Cisco Uses OpenAI Models for Machine-Speed Security Defense

Cisco is leveraging OpenAI's frontier AI models, including GPT-6 Astra and the Daybreak Defense Network, to enhance its enterprise security offerings. By combining network telemetry with AI reasoning, Cisco aims to close the gap between vulnerability exploitation and patching. The partnership emphasizes enterprise data privacy, with OpenAI's zero data retention and strict customer data boundaries. Cisco's Chief Product Officer Jeetu Patel highlights the need to defend at machine speed against AI-powered attacks. The collaboration focuses on integrating AI into existing security workflows and addressing challenges in an agentic world, such as protecting agents and detecting unintended behavior.

• Cisco and OpenAI are collaborating to integrate AI models into Cisco's security defenses.
• OpenAI's commitment to zero data retention enables Cisco to deploy AI on sensitive telemetry.
• Cisco's initiatives include Daybreak and GPT-6 Astra to improve vulnerability patching.

Understanding Coherent Optics in AI Data Center Interconnects

This article explains coherent optical technology, which encodes data in light's amplitude, phase, and polarization, enabling transmission over hundreds of kilometers between AI data centers. It contrasts this with intensity modulation with direct detection (IM-DD) used inside data centers, which is limited to about 10 km. Coherent optics uses a local oscillator laser and digital signal processing (DSP) to overcome fiber dispersion and loss, supporting dense wavelength division multiplexing (DWDM). The article covers cost trade-offs, with a 2022 IEEE contribution estimating the coherent DSP costs 10x, lasers 15x, and receiver 20x more than 400G IM-DD modules. It highlights the shift towards coherent pluggables, citing Cignal AI's expectation of revenue growing from $2B in 2025 to $7.5B by 2030. The emerging 'coherent-lite' variant aims to bring coherent technology into campus networks, though volume adoption is not yet widespread.

Railway urges users to revoke keys after cyberattack

Developer platform Railway confirmed a cyberattack that allowed hackers to access and decrypt some customer secrets, including API keys and passwords. The company urged all users to revoke and rotate their credentials, as the breach may have compromised encrypted environment variables. The attack is likely part of a broader campaign targeting AI inference providers, with possible ties to AI distillation attacks. Railway paused builds during investigation but has since restored service. Affected user count and root cause are undisclosed. Railway plans to publish a post-mortem. The incident follows recent warnings from CISA about China-based AI companies conducting large-scale attacks on U.S. firms.

• Railway confirmed a cyberattack allowing hackers to access and decrypt some customer secrets.
• The company urged all users to revoke and rotate API and cloud keys.
• The attack may be part of a broader campaign targeting AI inference providers.
