The New York City Office of Information Technology Services reminded New Yorkers on Cyber Monday to remain cautious of scams while shopping online.

They recommended shopping only with merchants and websites you know and trust and to make sure the site is secure.

They advised to look for "HTTPS" when making an online purchase. The "s" stands for "secure" and indicates that communication with the web page is encrypted.

Think twice before clicking on email links or pop-up advertisements, they warned.

The ITS also said to refrain from using public computers or Wi-Fi for personal banking or online shopping. Public computers may be compromised with malicious software. Additionally, criminals can intercept traffic on public wireless networks to steal credit card numbers and other confidential information.

Using different passwords for different online accounts, especially for those accounts tied to your financial information, is also advised.

Lastly, the ITS says to consider changing your passwords after the holiday shopping season ends in order to further protect yourself.
