Here are the tips which can save you from these types of attacks:

Two-factor authentication:

Various online portals like Facebook, Google, Twitter, PayPal, etc. offers you the tight security by enabling two-factor authentication. Site sends you a code (temporary password) to your phone via SMS or Email. It ensures your account security and more secure than a regular, old password.

Prefer HTTPS while browsing:

Most of world’s famous internet browsers like Chrome, Mozilla, Opera, & Safari offers HTTPS by default and some converts the website into it. This extension brought to us by the Electronic Frontier Foundation and the Tor Project. It encrypts the website data which makes difficult for intruders to steal information.

Keep your software & OS updated.

This one’s easy enough. Make sure to install the recommended refreshes when new software rolls out, as updated security patches are usually released, too. Recently, Microsoft released the security patches for its oldest and outdated OS Windows XP and Windows 7 too, that made the old PC again secure.

Turn off Wi-Fi, Bluetooth, direct sharing software:

Whenever you leave your home, aka a secure network, turn off your Wi-Fi, Bluetooth, Xender, etc. for added security. Direct sharing software may be vulnerable if one of the smartphones is affected.

Use secured messaging app:

Some of the app like WhatsApp, Signal, Telegram, Facebook Messenger, etc. are using end-to-end decryption that is again secured from hackers and your data is safe.

Email links:

Before clicking on the link sent in email, make sure it is secure enough. Either open it in secured browser provided by your antivirus or just hover your mouse and see it in your browser status bar, where it will redirect you.

Use VPN sometime:

A virtual private network is like a firewall for when you’re online on a public network, like at Starbucks, Jio Free Wi-Fi, London Metro, etc. Basically, it makes it as if you’re online on a private network by encrypting data. You can sign up to use a VPN provider to do so.


Passwords are somewhat key parameters when you feel that your account has been hacked. Some the famous algorithms like Brute-Force, RainbowCrack are capable enough to get your password which is based on your general info like DOB, Maiden Name, etc.

Back up your files:

In case, if you still feel vulnerable, backup your file to cloud. It will be the best option to restore your files even if hackers have grabbed your hard-disk. You can also back-it up in external HD too.
