-
Address mungin
-
Virus hoax
-
Spam
-
Email harvesting
-
Phishing
E
Correct answer
Explanation
Phishing is the attempt to acquire sensitive information such as usernames, passwords, and credit card details (and sometimes, indirectly, money) by masquerading as a trustworthy entity in an electronic communication.
-
Chain e-mail
-
Email encryption
-
Email authentication
-
Email Spoofing
-
Hushmail
D
Correct answer
Explanation
E-mail spoofing refers to forging an e-mail header to make it appear, as if it came from somewhere or someone other than the actual source. Email spoofing is the creation of email messages with a forged sender address - something, which is simple to do because the core protocols do not authenticate.
