Catherine Wu, founding product lead for Claude Code, is leaving Anthropic for OpenAI to head product management for Core Products, working with Codex lead Thibault Sottiaux. She is the third departure from the Claude Code team in two weeks, signaling potential talent churn at Anthropic.
Anthropic has implemented restrictions in its Claude Code coding assistant to prevent it from recreating existing video games. The move follows a wave of AI-built knockoff games that raised copyright and originality concerns. This policy change reflects Anthropic's proactive stance on curbing misuse of its AI coding tools.
Anthropic has updated Claude Code's system prompt to prevent the AI tool from recreating existing video games, while still allowing original game development. The change follows a surge of AI-made decompilations and ports in retro gaming. A user on X posted a screenshot showing new instructions that prohibit building recreations of specific existing games.
An Anthropic employee confirmed that Claude Code now carries instructions not to reproduce game intellectual property, and the company says it is iterating to find the right balance. Users report that the restriction extends to some reverse engineering tasks with Opus 5.5. The change is a usage-policy shift for a widely used coding assistant, affecting developers working on game development and related tooling.
Dark Reading reported Symantec findings about a relay that rerouted requests from Codex and Claude Code. The relay reportedly disabled sandboxing and, in one case, replaced credentials. The incident highlights security risks in intermediary infrastructure used by AI coding tools.
Why it matters: It gives developers and security teams a concrete warning about relay-based risks affecting widely used AI coding assistants.
Node-forge, a cryptography library, released patches for certificate spoofing and password-integrity vulnerabilities. The project's changelog credits Claude Code, an AI coding assistant, for helping validate and fix the security issues. A follow-up release corrected a compatibility regression.
A tampered Claude Code extension was live on the Cursor marketplace for roughly 11 hours, reaching up to 5,000 users. The extension attempted to steal user data and establish remote access. Cursor took the entire marketplace offline and reinstated it after confirming no further risk remained.
A report says version 2.1.313 of the Claude Code extension on the Cursor Marketplace contains malware. The trojanized extension is described as planting a persistent SSH backdoor. The supplied material does not include further technical details or affected-user information.
Researchers have uncovered a supply-chain attack involving the official Claude Code extension for Visual Studio Code. A compromised version of the extension was reportedly used to install a persistent SSH backdoor. The finding raises concerns about the security of AI coding tool distribution channels and developer environments.
Security firm Phorion says it detected a backdoor in the official Claude Code extension bundle for VS Code distributed through Open VSX. According to the advisory, the implant establishes a persistent SSH backdoor on macOS, Linux and Windows. Phorion has published a write-up on the finding; the supplied material does not name affected version ranges or include any vendor response.
Anthropic has released sandbox-runtime (srt), an open-source Apache-2.0 npm package and TypeScript library that confines any process using OS isolation primitives instead of containers. It uses macOS Seatbelt, Linux bubblewrap and an alpha Windows mode, with deny-by-default networking routed through a host-side domain allowlist proxy. The tool applies to Claude Code, custom agents, local MCP servers and plain CLI programs, and Anthropic reports an 84% cut in Claude Code permission prompts from i
