Infostealers ULP Data Is Burning Out SOC Teams and Killing Automation

The issue described revolves around the systemic vulnerability in threat intelligence feeds used by enterprises for credential monitoring and automated response mechanisms. The core problem lies in how raw User Logon Pass-through (ULP) data is processed and disseminated through the intelligence supply chain, leading to operational fatigue and false positives that can severely disrupt business operations.

Key Points:

1. Raw ULP Data Vulnerability:

   • Raw ULP data lacks context and metadata necessary for verifying a genuine compromise.
   • Aggregators often strip out critical provenance information (like IP telemetry, hardware IDs, system.txt files) to reduce storage costs, turning high-fidelity intelligence into noise.

2. Lazy Aggregation Practices:

   • "Lazy aggregators" receive full logs but discard metadata, passing only ULP strings downstream.
   • This practice introduces systemic risk by propagating unverified data across multiple layers of the supply chain.

3. Operational Fatigue and False Positives:

   • When poisoned ULP lists trigger automated response playbooks (e.g., SOAR), they generate massive ticket storms, locking out legitimate users from SSO environments.
   • This operational fatigue leads to significant disruptions in business continuity, affecting multiple departments such as
