The ThreatList was a sample and threat-intelligence sharing system, hosted by AMTSO but available to approved participants both within and outside the AMTSO membership.

ThreatList was created to fill the gap left by the termination of the WildList, a long-standing cross-industry collaboration project used by many test labs in certification testing and more. Previous WildList reporters were invited to participate in ThreatList at its foundation, and the system was opened to new contributors. 

ThreatList was managed by AMTSO volunteers under the guidance of the ThreatList Oversight Board, also volunteers elected from among the ThreatList community. 

ThreatList was operated alongside but fully separated from AMTSO’s own sample-sharing system, the Real-Time Threat List (RTTL).

After trials and outreach through 2024-25, the project was halted with key features planned to be rolled into the main RTTL system.
