Inclusion of Undocumented Features or Chicken Bits

Manufacturers sometimes embed undocumented switches, known as 'chicken bits,' to help engineers quickly disable problematic features during debugging and testing. While useful for development, these hidden controls can bypass critical security mechanisms if left accessible in production hardware. Attackers can reverse-engineer these undocumented interfaces to gain unauthorized access or elevate privileges. Since these features are not documented for end users, they often lack proper security safeguards, creating a persistent backdoor that undermines the device's intended security posture.
