Unfortunately, piracy has become commonplace on the Internet. And one of the biggest blunders you can make if to think that it will only happen to others, that if you don’t do anything, you’ll never have a problem. Unfortunately, it’s not so simple. So how can you know if your account has been hacked? How can you know if you’ve been hacked? Let’s start with some basic elements:
Check if you’ve activated maximum security
Have you enabled all security settings? For example, some services use a 2-step verification system. The odds of being hacked with this feature are minimized, and even if this were to happen, you would be notified. For example, Google, Facebook and Dropbox will send you a message to let you know that someone has tried to access your account from a new device.
Check how safe your password is
Not all websites offer a wide range of security options. You must therefore think long and hard on the main element for confidentiality: the password. So the secure password must have a mix of numbers, letters and sometimes special characters. Make sure you get creative with your password and make sure it’s not just a single word with characters at the start or end.
Look at the symptoms
In theory, your account may have been hacked without you even realizing it. In practice, it’s less obvious because if someone has bothered to get hold of your account details, they probably plan to do something with it. Either they’ll use your account directly, for example change your password, purchase things from your account or send spoof mail to your contacts, or they’ll use it indirectly to scrape other information they find in your account. Thus, they can use/sell your personal data, etc.
Check online if you have been hacked
If piracy is done on a large scale, you can check whether you were hacked or not. A security expert has created a list of all the victims after every known attack, and allows users to check if their account was hacked. You just have to type in your email address, and the website will tell you whether or not someone knows your password.
