Null byte injection involves inserting a null character (e.g., %00) to terminate a string, often to bypass file extension checks or path validations, which is not what's described here.

IP fragmentation is a network layer technique where an IP packet is split into smaller fragments to bypass stateless firewalls or IDS, and is unrelated to SQL injection payload modification.

Character encoding involves representing characters in a different format (e.g., URL encoding, Unicode) to bypass filters, but the example given ('1'='1' vs 1=1) is a syntactical change, not merely an encoding change.

The technique described involves changing the characters in an SQL injection payload (e.g., from 'or 1=1' to 'or '1'='1') to evade detection systems that rely on predefined signatures. This is a common evasion technique called 'variation' or 'obfuscation' where the attacker modifies the attack signature while maintaining its functionality to bypass security controls like Web Application Firewalls (WAFs) or intrusion detection systems.
