The holiday shopping season is officially upon us, but it also means so are scammers, who prey on the most vulnerable. 

United Hebrew of New Rochelle brought in security experts to help residents at Willow Towers Assisted Living learn some tips to avoid getting ripped off by scams.

"The bottom line is don't respond to ads, don't respond to emails, and don't respond to text messages," said Gavin Matranga, security director of Ridgewood Savings. 

Other warnings included never buy gift cards, money orders or send cash, or send any bank information, just because an email or caller says so.

"If that happens right away disconnect computer, disconnect the call, let your bank know," says Matranga.

There are ways to know if a website is the real deal, including a padlock icon next to the URL and if there's an S after HTTP.

If you happen to click on a link or provide information you shouldn't have and realize after the fact, don't be embarrassed. Instead, make sure you say something and inform your bank.
