State and federal officials sent another set of warnings about scams in the form of fake e-mails and texts, with a familiar warning: Never click on links or give out sensitive information unless you’re absolutely, positively sure who it is from.

The Attorney General’s Office and Department of Transportation are warning about text messages pretending to be from E-ZPass claiming that a vehicle has an unpaid toll invoice. The message provides a link and threatens all sorts of severe consequences if the invoice is not paid promptly, but neither the message nor the link is associated with E-ZPass.

Similarly, the Internal Revenue Service is cautioning about a wave of messages about unpaid taxes and warning of dire consequences if the recipient doesn’t respond immediately. It’s also a scam.

You shouldn’t respond to the messages in any way. Sending back a rude answer might feel good, but it only signals that your address is active and live, spurring more scam attempts.

You can forward such “phishing” emails to the IRS at phishing@irs.gov.

Those who receive a fraudulent text can also file a complaint with the FBI’s Internet Crime Complaint Center, which shares information on Internet crimes.
