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.
