You've probably heard about credit fraud - the deliberate use of someone else's credentials to open accounts, buy goods, and obtain cash advances. This is the most common type of identity theft. Another example of cybercrime involves the use of stolen mobile/computers and information.
Beware of Card Not Present transactions - these are purchases made with your credit card when you weren't present. These are typical scams, and the only way to identify them is to check your bank statements and bank apps for errors/frauds.
