Exploring the REF2731 Intrusion Set

Elastic Security Labs identified REF2731, a five-stage intrusion set that deploys the PARALLAX loader and NETWIRE remote access trojan (RAT). The campaign chains these tools together across its attack stages.

Why it matters: Defenders tracking PARALLAX and NETWIRE activity should correlate findings with REF2731 tactics to identify and disrupt the full infection chain.
