Malicious code, or malware, is harmful software—including viruses, worms, and trojans—designed to disrupt, steal, or damage systems. Attackers deploy it via phishing emails, infected downloads, or network vulnerabilities to gain unauthorized access. Beneficiaries range from cybercriminals seeking financial extortion or data theft, to hacktivists and nation-states pursuing espionage or sabotage.
