# Drive-By Download

An attack where malware is automatically downloaded and potentially executed when a user visits a compromised or malicious website, typically by exploiting a browser or plugin vulnerability. In TLCTC: maps to `#3 Exploiting Client` (browser vulnerability exploited) → `#7 Malware` (payload execution). If the user was lured to the site via social engineering, the full sequence is `#9 → #3 → #7`.

**Reference:** V1.9.1 §F (Edge-Case Resolution)
