The Dhaka Times Desk Smartphone users keep their important information and work on the smartphone from the computer or many other things. And hackers are now focusing more on smartphones than computers.

Smartphone users connect to the Internet and perform various bill payment services including banking on the phone. Also, they keep various important information on the smartphone, which can be lost if it is in someone else's hands. Also, are you planning to sell your old smartphone and buy a new smartphone? So be careful, because hackers are most interested in old mobile phones.
Generally, we use the smartphone only if we give it a net connection, otherwise the smartphone does not work fully, currently some of the important tasks include bank account information, debit-credit card information or other financial account information. And if these information gets into the hands of hackers, the users will have to face a big loss.
Nowadays many people do their various tasks like banking, e-shopping, or other tasks. And the debit or credit card information used in these activities can easily get into the hands of hackers.
After a study on this subject, Sandeep Sengupta, co-founder and director of the Indian School of Ethical Hackers, said at the ICT 2014 conference, "Even after deleting the phone memory or memory card, various information remains there. This information is easily recoverable until other data overwrites that space. And so it is reasonable to overwrite any other data there instead of deleting it. Otherwise this big disaster can happen."
He also said that hackers have now targeted mobile phones. And so he advises users to be very careful about this.
As a result, your favorite smartphone is no longer safe from hackers, so be careful when sharing your important information and think twice before giving the phone to someone else.
