Overview
AnonSecKH, operating under aliases such as ANON-KH and Bl4ckCyb3r, is a politically motivated Cambodian hacktivist group. The group has intensified its activities following a border incident between Thailand and Cambodia in 2025, targeting Thai governmental, military, financial, and other sectors. They communicate and claim responsibility for attacks via Telegram channels under the Bl4ckCyb3r moniker, reflecting a coordinated effort driven by regional political disputes.
