Summary
The US, UK, and Australia have initiated a joint project to develop underwater drone technology aimed at protecting critical subsea cables, which are being cut at an unprecedented rate. Australian Defence Minister Richard Marles emphasized the vulnerability of undersea internet cables, stating that 99% of Australia’s internet traffic relies on just 15 cables. Over the past 18 months, there have been multiple incidents of cable severance, with five attributed to China in the Taiwan Strait and three linked to Russia in the Baltic Sea. Marles warned that these incidents could indicate nations testing response times and political will. The initiative is part of the AUKUS alliance's second pillar, with plans to deploy advanced multi-mission underwater vehicles by 2027. The project aims to enhance maritime security and deter potential threats to vital infrastructure. Key Points: • AUKUS alliance launches underwater drone program to protect subsea cables. • Record rates of cable severance have been reported, with incidents linked to China and Russia. • 99% of Australia's internet traffic is dependent on just 15 subsea cables, highlighting vulnerability.
Detailed Analysis
**Impact** Critical subsea internet cables are being targeted, affecting global communications and infrastructure. Australia is particularly vulnerable, with 99% of its internet traffic relying on just 15 subsea cables. Attacks have occurred in the Taiwan Strait (five incidents attributed to China) and the Baltic Sea (three incidents attributed to Russia), impacting sectors including finance, healthcare, communications, and intelligence partnerships. The disruption risks operational outages and potential data interception or loss. **Technical Details** The attack vector involves physical sabotage of undersea cables, potentially using “shadow fleet” vessels operating in grey zones between commercial and state maritime activities. No specific malware, CVEs, or digital intrusion methods were reported. The threat actors appear to be state-affiliated or state-tolerated, using uncrewed underwater vessels and covert maritime operations to sever cables. Indicators of compromise (IOCs) were not provided. **Recommended Response** Deploy and accelerate development of underwater drone technology equipped with advanced sensors and weapons systems to monitor and protect subsea cable infrastructure. Increase maritime domain awareness focused on shadow fleet vessel movements and suspicious activities near critical cable routes. Enhance international cooperation for transparency in maritime operations and invest in redundancy for subsea cable networks to mitigate single points of failure. Monitor for unusual maritime traffic patterns and physical disruptions near cable landing sites.
