AN1863: Analytic 1863
Use verification of distributed binaries through hash checking or other integrity checking mechanisms. Scan downloads for malicious signatures.
Analyst context for executives and security teams
This analytic is about verifying downloaded or distributed binaries before they are used, using hashes, integrity checks, and malware signature scanning. For ICS environments, the practical value is reducing the chance that untrusted or tampered software enters operational technology workflows, maintenance processes, or engineering systems. Because the ATT&CK object provides no platform, tactic, or relationship context, it should be treated as a control-validation analytic rather than a complete detection use case.
Executive priority
Leaders should use this as a prompt to ask whether software, firmware, tools, and update packages used in ICS-related environments are verified before deployment. The business issue is assurance: can the organization prove that binaries were checked for integrity and malicious content before they touched operational systems? This supports resilience, audit evidence, incident readiness, and risk-based prioritization of software supply-chain controls, especially where downtime or unsafe operational changes would be material.
Technical view
SOC, IR, and OT security teams should validate whether there is a documented and observable process for hash verification, integrity checking, and malware scanning of downloaded or distributed binaries. Since no official detection logic, platforms, or tactics are supplied, teams should not assume SIEM coverage exists. Instead, confirm where binary downloads occur, where hashes are obtained and stored, how integrity mismatches are handled, and whether scan results are logged in a way analysts can review during investigations.
Likely telemetry
- File download logs or transfer records for binaries and packages
- Hash calculation or file integrity verification records
- Malware or signature scan results for downloaded files
- Change management or deployment records showing approval before use
- Asset, engineering workstation, or server logs where binaries are staged or distributed
Detection direction
- Validate that hash and integrity checks generate reviewable evidence, not just manual checklist activity.
- Tune monitoring to identify binaries introduced without an associated verification record where local logging supports it.
- Confirm that malware scan failures, skipped scans, or integrity mismatches create alerts or workflow stops appropriate to the environment.
- Account for false positives from legitimate vendor updates, internally built tools, or files whose hashes change between versions.
- Because ATT&CK provides no platform or tactic context for this analytic, map detection coverage to local ICS software distribution paths rather than assuming broad applicability.
Mitigation priorities
- Establish a required verification process for distributed binaries using trusted hashes or other integrity mechanisms.
- Scan downloads for malicious signatures before use in ICS-related workflows.
- Retain verification and scan evidence for incident response and compliance review.
- Define exception handling for missing hashes, failed checks, or urgent operational needs.
- Integrate binary verification with change management so deployment approval depends on successful validation.
Analyst notes and limits
This is an ICS ATT&CK detection analytic identified as AN1863. The official description is concise and focuses on binary integrity verification and malicious signature scanning. No official detection text, platforms, tactics, labels, aliases, or relationships were supplied, so the take is framed around control validation and evidence collection rather than a specific behavioral detection.
Coverage and priority depend on the local ICS environment, software distribution model, available logging, and operational change process. The supplied ATT&CK fields do not identify affected platforms, related techniques, adversaries, active exploitation, or expected log sources, so those should not be inferred without local evidence.
Analytic 1863
Use verification of distributed binaries through hash checking or other integrity checking mechanisms. Scan downloads for malicious signatures.
How security teams should use this page
