How it's used
This term carries a strong sense of betrayal and is typically used in the context of organizations, groups, or teams. It implies a deeper level of malice than just being a spy, as it specifically highlights the violation of trust from someone who was supposed to be on the same side. While often used in dramatic or serious situations, it can also be used hyperbolically in casual settings to describe someone who spoils a surprise or shares private group information.

Common mistake
Do not confuse this with 卧底, which is a neutral or even positive term for an undercover agent or police officer. 內奸 is strictly negative and implies treachery, whereas 卧底 can be a professional role.
