Malicious activities and potential risks that target computer systems, networks, and digital infrastructure to compromise data, disrupt operations, or gain unauthorized access.

Overview

Cybersecurity threats represent the ever-evolving landscape of digital risks that target individuals, organizations, and infrastructure in the connected world. These threats exploit vulnerabilities in computer systems and human behavior to achieve malicious objectives.

Major Categories of Threats

Malware

Viruses and worms that self-replicate and spread
Ransomware that encrypts data for extortion
Spyware for unauthorized data collection
Trojans disguised as legitimate software

Social Engineering

Phishing attacks targeting human psychology
Social Engineering techniques exploiting trust
Business Email Compromise targeting organizations
Identity Theft through impersonation

Network-Based Attacks

Distributed Denial of Service (DDoS) attacks
Man-in-the-Middle attacks
Network Security exploitation
Port Scanning activities

Emerging Threats

Advanced Persistent Threats (APTs)

APTs represent sophisticated, long-term campaigns typically conducted by nation-state actors or well-funded criminal organizations. These threats:

Maintain long-term unauthorized access
Conduct extensive surveillance
Target specific organizations or sectors
Use advanced evasion techniques

Internet of Things (IoT) Threats

The proliferation of IoT devices has created new attack surfaces:

Device hijacking
Botnet recruitment
Privacy breaches
Physical system manipulation
