Cyberspionage is the practice of using digital techniques and cyber tools to covertly access, steal, or monitor sensitive information from individuals, corporations, or government entities. Unlike traditional espionage, cyberspionage leverages computer networks, malware, phishing, and other cyberattack methods to infiltrate targets, often remaining undetected for extended periods. The stolen data may include trade secrets, intellectual property, classified government documents, or personal information. Cyberspionage is typically conducted by nation-states, organized crime groups, or other malicious actors seeking competitive, strategic, or political advantage. Defending against cyberspionage requires robust cybersecurity measures and constant vigilance.
