Phishing is an attempt at obtaining your information such as usernames, passwords, and credit card numbers. Phishing attempts are mostly done through email. The phisher puts bogus links in an email that looks legit. When you click on them instead of going to the website you think you’re going to, you have just launched a script that will pull every username, password, website visited, and even your candy crush high score (not really) from the cache files on your computer. Before you realize what has happened there’s money missing off the dresser, and your daughter’s knocked up. I seen it a hundred times. (RIP Farley) Don’t get too worried though, you still have to initiate the script on your end in order for this to work whether it’s clicking a link in an email or visiting a malicious site. One thing you can do if you get a suspicious email is hover over the link and see what url shows (usually at the bottom of your browser). Take a look at this screen shot from an Apple ID phishing email I received. I have to admit, the email is setup very well I actually clicked on the link thinking someone had gotten into my Apple account and I needed to reset my password. I realized this wasn’t the case when the url that opened wasn’t anything to do with Apple at all and immediately shutdown the computer I was on. I reset ALL of my passwords on another computer starting with my Apple ID and email password. If you don’t have a second computer to handle the situation like I did at least reboot your system before resetting your passwords and start with your Apple ID and email passwords. I would then run a scan with whatever antivirus/malware/spyware program you are using.
