No specific software to patch; no KEV or PoC signals.
  • SOC/IR — Plan: The campaign is described as large-scale and targets users of crypto/trading sites; build or tune EDR behavioral rules for in-browser memory injection and anomalous JS execution patterns this quarter. The summary provides no specific IOCs to hunt on immediately.
