Q: What is network hijacking, specifically by ISPs?
A: Network hijacking occurs when an attacker or a network element (like an ISP) intercepts a user's HTTP request and sends a crafted response. This allows them to insert unwanted content, such as ads or malware, into the user's browsing session, manipulate web pages, and potentially steal sensitive information.
Defences:
- Use HTTPS (SSL/TLS) to encrypt all communication.
- Regularly update your OS and browser.
- Use a trusted VPN service.
- Only download software from official and verified sources.
