TSTT is phasing out its legacy copper networks by September 2024 due to persistent copper theft and vandalism, a global issue exacerbated by rising copper prices. The theft targets critical infrastructure like electrical substations, cellular towers, landlines, and railroads, causing service disruptions, financial losses, and operational vulnerabilities. While TSTT has migrated over 100,000 subscriptions to fiber or fixed wireless, the prolonged reliance on copper exposed the company to cyber-physical risks, including potential sabotage or exploitation of outdated infrastructure by malicious actors. The delayed 'Zero Copper' initiative (originally slated for 2021) highlights systemic vulnerabilities, where physical breaches of copper lines could enable cyber intrusions (e.g., eavesdropping, data interception, or network compromise). Though the article focuses on theft, the underlying risk of cyber attacks leveraging unsecured copper-based systems such as man-in-the-middle attacks or service hijacking poses threats to national communication resilience, customer data integrity, and critical utility operations. The migration mitigates these risks but underscores past exposure to high-impact breaches or attacks during the transition period.
