Summary - Reasons this attack is often successful.

Local Overrides for Testing: Developers and system administrators often use the hosts file to override DNS settings for testing purposes.

Performance and Caching: The hosts file is consulted before querying DNS servers. If a hostname is already listed in the hosts file, the system uses the IP address specified there without making a DNS query.

Network Isolation: In some environments, machines may be intentionally isolated from the broader network or specific DNS servers. In such cases, relying on local entries in the hosts file can provide a way to manage network configurations independently.

DNS Server Unavailability:If the DNS server is temporarily unavailable or experiencing issues, local entries in the hosts file can serve as a fallback, ensuring that critical services or applications can still function.

Preventing External Lookups:In some security or privacy-conscious scenarios, administrators may configure hosts files to prevent certain hosts from making external DNS queries. By mapping domains to local IP addresses, they can control where certain requests go.

Project Details

 /etc/hosts file is a simple text file used in Unix and Unix-like operating systems, including Linux. It maps IP addresses to hostnames, allowing you to manually specify the IP address for a given domain. This can be useful for various purposes, such as local development, testing, or overriding DNS entries.
