Researchers have recently discovered a security vulnerability targeting Amazon Kindle and Echo devices. The KRACK WiFi vulnerability discovered back in 2017 still affects these Amazon devices.
Security researchers from the ESET Smart Home Research Team have recently highlighted a vulnerability targeting Amazon Kindle and Echo devices. They have found these devices exposed to KRACK (Key Reinstallation Attack) vulnerabilities. The researchers have described their findings in detail in a blog post.
In summary, team ESET tested numerous Amazon devices for their vulnerability to KRACK attacks. They disovered the Amazon Kindle 8th generation and Amazon Echo 1st generation to possess these flaws. They could even replicate the attack using the original script from the researchers who first reported KRACK.
Specifically, KRACK vulnerabilities affected the security of data transmitted over WiFi. These vulnerabilities allowed interception from data packets, access information by decrypting the data, and execute DoS attacks.
KRACK primarily affected old devices. It therefore required vendors to release new firmware for the susceptible hardware. While most vendors patched the flaw, these Amazon devices listed above still remained open to KRACK attacks.
