What is the difference between blagging and phishing?

First you'd need to know each definition separately to differentiate and distinguish.

Blagging is to persuade someone in a clever or slightly dishonest way to allow you to do something or to give you something.

Phishing is simply cloning a legit site to fraudulently obtaining private information, often using email or SMS.

This two mentioned above are similar, and are both social engineering attacks, they convince, persuade, Spoof, etc. All sort of things possible just to make the victim feel safe and sure he/she's on the right and legit place.

The key difference between phishing and blagging, is that blagging is targeted towards one individual, whilst phishing is broader and hopes to get someone to bite.
