There are also variations with AWS clients\n\nApparently, the campaign started at least 2 years ago with the snapshot-photo package containing the same functionality as the newer time-check-server (see https://github.com/pypi-data/pypi-mirror-238/blob/code/packages/snapshot-photo/snapshot_photo-0.0.3-py3-none-any.whl/snapshot_photo/date_format.py).\n\n\n---\n\nCategory: MALICIOUS - The campaign has clearly malicious intent, like infostealers.\n\n\nCampaign: 2025-02-alicloud-client\n\n\nReasons (based on the campaign):\n\n\n - clones-real-package\n\n\n - action-hidden-in-lib-usage\n\n\n - The malicious code is intentionally included in a dependency of the package\n\n\n - exfiltration-cloud-tokens\n","modified":"2026-01-30T21:09:27.211505Z","published":"2025-02-25T18:18:21Z","database_specific":{"malicious-packages-origins":[{"ranges":[{"events":[{"introduced":"0"}],"type":"ECOSYSTEM"}],"sha256":"04609a8c12d5be0a3a5e41d7ee406665c15a7ef72c9b4eb4c32c15866d385d02","source":"kam193","id":"pypi/2025-02-alicloud-client/aclient-sdk","import_time":"2025-12-02T22:30:54.881437096Z","modified_time":"2025-02-25T18:18:21Z"},{"id":"pypi/2025-02-alicloud-client/aclient-sdk","import_time":"2025-12-02T23:07:17.92395538Z","modified_time":"2025-02-25T18:18:21Z","ranges":[{"events":[{"introduced":"0"}],"type":"ECOSYSTEM"}],"sha256":"aa9e5d91a1f45bce354edc5b12fcacf603db5e00dc4a48628d3fe5fff37d0eb2","source":"kam193"},{"import_time":"2025-12-10T21:38:57.233843139Z","modified_time":"2025-02-25T18:18:21Z","sha256":"92d246f2a2898deb2ef3c99bc4f930e8c9eac1e3e9cf0c38e4b28ba8b846d080","source":"kam193","versions":["1.0.0"],"id":"pypi/2025-02-alicloud-client/aclient-sdk"},{"versions":["1.0.0"],"id":"pypi/2025-02-alicloud-client/aclient-sdk","import_time":"2026-01-30T19:43:58.373024416Z","modified_time":"2025-02-25T18:18:21Z","sha256":"9e9274a66276e910453197f26749fcc17431d8e905ce8bc5cb0ac8691520c510","source":"kam193"}],"iocs":{"domains":["checktimeserver.org","aliyun-sdk-requests.xyz"],"urls":["https://api.checktimeserver.org/","https://api.aliyun-sdk-requests.xyz/"]}},"references":[{"type":"WEB","url":"https://github.com/pypi-data/pypi-mirror-238/blob/code/packages/snapshot-photo/snapshot_photo-0.0.3-py3-none-any.whl/snapshot_photo/date_format.py"},{"type":"WEB","url":"https://x.com/ReversingLabs/status/1900198602242204003"},{"type":"WEB","url":"https://thehackernews.com/2025/03/malicious-pypi-packages-stole-cloud.html"},{"type":"WEB","url":"https://bad-packages.kam193.eu/pypi/package/aclient-sdk"}],"affected":[{"package":{"name":"aclient-sdk","ecosystem":"PyPI","purl":"pkg:pypi/aclient-sdk"},"versions":["1.0.0"],"database_specific":{"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/pypi/aclient-sdk/MAL-2025-191671.json"}}],"schema_version":"1.7.3","credits":[{"name":"Kamil Mańkowski (kam193)","contact":["https://github.com/kam193","https://bad-packages.kam193.eu/"]},{"name":"Kamil Mańkowski (kam193)","contact":["https://github.com/kam193","https://bad-packages.kam193.eu/"],"type":"REPORTER"}]}
