-Phishing remains one of the main cyber threats in 2025. Despite advances in cybersecurity, cybercriminals continuously perfect their techniques to deceive users and companies. In this article, we explore what phishing is, how it has evolved, the types that exist, and how you can protect yourself from these attacks.
What is phishing?
Phishing is a type of cyberattack that uses social engineering techniques to deceive victims and obtain confidential information such as login credentials, banking data, or personal information. Attackers impersonate companies, institutions, or trusted individuals to manipulate the user into clicking on a fraudulent link or downloading a malicious file.
Phishing Trends in 2025
Phishing attacks have evolved, and this year we see some concerning trends:
- AI-powered phishing : Cybercriminals use artificial intelligence to create extremely realistic emails and messages. AI bots can maintain real-time conversations to deceive the user.
- Deepfake phishing : the use of deepfake technology allows attackers to impersonate the voice and image of high-ranking company officials to deceive employees and obtain money transfers or critical data.
- Phishing through social networks: criminals use platforms like LinkedIn, Instagram, or WhatsApp to contact victims directly, impersonating colleagues or technical support.
- BEC (Business Email Compromise) attacks : fraudulent emails targeted at companies have become highly sophisticated, with personalized attacks that can cause significant financial losses.
How to Detect a Phishing Attempt
To avoid falling for these traps, it is important to recognize the most common signs:
- Grammatical and spelling errors : Fraudulent emails often contain mistakes that a legitimate company would not make.
- Suspicious email addresses : Check the sender’s address, as it often contains unusual domains.
- Suspicious links : Hover over links to see their actual destination before clicking.
- Urgency messages : Cybercriminals create a sense of urgency to pressure you into acting quickly.
- Request for confidential information
How to Protect Yourself from Phishing
- Enable two-factor authentication (2FA) : Even if your password is stolen, without the second factor, attackers will not be able to access your accounts.
- Use advanced security tools: Cybersecurity solutions with real-time threat detection can help block malicious emails before they reach your inbox .
- Train your employees and collaborators : Cybersecurity training is key to reducing risks in the business environment.
- Always verify the source : If you receive a suspicious email, verify it directly with the purported sender before taking any action .
