Here are two tips to recognize phishing attacks:
1. Look carefully at the email headers: Check the "From" and "To" fields for anything suspicious. While these can be spoofed, they can also be a good first indicator of a suspicious email. Here is how to check the full email headers in Gmail: https://support.google.com/mail/answer/29436?hl=en
2. Hover over links and be sure to read the entire URL: When you hover over a link, notice if the website link is different than the listed URL. Also inspect the entire URL from the first forward slash, back to the left, to see where that link is actually going. For example, http://www.google.com.search.us/query.html is actually going to a server called "search.us," not google.com. Again, this can be spoofed in some cases, but it is a good indicator of how phishing links can appear to be sites we trust.
