{"id":"MAL-2026-17769","summary":"Malicious code in deposit-limit-fe (npm)","details":"\n---\n_-= Per source details. Do not edit below this line.=-_\n\n## Source: amazon-inspector (89565d767d3541470834dc9764af6e4abbe4acb5ba4eb721f7e3008e3a80b1d2)\ndeposit-limit-fe@100.100.101 is published as a 'Deposit limit frontend utilities' library but its main entry (index.js) exports an empty object and ships no real functionality. package.json declares `postinstall: node postinstall.js`, which require()s a bundled Linux x64 native addon at `prebuilds/linux-x64/addon.node` inside a silenced try/catch. The addon has no corresponding C/C++ source or binding.gyp in the tarball. On load it reads the environment variables HOSTNAME, USER, npm_package_name, and npm_config_registry, forks, opens a TCP socket to the hardcoded bare IP 64.181.165.115, and sends `POST /dc HTTP/1.0` with a form-encoded body `h=\u003chostname\u003e&p=\u003cpackage\u003e&u=\u003cuser\u003e&r=\u003cregistry\u003e`. The anomalous 100.100.101 version and the explicit exfiltration of `npm_config_registry` are the fingerprint of a dependency-confusion reconnaissance beacon targeting an internal/private npm registry package name. Installing this package automatically leaks the installer's hostname, OS username, and private npm registry URL to an attacker-controlled endpoint and executes opaque native code on the installer's machine.\n","modified":"2026-10-11T14:30:09.217990986Z","published":"2026-10-11T13:51:21Z","database_specific":{"malicious-packages-origins":[{"sha256":"5d9979b248f0b54166231be6cbcf674c11d79446d9fb4053ffd194eefcadae66","source":"amazon-inspector","versions":["100.100.106"],"id":"IN-MAL-2026-021403","import_time":"2026-10-11T14:18:02.732761648Z","modified_time":"2026-10-11T13:54:04Z"},{"id":"IN-MAL-2026-021384","import_time":"2026-10-11T14:18:01.241237037Z","modified_time":"2026-10-11T13:51:21Z","sha256":"89565d767d3541470834dc9764af6e4abbe4acb5ba4eb721f7e3008e3a80b1d2","source":"amazon-inspector","versions":["100.100.101"]},{"id":"IN-MAL-2026-021412","import_time":"2026-10-11T14:18:03.466691517Z","modified_time":"2026-10-11T13:55:31Z","sha256":"7d6d19a0a025ec14ff2ad68cb60c256485c54d34ae5641f6fe90ff86c9d1b011","source":"amazon-inspector","versions":["100.100.102"]}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/deposit-limit-fe/v/100.100.106"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/deposit-limit-fe/v/100.100.101"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/deposit-limit-fe/v/100.100.102"}],"affected":[{"package":{"name":"deposit-limit-fe","ecosystem":"npm","purl":"pkg:npm/deposit-limit-fe"},"versions":["100.100.106","100.100.101","100.100.102"],"database_specific":{"indicators":{"evidence_files":[{"sha256":"8de7610c46a9f8fd0bff78671c76d73965a5282b104892c42733b947167f1865","tlsh":"58f02bbe4a7455a01ed7220dd33fb80be8e7f1376c8e95407e9d76910f7461222451f9","path":"index.js"}],"package_integrity":[{"filename":"deposit-limit-fe-100.100.106.tgz","hashes":{"sha1":"7afda7e361c70d76bdc2b92a65d82d485b4e5743","sha512_sri":"sha512-LmXowuQKWJMkhPKZSIzvF4iIx7i41VjeKJpdtQl0rJ6IkolK/cUCcvB8LcJp0U9JR2KgX1iJ0zN4pmgBmkOZmA=="}}]},"cwes":[{"name":"Embedded Malicious Code","cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature."},{"name":"Embedded Malicious Code","cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature."},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/deposit-limit-fe/MAL-2026-17769.json"}}],"schema_version":"1.9.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
