A sophisticated phishing campaign has been directed at the iCloud app users. Recently, a large group of Apple's clients have been receiving false e-mail messages informing the user that their iCloud accounts have been compromised and need to be reset. In order to do so, the users are advised to click on the attached link.
Upon clicking the link the users are redirected to a fake, phishing page designed to look like a official Apple's website. The users are then asked to enter their Apple ID and password to proceed. Once the login process is complete, the victims are advised to confirm their personal information, including their address, phone number, date of birth and credit card information.
This is more than enough information for identity thieves to steal the user's identity, take control of his or hers bank account as well as any number of other on-line accounts.

Ultimately, knowledge is critical to sidestepping phishing scams. If a person is aware of the possible threat, he or she will be less likely to fall victim. Therefore, in the event someone from Apple support asks you to do something, simply don't do it. Apple company would never contact their clients to say that their accounts has been hacked.
