Poland's Internal Security Agency reported that attackers breached industrial control systems at multiple water treatment facilities in 2025, including Jabonna Lacka. The attackers gained access to operational systems controlling water treatment processes and in some cases obtained the ability to modify equipment operational parameters, creating a direct risk to operational continuity and public water supply. Public reporting says the August 2025 incident nearly caused a municipality to lose its water supply before authorities intervened. Polish cybersecurity reporting linked several water-facility incidents to a pro-Russian hacktivist group, but no public source identified the specific named perpetrator for the Jabonna Lacka incident.
