site code, accessing cookies, form data, and user inputs. HTTPS prevents injection during transmission, though sites must still protect against stored XSS and other application-level vulnerabilities.

Cryptocurrency mining malware has become a popular attack vector, with injected scripts using visitors' computing power for mining operations. These attacks slow down user devices, increase power consumption, and degrade user experience. While not directly stealing data, they represent a form of resource theft that damages user trust. HTTPS prevents the injection of mining scripts during transmission, protecting users from this parasitic behavior.

Ad injection and tracking represent both security and privacy concerns. ISPs and network operators have economic incentives to inject advertisements or tracking scripts into HTTP traffic. These injections can introduce vulnerabilities, slow page loads, and violate user privacy. Some injected ads have contained malware or redirected users to malicious sites. HTTPS removes the ability to monetize user traffic through injection, protecting both security and user experience.
