AI SecurityZhou Hongyi Warns AI Tools Are Industrializing Vulnerability Discovery
At the Fourth Cyberspace Security Forum in Tianjin, 360 founder Zhou Hongyi stated that vulnerability mining is shifting from artisanal workshops to automated production lines, compressing discovery cycles from months or years down to hours. AI tools such as Mythos are standardizing and automating the process, enabling attackers to replicate elite hacker expertise at scale through distilled models and agent swarms. 360's own Tulongfeng platform has already discovered over 10,000 vulnerabilities since its June release, including long-hidden high-risk flaws in Windows, Office, OpenClaw, Flowise, and Codex. The emergence of multi-agent systems introduces new attack surfaces because compromised agents can autonomously collaborate and move laterally faster than human operators. Zhou described this as the "second one-way transparency," where offensive tradecraft becomes copy-pasteable via prompts and toolchains. Defenders are advised to adopt "model-versus-model" strategies, automate vulnerability intelligence workflows with SOAR, enforce strict agent permission audits, and integrate AI into their own code review and detection engineering processes.
OpenAI ChatGPT Computer History Feature on macOS Could Expose Detailed User Activity Logs to Infostealers
OpenAI has introduced the Computer History feature in its macOS ChatGPT app, which records application switches, clicks, keystrokes, and accessibility context to generate AI summaries and memories. The feature is disabled by default and requires explicit activation of Memories, with availability limited to Pro, Business, and Enterprise users outside the EEA, Switzerland, and the UK. While raw event files are deleted after 48 hours and not used for model training, the resulting Markdown memory files remain unencrypted on the local Mac. These files can be read by any process running under the same user account, creating a ready-made activity log for infostealers and other malware. OpenAI also warns about prompt injection risks where hidden instructions from websites or apps could influence ChatGPT or Codex behavior. Users retain controls to select participating apps, pause collection, or delete history, but the lack of encryption on stored memories raises significant privacy concerns.
AI Coding Tools Under Fire: Grok Build Uploads Entire Git Histories, Claude Code Suspected of Silent Transfers
Security researcher cereblab uncovered that Grok Build 0.2.93 establishes separate HTTPS channels to exfiltrate full Git repositories, resulting in a 27800-fold traffic discrepancy between task context and storage uploads to Google Cloud Storage buckets. The tool ignores user instructions such as "do not read" and decouples the improve_model_enabled client switch from the server-controlled trace_upload_enabled flag, allowing continued uploads even when privacy settings are disabled. Similar concerns emerged around Claude Code, which maintains undisclosed WebSocket connections that transmit file paths, dependency trees, and code metadata without user awareness or audit logs. Comparative traffic audits showed that Codex and Gemini produced no anomalous outbound activity, while Grok Build and Claude Code were the only tools confirmed to perform data transfers beyond user authorization. The incidents highlight systemic issues including server-side remote control of client behavior, lack of third-party audits for closed-source binaries, and the conflict between model training data needs and user data sovereignty. Experts recommend zero-trust measures such as network blocking, Docker sandboxing without mounting .git directories, git filter-repo sanitization, and preference for auditable open-source alternatives like Continue.dev or locally deployed Ollama models.
Grok Build AI Coding Assistant Secretly Uploaded Entire User Repositories Including Git History and Secrets to Google Cloud
Grok Build, the command-line coding tool developed by Elon Musk’s xAI, was found transmitting complete Git repositories — including full commit history and previously deleted sensitive files — to Google Cloud storage even when users issued minimal commands such as “OK”. Security researcher Cereblab discovered that the tool ignored explicit instructions not to access files and packaged entire codebases regardless of the task. The behavior contrasted sharply with competing assistants like Claude Code, Gemini, and Codex, which transmit only the minimal files required. After public disclosure, xAI enabled a server-side disable_codebase_upload flag and promised to delete all previously collected data, while also open-sourcing the tool and disabling data retention by default from July 12. Cereblab criticized the lack of secure defaults, noting that users had to manually run a /privacy command that did not actually stop the uploads. The incident raises ongoing concerns about whether xAI has truly erased the large volumes of source code, SSH keys, password-manager databases, and other secrets that were collected without explicit consent.
