The group targets medium to large organizations across various sectors, particularly in the Asia-Pacific region, and has demonstrated a high level of technical maturity and operational discipline. Their activities include systematic compromise of enterprise environments, mass account enumeration, and the use of encrypted channels for data exfiltration.
