In 2026, advanced persistent threat (APT) attacks are increasingly targeting financial institutions and businesses in Vietnam and the Asian region. Cybersecurity experts from VNPT Cyber Immunity emphasize the need for organizations to adopt a proactive defense strategy against these stealthy and prolonged attacks. They recommend mastering three core layers of intelligence data: Indicators of Compromise (IoC), Indicators of Attack (IoA), and Tactics, Techniques, and Procedures (TTPs) to effectively identify and counter APT campaigns. The experts highlight the importance of continuous monitoring and coordination among IT and business operations teams to minimize damage. The incident response process includes detecting anomalies, gathering evidence, identifying the campaign, assessing the impact, and containing the attack. Businesses are advised to avoid focusing solely on immediate problem resolution and instead seek to understand the attack chain to prevent future incidents.
