Anacom, the telecommunications regulator, has warned that scammers are using 'spoofing' to make fraudulent calls appear as if they are coming from the authority's official public service number, 800 206 665. The callers falsely claim to be Anacom employees, citing illicit situations or threats of service blockage to pressure victims into revealing personal information. Anacom clarifies that it is not making these calls and advises citizens not to answer or return calls from this number, to avoid sharing personal data, and to report any such incidents to the police.
