APT Groups and Their Motivations

Advanced Persistent Threat (APT) groups have different reasons and goals. They can be divided into two main types: nation-state-sponsored APT groups and cybercriminal APT groups.

Nation-State Sponsored APT Groups

Nation-state-sponsored APT groups are supported by governments or spy agencies. Their main goals are to steal secrets and intellectual property. These state-sponsored APT groups aim for sensitive information in the government and military sectors and valuable data in private companies.

Their tactics include sneaking into networks, stealing data, and using advanced malware campaigns.

Cybercriminal APT Groups

Cybercriminal APT groups want to make money. They break into networks to steal sensitive data, like financial info or trade secrets. They sell this data or use it for extortion.

Their attack methods are often very complex. They use malware and network infiltration techniques.

All APT groups are a big threat to companies around the world. Knowing their tactics, targets, and goals is important for developing strong defense strategies against APT cyber attacks.
