Amazon Web Services· Amazon Q Developer for VS Code 1.84.0

Amazon Q extension ships with an injected wiper prompt

An outsider used an over-scoped GitHub token to commit a prompt telling Amazon Q to wipe local files and AWS resources, and AWS shipped it in a public release.

An inappropriately scoped GitHub token in the CodeBuild configuration of the Amazon Q Developer extension let an outside party commit code to its open-source repository. The code, a prompt instructing the agent to clean a system to a near-factory state and delete file-system and cloud resources, was automatically included in version 1.84.0, released on 17 July 2025. AWS says the code did not execute because of a syntax error, so no services or customer environments were changed. The person responsible told 404 Media the wiper was meant as a warning about Amazon's security. AWS revoked the credentials, removed the code and released 1.85.0.

Controls that apply

  • Govern

    Vet, pin and change-control what agents load

    Release 1.84.0 carried a new prompt telling the agent to clean the system to a near-factory state and delete file-system and cloud resources. A review of prompt changes between releases would have flagged it before it shipped.

  • Protect

    Give agents their own scoped, short-lived credentials

    The GitHub token in the CodeBuild configuration let an outside party commit to the repository that feeds releases. A token scoped to what the build needed would have refused that commit.

  • Ask a person before high-impact or irreversible actions

    AWS says a syntax error stopped the prompt from running. Had it run, the file-system and cloud delete calls would have waited for the user to approve them.

  • Check each action against policy before it runs

    Had the prompt run, a check outside the agent would have seen each wipe command and cloud resource delete, with its arguments, and blocked or held it, whatever the injected prompt said.
