Adversaries are turning the tools businesses trust into delivery mechanisms for malicious activity. Cisco Talos observed abuse of more than 25 legitimate platforms over the past year, exploiting the built-in trust of collaboration, file-sharing, payment and other services to reach their targets.

Editorial Analysis

Why it matters

Enterprises approving SaaS platforms at the firewall level inadvertently whitelist attacker delivery paths; this trend demands a shift from domain-based trust to content-based verification.

What to do

Implement content-inspection and sandboxing for files received through trusted SaaS platforms, regardless of domain reputation.

Board brief

Attackers are hijacking the business tools employees already trust for everyday work, requiring a fundamental shift from perimeter-based to content-based security.
