Spammers and fraudsters often wiggle into our lives through "social engineering," pretending to be someone that we think we know. What are some of the security tricks you've fallen for? Fess up in the comments below.  It's one of the oldest tricks in the book and yet it's so effective. Guess that's why it keeps resurfacing. We've all seen the bad guys dish out a range of schemes over the years, from using nefarious links embedded in an email to, more recently, social media phishing attacks using these same lethal links in Facebook messages and Tweets. As we know, clicking on these links often leads to a request for users to fill out personal information like social security numbers, user names and passwords to bank account information. Sadly, veteran security journalist Bill Brenner, managing editor for CSO, fell for this common scam recently and shared his shame on his blog. He readily admits (well, after he has spent time changing all his passwords) that he should have known better. The takeaway is that even security experts can be fooled. Which means you. So, once again, let me beat the drum - Don't give out your password to anyone! And better still, don't even click on unsolicited links. Shoot a message to the sender to confirm they indeed sent it and want you to click on it. Yes, it's a pain and similar to setting your computer's security levels at a high level, but it could keep your system safe. Just a thought...
