<p> Have you seen the commercial in which the woman says, &quot;I saw it on the Internet, so it must be true&quot;?</p> <p> Of course, you know better than to believe that. In fact, one of Abraham Lincoln&#39;s most famous quotations warns us not to believe everything we read on the Internet.</p> <p> Variations of that Lincoln &quot;quote&quot; made the rounds on various <a href="">social media sites</a> last year. No matter how many times it was reposted, someone in the comments section would always fall for the joke.</p> <p> If people will believe Abraham Lincoln mentioned the Internet in a speech, imagine how many people will believe something that actually sounds like it could be true.</p> <p> Social media sites have proven useful for sharing recipes, helpful hints and even warnings of dangerous situations.</p> <p> But not every hint or piece of advice is true. In fact, some may even put you at risk.</p> <p> Here are some of the more popular hoaxes making the social media rounds right now.</p> <p> [<a href="">10 Home Security Tips You Haven&#39;t Thought Of</a>]</p>

Reverse your ATM PIN to call police

<p> According to this rumor, all <a href="">automated teller machines</a> have a built-in alarm system that is triggered by typing in your PIN backwards while your card is still in the slot.</p> <p> The machine is said to recognize the backwards number, and will release money but at the same time alert the police.</p> <p> Some versions of the posting say that various banks have verified that this works and suggest everyone pass it on to all of their friends.</p> <p> This hoax is not new &mdash; according to the urban legend-debunking website Snopes, the story first made the rounds in 2006 &mdash; but it is in fact based on a real system called SafetyPIN.</p> <p> However, the banking industry has refused to install the system, and the Federal Trade Commission <a href="">released a document</a> stating that the technology has never been used on American ATMs.</p> <p> The FTC also warned that trying this &quot;safety trick&quot; could end up putting ATM customers at even greater risk during a robbery.</p> <p> [<a href="">Hear That?

Hotel key cards are linked to credit cards

<p> The hotel key card story isn&#39;t so much an intentional urban myth as it is a misunderstanding, according to Robert Siciliano, a Boston-based McAfee online security expert.</p> <p> Hotel key cards have a magnetic strip, just like a <a href="">credit card</a>, that can be encoded with credit card numbers the same way a credit card can.</p> <p> Identity thieves who hack and crack credit card databases will encode any magnetic stripped card, including the readily available hotel keys, with stolen information. This is called &quot;card cloning&quot; and is done every day.</p> <p> &quot;Somewhere along the lines, it is possible law enforcement read the data off a hotel key-cloned card and someone got confused and decided to write and email telling everyone that hotels store personal information on their keys. They don&#39;t,&quot;&nbsp; Siciliano said.&nbsp;</p> <p> [<a href="">Hotel Lock Hack Is Widespread, Easy to Implement</a>]</p>

Facebook privacy warnings

<p> Every time Facebook makes a change, it seems like the privacy warnings begin popping up.</p> <p> For example, now that the new <a href="">Graph Search</a> is available, countless Facebook members are reposting a statement that starts: &quot;DUE TO THE NEW &#39;GRAPH APP&#39; ANYONE ON FACEBOOK (INCLUDING OTHER COUNTRIES) CAN SEE YOUR PICTURES, LIKES, AND COMMENTS. The next 2 weeks I will be posting this, and please once you have done it please post DONE! Those of you who do not keep my information from going out to the public, I will have to DELETE YOU!&quot;</p> <p> The idea is that if your friends don't follow these instructions, hackers will hit your site and have access to your information.</p> <p> Yes, it is possible someone will hack into your site, but it will probably be because of something you have done rather than as a result of poor Facebook security.</p> <p> For example, you may have allowed malware onto your machine, used an easy-to-crack password, forgotten to log off a machine that others use or not properly utilized the privacy settings already available on Facebook.</p> <p> Any time you put personal information on a website, including Facebook, you are at risk of having that information stolen or compromised.</p> <p> The best way to protect yourself is by not revealing too much, rather than by threatening all your friends.</p> <p> [<a href="">11 Facebook Privacy Steps to Take Now</a>]</p>

Rape prevention and protection

<p> A post entitled &quot;Through a Rapist's Eyes&quot; accompanies a chilling photo of what appears to be a woman&#39;s wrists being held to the ground by a man&#39;s hands.</p> <p> The post goes on to explain exactly what a rapist is looking for in a potential victim and how a woman can protect herself.</p> <p> A similar post claims that by dialing certain numbers on your <a href="">cellphone</a> (either #77 or 112), you will automatically be connected to the state police.</p> <p> Although Snopes pointed out that some states do have a system in which #77 will connect you directly to law enforcement, not every state follows it.</p> <p> Every state does use 911, however, and that is universally the best way to contact police or any emergency personnel (and is also the same number of digits as #77).</p> <p> In regards to the &quot;Rapist's Eyes&quot; post, Snopes reminds readers that being aware of your surroundings is always sound advice, because anyone who appears distracted or lost &mdash; no matter what they are wearing, or how they look or what sex they are &mdash; is at risk.</p> <p> [<a href="">The 10 Most Dangerous Women Online</a>]</p>

&#39;Like&#39; for cash

<p> Not all hoaxes put you at risk. Some just make you look a little foolish. Or, perhaps, the only risk involved is making you look money hungry.</p> <p> Two popular hoaxes right now involve Bill Gates and <a href="">lottery winners</a> who claimed mega-millions of dollars. If you like or share the photo of Gates or a lottery winner, you'll receive lots of cash in return.</p> <p> Actually, all you&#39;ll get in return are comments from your friends telling you that this is a hoax. The millionaires and the billionaire aren&#39;t sharing their money with their social media friends.</p> <p> [<a href="">Suckers! A Decade of Successful Internet Scams</a>]</p>
