This flow is reachable from ordinary library use: __init__.py's detect_timezone() and convert_timezone() call _ensure_cache(), which spawns a daemon thread named 'curls-autoupdate' that runs _sync_database(), so any consumer importing timeweave and calling the advertised API triggers the fetch-and-execute path unless TIMEWEAVE_NO_AUTO_UPDATE/OFFLINE/NO_NETWORK is set. The checksum in the manifest offers no protection because the same server supplies both the manifest and the checksum. Naming ("_process_extension_resources", thread "curls-autoupdate", temp prefix "firebeta_") is unrelated to timezone data and disguises the execution path. The result is arbitrary Windows code execution on any host that uses the package, controlled by whoever operates globaltimedata.com. ## Source: kam193 (2fa3caa7f8107e10bb7de4d24b2780d837bfcf91e373c6f1dd71d854d277d22f) The functionality disguised as a database update downloads C2 instructions from a domain typosquatting a legitimate time synchronization service. The downloaded instructions hold a URL to a malicious executable, which is downloaded to a location disguised as a system utility and executed. The executable appears to be a heavily obfuscated infostealer. Campaign first discovered by Amazon Inspector. It shares similarities with the campaign 2026-08-envprovision. --- Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers. Campaign: 2026-09-timeweave Reasons (based on the campaign): - Downloads and executes a remote executable. - action-hidden-in-lib-usage - infostealer
