What is ARP Spoofing? ARP Spoofing is a network attack technique that exploits structural vulnerabilities in the ARP (Address Resolution Protocol), which was standardized through RFC 826 by the IETF in 1982. The attacker sends falsified ARP messages to the network to manipulate the victim’s ARP cache table and intercept or modify normal communication flows. This attack is a form of Man-in-the-Middle (MITM) attack. It is possible because the ARP protocol prioritized efficiency over security during its design phase and did not include authentication or integrity verification mechanisms. ...

What is a Reverse Shell? A reverse shell is an attack technique that reverses the direction of typical remote access connections. The compromised target system initiates a connection to the attacker’s system, allowing the attacker to access the target’s shell. This remote command execution mechanism exploits a fundamental characteristic of modern network security architectures. Most networks implement “block inbound, allow outbound” firewall policies, and reverse shells bypass this by having the target initiate the connection. This enables attackers to access systems behind restrictive network environments, NAT configurations, and corporate firewalls. ...
