Are USB-to-Ethernet Dongles Really Spying on You? A Deep Dive Into the Malware Claims
Recently, a viral video sparked widespread concern by alleging that certain USB-to-Ethernet dongles contain malware designed to spy on users. The claims suggested that these devices, allegedly manufactured by China and Russia, were part of a covert surveillance operation. But how much of this is fact, and how much is fear-mongering?
When [lcamtuf] investigated the topic, he discovered that the reality was far less sinister. The video in question focused on an additional SPI Flash chip found on the dongle’s PCB, alongside the USB 2.0 – Ethernet IC. This chip became the center of numerous conspiracy theories, with speculations ranging from espionage to data theft.Though, [lcamtuf]’s research revealed that the IC used in these dongles, the SR9900, is manufactured by CoreChips Shenzhen. It appears to be a clone of the 2013-era Realtek RTL8152B. Both chips feature an external SPI Flash option, which is used to present a virtual CD drive to the user when the dongle is plugged in. This functionality was confirmed by the SR9900 Windows system mass production tool, which [lcamtuf] obtained. The tool includes a 168 kB ISO image containing the SR9900 driver package, perfectly fitting the 512 kB Flash chip.While the possibility of backdoors or malware in hardware and firmware can never be entirely ruled out, this particular case seems to be more of a nostalgic nod to the era of driver installation CDs than a modern-day espionage tool. As [lcamtuf] aptly put it, this is “a cruel reminder that 2013 is now already vanishing into the realm of retro computing.”

are USB-to-Ethernet Dongles Spying on You? Unpacking the Malware Claims with Cybersecurity Expert Dr. Emily Carter
Recently,a viral video sparked widespread concern by alleging that certain USB-to-Ethernet dongles contain malware designed to spy on users. The claims suggested that these devices, allegedly manufactured in China and Russia, were part of a covert surveillance operation. But how much of this is fact,and how much is fear-mongering? To shed light on the matter,we sat down with Dr. Emily Carter, a cybersecurity expert and hardware forensic analyst, to discuss the examination findings and the broader implications for hardware security.
Senior Editor: Dr. Carter, thank you for joining us. Let’s start with the viral claims. What exactly were people alleging about these USB-to-Ethernet dongles?
Dr.Emily Carter: Thank you for having me. the controversy began when a video surfaced claiming that certain USB-to-Ethernet dongles contained hidden malware. The video pointed to an additional SPI Flash chip on the device’s PCB as evidence of malicious intent. The narrative suggested that this chip was being used for espionage or data theft, which naturally caused a lot of alarm.
Senior Editor: That sounds pretty serious. What did the investigation reveal about these claims?
Dr. Emily carter: The investigation, led by cybersecurity researcher lcamtuf, found that the claims were largely overblown. The additional SPI Flash chip wasn’t for malware—it was actually used to present a virtual CD drive to the user. This is a common practice for driver installation, especially in older hardware. The chip contained a 168 kB ISO image with the necessary drivers for the dongle, which fits perfectly within the 512 kB Flash chip.
The Hardware: What’s Inside These Dongles?
Senior editor: Let’s talk about the hardware itself. What did the investigation uncover about the chips used in these dongles?
Dr. Emily Carter: The dongle in question uses an IC called the SR9900, manufactured by CoreChips Shenzhen. This chip is essentially a clone of the 2013-era Realtek RTL8152B. Both chips have an external SPI Flash option, which is what we’re seeing here. The Flash chip is used to store the driver package, which is then presented as a virtual CD drive when the dongle is plugged in. This is a throwback to the days when driver installation CDs were common.
Senior Editor: So, it’s more of a relic of older tech practices than a modern espionage tool?
Dr. Emily Carter: Exactly. while the idea of hardware-based malware is certainly plausible, this particular case seems to be more about outdated design choices than malicious intent. That said, it’s always good to scrutinize hardware and firmware for potential vulnerabilities, as the possibility of backdoors or malware can never be entirely ruled out.
The Broader Implications: What Does this Mean for Hardware Security?
Senior Editor: This case has sparked a lot of discussion about the intersection of hardware and cybersecurity. What are your thoughts on the broader implications?
Dr. Emily Carter: This incident serves as a reminder that hardware security is just as vital as software security. While this particular dongle appears to be harmless, it highlights the need for greater transparency and scrutiny in the hardware supply chain. Consumers and organizations should be aware of the potential risks associated with third-party hardware, especially when it comes to devices that handle sensitive data.
Senior Editor: What steps can people take to protect themselves from potential hardware-based threats?
Dr. Emily Carter: first and foremost,always purchase hardware from reputable sources. Be cautious of devices that seem too good to be true, especially if they’re substantially cheaper than comparable products. Additionally, keep your firmware and drivers up to date, as manufacturers often release patches to address security vulnerabilities. consider using tools that can analyze hardware and firmware for potential risks, especially in high-stakes environments.
Conclusion: A Lesson in Vigilance
Senior Editor: Dr. Carter, thank you for sharing your insights. It’s clear that while the viral claims may have been exaggerated, they’ve sparked an important conversation about hardware security. Any final thoughts for our readers?
Dr. Emily Carter: My pleasure. I’d just like to emphasize that while this particular case appears to be harmless, it’s a good reminder to remain vigilant about the devices we use.Cybersecurity is a constantly evolving field, and staying informed is one of the best ways to protect yourself.
