Safety first! See where shortened URLs lead BEFORE you click them! Social-engineering threats are rapidly growing, courtesy of the security vulnerabilities of sites that regularly use abbreviated URLs. Anyone who's read Twitter or Facebook posts is familiar with cryptic URLs such as bitly, tinyurl, and snipurl. Because they're shortened to seemingly random letters, numbers, and characters, you don't know where they're actually taking you. But all too often, we click them anyway.
