Using an unordered list, summarize the following article with between 4 and 8 key points. Anthropic on Wednesday confirmed it is investigating a claim that a small group of people gained access to Mythos. It was in response to a Bloomberg report that said users in a private forum managed to gain access to the model without the normal permissions.
While no malicious activity has been confirmed at this stage, it speaks to wider cybersecurity concerns over just how vulnerable systems can be if AI technology falls into the wrong hands.
Alongside this, the AI company responsible for Claude’s newly announced Project Glasswing has rocked the technology industry recently for its ability to identify uncovered software vulnerabilities.
The company’s decision to restrict access to the powerful Claude Mythos model has sparked fears over how dangerous the technology could be in the wrong hands.
Explaining Mythos and its impact
Mythos is a powerful AI model that represents serious potential threats to an organisation’s cybersecurity. Anthropic explained that its ability to identify unknown flaws in IT systems could enable cybercriminals, or threat actors, to exploit these vulnerabilities.
Speaking on its announcement, Anthropic said Project Glasswing was a starting point.
“No one organisation can solve these cybersecurity problems alone: frontier AI developers, other software companies, security researchers, open-source maintainers and governments across the world all have essential roles to play,” the company explained. “The work of defending the world’s cyber infrastructure might take years … For cyber defenders to come out ahead, we need to act now.”
Mythos has already detected flaws in every major operating system and web browser – even finding one software bug that was 27 years old, Anthropic shared at the start of the month. The company said it would be partnering with technology leaders, including Amazon, Apple, Broadcom, Cisco, Nvidia and Microsoft, among others, to secure their own software with a preview version of the model.
Large US banks were also given initial access; with Anthropic sharing it would soon roll out Mythos to European banks to test the technology. However, its decision not to release the model to the public has prompted unease, particularly amid growing concern that next-generation AI models will contribute to accelerating the scale and sophistication of cyberattacks.
“[Mythos] is a wake-up call – reminding us that cyber resilience isn’t just an IT issue, it’s a priority that requires board-level attention,” commented Sujatha S Iyer, head of AI security at Zoho Corp. “We’re entering a phase where attackers can automate reconnaissance, personalise phishing at scale and identify vulnerabilities faster than many organisations can respond.”
To avoid threat actors getting the upper hand, she explained how businesses should move away from reactive security models, as traditional perimeter-based approaches are no long strong enough.
“Threats are becoming more adaptive and intelligent. Instead, organisations need to prioritise continuous monitoring, identity-first security and rapid incident response capabilities that can keep pace with AI-driven threats,” she added.
Unpacking risk
Roughly 40 companies have early access to Mythos under Project Glasswing to test the AI model as part of their cyber defences. While Anthropic has said this is so the industry can benefit from its knowledge, banks and regulators have started to speculate over the impact Mythos could have – and what risks could happen if it fell into the wrong hands.
Mythos was also announced as Anthropic had to mitigate the impact of some of its internal source code for Claude being leaked, on account of human error. Bill Conner, President and CEO of Jitterbit, said this situation emphasises the importance of reliability in AI tools.
“As AI coding tools move from experimental to essential, the standards we hold them have to move with them,” he noted. “For organisations depending on these tools, the underlying question is about reliability, as well as features. Strong products earn trust through consistent execution.”
He added: “That means security, governance, release integrity, and clear AI accountability have to be built in from the start, not added after something goes wrong.”
With finance ministers and banks concerned about the impact of a single AI model, perhaps the Mythos debate suggests that something more sinister is at play. For Nik Kairinos, CEO of RAIDS AI, restricting the release of Mythos is the right decision, but it only buys Anthropic some time.
“We are no longer debating whether frontier AI creates systemic risk. We are watching institutions scramble to catch up to capabilities that are already in the wild,” he explained. “You cannot prevent every zero-day from being found, by AI or otherwise. What you can do is monitor every AI system in your estate for anomalous behaviour, in real time, with a continuous evidence trail.”
He added: “The organisations that instrumented their AI before this week are in a very different position from those still treating governance as an annual audit exercise.”
