What Is APT? | A Quick Guide To Advanced Persistent Threats

Advanced Persistent Threats


Advanced Persistent Threats (APTs) are a form of cyber attack used by hackers to gain access to a computer system or network and then remain undetected for an extended period of time. As the name suggests, they are highly sophisticated and require significant technical capabilities in order to be successful.


How do APTs work?

APT attacks usually begin with an initial point of access into a target system or network. Once inside, the attacker is able to install malicious software that allows them to take control of the system and collect data or disrupt operations. The malware can also be used to create backdoors and further extend their reach within the system. Additionally, attackers may use social engineering tactics such as phishing emails or other deceptive methods to gain access.


What makes APT attacks so dangerous?

The main threat from APT attacks is their ability to remain undetected for long periods of time, allowing hackers to collect important data or disrupt operations without being noticed. Additionally, APT attackers can quickly adapt their tactics and toolsets as they learn more about the target system or network. This makes them particularly difficult to defend against since defenders are often unaware of the attack until it is too late.


How To Prevent APT attacks:

There are several steps that organizations can take to protect themselves against APT attacks. These include:

  • Implementing strong authentication and access controls
  • Limiting user privileges to reduce the attack surface
  • Using firewalls, intrusion detection systems, and other security tools 
  • Developing a comprehensive incident response plan
  • Running regular vulnerability scans and patch management procedures
  • Educating employees about the risks of APTs and how to avoid them.

By taking these precautions, organizations can significantly decrease their risk of becoming victims of an APT attack. It is also important for organizations to stay up-to-date on the latest threats so they can ensure their defenses remain effective in protecting against them.



Advanced Persistent Threats (APTs) are a form of cyber attack that require significant technical capabilities in order to be successful and can cause serious damage if left unchecked. It is essential that organizations take steps to protect themselves from these types of attacks and be aware of the signs that an attack may be taking place. Understanding the fundamentals of how APTs work is essential for organizations to be able to effectively defend against them.
