China's Ghost in Asian Telecoms: Multi-Year Cyber Espionage Campaign Exposed

A sprawling cyber espionage operation tied to Chinese state-sponsored actors has systematically infiltrated telecommunications networks across Asia for years, security researchers have revealed. The campaign, operating under the names 'Salt Typhoon' and associated with the LightBasin hacking collective, represents one of the most persistent threats to global telecom infrastructure in recent memory.

Technical analysis indicates the attackers employed a multi-layered approach, combining custom malware with exploitation of known vulnerabilities in telecom-specific systems. Their primary targets included subscriber information databases, call detail records, and critical network infrastructure components. This access would provide intelligence agencies with unprecedented visibility into communications patterns across the region.

The operation's discovery comes amid heightened concerns about Chinese cyber activities following the breach of the US Treasury Department, which officials described as a 'major incident.' Similarities in tactics suggest possible coordination between different Chinese threat groups targeting government and commercial telecommunications networks.

Security Affairs reports that the intrusions were so comprehensive that US agencies cautioned employees about potential compromises through hacked telecom providers. The attackers demonstrated deep knowledge of telecom protocols, including SS7 and 5G networking standards, allowing them to move laterally through networks with alarming efficiency.

CrowdStrike researchers, who first identified LightBasin's activities, noted the group's unique focus on telecommunications. 'They're not after financial data or intellectual property in the traditional sense,' explained one analyst. 'They're building a map of regional communications that could be invaluable for both intelligence gathering and potential network disruption during geopolitical tensions.'

The campaign's longevity - active since at least 2019 according to The Hacker News - suggests either exceptional operational security or systemic weaknesses in telecom network defenses. Many victims reportedly remained compromised for years before detection, with some breaches only discovered through unrelated security audits.

As governments and corporations reassess their telecom security postures, the incident underscores the growing convergence of cybersecurity and national security concerns in an increasingly connected world. The revelations are likely to accelerate existing efforts to secure critical communications infrastructure against state-sponsored threats.
