Recent and more sophisticated cyber-attacks have increasingly focused on infiltrating organizations by embedding malware or harmful files within web applications and emails. These attacks facilitate the dissemination of malware that often evades detection by standard security measures; thus, they are referred to as Advanced Persistent Threats (APTs). Despite this growing concern, many organizations continue to utilize traditional security approaches, such as antivirus programs, firewalls, and intrusion prevention systems, to counteract evolving malware threats. As a result, numerous organizations find themselves still exposed to these Advanced Persistent Threats. It is well-known that the repercussions of such attacks can lead to significant financial losses due to compromised intellectual property, theft of sensitive information, damage to infrastructure, and operational downtime. To combat these complex threats, AhnLab MDS (Malware Defense System) offers a robust APT protection solution that utilizes a hybrid of on-premise and cloud-based analytics, effectively addressing advanced targeted threats throughout the organization and enhancing overall cybersecurity resilience. Moreover, this comprehensive approach empowers organizations to proactively defend against the ever-changing landscape of cyber threats.
