This Week's Top Five Stories in Cyber
Stryker Cyber Attack: Iranian Threat Actor Claims Revenge
On Day 12 of the US-Israeli war on Iran, the looming threat of an Iranian cyber attack materialised and claimed its first major victim – Stryker.
The global medical technology supplier, headquartered in Michigan, US, was subject to a severe cyber attack which left thousands of employees locked out of accessing critical systems.
“Stryker is experiencing a global network disruption to our Microsoft environment as a result of a cyber attack,” the company said in a statement.
Past midnight on Wednesday, outages struck Stryker, as its devices were wiped clean and the company login page was reportedly defaced with the logo of Tehran-linked cyber persona Handala.
Iran War: The Convergence of Cyber and Kinetic Warfare
An operation as precise as taking out Iran's Supreme Leader would have been almost impossible without cyber and intelligence supremacy.
But these capabilities – which Iran also wields, Europol warns – could have “immediate repercussions” for EU nations in the form of cyber attacks.
Iran still lies in total internet blackout as the war enters day 10, with Netblocks’ data showing connectivity at 1% of regular levels. It has faced hostile cyber activity, including the hacking of its BadeSaba religious calendar app.
The country is also mounting its own cyber campaigns, as Check Point Software notes: “During the ongoing conflict, we identified intensified targeting of IP cameras from two manufacturers starting on 28 February, originating from infrastructure we attribute to Iranian threat actors.”
Google & Wiz: The Age of Cloud-to-Cloud Security at AI Speed
Google has officially finalised its acquisition of Wiz, the cloud and AI security company, in a deal that could reshape the landscape of enterprise cybersecurity.
The deal's completion signals Google Cloud's commitment to bolstering its security capabilities at a time when organisations face an increasingly sophisticated threat landscape.
Thomas Kurian, CEO of Google Cloud, says the acquisition of Wiz adds to Google Cloud's "robust security portfolio as companies across all industries face a growing number of cybersecurity threats".
He adds: "Wiz enables organisations to secure cloud and AI applications by connecting code, cloud and runtime into a single shared context, allowing customers to identify risks, harden environments and protect applications continuously.
Ericsson Data Breach Exposes Third-Party Service Risks
Another high profile data breach has occurred – and the early signs are that third-party service providers are to blame.
Telecommunications giant Ericsson has fallen victim to a breach affecting individuals linked to its US operations following a cyber incident at one of its external service providers.
The company confirmed that certain personal data belonging to employees and customers may have been accessed without authorisation, which could include: names, addresses, social security numbers, driver’s licence numbers, government-issued ID numbers and even financial information.
The incident, which was detected on 28 April 2025, did not involve Ericsson’s internal systems but rather a vendor which, according to Ericsson, noticed a “suspicious event that may have involved potential unauthorised access to certain data on their system”.
Nissan and Arkestro: Securing Automotive Supply Chains
The automotive industry's reliance on complex digital supply chains has created new vulnerabilities that require sophisticated technological responses, with procurement systems increasingly becoming targets for cyber threats.
With supply chain attacks on the rise, automotive manufacturers are recognising that procurement modernisation must address both operational efficiency and cybersecurity resilience simultaneously.
Following high-profile cyber incidents in the sector during 2024 and 2025, Nissan is partnering with Arkestro to strengthen its procurement infrastructure through advanced predictive technology.
Procurement platforms have become attractive targets for threat actors, with higher risks around data breaches, supplier compromise and supply chain infiltration.
