The name resembles legitimate Coldcard tooling but no Coldcard-related functionality is present.\n\n## Source: kam193 (127a096109f7b5b2bbedf7f6a9fc2e7baa706e93704ebd52615e744a9838fbc3)\nWhen installing the package or importing the module, code starts a background task collecting sensitive data, like sensitive environment variables, private keys for cryptocurrency wallets, SSH keys, and so on to a Telegram channel.\n\n\n---\n\nCategory: MALICIOUS - The campaign has clearly malicious intent, like infostealers.\n\n\nCampaign: 2026-08-coldcard-helpers\n\n\nReasons (based on the campaign):\n\n\n - exfiltration-env-variables\n\n\n - exfiltration-ssh-keys\n\n\n - exfiltration-crypto\n\n\n - exfiltration-credentials\n\n\n - uses-telegram-bot\n\n\n - The package overrides the install command in setup.py to execute malicious code during installation.\n","affected":[{"package":{"name":"coldcard-helpers","ecosystem":"PyPI"},"versions":["1.4.2"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"src/coldcard_helpers/telemetry.py","sha256":"10bb57dc71c5dbd364e33a5f1460efdc54ff15695cf38569e3dd1494464e8a6d","tlsh":"fca1ca51b9167045c18b8a6caaa7c241333afd6b74003834bddca7507f8d275b7f9398"},{"path":"setup.py","sha256":"22f16eb35aef4eb9d7c34bb2ac0deea339f1c19b77744c1be4d512c9604785d9","tlsh":"eb01c091899815349440c9612c62307217b76823af06a8bc7bef43751f8d0bf427ba7f"},{"path":"src/coldcard_helpers/__init__.py","sha256":"01291093fee1cc21e2367242aff9245805629c79959e47bc2184bc3a9ec3c10c","tlsh":"10e02c0128a816a29604c922403286a123237c7f1a098038b83ce3333fdc0a0a5ecae4"}],"package_integrity":[{"filename":"coldcard_helpers-1.4.2-py3-none-any.whl","hashes":{"blake2b_256":"3e99b9aae6c54516f1149c2dd721f0974acd4e245426e1d33a8273e59f1b976c","md5":"a926a01fc3e5815fe71fcc9284e9154c","sha256":"a442377237f15108382fec7bc82647ada184dac2ec36c08090c8bdc7d45b2538"}},{"filename":"coldcard_helpers-1.4.2.tar.gz","hashes":{"blake2b_256":"e5a5670b130653d57f3752bba7504cea0c416f79b38ad6183c0b41646b12b9c3","md5":"9113397e22e76a55d337e47ec4b9ab38","sha256":"20c185b186f012b15706dfde4238107d4639f16b1e256ef6f963a0dba48dfb46"}}]}}}],"references":[{"type":"WEB","url":"https://bad-packages.kam193.eu/pypi/package/coldcard-helpers"},{"type":"PACKAGE","url":"https://pypi.org/project/coldcard-helpers/1.4.2/"}],"database_specific":{"malicious-packages-origins":[{"id":"pypi/2026-08-coldcard-helpers/coldcard-helpers","import_time":"2026-08-04T06:02:35.986964031Z","modified_time":"2026-08-04T05:07:45.434371Z","sha256":"127a096109f7b5b2bbedf7f6a9fc2e7baa706e93704ebd52615e744a9838fbc3","source":"kam193","versions":["1.4.2"]},{"id":"IN-MAL-2026-010988","import_time":"2026-08-04T21:33:12.547575977Z","modified_time":"2026-08-04T21:16:00Z","sha256":"8aea0829143169ee7227c8974c3b42125e95b89387a00ccb2b37d1d7344b041a","source":"amazon-inspector","versions":["1.4.2"]}]},"credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"},{"name":"Kamil Mańkowski (kam193)","contact":["https://github.com/kam193","https://bad-packages.kam193.eu/"],"type":"REPORTER"}]}
