Amazon earlier this April addressed a critical vulnerability in its Kindle e-book reader platform that could have been potentially exploited to take full control over a user's device, resulting in the theft of sensitive information by just deploying a malicious e-book. "By sending Kindle users a single malicious e-book, a threat actor could have stolen any information stored on the device, from Amazon account credentials to billing information," Yaniv Balmas, head of cyber research at Check Point, said in an emailed statement. "The security vulnerabilities allow an attacker to target a very specific audience." In other words, if a threat actor wanted to single out a specific group of people or demographic, it's possible for the adversary to choose a popular e-book in a language or dialect that's widely spoken among the group to tailor and orchestrate a highly targeted cyber attack.

"The code runs as root, and the attacker only needs to know the email address assigned to the victim's device,"  said  Yogev Bar-On, a security researcher for Readlmode Labs, in a technical write-up on Thursday. The first vulnerability lets a bad actor send an e-book to a Kindle, the second flaw allows for remote code execution while the e-book is parsed, and a third issue makes it possible to escalate privileges and run the code as the "root" user. When linked together, these weaknesses
