Amazon Echo Dot Does Not Wipe Personal Content Even After Factory Reset Concerning Users All Over The World

These days I guess with the increased inventions of IoT also known as the Internet of Things we have learned to be more dependent on these gadgets without even knowing the repercussions of the things. So what exactly is this IoT? The Internet of things (IoT) describes the network of physical objects that are embedded with sensors, software, and other technologies for the purpose of connecting and exchanging data with other devices and systems over the Internet. Things have evolved due to the convergence of multiple technologies, real-time analytics, machine learning, ubiquitous computing, commodity sensors, and embedded systems along with wireless sensor networks, control systems, automation, and others all contribute to enabling the Internet of things. In short, if you have this kind of item a home your home is called a smart home and, to be honest, the presence of this all makes you even lazier already this lockdown has done a lot of damage to our fitness now with these smart home appliances will definitely add onto that although it has its own perks like it can come to ur benefit if you are in danger or if it’s some kind of emergency. 

But recent news has brought out a problem of this IoT that even after factory reset the Amazon Echo Dot which is a very popular example of IoT does not get rid of all your private information and the manufacturer should look into it as soon as possible because a factory reset should be removing all that but that is not the case and it is very dangerous especially with cybercrime at its peak. As the Amazon Echo Dot consists of its user’s WiFi passwords, outer MAC addresses, and Amazon logins among other pieces of sensitive information. And if you think this is just a rumor or it is not a piece of true news them let me just clarify this thing with you my dear readers the fact that the Amazon Echo Dot doesn’t erase all of a user’s personal information has been researched using 86 used Amazon Echo Dots if it was only one or two out of these 86 the reason why it didn’t erase the information may have been because there was a fault in the device but all 86 not erasing the data after factory reset now that isn’t some coincidence is it?

This research has been carried out by Northeastern University which bought 86 used Echo Dots from eBay and flea markets and additionally purchased six new Dots and loaded test data onto them. More than half of the secondhand devices had not even had the most basic factory reset done but even when a factory reset had been performed, the researchers were able to access the personal data that had previously been stored by using a publicly available forensic tool known as Autopsy. The reason behind this issue is that most of the IoT devices use Flash memory which makes it more difficult to permanently remove data because it is designed to only allow a finite number of delete cycles before a memory block becomes inoperable. And for the factory reset to completely delete this Flash memory it will require more specialized equipment. 

So I think that the manufacturer should at least add a layer of encryption so that the personal information is not readily available for everyone and yes, the data may still not be hundred percent protected but adding a layer of encryption makes it difficult for hackers to enter.
