Even though the SNS is hacked, even if the owner of the account does not notice any noticeable movements, it may not be noticed. The method for checking whether your SNS account is hacked is as follows.

◆ In order to manage passwords securely
Linking with Twitter The application does not ask for the password directly, but instead requests to enter the sign-in information of the Twitter account. This is the same on Facebook, and third party applications requesting federation certification do not need to enter their own login information.

Phishing attacks are dressed as websites when a user clicks a dangerous link and they prompt the user to log in to a fake login screen. Once login information is entered, you log in to SNS using the information entered by the user, rewrite the account information, or share the information from the user's account.

The first countermeasure against these is to know the URL of the site to be browsed. Check if the URL displayed in the address bar of the browser is the same as the site you plan to browse and check if the security certificate fits exactly. For example, if you are browsing GIGAZINE and the URL is not displayed as "gigazine.net", it means that it is a dangerous site.

Then it checks whether the mail address of the default setting of the hacked account has been changed from the one set up. We also scanned the virus to see if the computer was infected with the virus, and finally the account was hacked against friends and followers, so the message sent during that time is not what you sent, If you tell the fact that you are OK.
