Advanced Persistent Threats (APT)

What is an APT? 

An Advanced Persistent Threat (APT) is a sophisticated cyberattack where a well-resourced group gains unauthorized access to a network with the objective of exfiltrating sensitive data or performing cyber espionage. APTs are advanced because they often develop custom tools and exploits, and they’re persistent because they can go undetected for a long period of time that allows them to monitor activities and disrupt operations. They are frequently associated with nation-state or highly organized groups, targeting specific industries or sectors and regions. 

Two examples of APTs and APT groups

• Lazarus Group is linked to North Korea as a state-sponsored cyber threat group and is responsible for the WannaCry ransomware (2017) and cryptocurrency ByBit heist.
• APT41 is linked to China as a state-sponsored espionage group with financial-motivated operations using tools like Winnti malware. They target healthcare, telecom, and software supply chains.

What are 5 different objectives of an APT?

An APT campaign may have one or more of the following objectives:

• Espionage – stealing government, corporate, or defense secrets.
  
• Data theft – exfiltrating intellectual property, credentials, or customer information.
  
• Disruption – sabotaging critical infrastructure or business operations.
  
• Financial gain – stealing funds or cryptocurrency, sometimes as part of nation-state funding.
  
• Strategic influence – shaping geopolitical outcomes by undermining trust or spreading disinformation.
