Tactics, Techniques, and Procedures (TTPs) of Advanced Persistent Threat Groups
The tactics, techniques, and procedures (TTPs) employed by APT groups are critical to understanding how they operate and how you can defend against them. One common tactic is initial access, where attackers gain entry into a target’s network through various means such as phishing emails or exploiting vulnerabilities in software. Once inside, they often establish a foothold by deploying backdoors or other persistent mechanisms that allow them to maintain access even if the initial vulnerability is patched.
After gaining access, APT groups typically engage in lateral movement within the network. This involves navigating through the organization’s systems to gather sensitive information or escalate privileges. You may find it alarming that these groups often use legitimate credentials obtained through social engineering or credential dumping techniques to blend in with normal user activity.
This stealthy approach makes it difficult for security teams to detect malicious behavior until significant damage has been done. For more information on APT groups and their tactics, you can visit the Cybersecurity and Infrastructure Security Agency (CISA) website.
