Claude Security, currently in public beta for Claude Enterprise customers, now runs codebase scans on Mythos 5. The post Anthropic Expands Mythos 5 Access to More Defenders, Unveils $35M Open Source Fund appeared first on SecurityWeek.

Anthropic has announced an expansion of access to its Mythos 5 model for a broader range of cybersecurity defenders. Concurrently, the company has unveiled a new $35 million fund dedicated to supporting open-source initiatives. These developments aim to leverage advanced AI capabilities for security applications and foster innovation within the open-source community.
The expanded access to Mythos 5 is specifically tied to Anthropic's Claude Security offering. This security service, which is currently in public beta, is available to customers utilizing Claude Enterprise. A key function of Claude Security is its ability to perform codebase scans, and these scans are now powered by the Mythos 5 model. This integration suggests an enhancement in the analytical capabilities available for identifying vulnerabilities and security issues within software code.
Codebase scanning tools are designed to automatically analyze source code for common security flaws, potential backdoors, and adherence to secure coding practices. The use of advanced AI models like Mythos 5 in this context implies a move towards more sophisticated detection mechanisms, potentially capable of identifying complex or novel vulnerabilities that might elude traditional static analysis tools. Such AI-driven approaches can learn from vast datasets of code and vulnerabilities, improving their accuracy and reducing false positives over time.
For enterprise customers, integrating such a service into their development lifecycle can provide an additional layer of security assurance. By running automated scans, organizations can identify and remediate security defects earlier in the development process, a practice often referred to as "shift-left" security. This approach typically leads to lower costs and reduced risks compared to discovering vulnerabilities later in the software lifecycle or after deployment.
The $35 million open-source fund represents a significant investment in the broader technology ecosystem. Funds of this nature typically aim to support projects that align with the donor company's strategic interests, such as advancing AI research, improving cybersecurity tools, or fostering specific technological standards. By funding open-source projects, companies can contribute to the development of shared resources and tools that benefit the entire industry, often leading to collaborative innovation and improved security for all.
This dual announcement highlights Anthropic's commitment to both enhancing its commercial security offerings and contributing to the wider cybersecurity and open-source communities. The expansion of Mythos 5 access to more defenders, specifically through Claude Security's codebase scanning capabilities, indicates a strategic focus on practical applications of AI in enterprise security. The accompanying open-source fund underscores a recognition of the importance of community-driven development and shared resources in addressing complex technological challenges, particularly in the rapidly evolving fields of AI and cybersecurity.
A weakness has been identified in Tenda CP3 27.5.57.101. This issue affects some unknown processing of the file Net/NetCheckPing.cpp. This manipulation of the argument interface_name/host causes os command injection. The attack can be initiated remotely.
A security flaw has been discovered in Tenda CP3 27.5.57.101. This vulnerability affects the function SystemAsh of the file Apis/system.c of the component Kylin. The manipulation of the argument AlarmVoiceURL results in os command injection. It is possible to launch the attack remotely.

OpenAI has announced a $1 billion commitment to provide subsidized access to its Daybreak AI cybersecurity tools for under-resourced critical infrastructure defenders. The initiative, named Daybreak for Frontline Defenders, will offer AI models, training, and technical support over the next six months, prioritizing water and wastewater utilities, electric grid operators, and local government entities. This move aims to equip organizations with limited budgets and staff against increasingly sophisticated cyber threats.

Attackers are exploiting a new unpatched vulnerability in Magento Open Source and Adobe Commerce that lets them run malicious code on an online store's server without logging in, Dutch e-commerce security company Sansec said in an advisory published on September 5. Sansec, which discovered the flaw and named it StyleSmuggler, said attacks started on September 4. "Sansec is publishing early
