David Schwartz, Chief Technology Officer of Enterprise Blockchain Company Ripple, has already been I commented Recently discovered Bluetooth vulnerabilities have affected nearly a billion devices.
“Not good,” the architect behind the XRP ledger said in a recent social media post.
Earlier this week, Tarlogic, a Spanish company specializing in cybersecurity, revealed that it had discovered a backdoor with a widely used ESP32 microcontroller.
According to Tarlogic, the low-cost chips that can be purchased for around $2 are listed in “Most of Bluetooth IoT devices.” Examples of such devices include smartwatches, smartlocks, LED controllers, fitness trackers, IoT-enabled speakers, and security cameras.
However, we can see that the chip can infect malicious code because of the hidden commands. Tarlogic has discovered a total of 29 commands that have not been previously documented.
This undocumented backdoor could allow bad actors to access their devices using the ESP32 chip, even when offline. Their motivations range from sensitive personal data theft to spying.
That said, some commentators question whether undocumented commands actually qualify as backdoors.
Espressif, the Chinese semiconductor company behind the chip, has yet to comment on the recent discoveries. Furthermore, there appears to be no easy solution to this problem that does not involve replacing all the hardware.
Last year, Schwartz warned about a Windows Vulnerabilities This allowed the attacker to execute arbitrary code within Wi-Fi range.
