A Silent Cyberwar: Unmasking Salt

In the modern age of cyberwarfare, silent battles are being fought behind firewalls and encrypted tunnels. One of the most disturbing recent revelations is the sweeping campaign launched by a Chinese state-backed cyber-espionage group dubbed Salt Typhoon. These hackers have infiltrated major telecommunications networks not just in the United States, but across the globe. The breaches are not only technical violations — they mark a serious intrusion into sensitive governmental, corporate, and personal data systems.

The FBI, in collaboration with CISA and other U.S. federal entities, has now gone public in its hunt for information about this elusive group. Offering a reward of up to $10 million, the United States is calling on global citizens and cybersecurity communities to help unmask those responsible. As investigations deepen, Salt Typhoon’s network of tactics and tools has been exposed, revealing a coordinated strategy of exploitation, espionage, and surveillance that dates back years.

This article dives into the scope of the breach, the hackers’ tactics, and what it all means for global cybersecurity — especially as the digital lines between private infrastructure and national security continue to blur.

Inside the Cyber Campaign: Key Developments and Findings

  • The FBI has issued a public call for help in identifying Salt Typhoon, a Chinese hacking group involved in the infiltration of telecom networks across the U.S. and dozens of other countries.
  • In October, the FBI and CISA confirmed the group had breached several major American telecommunications providers, including AT&T, Verizon, Charter Communications, and others.
  • Notably, the attackers accessed U.S. law enforcement’s wiretapping systems, extracting sensitive data from a limited number of U.S. government officials.
  • The campaign, according to the FBI, involved stealing call logs, intercepting private communications, and copying data linked to law enforcement wiretap requests.
  • The Department of Treasury has sanctioned Sichuan Juxinhe Network Technology, a Chinese firm linked directly to these breaches.
  • The Department of State’s Rewards for Justice (RFJ) program is offering a $10 million reward for actionable intelligence on Salt Typhoon or its members.
  • The group is also known by aliases like Ghost Emperor, FamousSparrow, Earth Estries, and UNC2286 — showing a history of rebranding and complex attribution.
  • Active since at least 2019, Salt Typhoon continues to breach networks, most recently in late 2024 and early 2025, exploiting unpatched Cisco IOS XE vulnerabilities.

– The latest targets include:

– A U.S. internet service provider

  • A U.S.-based affiliate of a U.K. telecom company
  • Telecom providers in Italy, South Africa, and Thailand
  • Cisco has reported the use of a custom malware tool, JumbledPath, used to monitor network traffic and exfiltrate sensitive data covertly.
  • In response, U.S. officials are considering a ban on TP-Link routers, and possibly a shutdown of China Telecom’s remaining operations in the country.

What Undercode Say:

Salt Typhoon’s digital incursion is a watershed moment in global cybersecurity, illustrating how deep-rooted and systemic cyber espionage has become. The breaches didn’t just involve unauthorized access — they penetrated the heart of law enforcement’s surveillance tools and compromised government-level confidentiality.

This campaign is sophisticated. Rather than relying on brute-force attacks or noisy malware, Salt Typhoon exploited low-profile vulnerabilities in networking hardware like Cisco IOS XE — flaws that are easily overlooked in massive telecom infrastructures. These were not amateur exploits. They were methodically executed, and the targeting suggests a deeper agenda: mapping communication flows, tracking officials, and quietly intercepting intelligence-grade data.

The decision by the FBI to publicly solicit help — and attach a $10 million reward — underscores the gravity of the situation. Such announcements are rare, and when they occur, they typically point to cyber actors of significant geopolitical concern. This is not just about data theft; it’s about state-level intrusion into U.S. sovereign communication networks.

The involvement of a Chinese cybersecurity firm, Sichuan Juxinhe Network Technology, adds another layer to the story — hinting at private-public collaboration in cyberwarfare. While attribution in cybercrime is notoriously complex, the repeated identification of Salt Typhoon through their malware footprints, TTPs (tactics, techniques, and procedures), and digital infrastructure points to a state-supported operation.

Another concerning dimension is how Salt Typhoon continues to operate even after being exposed multiple times. This shows resilience and perhaps even protection from repercussions within their operating country. Despite global exposure, sanctions, and widespread media coverage, their campaigns continue — evolving with new methods and targeting fresh victims.

In terms of impact, the breaches highlight a vulnerability in global telecom infrastructure that many nations are unprepared for. Legacy systems, unpatched devices, and reliance on foreign-made hardware make telecoms a soft target for nation-state actors.

Furthermore, the potential banning of TP-Link routers and China Telecom operations indicates that these attacks are shifting from purely cyber responses to policy-level countermeasures. This suggests that the U.S. is beginning to treat cyber incursions as acts that warrant real-world consequences, such as trade restrictions and diplomatic pushback.

Looking forward, this saga may serve as a catalyst for global telecom providers to reassess their network security, prioritize timely patching of known vulnerabilities, and reduce dependency on hardware from nations seen as geopolitical adversaries.

If nothing else, Salt Typhoon has exposed just how fragile the illusion of secure communications really is in our interconnected world.

Fact Checker Results:

  • The breaches and hacker group names have been confirmed by FBI, CISA, and Cisco.
  • Public sanctions have been placed on related Chinese firms by the U.S. Treasury.
  • The RFJ program does list a $10M reward for information leading to the identification of these cyber actors.
