A major cyber-attack, linked to China, has allowed hackers to spy on U.S. officials and politicians by gaining access to their cellphone communications. The hacking group, known as Salt Typhoon, carried out a sophisticated attack that went undetected for months, compromising the private data of thousands of Americans. This attack highlights the growing power of cyber-espionage and how vulnerable even the most secure communications can be.
Unseen Access to U.S. Telecommunications
Hackers working for China’s government infiltrated U.S. telecommunications networks over a period of eight months or longer. They focused on the mobile phone lines used by senior government officials, including those working in national security and politics. These hackers didn’t just target one or two people, but rather carefully selected a group of high-profile individuals, likely including those close to top politicians such as former President Donald Trump and Vice President Kamala Harris.
The hackers were able to access personal information, including phone call logs, unencrypted text messages, and, in some cases, even voice recordings. This level of access meant that anyone who communicated with these U.S. officials—whether through calls, texts, or other means—could have also had their private information exposed. While the hackers didn’t appear to target everyone, their reach was wide, potentially involving thousands of individuals connected to U.S. officials.
The Method: Deep Intrusion into U.S. Networks and Telecom Systems
The attackers were able to gain access to U.S. networks by exploiting weaknesses in the telecommunications infrastructure. They did this in stages, starting with a core layer of network equipment and then moving deeper into the system. By using these methods, the hackers could learn how the U.S. communications system operates and remain undetected for a long time.
One of the most troubling aspects of the attack was the hackers’ ability to compromise the systems of telecom companies, including AT&T and Verizon. These are two of the largest mobile carriers in the U.S., and many of their customers, including U.S. officials, were at risk. The attackers even targeted systems that telecom companies use to comply with court-ordered surveillance. This suggests that the hackers may have been able to monitor sensitive U.S. investigations into Chinese spies and other national security matters.

The hackers didn’t just focus on the U.S. They also infiltrated telecom systems in other countries that are close allies of the United States. The full extent of the attack’s reach is still not clear, but experts believe more countries and victims will be identified as the investigation continues.
Bold Tactics and Continued Access to U.S. Officials’ Data
The hackers were able to keep their access to the compromised systems even after their actions were detected. They used advanced techniques to re-enter systems that had been patched up after the breach. This shows how persistent and determined they were, continuing to gather sensitive information even after their cover had been blown.
The group behind the Salt Typhoon attacks is believed to be working for China’s Ministry of State Security (MSS), an agency responsible for foreign intelligence gathering. U.S. intelligence officials have confirmed that the attackers were highly skilled, using a range of tactics and tools to stay in the system for as long as possible. The hackers even managed to gather some audio recordings of their targets, though it’s not clear whether these were voice memos or actual phone calls.
Despite the scale of the breach, the full impact of this hack is still being investigated. U.S. security officials are especially concerned about how China might use the stolen data. With the ability to spy on U.S. officials and their contacts, the attackers could gather valuable intelligence about the U.S. government’s decision-making processes, spy networks, and much more.
The Salt Typhoon group is not new to cyber-espionage. Previously, they were linked to several high-profile hacks, including a major breach of Microsoft’s email software in 2021. Their history of attacks on countries like France, the U.K., Israel, and others shows how widespread and sophisticated their operations are.
This hack is one of the most serious cyber-attacks on U.S. officials in recent years, raising alarms about the vulnerability of modern communications systems. The fact that such a large-scale espionage operation could go undetected for so long shows just how advanced China’s cyber-espionage capabilities have become.
