Group5 is a threat group with a suspected Iranian nexus, though this attribution is not definite. The group has targeted individuals connected to the Syrian opposition via spearphishing and watering holes, normally using Syrian and Iranian themes. Group5 has used two commonly available remote access tools (RATs), njRAT and NanoCore, as well as an Android RAT, DroidJack. [1]

Standing G0043
Reach is how much of ATT&CK this group touches. Coverage is how well defended each thing it does is, as a median per technique rather than a total — a total would just restate the reach. Each figure is ranked against all 176 ATT&CK groups only where that population actually spreads. Where most of the population shares one value, a percentile would rank the tie instead of the entity, so the raw value is shown and no rank is claimed.
