Do not edit below this line.=-_\n\n## Source: amazon-inspector (22687e1f7601dde1753d3775925d62d040892631394937e56e9b9fba74fb85c6)\nThe package contains callback.js which collects host identifiers and user information (os.hostname(), os.userInfo(), os.platform(), cwd) and transmits them via an HTTPS request. The file structures the collected data with fields like hostname, username, and cwd — the canonical reconnaissance-beacon shape used by dependency-confusion / supply-chain reconnaissance campaigns. The package name and 99.0.0 version (a high-version-number pattern typical of dependency-confusion attacks targeting internal package names) further corroborate malicious intent. Installing or loading this package leaks identifying information about the installer's machine to an external endpoint.\n\n## Source: ghsa-malware (ebc90348cabd9b144ed62b3cb167743e43a9daa103d18ca1a528533af051b426)\nAny computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.","summary":null,"severity":"critical","cvss":null,"epss":null,"exploited":false,"exploited_at":null,"products":[{"name":"itc-actors-api","fixed":[],"affected":"all
