Every time you search for purchases on the Internet, you need to be careful with websites that you do not understand, have no relationship, have no trust or you have not known anywhere. Even the websites listed on Google's search results list or another search engine are not sure to be trusted. The service provider does not have time to check those sites for you.
It can be said that in the past time, security companies in the world have made great contributions in 'masking' many fraudulent sales promotion pages.
Often online scammers put a lot of links to their website on search engines along with great discount offers in the hope of pulling more and more people into their websites. Links of this type will often send users to websites that contain forms that require users to fill in information about the card's owner name, number, expiration date and CVV number. After the user provides all of the above information, they will not get anything but only an error page along with instructions they send money by post. But in fact they have lost their ownership of their payment card, losing their money.
That same scam but now phishing - or the way online scammers fake reputable companies send emails to customers with content containing a link where they must also enter The same information as mentioned above. The measure has completely changed.
So users should always be cautious so look for reliable and well-known online shopping websites. Be careful with offers that offer discounts that are too good.
