USB‑C Cables Mis‑represent Specs – Free Mac App Reveals Supply‑Chain Gaps
What Happened — Using the open‑source macOS app WhatCable, ZDNet tested a variety of USB‑C cables and found several that advertised higher power‑delivery or data‑rate capabilities than they actually supported. The discrepancy is invisible to the naked eye, making it easy for end‑users and organizations to purchase non‑compliant hardware.
Why It Matters for Compliance & Audit Readiness
- Mis‑labeled cables constitute a supply‑chain control gap that can undermine the System and Organization Controls (SOC 2) Vendor Management criteria (CC6.1, CC6.2).
- Continuous evidence of vendor‑product validation (e.g., periodic hardware spec verification) is required to demonstrate due diligence during audits.
- The Verisq Vendor Risk capability can automatically ingest test results from tools like WhatCable and map them to SOC 2 vendor‑management controls, providing real‑time audit evidence.
Who Is Affected – All industries that rely on USB‑C for power or data transfer, notably technology, finance, healthcare, and remote‑work environments.
Recommended Actions
- Incorporate hardware‑spec verification into your vendor‑risk onboarding checklist.
- Log verification results in a centralized compliance repository to satisfy SOC 2 evidence requirements.
- Periodically re‑test critical cables, especially after bulk purchases or vendor changes.

Technical Notes – The discrepancy stems from manufacturers labeling cables for up to 100 W/40 Gbps without meeting the USB‑PD or Thunderbolt specifications. No CVE is involved; the risk is a misconfiguration of product claims.
