Description

On March 24, 2024, Ariza Credit Union in Grenada publicly disclosed a cyberattack that disrupted its computerized systems. The credit union issued a statement that same day confirming the incident and announcing an immediate precautionary shutdown of all systems until at least March 26. This outage affected all operational channels including in-branch banking systems, ATMs, online banking services (specifically referenced as AMIE), and Point of Sale terminals across all physical locations. The institution explicitly stated these services would remain completely unavailable both physically and online during the shutdown period. No technical details regarding the attack vector, intrusion method, or threat actor were disclosed in the public statement.

The credit union emphasized member deposit security assurances while prioritizing restoration efforts, though no specific timeline for full recovery was provided. Operational impacts included complete suspension of transactional capabilities and account access through all standard channels. Ariza Credit Union acknowledged the disruption's severity through a formal apology to members for incurred inconveniences. Restoration work commenced during the outage window, with public communications focusing exclusively on system recovery rather than forensic findings or data compromise details. The institution maintained operational silence regarding potential data exposure, attacker origins, or regulatory notifications beyond the confirmed service interruption timeframe.
