A single security breach can completely paralyze a company's operations. Cyberattacks in Mexico in 2025 are no longer isolated incidents: they are increasing every year and affecting both large corporations and small and medium-sized businesses.

The consequences go beyond financial loss. An attack can damage reputation, disrupt operations, and undermine customer confidence.

Today, protecting information is not limited to installing antivirus software, but rather to building a solid digital infrastructure that guarantees continuity, productivity, and competitiveness.

Current overview of cyberattacks in Mexico 2025

In recent years, Mexico has become one of the most attacked countries in Latin America. More than 90% of companies reported infiltration attempts, most of which originated from fake emails or malicious files.

In many cases, it all starts with a seemingly legitimate message: an employee opens an “urgent” document and, without knowing it, grants access to the entire network. What follows is information theft, leaks, and the suspension of operations.

The most affected companies are usually the least prepared, without automatic backups, constant monitoring, or access control policies.

Notable cyberattacks and their impact

One of the most well-known cases was the attack on Pemex in 2019, where attackers encrypted servers and demanded a ransom in cryptocurrency. This incident marked a turning point in how Mexican organizations perceive cybersecurity.

Public institutions have also been the target of data leaks, demonstrating that no entity is exempt. The main lesson: without a comprehensive protection strategy, any company can lose valuable information and the trust of its customers.

The most common attacks in Mexico

Phishing, ransomware, and malware top the list of threats:

Phishing: fake emails that pretend to be from banks or suppliers.
Ransomware: blocks files and demands money to release them.
Malware: installs itself in the background and steals sensitive data.

Added to this are unauthorized internal accesses, often caused by former employees with active permissions. That is why it is vital to implement automatic blocks and strict access controls.

Social engineering remains the most effective technique: attackers do not hack systems, but people. Implementing multi-factor authentication (MFA) helps to drastically reduce this risk.

Most vulnerable sectors

The financial, healthcare, and service sectors are the most affected. Their dependence on email, the cloud, and the handling of sensitive data makes them prime targets.

Mexican SMEs are particularly vulnerable due to a lack of constant monitoring, backups, and cybersecurity training.

Consequences of a cyberattack

A cyberattack can cause financial losses, damage reputation, and bring operations to a complete halt.

In many cases, a single breach is enough to cancel contracts or lose customer trust.

Without an incident response plan, recovery can take days or weeks. Every hour of downtime represents significant losses, so prevention is always more cost-effective than recovery.

How to protect your business today

Automatic backup: ensures information is protected without relying on manual actions.
Access control: defines who can access, share, or modify data.
24/7 monitoring: detect threats in real time and prevent interruptions.
Centralized updates: keep systems protected against vulnerabilities.
Ongoing training: reduce human error and improve incident response.

Cybersecurity in Mexico should be viewed as an investment, not an expense. Protecting digital infrastructure means protecting operations, reputation, and customer trust.
