A Agency for the Technological Reform of the State (ARTE) today warned of the circulation of fraudulent SMS messages that misuse the name of the Digital Mobile Key (CMD), which may induce the provision of personal data or codes.
In a statement, ART points out that “national cybersecurity authorities are monitoring the situation and taking the necessary measures”.
These messages “can present themselves as legitimate communications related to the Digital Mobile Key, seeking to convey confidence to the recipients and to lead them to follow instructions or to access links included in the text”.
In this sense, ART emphasises that it never requests by SMS, e-mail or telephone call “personal data or bank account data”.
ART calls for “priority in the use of digital public services and confirmation of the authenticity of the communications received”.
The entity recommends that “citizens adopt preventive behaviour and maintain a special caution against unexpected messages that request confirmation of data, updating information or conducting procedures through links”.
ART advises citizens to “not click on links included in suspicious SMS” and to “not provide personal data, passwords or authentication codes on pages accessed through such messages”, as well as to “confirm the authenticity of communications through official channels of public services”, among other measures.
If you receive “a suspicious message should ignore it, do not respond, do not click on the links included in it or make any payment without prior confirmation of the legitimacy of the request”.
If you have entered personal data or authentication codes on a suspicious page, “you should act quickly to protect your accounts and contact the official support channels appropriate to the situation,” says ART.
If in doubt, citizens may contact the ART Citizen's Line (210 489 010 or 300 003 990 between 09:00 and 18:00).
