Hamdala is a pro-Iranian hacktivist group associated with destructive cyber operations. It has been linked to a March 2026 attack against U.S.-based medical technology company Stryker that reportedly involved breaching corporate systems, stealing large volumes of data, and conducting large-scale data wiping that disrupted operations globally for weeks. The operation was described as retaliatory activity in response to military action involving Iran, the United States, and Israel, indicating a politically motivated and influence-oriented posture rather than financially driven cybercrime. Hamdala is part of the broader ecosystem of Iran-aligned hacktivist activity that surged during regional conflict and is often discussed in the context of blurred boundaries between nominal hacktivist branding and state-aligned cyber operations. High-confidence reporting supports Hamdala’s use of initial access, data exfiltration, destructive post-compromise activity, and disruptive attacks against healthcare-adjacent technology targets in the United States.
