Ukraine's national postal operator Ukrposhta confirmed on 25 June that an overnight "hostile cyberattack" on its IT systems disrupted its mobile app and digital services, with engineers restoring functionality through the day ([The Record, 2026-06-25](https://therecord.media/ukraine-state-postal-operator-reports-disruption); [New Voice of Ukraine, 2026-06-25](https://english.nv.ua/business/cyberattack-disrupts-ukrposhta-app-and-digital-services-50619276.html)). A pro-Russian group styling itself the "IT Army of Russia" — distinct from Ukraine's civilian IT Army — separately claimed it had breached Ukrposhta infrastructure weeks earlier and exfiltrated a user database; Recorded Future News states it could not independently verify that claim, and Ukrposhta has not confirmed any data compromise. Treat the exfiltration as an unverified leak-site-style assertion until the operator says otherwise.

**Defender takeaway:** the pattern — public service disruption timed to a hacktivist data-theft claim — is the recurring playbook against European postal, logistics and other citizen-facing public operators. The hardening lesson is structural: keep internet-facing app/API tiers segmented from back-end customer databases so a front-end outage cannot be parlayed into (or conflated with) a data-store compromise.
