Malicious code in alelo-sdk (npm)

Type: advisorySource: OSV1 source record

--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (4e7ed1d4017e58a9911a0cfee5d1cf8122a2ac28779a36fdf3ef74484f048748) alelo-sdk@99.0.0 ships lifecycle scripts that harvest installer data and POST it to a hardcoded bare-IP endpoint (209.99.185.109) with TLS certificate verification disabled. preinstall.js collects hostname, username, platform, cwd, and the full process.env and sends the JSON to https://209.99.185.109/preinstall. The postinstall path (index.js) additionally reads.env,.npmrc, and parent-directory.env files, executes whoami/id, and POSTs the collected content to https://209.99.185.109/postinstall..npmrc typically contains npm publish tokens and.env files typically contain cloud and API credentials, so any environment where this package is installed (developer workstation or CI) has its secrets extracted. Package metadata (name 'alelo-sdk', version 99.0.0, description 'internal utilities', author 'Alelo Dev Team') is the canonical dependency-confusion shape targeting a private 'alelo' internal scope with an inflated version number.
