The Controversial Allegations

In recent weeks, a sensational video has ignited controversy, alleging that certain USB-to-Ethernet dongles are embedded with "malware." These dramatic claims suggest that the devices, reportedly designed by entities in China and Russia, monitor users without their consent. But how grounded in reality are these assertions?

Investigating the Claims

Upon deeper investigation by tech researcher [lcamtuf], what emerged wasn't a significant security threat but rather a throwback to earlier computing days, particularly during the transition from drivers on CD to USB installations.

The SPI Flash Chip Mystery

The specific component in question was an extra SPI Flash chip located on the printed circuit board alongside the USB-to-Ethernet integrated circuit (IC). This setup has led to rampant conspiracy theories speculating its purpose. However, [lcamtuf] uncovered that the IC in these dongles, designated as SR9900, is manufactured by CoreChips Shenzhen. Intriguingly, it appears to be a clone of the older, well-known Realtek RTL8152B model from 2013.

Functionality and Intention

Both chipsets include an external SPI Flash capability, which allows the dongle to present a "virtual CD drive" when plugged into a computer. This functionality ties back to a Windows system mass production tool that [lcamtuf] managed to obtain, revealing a 168 kB ISO image containing the drivers for the SR9900. This file conveniently fits within the 512 kB capacity of the Flash chip, demonstrating that the intention was likely user convenience rather than malicious intent.

Conclusion: Separating Fact from Fiction

While it’s crucial to remain vigilant about potential vulnerabilities in chips and firmware—including the risk of backdoors and malware—this particular case appears to stem from a misunderstanding of technology rather than a deliberate act of espionage.

Final Thoughts

So, are these USB-to-Ethernet dongles truly a means of spying on users, or are they simply artifacts from an outdated technological era? As we delve further into the world of rapidly evolving devices, it’s essential to approach such claims skeptically and seek clarity over sensationalism. Always stay updated on cybersecurity measures, but don't let paranoia cloud your judgment in the realm of tech!
