crossmint-wallets-sdk

Package name impersonates the Crossmint wallet SDK family. Both preinstall.js and index.js import child_process, capture host identifiers (hostname is read on line 7/9 respectively), and POST the collected data via https.request to a hardcoded external endpoint (line 12/23). The preinstall.js path fires automatically on `npm install` before any user code runs, giving the publisher install-time data exfiltration from any developer or build system that installs this package. The combination of child_process + hostname collection + outbound POST in a preinstall lifecycle script, in a package whose name typosquats a known wallet SDK, matches the active-attack credential/reconnaissance exfiltration fingerprint. ## Source: ghsa-malware (87671437bf61440c69244dbb16af87b5f0df48e46b990bf4814be4fdb2001b03) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
