Homonym: APT (Appropriate)
APT stands for Advanced Persistent Threat, which refers to a prolonged and targeted cyberattack where an intruder gains access to a network and remains undetected for an extended period. These attacks are often carried out by skilled hackers, sometimes linked to nation-states or organized crime, who aim to steal sensitive information or disrupt operations.
Unlike typical cyberattacks that may be opportunistic, APTs are strategic and methodical. Attackers use various techniques, such as phishing and malware, to infiltrate systems. Once inside, they gather intelligence and maintain a presence, making it challenging for organizations to detect and respond effectively.
