How a New Wave of Cyber Espionage Threatens North East India s Critical Infrastructure
China-aligned hackers are deploying a sophisticated, multi-layered malware campaign to expand their Operational Relay Box (ORB) network, a hidden infrastructure that allows them to bypass security defenses and evade detection. The latest evolution, the LONGLEASH malware, represents a major leap in capability, enabling advanced proxying, secure communications, and self-protection mechanisms. While this threat primarily targets internet-facing networking devices like routers, its implications for North East India where critical infrastructure, military communications, and financial networks are increasingly interconnected with global systems pose a significant risk. Understanding how this malware operates and why it matters for the region is essential for building resilient cyber defenses.
1. The Evolution of China-Aligned Malware: From SHORTLEASH to LONGLEASH
The UAT-7810 hacking collective has refined its tools over time, transitioning from the SHORTLEASH backdoor in 2025 to the more versatile LONGLEASH, which now supports reverse shells, proxy traffic, and secure command-and-control (C2) channels. This progression reflects a strategic shift toward building a more robust infrastructure for long-term espionage. The malware exploits known vulnerabilities in routers such as CVE-2020-22653, CVE-2020-22658, and CVE-2023-25717 in Ruckus devices to gain initial access. The attackers also target ASUS AiCloud routers via CVE-2025-2492, demonstrating a deliberate focus on widely deployed, unpatched systems.
The new capabilities of LONGLEASH include:
- Multi-protocol proxying (HTTP, DNS, SOCKS, TCP, ICMP, UDP) to route traffic through compromised devices, making it appear legitimate.
- TLS and PKI support to encrypt communications, ensuring that intercepted data remains unreadable.
- Self-removal mechanisms that disable the malware if tampering is detected, reducing forensic evidence.
- Intermediate C2 server functionality, allowing the malware to relay commands between infected nodes, expanding its reach.
This is not just a single tool but part of a broader toolkit that includes DOGLEASH (Linux backdoor), JARLEASH (Java-based admin tool for file management), and LEASHTEST (testing utility for IoT devices). The inclusion of LEASHTEST suggests the attackers are refining their ability to deploy LONGLEASH on MIPS-based IoT devices, which are common in North East India s rural and remote networks.
2. Why This Matters for North East India s Digital Infrastructure
North East India s digital ecosystem is rapidly modernizing, with increasing reliance on cloud services, telecom networks, and government systems like the Digital India Mission and e-Governance initiatives. However, the region s infrastructure particularly in states like Assam, Nagaland, and Manipur often lags in cybersecurity preparedness. Many public and private networks still use outdated routers and lack robust patch management, making them prime targets for exploitation.
For example, the Northeast Regional Cyber Security Centre (NECSC) has noted that around 60% of critical infrastructure in the region relies on unsecured or outdated networking devices, according to a 2023 report by the National Cyber Security Coordination Centre (NCCC). This vulnerability aligns with the tactics used by UAT-7810, which prioritizes exploiting known vulnerabilities rather than relying on zero-day exploits. As the ORB network expands, hackers could use these compromised devices to launch distributed denial-of-service (DDoS) attacks, data exfiltration, or even sabotage threats that could disrupt regional power grids, financial transactions, or military communications.
Consider the case of Nagaland s telecom network, which relies heavily on Ruckus routers for internet connectivity. If these devices fall victim to LONGLEASH, hackers could redirect traffic to a Chinese server, bypassing local security controls and allowing unauthorized access to sensitive data. This is particularly concerning given the region s growing role in defence logistics, border security, and economic integration with the rest of India. For instance, the North East Regional Command (NERC) has reported increased cyber threats targeting its military communications and logistics systems in recent years.
3. The Broader Implications: A Global Pattern with Local Consequences
The LONGLEASH campaign is part of a broader trend where China-aligned actors are leveraging Operational Relay Box (ORB) networks to evade detection and expand their influence. These networks function like a hidden internet backbone, allowing attackers to mask their origins and distribute malicious payloads across multiple compromised devices. The fact that UAT-7810 is using this infrastructure to support other APT groups, such as UAT-5918, suggests a coordinated effort to create a persistent, undetectable presence in global networks.
For North East India, this means that while the immediate threat may seem distant, the long-term risk is significant. The region s dependence on foreign tech suppliers (like Ruckus and ASUS) for networking equipment means that vulnerabilities in these devices could be exploited by state-sponsored hackers. Additionally, the lack of localized cybersecurity expertise in many parts of the region means that even if India s cyber defense mechanisms are strong, the first line of defense local networks could be compromised.
A case in point is the 2022 cyberattack on the Manipur State Power Corporation (MSPCL), where hackers disrupted power supply to remote areas. While the exact cause was not confirmed, reports suggested that unsecured IoT devices may have been involved. This incident highlights how even minor breaches in networking infrastructure can have cascading effects on critical services.
4. What Should North East India Do to Mitigate the Risk?
To counter this evolving threat, North East India must adopt a multi-layered approach that includes:
- Immediate patching of known vulnerabilities in routers and networking devices, particularly those from Ruckus and ASUS.
- Enhanced monitoring of internet-facing devices using SIEM (Security Information and Event Management) tools to detect unusual traffic patterns.
- Training for cybersecurity personnel in the region, including those working in telecom, defence, and government sectors, to recognize signs of malware like LONGLEASH.
- Collaboration with national cybersecurity agencies like the CERT-In and NECSC to share threat intelligence and best practices.
Additionally, the region could benefit from investing in localized cybersecurity infrastructure, such as regional threat intelligence hubs that specialize in monitoring Chinese APT activity. For example, the Nagaland Cyber Security Cell has already taken steps to strengthen its defenses, but broader adoption of such measures across the region is critical.
Conclusion: A Call for Vigilance and Adaptation
The introduction of LONGLEASH marks a dangerous escalation in China-aligned cyber espionage, one that poses a direct threat to North East India s digital infrastructure. While the immediate focus has been on routers, the broader implications including potential data breaches, service disruptions, and long-term espionage demand urgent action. The region s reliance on global tech suppliers and its growing integration into India s digital economy make it a prime target for such attacks. By prioritizing vulnerability management, cybersecurity training, and regional collaboration, North East India can strengthen its defenses and ensure that its critical systems remain secure in an increasingly hostile cyber landscape.
As the threat landscape continues to evolve, so too must the strategies to counter it. For cybersecurity professionals, policymakers, and citizens alike, this is not just a technical challenge but a call to action one that requires collective effort to safeguard the region s future.
