Malicious code in @dransay/feature-flags (npm)
GitHub lists this malware advisory for @dransay/feature-flags. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.

@dransay/feature-flags
source listed= 99.0.0
## Source: amazon-inspector (cc545bbb96903ee25218d8cab1a7d116d2ceb1ba64a3c929c79e56a6fc8e0585) @dransay/feature-flags@99.0.0 publishes a scoped name on the public npm registry at an inflated version (99.0.0) designed to win semver resolution against any private internal @dransay/* copy. package.json declares a preinstall hook `node beacon.js`; beacon.js unconditionally performs a DNS lookup and HTTPS GET to the hardcoded interactsh callback host db3klhbi6i9hark1kegg174t38h33b6wt.oast.site on every `npm install`, leaking the installer's public source IP, a timestamp, and confirmation that the scoped name resolved from the public registry to a third-party out-of-band interaction collector. The README self-describes the artifact as a probe of DrAnsay build infrastructure; author self-labeling as research does not change the install-time behavior for any environment whose npm resolves @dransay/* publicly. --- Credit: OpenSSF (source)
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.
05 / Provenance
Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
