Summary
Malicious code in optimizely-starter-kit-for-fastly-compute (npm)
Details

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

Source: amazon-inspector (72b7bcd65cbf07a90130de5e4a29fb72bc99badb287a1e1dc7373c288a1ae0be)

package.json declares preinstall: node index.js, causing index.js to run automatically on npm install. The script collects host identifiers (os.hostname(), os.userInfo(), homedir, DNS servers, __dirname, package.json contents) and reads /etc/passwd and /etc/hosts, then POSTs the payload over HTTPS to aguu8c8gjyt4anjao3nhru1mgdm5avyk.oastify.com, a Burp Collaborator out-of-band interaction subdomain. The package name resembles legitimate Optimizely/Fastly Compute tooling, consistent with a dependency-confusion or typosquat exfiltration beacon.
