During an internal penetration test you attempt to hijack an active Telnet session, but the in-line IDS drops packets whose sizes or TCP flag patterns match its signatures. To conceal your injected commands, you need a tool that proxies the connection and automatically breaks, reorders, and flags TCP fragments to evade inspection. Which utility fits this role?
fragroute operates as a transparent proxy between the attacker and the target host, rewriting outbound traffic on the fly. Its rule set lets you segment payloads into small chunks (for example 8, 16, or 32 bytes), reorder segments, set unusual TCP flags, and add artificial delays-techniques that can slip packets past both signature- and anomaly-based IDS/IPS or stateful firewalls. Ettercap and Cain & Abel can sniff or alter traffic but do not provide automated fragmentation/evasion logic, while Netcat simply forwards data without modifying packet structure.
