Description

NEODYMIUM is an activity group that conducted a campaign in May 2016 and has heavily targeted Turkish victims. The group has demonstrated similarity to another activity group called PROMETHIUM due to overlapping victim and campaign characteristics. (Citation: Microsoft NEODYMIUM Dec 2016) (Citation: Microsoft SIR Vol 21) NEODYMIUM is reportedly associated closely with BlackOasis operations, but evidence that the group names are aliases has not been identified.
