Session Splicing and IDS Evasion Techniques

Session Splicing Attacks

• A session splicing attack is a type of evasion technique used to bypass IDS (Intrusion Detection System) by splitting a malicious packet into multiple碎 packets, making it difficult for IDS to detect.

Tools for Session Splicing

• Tcpclip is a tool that can be used to perform session splicing attacks.

Goals of Session Splicing

• The idea behind session splicing is to evade detection by IDS by splitting a malicious packet into multiple fragments, which are then reassembled at the target system.

IDS Limitations

• Many IDS stop reassembling and handling a stream after a certain period, usually due to performance or resource constraints.

Evasion Techniques

• After a successful splicing attack, the IDS will not log the attack, as it is unable to reassemble the fragmented packets and detect the malicious activity.
