In recent weeks there has been an increase in Phishing occurrences in particular through SMS messaging. The Centro Nacional de Ciberseguranca (CNCS) warns that these SMS are sent with sender mobile numbers from several of the national mobile network operators, through the masking of real numbers (phenomenon known as Caller ID spoofing).
The fraudulent messages are mostly simulated bank communications indicating transactions to be made or monetary amounts receivable, indicating a URL to complete this transaction. The submitted URL directs the potential victim to a fraudulent Web page where credentials or other validation information is required for banking services. New variants of this campaign have also simulated SMS from other entities beyond the banking institutions, Such as the retail industry or postal services.
