A police department in Maine is warning the public against a text message-based coronavirus scam.

Cops in the Maine port town of Thomaston have posted a photo on their Facebook page of a text message sent from an Indiana area code warning the recipient that they need to self-isolate — along with a phony link.

“Someone who came in contact with you has tested positive or has shown symptoms for COVID-19 & recommends you self-isolate/get-tested,” the text message reads.

The alert is not from an official agency and officers from the department have told residents not to click through to the link, which police believe could be a phishing scam to grab victims’ personal information

“If you receive a text message like the one pictured, DO NOT click the link!” the department wrote on Facebook earlier this week. “It is not a message from any official agency. It is however a gateway for bad actors to find their way into your world.”

“The virus is not the only invisible enemy,” police said. “Be vigilant against all threats!”

The department’s message follow advisories from the Better Business Bureau on a host of new scams linked to the virus.

A common scam involves emails and texts that claim to be from the government, and which tell recipients they need to take an “online coronavirus test” in order to receive stimulus relief.

The BBB advises against clicking any link contained in an unsolicited or unverified message.

“As the COVID-19 pandemic spreads, so does uncertainty and fear: two elements that con artists thrive on,” the bureau wrote on its website.
