  The Equation Group, an advanced persistent threat identified by Kaspersky's
Research Lab in 2015, was detected during the investigation of the Regin
malware. Attributed to the United States National Security Agency, the Equation
Group's techniques are more advanced than previously discovered threats.
Despite being identified in 2015, detailed studies of their tactics,
techniques, and procedures have been limited. This research examines the
artifacts left by the group, revealing their advanced methodologies and
analyzing the defensive mechanisms embedded within these artifacts designed to
avoid detection by security systems. Additionally, solutions are proposed at
various levels of the digital systems stack to counter the group's
sophisticated attack strategies effectively.
