Initial Access
The first stage of an intrusion: the technique an attacker uses to gain a foothold in a target environment, such as phishing, exploiting an internet-facing vulnerability, or using stolen credentials. MITRE ATT&CK catalogs initial access as its own tactic, and 'initial access brokers' sell footholds to other criminals.
