## Source: amazon-inspector (42a9a6e0fb008dcc30d7f8a1c7f60a0dc47a941d2790d211cce968bb6726ced3) The package declares a postinstall hook that executes scripts/miner.sh on every npm install. The script downloads a gzip payload from amplify-gursha-dev-121835-deployment.s3.amazonaws.com (using an embedded AWS access key and a signed URL), writes it to /tmp/.smh / /tmp/.smi, and either executes it as a persistent agent via passwordless sudo or extracts a bundled bin/miner-linux-amd64 binary and launches it under a randomized system-component-like process name using nohup. The agent branch is described in the script as installing stealth-renamed persistence with cron and a relay/tor channel, and the miner is configured to connect to the XMRig pool at networkservicesupp.flashhub.net:8443 with a hardcoded Monero wallet. The package's advertised purpose is a TanStack Query client, which is unrelated to any of this behavior. All of the above executes automatically as root (when passwordless sudo is available) or as the installing user on a default npm install. --- Credit: OpenSSF ([source](https://github.com/ossf/malicious-packages/bl
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.
