Cybersecurity researchers have uncovered alarming details about a Chinese state-sponsored hacking group leveraging a powerful backdoor tool, GHOSTSPIDER Malware, to infiltrate telecom networks globally.
These hackers, linked to Earth Estries, also known as Salt Typhoon, have targeted over 20 organizations across 12+ countries, leaving a trail of compromised data and sophisticated espionage in their wake.
Key Takeaway to GHOSTSPIDER Malware and Chinese Sophisticated Espionage Campaigns:
- Earth Estries, using GHOSTSPIDER Malware, exemplifies the rising threat of cyberattacks on critical industries like telecommunications, with global implications for security and privacy.
The Global Reach of GHOSTSPIDER Malware
According to cybersecurity firm Trend Micro, Chinese hackers target telecoms worldwide through meticulously organized campaigns. Earth Estries, active since at least 2020, deploys an arsenal of advanced malware, including GHOSTSPIDER, to gain long-term access to their targets.
Victims span multiple sectors, from telecommunications and technology to government and transportation, with affected countries including the U.S., India, Malaysia, South Africa, and Thailand.
In one striking example, Earth Estries infiltrated several U.S.-based telecom giants, accessing sensitive customer call records. Among the targets were high-profile individuals, such as politicians and government officials. This campaign highlights the growing risk to both public and private sectors.
How GHOSTSPIDER Malware Operates
GHOSTSPIDER Malware is a modular and highly adaptable tool that attackers use to infiltrate systems. It communicates with command-and-control (C&C) servers using encrypted protocols like TLS, enabling hackers to send additional malicious modules as needed.
The malware typically enters systems through known vulnerabilities in widely used software. For instance, attackers exploited flaws in Microsoft Exchange (ProxyLogon) and Ivanti Connect Secure to gain access.
Once inside, GHOSTSPIDER allows hackers to establish control, monitor activity, and exfiltrate sensitive data over months or even years.
Key Malware Features
| Feature | Function |
|---|---|
| Multi-modular design | Enables attackers to add or update tools flexibly. |
| Custom communication | Uses encrypted channels for stealthy operations. |
| Persistent access | Maintains long-term presence in victim networks. |
Earth Estries: A Sophisticated Threat Actor
Trend Micro describes Earth Estries as an advanced persistent threat (APT) with a clear division of labor.
They operate with precision, deploying unique malware families like MASOL RAT, Demodex, and Deed RAT. Their campaigns show clear signs of collaboration among different teams managing distinct parts of the operation.
For example, researchers found that some teams shared large lists of fake e-commerce sites for scams, while others maintained separate infrastructures for cyber espionage. This complex structure makes detection and prevention incredibly challenging.
Why Telecoms Are a Prime Target
Telecommunications networks are often the backbone of critical infrastructure. Hackers like Earth Estries exploit these systems to monitor communications, gather intelligence, and launch secondary attacks.
By using GHOSTSPIDER Malware, these attackers can intercept sensitive information, including call logs and user credentials, to further their cyber espionage goals.
This pattern mirrors previous attacks by other Chinese groups, such as Volt Typhoon, which targeted U.S. infrastructure to potentially enable destructive actions in future conflicts.
Lessons from Previous Cyberattacks
A similar attack occurred in 2021 when another Chinese group exploited vulnerabilities in Pulse Secure VPNs to infiltrate U.S. government networks.
The attackers gained administrative access, allowing them to steal sensitive data over several months. This shows the persistent nature of Chinese state-sponsored hacking campaigns.
Protecting Against GHOSTSPIDER Malware
Organizations can take the following steps to safeguard against GHOSTSPIDER Malware and other advanced threats:
- Patch Known Vulnerabilities: Regularly update systems to address security flaws.
- Monitor Network Traffic: Use tools to detect unusual activity.
- Enhance Employee Awareness: Train staff to recognize phishing attempts.
- Deploy Endpoint Protection: Use appropriate software for advanced threat defense.
- Limit Internet Exposure: Reduce the attack surface by securing public-facing servers.
Chinese hackers’ use of GHOSTSPIDER Malware reveals the growing sophistication of cyber threats targeting critical industries. By staying vigilant and adopting proactive security measures, organizations can better defend against these evolving risks.
About Earth Estries
Earth Estries, also known as Salt Typhoon, is a Chinese state-sponsored hacking group active since at least 2020. The group specializes in cyber espionage, targeting telecoms, government agencies, and critical industries worldwide. Their sophisticated methods and use of tools like GHOSTSPIDER Malware have positioned them as one of the most dangerous APTs operating today.
