Good e-Reader There have been a number of critical vulnerabilities discovered on the entire Amazon Kindle line of e-readers. The attacks could give hackers access to your entire device. Amazon has issued a patch to close all of the loopholes and everyone is encouraged to download the 5.13.4. firmware update right away, even people who have elected to root their device. Researcher Yogev Bar-On, of Readlmode Labs, who discovered the now-patched issue, detailed in a blog post on how he was able to access a victim’s Amazon account simply by knowing their email address. The attack – dubbed ‘KindleDrip’ – relied on three vulnerabilities found in the e-reader. The first bug allowed a spoofed email address to bypass authentication checks, enabling a malicious e-book file to be sent to a victim’s device. Amazon’s ‘Send To Kindle’ feature gives users the option to send a purchase directly to their device using a list of pre-approved senders such as their Kindle email address, which is automatically generated by Amazon.
