Financial institutions under false pretenses utilize email simulations to deploy deceptive links, leading to potential fraud.

Tax and Customs Authority (AT) emphasizes that the messages are untrue and advise the public to disregard them.

The Tax and Customs Authority (AT) has issued a warning about fraudulent emails circulating, claiming to be from the tax office. These emails, which are attempts at phishing, contain links to malicious pages that mimic authentication on the Finance Portal.

One of the emails asks the recipient to regularize a supposedly owed value to the AT, while another claims that a pending payment for a tax related to the last fiscal year has been detected. In some cases, the messages are sent in the name of the fraudulent "National Office of Processes" of AT, with email addresses ending in "@santorini.com.co".

To avoid falling victim to these scams, the AT advises citizens not to respond to messages that raise doubts, not to click on links, not to download or open files, and not to provide their credentials for access to the Finance Portal. If you encounter such emails, the AT recommends deleting them immediately.

To find the informative brochure on Information Security provided by the Tax and Customs Authority via their Finance Portal, you should:

1. Visit the official Tax Agency website (Agencia Tributaria) homepage through their Finance Portal at their e-office site [https://sede.agenciatributaria.gob.es/Sede/en_gb/inicio.html](https://sede.agenciatributaria.gob.es/Sede/en_gb/inicio.html). This is the entry point for all tax-related electronic services and informational resources.

2. Look for sections related to assistance and information or security notices. The site offers virtual assistance tools and various document downloads.

3. Explore areas such as "Frequently Asked Questions (INFORMA)", "Electronic registry" or "Submit documentation", or a section dedicated to security and privacy guidance related to tax filings or electronic invoicing (e.g., Immediate Supply of Information - SII).

4. The Tax Agency website is designed to facilitate easy access to such informational materials for taxpayers, so the brochure should be available as a downloadable PDF within one of these categories or under a specific security-related subsection.

If you do not find the brochure immediately on the homepage, you can also use their search function or contact their virtual assistance tools to request the brochure directly.

It's important to note that the AT recently created a second factor of authentication on the Finance Portal, through the association of the mobile phone number. However, be wary of any mobile phone messages claiming to be from the AT about outstanding debts or requiring you to regularize the situation through a link.

Remember, the AT will never ask for sensitive information via email or text message. If you have any doubts, it's always best to contact the AT directly through their official channels to verify the authenticity of any communication.
