Phishing is an illegitimate method of extracting the personal and other financial details of a person.
Basically, it is a process of tricking a person on the internet to retrieve their banking passwords, bank accounts, phone number, credit card details, etc.
This practice has grown over exponentially over last few years.
The imposters send you emails that can lure you into entering your personal details somehow into the mails sent by them and once they get what they want, they will raise a toast and have a bash on your hard-earned money.
The laws and police have become very vigilant and tough to nail these kinds of fraudsters.
The preferred mode of Phishing is via sending fraudulent emails.
Note, though, that reputed organizations like Amazon, eBay and banks never ask anyone for their password in their emails.
Next, whenever you open a phishing email, then the link in that mail will always open a site that has no security encryption.
For instance, the valid url of the site will not have HTTPS at the beginning and many email links have some other extension like .rs at the end of the email.
Moreover, the format of the email is very generic whereas the reputed organization always refers to you with your customer id number in their emails.
The most effective manner to remain protected from phishing scams is that you have enough knowledge to recognize one instantly.
However, installing pop up blockers and spam filters in your browser is yet another step you can follow.
