Cyberattacks no longer affect only large corporations. Freelancers, SMEs, educational centers and businesses of any size are constant targets. Knowing the threats is the first step to defend yourself.

Learn about the most frequent threats, how they work and their impact on your business
Fake emails, SMS, calls or QR codes designed to steal credentials, bank data or initiate fraudulent payments. Includes smishing (SMS), vishing (calls) and quishing (malicious QR codes).
Malware that encrypts entire files and systems, demanding a ransom to recover them. Many groups combine encryption with data theft, threatening to publish information if they don't get paid.
Malicious software that steals passwords, session cookies and bank data. Includes infostealers (credential theft), banking trojans (financial fraud) and spyware (activity monitoring).
Impersonation of executives or suppliers to manipulate business payments and transfers. Increasingly use AI-generated deepfakes to clone voices and videos, adding credibility.
Exploitation of passwords leaked in previous breaches, automatically tested against corporate services (email, VPN, ERP). Without MFA, success is likely.
Bot networks (botnets) overwhelm servers with thousands of simultaneous requests to paralyze online services. Particularly affects e-commerce, educational platforms and critical services.
Manipulation through fake support calls, fraudulent WhatsApp messages or supplier impersonation. Uses OSINT (Open Source Intelligence) to build detailed employee profiles and adapt plausible stories. Exploits trust, fear, urgency or authority.
The best defense is a cybersecurity culture, clear protocols and safe channels to report doubts without fear of repercussions.
Compromising a software supplier, cloud service or management tool allows attacking dozens of clients simultaneously. Even patches, minor code libraries or components can become attack vectors. Evaluate supplier security, maintain updated software inventory and monitor changes after important updates.
Trends that have changed the risk map for companies
Massive creation of phishing emails without spelling errors, voice and video deepfakes, and attack scripts tailored to each victim. 87% of organizations consider AI their fastest-growing cyber threat.
Criminal groups rent ready-to-use ransomware kits, allowing even low-tech attackers to launch complex attacks. Democratizes the threat to any SME.
Leaked passwords combined with brute force attacks and credential stuffing to take control of accounts. Without MFA, the risk is critical.
From email to a combination of email, SMS, calls, QR codes, instant messaging and social media. Each channel presents unique detection challenges.
Compromising a supplier allows attacking dozens or hundreds of clients at once. A vulnerability in third-party software can paralyze your entire operation.
Before attacking, they analyze your website, social media, LinkedIn, public leaks. They gather what technologies you use, decision-maker names and internal structure to customize attacks.
Quick reference of the objective, operation and risk level of each threat
| Attack Type | Main Objective | How It Works | Typical Signs | Risk |
|---|---|---|---|---|
| Phishing | Steal credentials, bank data | Very credible messages, cloned websites, malicious SMS/QR | Extreme urgency, account changes, shortened links | CRITICAL |
| Ransomware/RaaS | Kidnap data, demand ransom | Phishing, exposed RDP/VPN, unpatched vulnerabilities | Slow equipment, encrypted files, ransom notes, service outages | CRITICAL |
| Malware | Steal passwords, data, spy | Fake attachments, pirated downloads, fake pop-ups/captchas | Strange pop-ups, unknown apps, slow network, suspicious access | HIGH |
| BEC/CEO Fraud | Manipulate business payments | Impersonation with deepfakes, cloned voice or video | Urgent bank account change, unusual requests | CRITICAL |
| Credential Attacks | Take control of corporate accounts | Leaked passwords tested automatically against corporate services | Multiple login failures, access from unusual countries | HIGH |
| DDoS | Take services offline | Bot networks flood servers with massive requests | Repeated outages, extreme slowness, abnormal traffic spikes | MEDIUM-HIGH |
| Supply Chain | Enter through suppliers | Compromise third-party software/tools you already use | Incidents reported by suppliers, anomalies after updates | HIGH |
| Social Engineering | Trick people for access or info | Psychological manipulation via calls, messages, fake support | Calls asking for codes/access, pressure to bypass procedures | HIGH |
