Scammers have always been around, but over the pandemic there's been a huge increase in fraudsters trying to steal people's cash.
During the crisis there have been lots of scams identified as criminals try to get their hands on personal details and people's money.
From fake Royal Mail and delivery scams to online shopping and bank scams, there are lots of fraudsters trying to catch people out.
Lots of these scams are very sophisticated and it can be hard to know when you're being scammed.
Criminals can sound very convincing and often try to get you to panic by telling you something is urgent and needs immediate action.
In light of this, Money Saving Expert Martin Lewis has revealed some of the key signs that people should be looking out for if they think they could be being scammed.
Speaking on Lorraine earlier this week Martin said: "If your bank calls you up and tells you that there's an urgency, just a few signals that you have to understand, if they pressure you, they say it's urgent and that you can't tell anyone else, those are massive signs that someone is trying to scam you.
"If you see an investment ad that says 'put in £250' and they call you and say 'it's going well but you need to put in more money', you're being scammed on the back of that.
"If you get called up by your bank and get asked for your password details.
"If you're not sure it's your bank or they call you up in urgency you put the phone down, you go and find the number yourself and this is the important bit you call them back on a different phone."
