“Many trending social media topics that seem like fun games, but can reveal answers to common password retrieval security questions,” the FBI said in a statement. “Fraudsters can leverage this personal information to reset account passwords and gain access to user data and accounts.”

Of particular concern is the trend of posting old graduation photos. Common security questions used to protect accounts often ask about hometowns, schools and high school mascots.

“Many people include the name of their schools, mascots, and graduation years which are also often answers to common password retrieval security questions,” federal law enforcement offiials said. “Other examples include posting a picture of your first car; answering questions about your best friend; providing the name of your first pet; identifying your first concert, favorite restaurant, or favorite teacher; and tagging your mother, which may reveal her maiden name.”

The FBI was encouraging individuals to be “vigilance and (give) careful consideration of sharing too much personal information online.”

Other recent viral personal list posts include all the cars you’ve owned (including makes/model years), favorite athletes, and top 10 favorite television shows.

“What most people forget is that some of these ‘favorite things’ are commonly used passwords or security questions,” the BBB said. “If your social media privacy settings aren’t high, you could be giving valuable information away for anyone to use.
