Phishing Attack is the most widely used hacking technique in which hacker usually sends an e-mail that appears to come from a bank, or credit card company or ISP — requesting “verification” of information. Usually emails also claims that you have exceeded the storage limit for your mailbox and, therefore, your email account will be closed if you do not click a link to increase your storage capacity. These messages ask for verification of personal information, such as an account number, a password, or a date of birth.

Malware Attack, or “malicious software,” is designed to secretly access your computer, compromise email accounts and steal data. Malware can be introduced into a computer while browsing the internet or opening an email.
