The Valuation Explosion: From $7.5B to $18BFluidstack is currently in advanced talks to secure a $1 billion funding round that would value the AI infrastructure startup at $18 billion. This represents a more than doubling of its valuation from the previous round in December, which reportedly raised around $700 million at a $7.5 billion valuation. The potential lead investor for this new round is Jane Street, a major trading firm expanding into venture capital.Previous Round Details: Led by Situational Awareness, an AGI-focused fund founded by former OpenAI researcher Leopold Aschenbrenner.Supporters: The round was backed by the Collison brothers from Stripe, former GitHub CEO Nat Friedman, and entrepreneur Daniel Gross.Google's Interest: Reports indicate Google was considering a $100 million contribution to the round in February.The Anthropic Partnership: A $50 Billion Bet on InfrastructureThe primary driver behind Fluidstack's skyrocketing valuation is its strategic partnership with Anthropic. In November, Anthropic signed a massive $50 billion deal with Fluidstack to build custom-designed data centers in Texas and New York.Custom Infrastructure: Unlike hyperscalers like AWS or Google Cloud that offer general-purpose computing, Fluidstack builds specialized hardware specifically for AI workloads.Strategic Independence: This deal allows Anthropic to bypass the capacity constraints of public cloud providers and gain greater control over its infrastructure.Market Context: Anthropic primarily relies on AWS and Google Cloud for Claude, but the rapid growth of AI models necessitates bespoke solutions.Strategic Pivot: Relocating HQ and Exiting European ProjectsThe deal with Anthropic has fundamentally altered Fluidstack's global strategy, shifting its focus entirely toward the United States.Headquarters Move: The startup, originally spun out of Oxford and a rising star in Europe, has relocated its headquarters from the U.K. to New York.European Exit: Fluidstack pulled out of a key €10 billion AI project in France to focus exclusively on U.S. opportunities.Client Base: Beyond Anthropic, the company counts Meta, Poolside, Black Forest Labs, and Mistral as key customers.The Future of AI Infrastructure: Specialization Over GeneralizationFluidstack's rapid ascent signals a critical shift in the AI industry. As AI models become more complex and compute-intensive, general-purpose cloud providers are struggling to keep up with demand. The market is increasingly favoring specialized infrastructure providers that can offer bespoke hardware and dedicated capacity, a trend that validates Fluidstack's aggressive expansion strategy.

Anthropic, a leading AI developer, has suffered a significant source code leak of its AI-powered coding assistant, Claude Code. The incident occurred due to "human error" during a software update, which mistakenly included an internal-use file pointing to an archive containing nearly 2,000 files and 500,000 lines of code.The leaked code was quickly copied to the developer platform GitHub, where a post sharing a link to the code garnered over 29 million views. A rewritten version of the source code rapidly became GitHub's fastest-ever downloaded repository. In response, Anthropic issued copyright takedown requests to try to contain the code's spread.Analysis of the leaked code revealed blueprints for a Tamagotchi-esque coding assistant and an always-on AI agent. Anthropic assured that the exposed code did not contain confidential data from Claude, the underlying AI model. However, some experts worry that the leak suggests internal security vulnerabilities within Anthropic, which could be particularly troubling for a company focused on AI safety.The leak could also benefit competitors like OpenAI and Google by providing them with insights into Claude Code's AI system. This incident is the second data leak for Anthropic in recent weeks, following a separate breach that exposed thousands of internal files on publicly accessible systems.The US government has designated Anthropic as a supply chain risk, a designation the company is contesting in court. This latest breach comes at a critical time for Anthropic, as its paid subscriber base continues to grow and its Claude chatbot gains popularity.

The Dual Threat: Coruna and DarkSwordSecurity researchers have identified two distinct but equally dangerous hacking toolkits, Coruna and DarkSword, that have leaked onto the open web. These advanced exploit kits, capable of breaking into iPhones and iPads, were originally developed for high-level government surveillance but are now available for anyone to download.Coruna: Targets iOS 13 through 17.2.1. Linked to Trenchant, a unit within U.S. defense contractor L3Harris, and previously used in Operation Triangulation against Russian targets.DarkSword: Targets iOS 18.4 and 18.7. Leaked on GitHub, making it "plug-and-play" for cybercriminals.The Scale of VulnerabilityThe scale of this exposure is staggering. According to Apple's statistics, nearly one-in-three iPhone and iPad users are still not running the latest software. With over 2.5 billion active devices globally, this implies hundreds of millions of users are susceptible to these attacks.DarkSword is particularly concerning because it targets newer devices running iOS 18.4 and 18.7. Researchers have already tested the leaked code, successfully hacking their own devices to demonstrate the ease of use.From State-Sponsored Espionage to Public ExploitationThis leak marks a dangerous shift in the cybersecurity landscape. Historically, sophisticated tools like Coruna were the domain of state-sponsored actors targeting specific regions, such as the Uyghurs in China or activists in Hong Kong.However, the release of DarkSword represents a move toward indiscriminate cybercrime. The tool is written in web languages like HTML and JavaScript, allowing attackers to launch attacks simply by hosting a malicious website. Victims in China, Malaysia, Turkey, Saudi Arabia, and Ukraine have already been targeted.The Future of Zero-Day WeaponizationThe leak of these tools mirrors the infamous 2017 WannaCry ransomware attack, which was fueled by leaked NSA exploits. Once powerful zero-day vulnerabilities are released into the wild, they are nearly impossible to fully contain.Experts recommend immediate action: users must update to iOS 18.7.6 or iOS 26.3.1. For high-risk individuals, enabling Lockdown Mode remains the most effective defense, as there is currently no public evidence of hackers bypassing its protections.

The Anatomy of the DarkSword LeakSecurity researchers have uncovered a significant escalation in iPhone vulnerabilities following the public release of the DarkSword exploit kit on the code-sharing site GitHub. Unlike sophisticated zero-days that require specialized knowledge to deploy, the leaked files are uncomplicated HTML and JavaScript scripts that can be hosted on a server in a matter of minutes. This accessibility has turned a tool previously associated with state-sponsored actors into a potential weapon for any criminal actor.The toolkit specifically targets iPhones and iPads running older versions of Apple’s operating system, such as iOS 18, which have not yet been updated to the latest iOS software. The code is designed to work "out of the box," meaning no iOS expertise is required to execute the attack. Researchers note that the leaked samples share infrastructure with previous campaigns analyzed by iVerify and Google, indicating a continuity in the threat landscape.The Scale of the VulnerabilityThe implications of this leak are vast, given the sheer number of devices potentially affected. According to Apple’s own data, approximately one-quarter of all iPhone and iPad users are still running older operating systems. With over 2.5 billion active devices globally, this suggests that hundreds of millions of users are currently exposed to the capabilities of DarkSword.Targeted Data: The exploit is capable of exfiltrating forensically relevant files, including contacts, messages, call history, and the iOS keychain (which stores Wi-Fi passwords and secrets).Historical Context: DarkSword was previously alleged to be used by Russian government hackers against Ukrainian targets, linking this new leak to geopolitical cyber warfare.From State-Sponsored to Criminal PlaygroundThe ease with which DarkSword can be repurposed has raised alarms within the cybersecurity community. Matthias Frielingsdorf, co-founder of mobile security startup iVerify, described the situation as "bad" and warned that the tool cannot be contained. The transition of such advanced spyware from a restricted government tool to a public commodity lowers the barrier to entry for cybercriminals.Kimberly Samra of Google and security hobbyist matteyeux have independently confirmed that the leaked code is trivial to use. Matteyeux successfully demonstrated the exploit on an iPad mini running iOS 18, proving that the threat is immediate and actionable for malicious actors.The Future of iOS Security and Lockdown ModeApple has responded by issuing an emergency update on March 11 for devices unable to run recent versions of iOS. The company emphasizes that keeping software up to date is the "single most important thing" for security and notes that devices with updated software are not at risk.Furthermore, Apple highlighted that Lockdown Mode would block these specific attacks. As the industry moves forward, the reliance on software updates and hardening features like Lockdown Mode will become increasingly critical in defending against the commoditization of exploit kits like DarkSword.
