Patchwork

Patchwork is a cyber espionage group that has been active since at least December 2015. While this group has not been definitively attributed to India, circumstantial evidence suggests that this group may be a pro-Indian or Indian-based entity. Patchwork has targeted industries related to diplomatic and government agencies. Much of the code used by this group was copied and pasted from online forums. Patchwork has also used spear phishing campaigns to target United States think tank groups in March and April of 2018.
