Breaking, new, by me: Iran-backed Hackers Claim Wiper Attack on Medtech Firm Stryker

A hacktivist group with links to Iran's intelligence agencies is claiming responsibility for a data-wiping attack against Stryker, a global medical technology company based in Michigan. News reports out of Ireland, Stryker's largest hub outside of the United States, said the company sent home more than 5,000 workers there today. Meanwhile, a voicemail message at Stryker's main U.S. headquarters says the company is currently experiencing a building emergency.

From the story:

"Wiper attacks usually involve malicious software designed to overwrite any existing data on infected devices. But a trusted source with knowledge of the attack who spoke on condition of anonymity told KrebsOnSecurity the perpetrators in this case appear to have used a Microsoft service called Microsoft Intune to issue a ‘remote wipe’ command against all connected devices."

"Intune is a cloud-based solution built for IT teams to enforce security and data compliance policies, and it provides a single, web-based administrative console to monitor and control devices regardless of location. The Intune connection is supported by this Reddit discussion on the Stryker outage, where several users who claimed to be Stryker employees said they were told to uninstall Intune urgently."

Yet another example of how single-writer can make or break some lock-free algorithms: it's trivial to maintain a lock-free hierarchical bitmap if you set bits top-down and clear bits bottom-up (where a set bit above the bottom level is just a hint, i.e. could be a false positive), but it seems impossible to make this work with multiple writers.

This study about overcoming LLM safety guardrails with "adversarial poetry" now has me thinking about a post-apocalyptic scenario where the only way to access the knowledge and technologies of the old civilisation is through a game of poetic wits with the LLM security systems.
