PHISHING

Phishing is a form of fraud in which the attacker tries to learn information such as login credentials or account information by masquerading as a reputable entity or person in email, IM or other communication channels.

Phishing is popular with cybercriminals, as it is far easier to trick someone into clicking a malicious link in a seemingly legitimate email than trying to break through a computer’s defenses. Although some phishing emails are poorly written and clearly fake, sophisticated cybercriminals employ the techniques of professional marketers to identify the most effective types of messages --  the phishing "hooks" that get the highest "open" or click through rate and the Facebook posts that generate the most likes. Phishing campaigns are often built around the year's major events, holidays and anniversaries, or take advantage of breaking news stories, both true and fictitious.

To make phishing messages look like they are genuinely from a well-known company, they include logos and other identifying information taken directly from that company’s website. The malicious links within the body of the message are designed to make it appear that they go to the spoofed organization. The use of subdomains and misspelled URLs (typosquatting) are common tricks, as is homograph spoofing -- URLs created using different logical characters to read exactly like a trusted domain. Some phishing scams use JavaScript to place a picture of a legitimate URL over a browser’s address bar. The URL revealed by hovering over an embedded link can also be changed by using JavaScript
