Cybercriminals have been taking advantage of single sign-on (SSO) services in their recent smishing (SMS phishing) scam.

Okta’s single sign-on (SSO) service allows users to log in to multiple accounts by using one set of login credentials. Unfortunately, users aren’t the only people who benefit from this service. Cybercriminals are taking advantage of Okta and other SSO services in a recent smishing (SMS phishing) scam.

To start this scam, cybercriminals send you a text message about an important update to one of your organization’s policies. The text message says to tap a link to read the updated policy. If you tap the link, you’ll be taken to a fake Okta login page and prompted to enter your login credentials. Then, the cybercriminals can use your credentials to access your Okta account and other accounts linked through the service. Once they have access, the cybercriminals can steal sensitive information from you and your organization.

Follow the tips below to stay safe from similar scams:

  • Always be cautious of unexpected text messages. While this scam targets Okta users, it could be used with any authentication service.
  • Think before you click! Cyberattacks are designed to catch you off guard and make you act impulsively.
  • Never tap on a link in a text message that you aren’t expecting. Instead, open your internet browser and navigate to the organization’s official website.

Stop, Look, and Think. Don’t be fooled.
