Code is also prepared to alter MarkOfTheWeb, start as admin and run the executable, but in analyzed versions this behavior was not triggered in any existing code path. The downloading will happen e.g. on starting the declared command line.\n\nRemote executables are standalone applications or installators, including ClickOnce installators. However, in the analysis attempts, none of them showed clear malicious behavior, in most cases crashing during the analysis. Captured network traffic shows communication with the remote server and likely expects the URL of the next stage, which was not delivered from the server. Additionally, the code embeds a separate path for execution on non-Windows machines. It attempts to execute a remote script, but in analyzed versions, the domain used is already suspended and not reachable. \n\nIn newer packages the remote code is another downloader, which then downloads a PyInstaller-packed executable that just calls back home but has no more functionality.\n\n\n---\n\nCategory: MALICIOUS - The campaign has clearly malicious intent, like infostealers.\n\n\nCampaign: 2026-02-magichat\n\n\nReasons (based on the campaign):\n\n\n - Downloads and executes a remote executable.\n\n\n - other\n\n\n - typosquatting\n","affected":[{"package":{"ecosystem":"PyPI","name":"polyclawd"},"versions":["1.1.0"]}],"references":[{"type":"EVIDENCE","url":"https://tria.ge/260212-z9ndmabs3b"},{"type":"EVIDENCE","url":"https://www.virustotal.com/gui/file/703439f496bded646bb01b62d2cec96f713346a5e38249cdcab4b4840ea56aa9/detection"},{"type":"EVIDENCE","url":"https://app.any.run/tasks/6c406e3e-5a9b-4019-8427-8be8b30e284a"},{"type":"EVIDENCE","url":"https://tria.ge/260213-22j3cah18b/behavioral1"},{"type":"WEB","url":"https://bad-packages.kam193.eu/pypi/package/polyclawd"},{"type":"WEB","url":"https://www.getsafety.com/blog-posts/magicwolf"}],"credits":[{"name":"Kamil Mańkowski (kam193)","type":"REPORTER","contact":["https://github.com/kam193","https://bad-packages.kam193.eu/"]}],"database_specific":{"iocs":{"domains":["doc-sendapplication.com","updatedappython.com"],"ips":["45.150.34.209"],"urls":["https://www.dropbox.com/scl/fi/8g8j2g6ceuj12loonrxpu/Installer.exe?rlkey=9pi7bsdb31jlgxmntwde4j54h&st=3t69etqf&dl=1","https://www.dropbox.com/scl/fi/itjqck6r0eivh655ijau9/DocSend.application?rlkey=gmbotpa64r8gqtbwiyo4wlfys&st=k0zrfnxe&dl=1","http://myghibligenerator.com/curl/bb4b22014136fa4bd8b47449b7d6032780033e7cbfb104c1f7f61214c602987c","https://updatedappython.com/api/rest.php","http://45.150.34.209/api/","http://45.150.34.209/vbs/","https://updatedappython.com/Inst.exe"]},"malicious-packages-origins":[{"source":"kam193","sha256":"1f994af0e1b17c0d30e950a5aef9a45d8e34f6f59ab45fadddb05b340ed5cdad","import_time":"2026-02-17T00:35:10.195580661Z","id":"pypi/2026-02-magichat/polyclawd","modified_time":"2026-02-16T23:40:13.326459Z","versions":["1.1.0"]},{"source":"kam193","sha256":"d7977b1bddaa22bd2d38f8a5d7f8161446d860a204bcc3b8248a41dba5cb91d3","import_time":"2026-02-26T09:49:02.32712237Z","id":"pypi/2026-02-magichat/polyclawd","modified_time":"2026-02-16T23:40:13.326459Z","versions":["1.1.0"]}]}}
