  • Use the business variant and sign a data processing agreement (DPA).
  • Do not enter unnecessary personal data into prompts; anonymise where possible.
  • Enable EU data residency where the provider offers it.
  • Keep a professional in the loop: source code is a trade secret and intellectual property.

9 November 2026Claude Code stores approved commands containing passwords in settings.local.json

If you choose "Yes, and don't ask again" in Claude Code, the tool saves the command verbatim in .claude/settings.local.json, including passwords or API keys. Apiiro found real secrets in 1,122 of 104,185 public copies on GitHub, including 379 database passwords. Keep the file out of git, use variables for secrets, and replace any keys that have already leaked. source

5 November 2026Flaw in Lockdown Mode patched

Via pop-up windows in the HTML preview of code blocks, an attacker could bypass Lockdown Mode and siphon off your chat history, via a manipulated prompt, GPT or shared chat. OpenAI patched the flaw on 18 September 2026; Check Point published the details on 5 November. Users do not need to do anything. source

November 2 2026Message threads (beta) fall outside Zero Data Retention

With message threads in the Claude API, Anthropic stores the conversation, the system prompt and the tools on the server, encrypted in memory and not on disk, until up to one hour after the last use. The feature does not qualify for Zero Data Retention; your other ZDR agreements still apply. If you work with personal data under ZDR, only enable threads if your DPIA covers it. source

What should I watch out for with AI in IT & software development?
Source code is trade secret and intellectual property. Check whether AI coding assistants store your code or use it for model training (an opt-out or business plan is required). Use on-premises or privacy-compliant variants for sensitive projects. AI-generated code sometimes contains security vulnerabilities or errors, so always have a developer review it, especially production code.
