4. MITIGATIONS
ATI has created a patch which adds additional security features to the command packets sent over the radio. ATI is testing this patch, and it will be available upon request. Many systems are engineered to meet specific user needs and users need to make sure any upgrades are appropriate for their systems.
ATI recommends that, where feasible, simple voice radios be replaced with digital P-25 (APCO) radios, which provide highly secure encrypted links.
NCCIC reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
NCCIC also provides a section for control systems security recommended practices on the ICS-CERT web page. Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
Additional mitigation guidance and recommended practices are publicly available in the ICS‑CERT Technical Information Paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies, that is available for download from the ICS-CERT website.
Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to NCCIC for tracking and correlation against other incidents.
No known public exploits specifically target these vulnerabilities. High skill level is needed to exploit.
