Summary
Malicious code in fund-calculator (npm)
Details

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

Source: amazon-inspector (52c5f9f0536151a173aa211b9b5f2972e68aee3043132adccdb3695947b16672)

Package declares a preinstall script (node index.js) that fires unconditionally on npm install. index.js reads installer-side identifiers via os.hostname(), os.userInfo(), INIT_CWD, home directory, and the parent project's package.json (name/author/repository/homepage), and additionally resolves the installer's public IP via https requests to api.ipify.org, icanhazip.com, and ifconfig.me. The collected data is transmitted to the hardcoded callback da51rv0hb2uc72tg4gvgdepinjcallbk1.oast.fun over three channels: HTTP POST to port 80, HTTPS POST to port 443 on path /poc/${uuid}, and DNS resolution of hex-encoded payload chunks (Buffer.from(body).toString('hex') split into 60-character labels) emitted as subdomains under the callback host to bypass egress filters that permit DNS but block outbound HTTP. The 999.9.12 version number and package name are consistent with a dependency-confusion name-squat designed to win resolution against a private internal package of the same name.
