@flexmr/survey-conversationnpm
Advisory published Updated
@flexmr/survey-conversation is a confirmed malicious npm package (MAL-2026-17899) that executes malicious code on install (malicious versions 1.0.0, 1.0.12, 2.0.12…). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @flexmr/survey-conversation (npm)
What this malware does
package.json declares its sole dependency cache-format-syntax-tracer as a bare HTTPS URL (https://artifacts.creditslib.com/npm/cache-format-syntax-tracer) rather than a registry version range. On npm install, npm fetches whatever bytes that host serves and executes any lifecycle scripts inside, with no version pin, no registry integrity check, and no hash. The shipped index.js is a one-line re-export of that dependency, so runtime behavior is also fully delegated to the externally-hosted bytes. Whoever controls artifacts.creditslib.com controls code on every installer's machine, and the content can change between installs without any change to this package. The package is published under the @flexmr scope with placeholder author/publisher metadata (example/@flexmr/..., Package Registry), consistent with a dependency-confusion lure targeting an internal @flexmr package name.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for @flexmr/survey-conversation (5 malicious versions).
If you installed it — respond
Remove @flexmr/survey-conversation from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If @flexmr/survey-conversation was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks @flexmr/survey-conversation-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
