The abbreviation " VPN " has slowly become established among average Internet users, which is certainly good, but the problem is that people have started to see VPN as the ultimate solution to all problems.
A real drama has emerged on the internet after Avast! tested several used smart devices and managed to "dig out" deleted private information.
Namely, experts from the Avast company bought 20 used phones with a factory reset, to delete all the data, but they managed to get most of the information and content that was in those devices.
How to?
In fact, there is no wisdom, there are a bunch of free tools with which you can restore all files in a few clicks. You may have used them to recover accidentally deleted images, documents, and other important files. This is possible because when you delete a file it is actually still in memory but the information about its existence has been deleted. So another file can be recorded over it, and only then does it disappear.
Every smart device that has the option to reset to factory settings, to delete files faster, uses the classic delete method so that all these files actually remains in the device. You can restore all of these files later with the Recover Deleted Files tool.
What do people do?
Those who know about this, and who find it interesting, buy a used phone and "dig up" private information from the owner. Of course, if the owner does not know that resetting the phone does not delete the information completely, he can get into an awkward situation.
Since you now know that this is possible, you will do a thorough deletion of data from the phone BEFORE resetting to factory settings. The method is known as "wipe drive".
Data recovery tools are e.g. Undelete DiskDigger and the like.
