WHY CONVENTIONAL REPUTATION FEEDS MISS SOFTWARE SUPPLY CHAIN ATTACKS

Summary from the TLDR InfoSec newsletter

Conventional threat intelligence feeds and multi-engine scanners fail to detect most software supply chain attacks on day zero, exposing organizations to malicious package behavior for months after public disclosure. Research indicates that blind-spot rates for supply chain attacks in these reputation tools range from 70% to 90%. General-purpose security tools remain ineffective against these threats because they are designed to detect inbound perimeter probes rather than malicious package behavior.
