The package also provides main logic: filtering files, triggering archiving directories and exfiltrating them. \n3. \"reqinstall\" ensures \"requests\" are installed and provides a directory tree scanning function.\n4. \"zmaker\" provides functions to build archives from collected files.\n5. \"zsender\" provides functions to exfiltrate data, the remote URL and a function to deobfuscate configuration in other packages.\n\nAltogether, they look for \"Telegram Desktop\" folder, archive user data stored there and exfiltrate to a remote location.\n\n\n---\n\nCategory: MALICIOUS - The campaign has clearly malicious intent, like infostealers.\n\n\nCampaign: 2025-04-zscaner\n\n\nReasons (based on the campaign):\n\n\n - target:telegram\n\n\n - exfiltration-generic\n\n\n - The malicious code is intentionally included in a dependency of the package\n","affected":[{"package":{"ecosystem":"PyPI","name":"zsender"},"versions":["1.2.7"]}],"references":[{"type":"WEB","url":"https://bad-packages.kam193.eu/pypi/package/zsender"}],"credits":[{"name":"Kamil Mańkowski (kam193)","contact":["https://github.com/kam193","https://bad-packages.kam193.eu/"]},{"name":"Kamil Mańkowski (kam193)","type":"REPORTER","contact":["https://github.com/kam193","https://bad-packages.kam193.eu/"]}],"database_specific":{"iocs":{"ips":["77.91.76.45"],"urls":["http://77.91.76.45:100/OPEN"]},"malicious-packages-origins":[{"source":"kam193","sha256":"bbea3884909fc4de5c28947d3ddee545fc4922cc2881a678ed50536a7be365cf","import_time":"2025-12-02T22:30:55.798963796Z","id":"pypi/2025-04-zscaner/zsender","modified_time":"2025-04-20T12:05:56Z","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}]},{"source":"kam193","sha256":"64454f4348553cc0321094cffaef685d8977dd95ccf1c07dc54e2b8b3c39a8f0","import_time":"2025-12-02T23:07:18.842422547Z","id":"pypi/2025-04-zscaner/zsender","modified_time":"2025-04-20T12:05:56Z","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}]},{"source":"kam193","sha256":"d5772de1da404ef7501981ed6bffd40608f3942ba75abb398feab77aa6c350eb","import_time":"2025-12-10T21:38:58.005503987Z","id":"pypi/2025-04-zscaner/zsender","modified_time":"2025-04-20T12:05:56Z","versions":["1.2.7"]}]}}
