Overview

As technology continues to evolve, so do the methods used by cybercriminals. In 2025, threat actors are increasingly leveraging artificial intelligence (AI), automation, and supply chain vulnerabilities to launch sophisticated attacks across global organizations. Below is a roundup of the most notable new cyberattack techniques and how Fortinet’s security solutions help defend against them.

Top Emerging Cyberattack Techniques in 2025

AI-Powered Phishing

Cybercriminals now use AI to craft highly convincing phishing emails, messages, and voice calls that mimic natural language and appear personalized—making them harder to detect.

Deepfake-Based Social Engineering

Attackers generate realistic fake videos or voice recordings of executives to manipulate employees into transferring money or disclosing sensitive information.

Living-off-the-Land (LotL) Attacks

Threat actors exploit legitimate tools like PowerShell to conduct malicious activities without installing malware, making detection extremely challenging.

Supply Chain Attacks 2.0

Hackers insert malicious code into third-party software, open-source libraries, or CI/CD pipelines—gaining insider access through trusted vendors.

Adversarial AI Attacks

By feeding misleading input into AI models (e.g., image recognition or fraud detection), attackers cause the system to make incorrect decisions or allow malicious activity.

Cloud-Native Attacks

Exploiting misconfigured cloud environments, API metadata, or container breakout vulnerabilities to gain unauthorized access and control.

Ransomware 3.0

The latest ransomware combines data encryption, data theft, and public extortion—pressuring victims multiple times (e.g., LockBit 3.0 tactics).

API Abuse & Shadow APIs

Attackers exploit poorly managed public APIs or undocumented shadow APIs to inject malicious payloads or extract sensitive data.

Zero-Click Exploits

These attacks require no user interaction—malware is delivered simply through a message, file, or notification.

MFA Fatigue Attacks

By bombarding users with frequent authentication requests, attackers trick victims into unintentionally approving unauthorized access.
