Cyber Threats 2025 in Mexico: Analysis of the Most Common Types of Attacks on Medium and Large Enterprises

Introduction

In Mexico, the advancement of digital transformation has been key to the growth of medium and large enterprises. However, this technological dependence has brought with it an increasingly sophisticated wave of cyber threats.

In recent years, the country has reported a considerable increase in incidents related to cyberattacks, affecting not only operations and digital assets but also the reputation and continuity of entire businesses.

At DITESA, we have conducted an in-depth analysis of the most common incidents in 2024 and projections for 2025, combining public reports, industry statistics, and internal data gathered in cybersecurity audits with Mexican companies.

The goal of this report is to provide clarity and preparedness. Because understanding threats is the first step to protecting oneself from them.

Main Cyber Threats in Mexico

Based on audits conducted by the DITESA team and data from cybersecurity institutions such as the National Guard, AMECE, and INAI, we detected that the following five types of attacks account for more than 90% of the incidents reported by medium and large companies in Mexico.

This statistical photograph evidences a reality: the cost of a cyberattack in Mexico is not only economic but also strategic. Sectors such as banking, healthcare, and manufacturing are constant targets, and often, without a clear defense plan.

Detailed Analysis of Cyber Threats in Mexico

1. Ransomware

The ransomware continues to be the most frequent and devastating threat to companies in Mexico in 2025. This type of attack consists of hijacking computer systems, encrypting all data and demanding payment (usually in cryptocurrencies) to restore access.

58% of Mexican companies that have suffered a ransomware attack decide to pay the ransom. However, only 35% manage to recover all their data.

Most Vulnerable Sectors:

• Finance

• Healthcare

• Education and Government

How to protect against ransomware?

• Offline and cloud backups

• Network segmentation and updates

• Employee training and clear protocols

2. Phishing

The phishing remains one of the most effective threats. Fake emails or messages trick employees into providing passwords or confidential information.

🔍 DITESA Fact:

1 in 3 Mexican employees falls for a phishing attempt if they have not received specific cybersecurity training.

How to protect against phishing?

🔍 DITESA Fact:

Retail and digital banking companies in Mexico are the most affected, with average losses of $600,000 MXN for each hour of downtime.

How to protect against DDoS attacks?

• Traffic mitigation services (CDN, advanced firewalls)

• Automated scalability in the face of suspicious spikes

4. Credential Theft

One of the most silent and dangerous attacks. The attacker gains internal access, often undetected, and compromises critical systems.

How to prevent it?

• Multi-factor authentication (MFA)

• Good password practices and access control

• Credential management tools

This type of malicious software is specially designed to compromise a company or sector. It is common in manufacturing, telecommunications, and critical services.

🔍 DITESA Fact:

In Mexico, customized malware grew by 22% annually, mainly affecting critical infrastructure.

How to protect against it?

• EDR/XDR solutions

• Network segmentation and behavior monitoring

• Rapid incident response

Which Sectors Are Most Affected in Mexico?

These five sectors concentrate almost all the attacks analyzed by DITESA. They are industries with high digital exposure and often, without advanced defense protocols.
