A prominent Iran-linked hacking group, known as Handala, has successfully breached the systems of PSK Wind Technologies, an Israeli defence contractor specializing in command and control systems for air defence. The breach, announced on April 2, is attributed to Handala, which is believed to be a front for the Iran-backed Void Manticore operation1. Handala is known for its sophisticated tactics, including phishing, data theft, and destructive wiper attacks. The breach of PSK Wind Technologies, a developer of integrated systems for defence and critical communications, highlights the evolving nature of cyber attacks originating from Iran. This incident may have significant implications for the global defence industry, particularly in terms of supply-chain security and regulatory oversight. The breach matters to practitioners because it signals a potential shift in Iran's cyber warfare strategy, which could lead to increased scrutiny of defence contractors' cybersecurity posture and downstream effects on the supply chain.
