Vendors Beware: Scammers posing as Commonwealth agents with EFT forms

The Office of the Comptroller (CTR) and the Operational Services Division (OSD) have been made aware of a scam targeting vendors to the Commonwealth of Massachusetts, or companies bidding on contracting opportunities with Commonwealth departments.

In many of these cases, vendors are purporting to represent the Commonwealth of Massachusetts, and are requesting that the vendor submit an Electronic Funds Transfer (EFT) Authorization Form with banking information if they want payments to continue.

Vendors are reminded that, if asked to submit banking information, they should contact a trusted source at the department with which they are doing business via phone or in person (not by email) to verify that the request is legitimate.

If you have been targeted in this way, please forward that email to comptroller.info@mass.gov.
