Huawei and Chinese Surveillance

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2025/11/huawei-and-chinese-surveillance.html

This quote is from House of Huawei: The Secret History of China’s Most Powerful Company.

“Long before anyone had heard of Ren Zhengfei or Huawei, Wan Runnan had been China’s star entrepreneur in the 1980s, with his company, the Stone Group, touted as “China’s IBM.” Wan had believed that economic change could lead to political change. He had thrown his support behind the pro-democracy protesters in 1989. As a result, he had to flee to France, with an arrest warrant hanging over his head. He was never able to return home. Now, decades later and in failing health in Paris, Wan recalled something that had happened one day in the late 1980s, when he was still living in Beijing.

Local officials had invited him to dinner.

This was unusual. He was usually the one to invite officials to dine, so as to curry favor with the show of hospitality. Over the meal, the officials told Wan that the Ministry of State Security was going to send agents to work undercover at his company in positions dealing with international relations. The officials cast the move to embed these minders as an act of protection for Wan and the company’s other executives, a security measure that would keep them from stumbling into unseen risks in their dealings with foreigners. “You have a lot of international business, which raises security issues for you. There are situations that you don’t understand,” Wan recalled the officials telling him. “They said, ‘We are sending some people over. You can just treat them like regular employees.’”

Wan said he knew that around this time, state intelligence also contacted other tech companies in Beijing with the same request. He couldn’t say what the situation was for Huawei, which was still a little startup far to the south in Shenzhen, not yet on anyone’s radar. But Wan said he didn’t believe that Huawei would have been able to escape similar demands. “That is a certainty,” he said.

“Telecommunications is an industry that has to do with keeping control of a nation’s lifeline…and actually in any system of communications, there’s a back-end platform that could be used for eavesdropping.”

It was a rare moment of an executive lifting the cone of silence surrounding the MSS’s relationship with China’s high-tech industry. It was rare, in fact, in any country. Around the world, such spying operations rank among governments’ closest-held secrets. When Edward Snowden had exposed the NSA’s operations abroad, he’d ended up in exile in Russia. Wan, too, might have risked arrest had he still been living in China.

Here are two book reviews.

Scam USPS and E-Z Pass Texts and Websites

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2025/11/scam-usps-and-e-z-pass-texts-and-websites.html

Google has filed a complaint in court that details the scam:

In a complaint filed Wednesday, the tech giant accused “a cybercriminal group in China” of selling “phishing for dummies” kits. The kits help unsavvy fraudsters easily “execute a large-scale phishing campaign,” tricking hordes of unsuspecting people into “disclosing sensitive information like passwords, credit card numbers, or banking information, often by impersonating well-known brands, government agencies, or even people the victim knows.”

These branded “Lighthouse” kits offer two versions of software, depending on whether bad actors want to launch SMS and e-commerce scams. “Members may subscribe to weekly, monthly, seasonal, annual, or permanent licenses,” Google alleged. Kits include “hundreds of templates for fake websites, domain set-up tools for those fake websites, and other features designed to dupe victims into believing they are entering sensitive information on a legitimate website.”

Google’s filing said the scams often begin with a text claiming that a toll fee is overdue or a small fee must be paid to redeliver a package. Other times they appear as ads—­sometimes even Google ads, until Google detected and suspended accounts—­luring victims by mimicking popular brands. Anyone who clicks will be redirected to a website to input sensitive information; the sites often claim to accept payments from trusted wallets like Google Pay.

Social Engineering People’s Credit Card Details

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2025/10/social-engineering-peoples-credit-card-details.html

Good Wall Street Journal article on criminal gangs that scam people out of their credit card information:

Your highway toll payment is now past due, one text warns. You have U.S. Postal Service fees to pay, another threatens. You owe the New York City Department of Finance for unpaid traffic violations.

The texts are ploys to get unsuspecting victims to fork over their credit-card details. The gangs behind the scams take advantage of this information to buy iPhones, gift cards, clothing and cosmetics.

Criminal organizations operating out of China, which investigators blame for the toll and postage messages, have used them to make more than $1 billion over the last three years, according to the Department of Homeland Security.

[…]

Making the fraud possible: an ingenious trick allowing criminals to install stolen card numbers in Google and Apple Wallets in Asia, then share the cards with the people in the U.S. making purchases half a world away.

Details About Chinese Surveillance and Propaganda Companies

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2025/09/details-about-chinese-surveillance-and-propaganda-companies.html

Details from leaked documents:

While people often look at China’s Great Firewall as a single, all-powerful government system unique to China, the actual process of developing and maintaining it works the same way as surveillance technology in the West. Geedge collaborates with academic institutions on research and development, adapts its business strategy to fit different clients’ needs, and even repurposes leftover infrastructure from its competitors.

[…]

The parallels with the West are hard to miss. A number of American surveillance and propaganda firms also started as academic projects before they were spun out into startups and grew by chasing government contracts. The difference is that in China, these companies operate with far less transparency. Their work comes to light only when a trove of documents slips onto the internet.

[…]

It is tempting to think of the Great Firewall or Chinese propaganda as the outcome of a top-down master plan that only the Chinese Communist Party could pull off. But these leaks suggest a more complicated reality. Censorship and propaganda efforts must be marketed, financed, and maintained. They are shaped by the logic of corporate quarterly financial targets and competitive bids as much as by ideology­—except the customers are governments, and the products can control or shape entire societies.

More information about one of the two leaks.

China Accuses Nvidia of Putting Backdoors into Their Chips

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2025/08/china-accuses-nvidia-of-putting-backdoors-into-their-chips.html

The government of China has accused Nvidia of inserting a backdoor into their H20 chips:

China’s cyber regulator on Thursday said it had held a meeting with Nvidia over what it called “serious security issues” with the company’s artificial intelligence chips. It said US AI experts had “revealed that Nvidia’s computing chips have location tracking and can remotely shut down the technology.”

Another Supply Chain Vulnerability

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2025/07/another-supply-chain-vulnerability.html

ProPublica is reporting:

Microsoft is using engineers in China to help maintain the Defense Department’s computer systems—with minimal supervision by U.S. personnel—leaving some of the nation’s most sensitive data vulnerable to hacking from its leading cyber adversary, a ProPublica investigation has found.

The arrangement, which was critical to Microsoft winning the federal government’s cloud computing business a decade ago, relies on U.S. citizens with security clearances to oversee the work and serve as a barrier against espionage and sabotage.

But these workers, known as “digital escorts,” often lack the technical expertise to police foreign engineers with far more advanced skills, ProPublica found. Some are former military personnel with little coding experience who are paid barely more than minimum wage for the work.

This sounds bad, but it’s the way the digital world works. Everything we do is international, deeply international. Making anything US-only is hard, and often infeasible.

EDITED TO ADD: Microsoft has stopped the practice.

New Mobile Phone Forensics Tool

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2025/07/new-mobile-phone-forensics-tool.html

The Chinese have a new tool called Massistant.

  • Massistant is the presumed successor to Chinese forensics tool, “MFSocket”, reported in 2019 and attributed to publicly traded cybersecurity company, Meiya Pico.
  • The forensics tool works in tandem with a corresponding desktop software.
  • Massistant gains access to device GPS location data, SMS messages, images, audio, contacts and phone services.
  • Meiya Pico maintains partnerships with domestic and international law enforcement partners, both as a surveillance hardware and software provider, as well as through training programs for law enforcement personnel.

From a news article:

The good news, per Balaam, is that Massistant leaves evidence of its compromise on the seized device, meaning users can potentially identify and delete the malware, either because the hacking tool appears as an app, or can be found and deleted using more sophisticated tools such as the Android Debug Bridge, a command line tool that lets a user connect to a device through their computer.

The bad news is that at the time of installing Massistant, the damage is done, and authorities already have the person’s data.

Slashdot thread.

Chinese-Owned VPNs

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2025/05/chinese-owned-vpns.html

One one my biggest worries about VPNs is the amount of trust users need to place in them, and how opaque most of them are about who owns them and what sorts of data they retain.

A new study found that many commercials VPNS are (often surreptitiously) owned by Chinese companies.

It would be hard for U.S. users to avoid the Chinese VPNs. The ownership of many appeared deliberately opaque, with several concealing their structure behind layers of offshore shell companies. TTP was able to determine the Chinese ownership of the 20 VPN apps being offered to Apple’s U.S. users by piecing together corporate documents from around the world. None of those apps clearly disclosed their Chinese ownership.

Communications Backdoor in Chinese Power Inverters

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2025/05/communications-backdoor-in-chinese-power-inverters.html

This is a weird story:

U.S. energy officials are reassessing the risk posed by Chinese-made devices that play a critical role in renewable energy infrastructure after unexplained communication equipment was found inside some of them, two people familiar with the matter said.

[…]

Over the past nine months, undocumented communication devices, including cellular radios, have also been found in some batteries from multiple Chinese suppliers, one of them said.

Reuters was unable to determine how many solar power inverters and batteries they have looked at.

The rogue components provide additional, undocumented communication channels that could allow firewalls to be circumvented remotely, with potentially catastrophic consequences, the two people said.

The article is short on fact and long on innuendo. Both more details and credible named sources would help a lot here.

Chinese AI Submersible

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2025/05/chinese-ai-submersible.html

A Chinese company has developed an AI-piloted submersible that can reach speeds “similar to a destroyer or a US Navy torpedo,” dive “up to 60 metres underwater,” and “remain static for more than a month, like the stealth capabilities of a nuclear submarine.” In case you’re worried about the military applications of this, you can relax because the company says that the submersible is “designated for civilian use” and can “launch research rockets.”

“Research rockets.” Sure.

China Sort of Admits to Being Behind Volt Typhoon

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2025/04/china-sort-of-admits-to-being-behind-volt-typhoon.html

The Wall Street Journal has the story:

Chinese officials acknowledged in a secret December meeting that Beijing was behind a widespread series of alarming cyberattacks on U.S. infrastructure, according to people familiar with the matter, underscoring how hostilities between the two superpowers are continuing to escalate.

The Chinese delegation linked years of intrusions into computer networks at U.S. ports, water utilities, airports and other targets, to increasing U.S. policy support for Taiwan, the people, who declined to be named, said.

The admission wasn’t explicit:

The Chinese official’s remarks at the December meeting were indirect and somewhat ambiguous, but most of the American delegation in the room interpreted it as a tacit admission and a warning to the U.S. about Taiwan, a former U.S. official familiar with the meeting said.

No surprise.

China, Russia, Iran, and North Korea Intelligence Sharing

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2025/03/china-russia-iran-and-north-korea-intelligence-sharing.html

Former CISA Director Jen Easterly writes about a new international intelligence sharing co-op:

Historically, China, Russia, Iran & North Korea have cooperated to some extent on military and intelligence matters, but differences in language, culture, politics & technological sophistication have hindered deeper collaboration, including in cyber. Shifting geopolitical dynamics, however, could drive these states toward a more formalized intell-sharing partnership. Such a “Four Eyes” alliance would be motivated by common adversaries and strategic interests, including an enhanced capacity to resist economic sanctions and support proxy conflicts.

Silk Typhoon Hackers Indicted

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2025/03/silk-typhoon-hackers-indicted.html

Lots of interesting details in the story:

The US Department of Justice on Wednesday announced the indictment of 12 Chinese individuals accused of more than a decade of hacker intrusions around the world, including eight staffers for the contractor i-Soon, two officials at China’s Ministry of Public Security who allegedly worked with them, and two other alleged hackers who are said to be part of the Chinese hacker group APT27, or Silk Typhoon, which prosecutors say was involved in the US Treasury breach late last year.

[…]

According to prosecutors, the group as a whole has targeted US state and federal agencies, foreign ministries of countries across Asia, Chinese dissidents, US-based media outlets that have criticized the Chinese government, and most recently the US Treasury, which was breached between September and December of last year. An internal Treasury report obtained by Bloomberg News found that hackers had penetrated at least 400 of the agency’s PCs and stole more than 3,000 files in that intrusion.

The indictments highlight how, in some cases, the hackers operated with a surprising degree of autonomy, even choosing targets on their own before selling stolen information to Chinese government clients. The indictment against Yin Kecheng, who was previously sanctioned by the Treasury Department in January for his involvement in the Treasury breach, quotes from his communications with a colleague in which he notes his personal preference for hacking American targets and how he’s seeking to ‘break into a big target,’ which he hoped would allow him to make enough money to buy a car.

US Treasury Department Sanctions Chinese Company Over Cyberattacks

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2025/01/us-treasury-department-sanctions-chinese-company-over-cyberattacks.html

From the Washington Post:

The sanctions target Beijing Integrity Technology Group, which U.S. officials say employed workers responsible for the Flax Typhoon attacks which compromised devices including routers and internet-enabled cameras to infiltrate government and industrial targets in the United States, Taiwan, Europe and elsewhere.

IoT Devices in Password-Spraying Botnet

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2024/11/iot-devices-in-password-spraying-botnet.html

Microsoft is warning Azure cloud users that a Chinese controlled botnet is engaging in “highly evasive” password spraying. Not sure about the “highly evasive” part; the techniques seem basically what you get in a distributed password-guessing attack:

“Any threat actor using the CovertNetwork-1658 infrastructure could conduct password spraying campaigns at a larger scale and greatly increase the likelihood of successful credential compromise and initial access to multiple organizations in a short amount of time,” Microsoft officials wrote. “This scale, combined with quick operational turnover of compromised credentials between CovertNetwork-1658 and Chinese threat actors, allows for the potential of account compromises across multiple sectors and geographic regions.”

Some of the characteristics that make detection difficult are:

  • The use of compromised SOHO IP addresses
  • The use of a rotating set of IP addresses at any given time. The threat actors had thousands of available IP addresses at their disposal. The average uptime for a CovertNetwork-1658 node is approximately 90 days.
  • The low-volume password spray process; for example, monitoring for multiple failed sign-in attempts from one IP address or to one account will not detect this activity.

No, The Chinese Have Not Broken Modern Encryption Systems with a Quantum Computer

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2024/10/no-the-chinese-have-not-broken-modern-encryption-systems-with-a-quantum-computer.html

The headline is pretty scary: “China’s Quantum Computer Scientists Crack Military-Grade Encryption.”

No, it’s not true.

This debunking saved me the trouble of writing one. It all seems to have come from this news article, which wasn’t bad but was taken widely out of proportion.

Cryptography is safe, and will be for a long time

What’s new in Cloudflare One: Digital Experience (DEX) monitoring notifications and seamless access to Cloudflare Gateway with China Express

Post Syndicated from Guy Nir original https://blog.cloudflare.com/whats-new-in-cloudflare-one-digital-experience-dex-monitoring-notifications

At Cloudflare, we are constantly innovating and launching new features and capabilities across our product portfolio. We are introducing roundup blog posts to ensure that you never miss the latest updates across our platform. In this post, we are excited to share two new ways that our customers can continue to keep their web properties performant and secure with Cloudflare One: new Digital Experience Monitoring (DEX) notifications help proactively identify issues that can affect the end-user digital experience, and integration with China Express enables secure access to China-hosted sites for Cloudflare Gateway customers.   

Using DEX Notifications for proactive monitoring with Cloudflare Zero Trust


As with other notification types, DEX notifications can be configured and reviewed from Cloudflare dashboard notifications.

What problem does it solve?

DEX notifications address the challenge of proactively identifying issues affecting the digital experience of your end users. By monitoring device health and conducting synthetic tests from WARP clients deployed on your fleet’s end-user devices, DEX provides valuable insights. These notifications empower IT administrators to quickly identify and address connectivity and application performance problems before they impact a wide range of users.

By proactively notifying administrators when problems arise, DEX helps minimize user disruption and provides peace of mind. Instead of actively refreshing and looking for issues as before, administrators can now receive immediate notifications. Management is simple, as notifications can be easily configured through the Cloudflare dashboard.

Administrators can now create three new notification types:

1) Device Connectivity Anomaly

Are you tired of manually monitoring your end-users’ device connectivity? Do you want to be notified immediately when there’s a sudden change? Our new DEX notification for Device Connectivity Anomaly alerts you when there’s a significant increase or decrease in the number of monitored devices connecting or disconnecting to the WARP Client. This can be filtered by various characteristics such as data center (“colo”), platform (operating system), and WARP Client version.

We use a statistical method called z-score to detect anomalies in monitored device count. A z-score measures how many standard deviations a data point is from the mean. By comparing the current five minutes of data to the past four hours, we can calculate the mean and standard deviation. If the z-score value exceeds 3.5 or falls below -3.5, a notification is triggered.

Here’s an example of a notification configuration for macOS devices in the UK using WARP Client version 2023.7.24:


2) DEX Test Latency 

Ever worry application performance is slow? We’re thrilled to introduce DEX Test Latency notifications, which are designed for administrators who want to stay ahead of the curve when it comes to application performance. This notification proactively alerts you of significant spikes or drops in latency based on:

  • HTTP Test: Resource Fetch Time measures the time it takes for a web browser to retrieve a specific resource from your application and deliver it to the end user.

  • Traceroute Test: Round Trip Time measures the average time it takes for data packets to travel from your device to a specific destination IP address and back (when successful). Traceroute tests focus on the overall network performance between the test client/device and your application.

This notification can be filtered by various characteristics such as data center (“colo”), platform (operating system), WARP Client version, and test name.

In this example, you have a DEX test monitoring the latency of the website www.cloudflarestatus.com. This test, named “Cloudflare Status,” uses an HTTP GET request and runs on Windows devices connecting through the Lisbon colo (data center). 


3) DEX Test Low Availability

Is application downtime causing headaches for you and your users? 

DEX Test Low Availability notifications help maintain optimal application health by notifying you when availability  falls below a given threshold. This notification monitors the success rate of HTTP or Traceroute requests sent to an application through pre-configured DEX tests. These synthetic tests simulate user traffic and measure the percentage of successful interactions with your application.

You define the Service Level Objective (SLO) — a specific availability threshold — for each notification. When the percentage of successful requests falls below this threshold, you’ll receive immediate notification, allowing you to proactively address issues before they impact a wide range of end users.

This can be filtered by various characteristics such as colo (data center), platform (operating system), WARP Client version, and test name.

In this example, a DEX test is targeting www.google.com. This Traceroute test runs on Chrome OS devices connecting through the Tel Aviv colo. The example notification is configured to alert you whenever the availability (percentage of successful requests) drops below 98%, allowing you to investigate potential issues and take corrective action quickly.


Get started today

DEX notifications are now available for Cloudflare One customers. They can be configured by going to Cloudflare Dashboard > Account home > Notifications > Add, and then selecting any of the three DEX notification types. For more information, refer to Create a notification. DEX notifications are one of the many ways the Cloudflare One suite of solutions work seamlessly together as a unified platform to find and fix security issues across SaaS applications.

Seamless access to Cloudflare Gateway with China Express


In January 2023, we proudly launched China Express with multiple partners in China to extend Cloudflare One into China and provide connectivity to ensure that customers within the country could enjoy the same level of access to global services as the rest of the world. Our goal was simple: to deliver a consistent experience for customers and employees everywhere.

Over the past year, we’ve observed a notable increase in demand from enterprise customers seeking secure access to China-hosted sites. These customers, who often require consistent zero trust security policies applied through Cloudflare Gateway, including device posture checks, have faced challenges like scenic routing, where Internet traffic passes through multiple countries or networks, leading to significant packet loss when connecting to these websites.

Understanding the problem

For example, a global company with offices in both Hong Kong and San Jose has implemented WARP on their devices to manage Internet access. As part of their daily operations, employees need to access websites hosted in mainland China. However, they have experienced unstable connections, particularly when accessing the AWS web console in China. Further investigation revealed long and sometimes unpredictable network routes, contributing to the instability.

Global Internet traffic to and from China flows through a limited number of international links, tightly regulated by government authorities, often leading to significant instability and fluctuations. To address these challenges, our China Express partners offer the ‘Reverse Tunnel’ solution, a reliable service that ensures stable access to Chinese websites, effectively mitigating connectivity issues.

Reverse tunnel

Today, we are thrilled to announce a significant enhancement to China Express: a new offering tailored to the needs of global Cloudflare Gateway customers accessing China-hosted sites. This enhancement introduces a dedicated tunnel configuration, ensuring safe and predictable connectivity while maintaining stringent zero trust security policies.

By partnering with JD Cloud, one of our trusted local providers in China, we’ve developed a solution that seamlessly integrates with Cloudflare’s Zero Trust Firewall DNS Policies by:

Directly routing through our Cloudflare Hong Kong data center: When global Cloudflare Gateway customers attempt to access China-hosted sites, their traffic is routed directly to our Hong Kong data center. This strategic routing point allows us to apply Zero Trust policies before the traffic continues its journey into China.

Using JD Cloud’s connectivity tunnel: From our Cloudflare Hong Kong data center, the traffic is then securely transmitted through JD Cloud’s private tunnel infrastructure, ensuring reliable and efficient connectivity into China. This partnership with JD Cloud leverages their local expertise and infrastructure capabilities, further enhancing the reliability and performance of the connection. 

Note: This premium service is exclusive to China Network customers and requires a dedicated reverse tunnel contract with JD Cloud.

Key benefits

This solution offers several key benefits for our customers:

  • Improved stability: By directing all traffic to a dedicated tunnel, customers experience more reliable connections to websites within China.

  • Enhanced security: Zero Trust policies are consistently applied to all traffic, regardless of its destination, ensuring the highest level of security for customers accessing China-hosted sites.

  • Seamless customer experience: With a dedicated tunnel configuration, customers can access websites in China with confidence, knowing that their connections are both safe and predictable. Whether it’s multinational corporations expanding into the Chinese market, e-commerce platforms serving Chinese customers, or remote workers accessing corporate resources from within China, Cloudflare’s China Express with JD Cloud partnership provides a solution tailored to their specific needs.

Conclusion

By having companies implement a DNS host override policy in Cloudflare Gateway for origins in China, which routes traffic through the China Express Reverse Tunnel instead of using public Internet routes, companies can ensure more stable and reliable connections for their employees.

Looking ahead, we remain committed to continuously improving and expanding our offerings within China Express. Future developments may include further enhancements to performance, additional partnerships with local providers, and ongoing innovation to meet the evolving needs of our customers in the region.

Deebot Robot Vacuums Are Using Photos and Audio to Train Their AI

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2024/10/deebot-robot-vacuums-are-using-photos-and-audio-to-train-their-ai.html

An Australian news agency is reporting that robot vacuum cleaners from the Chinese company Deebot are surreptitiously taking photos and recording audio, and sending that data back to the vendor to train their AIs.

Ecovacs’s privacy policy—available elsewhere in the app—allows for blanket collection of user data for research purposes, including:

  • The 2D or 3D map of the user’s house generated by the device
  • Voice recordings from the device’s microphone
  • Photos or videos recorded by the device’s camera

It also states that voice recordings, videos and photos that are deleted via the app may continue to be held and used by Ecovacs.

No word on whether the recorded audio is being used to train the vacuum in some way, or whether it is being used to train a LLM.
