Difficulty: premium
Definition
An Advanced Persistent Threat is a well-resourced, targeted attacker that quietly gains access to an environment and maintains long-term, covert presence to steal information or disrupt operations.
Examples
- A tailored spear-phish gets one foothold; over weeks the intruder steals credentials, learns the network, and slowly exfiltrates design files.
- A compromised software update at a supplier installs a backdoor; the attacker uses the trusted channel to reach many customers.

APT actors don’t rush. They pick a target, study it, and enter with as little noise as possible. The word advanced refers to planning, tooling, and resources; persistent means they work to keep access for months; threat reminds us the goal is real harm—espionage, theft, or disruption.
