Context
MikeDor is a bespoke implant written in Go and cross-compiled for more than one target. It is publicly attributed as the primary tool of SLIM SPIDER, an eCrime adversary that has been targeting Brazilian financial institutions since at least March 2026. The only public description of the family is cut off at the sentence that would enumerate what it does, so its capabilities, delivery chain and supported platforms are deliberately not asserted here.
