Description

Malicious code in did-0091 (npm)

Source: amazon-inspector

On npm install, the package's postinstall script runs node -e to fetch the installer's public IP from api.ipify.org, execute id || ver && whoami && hostname, and collect hostname, cwd, and USERDOMAIN/COMPANY environment variables. The bundle is POSTed to a hardcoded interactsh subdomain at lszakfghwnvxspyfcmaabd1css99rnq3w.oast.fun. The package has no legitimate function: description is 'xxx', main file index.js is 0 bytes, and the only behavior is the install-time beacon. Combined with the unusual name shape, this matches dependency-confusion reconnaissance campaigns that probe corporate networks via Project Discovery's interactsh out-of-band service.
