Supply Chain Attacks: A New Era

Bruno Halltari and Caue Obici · OtterSec · 10 June 2024

LavaMoat defends JavaScript builds against malicious dependencies with per-package policy files, dependency-tree naming and scuttling of dangerous globals. The article reports two bypasses: a crafted multi-line source-map comment survives lavapack's comment stripping and escapes the generated wrapper, running code at bundle load; and document.execCommand creates a same-origin frame SnowJS does not hook, giving an unscuttled realm. Chained, they defeat the protection.
