In recent years, data breaches have become alarmingly frequent, affecting some of the world's leading tech companies and e-commerce platforms. These security violations not only compromise the privacy of millions of people, but also expose their personal data to a range of devastating risks, such as financial fraud, identity theft, and the proliferation of online scams.
What makes this situation even more severe is the ease with which cybercriminals access the stolen information, taking advantage of the lack of adequate protection in some cases. As more and more data is stored on servers and databases, the threat of massive data breaches has become an increasingly relevant issue.
In this context, one of the most recent and concerning incidents has been the breach of over 5 million user records from Amazon Spain, whose personal information is now being sold on the dark web. Although the e-commerce giant Amazon has assured that its systems have not been compromised, the fact that this data is being sold on the black market raises growing concerns about the security of user data and highlights the vulnerabilities of current digital platforms.
This article by ITD Consulting aims to analyze the implications of this security incident at Amazon, both for users and companies, while delving into the possible causes and consequences of the breach. It will also address the preventive and corrective measures that Amazon users can take to protect their personal information, as well as the responsibilities that companies must assume to ensure the security and privacy of the data they manage.
Through this analysis of the cyberattack on Amazon, we aim to shed light on the risks associated with the mass storage of data and how cybercriminals exploit these gaps to carry out targeted attacks on specific individuals. Additionally, the article will explore the implications of the Amazon leak for user trust in online platforms, and how these incidents could alter the relationship between consumers and companies as concern over digital security continues to grow.

What Data from Amazon Spain Was Leaked?
According to HackManac, a portal specialized in tracking data breaches, the compromised information of 5.1 million Amazon Spain users includes several types of sensitive data. This Amazon data is classified as PII (Personally Identifiable Information), which, as the name suggests, can be used to uniquely identify an individual.
The Amazon Spain breach includes a variety of details that, in the wrong hands, can be used to commit fraud or for other more serious purposes such as identity theft or phishing.
1. Full names: Although names are common data, their inclusion in a breach is concerning because when combined with other data (such as ID numbers or addresses), criminals can gain access to more personal information through other means. Often, cybercriminals use a person's full name as a basis to carry out identity theft attacks, making their actions more convincing.
2. National ID numbers: The ID number is a particularly sensitive piece of data. In many countries, this number is used for important procedures, such as applying for loans or opening bank accounts. Its disclosure could open the door to identity theft, which could have serious consequences for the affected user. With this data, criminals can access confidential information in government databases and carry out fraudulent financial transactions.
3. Phone numbers: Cybercriminals can use this information to carry out phone fraud. SIM swapping attacks or using the information to impersonate the victim's identity are some of the crimes that can be perpetrated with this data. Through SIM card swapping, a criminal can gain access to the victim's phone line and, with it, two-factor authentication services, passwords, and more.
4. Postal addresses: Having access to a person's residential address allows criminals to plan more specific frauds, such as theft of goods, or even execute scams where counterfeit products are sent, or physical harm is inflicted on the victim’s home. Information about the geographic location of a person also facilitates targeted attacks in specific areas, such as postal fraud scams.
5. Postal codes and cities: Although these data points might seem less sensitive on their own, when combined with other personal details, they allow fraudsters to further personalize their attacks, increasing the likelihood of successful scams. Identity theft calls that mention specific details about a person's locality or neighborhood can be much more convincing. For example, a fraudster may make a user believe that a local service or product is legitimate, when in reality, it is a scam.
6. Email addresses: Emails are commonly used in phishing campaigns. Criminals can send malicious messages posing as legitimate companies, such as Amazon, and trick users into entering their credentials or even banking details. Moreover, email data, when combined with other data, can provide access to other linked services.
The fact that this information from Amazon Spain has been leaked underscores how critical it is for companies to securely handle their customers' personal data. In a digital environment where data is the most valuable asset, companies like Amazon have the responsibility to implement adequate security measures to protect this information.

How Did the Data Get Leaked? Origin of the Leak at Amazon and Possible Causes
The main mystery in this case is how the data from Amazon Spain ended up in the hands of a cybercriminal, and more specifically, whether this leak was the result of an internal breach within Amazon or if the data was obtained through an associated company or external provider. Amazon Spain has denied any intrusion into its systems, which leaves open the possibility that the data was extracted from an external source or a service provider that had access to users' personal information. Several theories attempt to explain the breach:
Leak from an External Provider: One plausible hypothesis is that the leak did not come directly from Amazon, but from an associated company, such as a customer service provider or a third-party platform linked to Amazon. Such breaches in external providers have occurred in other similar incidents. In 2023, Ring, another company under the Amazon conglomerate, suffered a leak following a ransomware attack targeting its providers.
These types of incidents are particularly difficult to prevent, as large companies like Amazon rely on an extensive network of partners and providers who have access to their internal information. In these cases, the security breach can originate from a partner with weaker protection measures than those of the parent company.
Attacks Targeting Intermediary Companies: If the data came from an intermediary company handling Amazon users' information, attackers could have accessed these records without needing to breach Amazon’s internal systems. In this sense, many cybercriminals are looking for vulnerabilities in the digital supply chain, i.e., companies that provide complementary services to large tech platforms. Attackers often exploit the relationship between these companies and their access to internal systems to leak sensitive data.
Security Failures at Amazon: Although Amazon has denied a direct intrusion, it cannot be ruled out that there was a vulnerability in its security systems. Large tech platforms, such as Amazon, are constant targets of cyberattacks due to the vast amount of personal data they manage.
Companies like Amazon must conduct continuous security assessments to ensure their systems are protected against potential vulnerabilities. Even if Amazon may not have been directly responsible, its systems must be maintained at a consistent level of security, both in terms of infrastructure and software.
Selling Data on the Dark Web: A Marketplace for Stolen Information
The dark web is a hidden online space, accessible only through specific technologies, such as Tor, where illegal transactions take place under no supervision. It is in this environment where cybercriminals buy and sell stolen data. In this case, "Vaquilla" is using this platform to sell the 5.1 million records of Amazon Spain users.
The fact that this data from Amazon Spain is being sold on the dark web is alarming for several reasons. First, the ease with which transactions occur on these platforms facilitates the continuous flow of stolen information. The dark web functions as a black market where cybercriminals can acquire tools, services, and personal data without being easily detected. This network is constantly expanding, with new players joining daily.
What Implications Does This Have for Users? The fact that Amazon’s data is on the black market means that cybercriminals can use it to carry out various types of attacks:
Advanced Phishing: With email addresses, phone numbers, and other personal details, cybercriminals can further customize fraudulent emails, which increases the likelihood of the attack’s success. This level of personalization makes victims much more likely to fall for the scam.
Identity Theft: Using information like ID numbers, full names, and postal addresses can enable criminals to open accounts in victims' names, make fraudulent transactions, and ultimately damage their credit history.
Financial Scams: The compromised data can be used to conduct online scams, such as loan applications or product purchases in the victims’ names.
Security Measures Amazon Spain Users Should Implement
Although Amazon has stated that it has not suffered a direct intrusion into its systems, users of Amazon Spain should take additional measures to protect themselves from the risks resulting from the leak. Here are some key recommendations for Amazon users:
- Change Passwords and Use Strong Passwords: While Amazon has not confirmed that its systems were hacked, it is recommended that users change their passwords immediately, especially if the same password is used across multiple platforms. A strong password should contain a combination of letters, numbers, and symbols.
- Enable Two-Factor Authentication (2FA): Two-factor authentication is an additional layer of security that requires a second factor, such as a code sent to the mobile phone, to access the Amazon account. This adds an extra level of protection against any unauthorized access attempts.
- Stay Alert for Suspicious Communications: Amazon users should be especially vigilant about any communication, whether by email or phone, asking for personal information or appearing to come from Amazon. It is essential to always verify the authenticity of the source before providing any personal data.
- Report Any Suspicious Activity: If Amazon users receive suspicious phone calls or emails that seem to impersonate Amazon, they should immediately report the incident to the relevant authorities and Amazon's technical support so the case can be investigated.

This incident at Amazon Spain highlights one of the biggest concerns in the digital age: the protection of personal data on large platforms. Although Amazon has denied that the breach came from its internal systems, the fact that this data is for sale on the dark web underscores the importance of implementing robust security measures and ensuring data protection not only within companies but also across their providers and business partners.
In the long term, cybersecurity education, improvements in data management protocols, and the implementation of advanced technologies are essential to protect users from incidents like this one at Amazon Spain. Companies like Amazon must commit to ensuring their users' privacy and security and collaborate closely with authorities to prevent personal information from being used for malicious purposes.
This case from Amazon Spain also reflects an urgent need for collaboration between companies, governments, and users to build a more robust security infrastructure that prevents data theft and abuse. Amazon users must be aware of the risks, take preventive measures, and stay informed about how to protect themselves from the ever-evolving cyber threats in an increasingly digital world.
