Intelligence Profile
According to Trend Micro, PeckBirdy is a script-based framework which, while possessing advanced capabilities, is implemented using JScript, an old script language.

This flexibility allowed to use PeckBirdy in various kill chain stages, including being used as a watering-hole control server during the initial attack phase, as a reverse shell server during the lateral movement phase, and as a C&C server during the backdoor phase.
