What is capa?

capa is a free, open-source tool created by Mandiant’s FLARE team that helps you automatically identify the capabilities of executable files. It's used by malware analysts to quickly determine if a program can do things like communicate over a network, modify Windows services, or hide from security programs—all without needing to dive deep into the code yourself[1][2][3].
