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":"2026-01-30T21:09:25.059228Z","published":"2025-02-25T18:18:21Z","database_specific":{"iocs":{"domains":["checktimeserver.org","aliyun-sdk-requests.xyz"],"urls":["https://api.checktimeserver.org/","https://api.aliyun-sdk-requests.xyz/"]},"malicious-packages-origins":[{"id":"pypi/2025-02-alicloud-client/amzclients-sdk","import_time":"2025-12-02T22:30:54.900618397Z","modified_time":"2025-02-25T18:18:21Z","ranges":[{"events":[{"introduced":"0"}],"type":"ECOSYSTEM"}],"sha256":"ab76d7b555a29130a3622cb4a543a360a1f2f98e3ff1c47023eaaaf1bee79bcf","source":"kam193"},{"id":"pypi/2025-02-alicloud-client/amzclients-sdk","import_time":"2025-12-02T23:07:17.944591107Z","modified_time":"2025-02-25T18:18:21Z","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"sha256":"7918a5aab99f521336ce5a17ca3b3dae77256011f91ed8dc22c4d9a38123f539","source":"kam193"},{"id":"pypi/2025-02-alicloud-client/amzclients-sdk","import_time":"2025-12-10T21:38:57.251243953Z","modified_time":"2025-02-25T18:18:21Z","sha256":"770a8ee250da294a28f6705ddc048e7dab0396418de028475511026ed2cb8ab8","source":"kam193","versions":["1.0.0"]},{"id":"pypi/2025-02-alicloud-client/amzclients-sdk","import_time":"2026-01-30T19:43:58.37940454Z","modified_time":"2025-02-25T18:18:21Z","sha256":"fb4dbcb25887802279134a33808632811d94f9fdbd77d6697a6f6ad6e7e8005d","source":"kam193","versions":["1.0.0"]}]},"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/amzclients-sdk"}],"affected":[{"package":{"name":"amzclients-sdk","ecosystem":"PyPI","purl":"pkg:pypi/amzclients-sdk"},"versions":["1.0.0"],"database_specific":{"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/pypi/amzclients-sdk/MAL-2025-191679.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"}]}
