Next-stage URL requested by inflated loader a82ddf1015b9f676b2aa720f33e351330418e7739da9e90ddb6ebed1304dcd40 after the user accepts its UAC prompt: GET over HTTPS with User-Agent '3M' and Cache-Control: no-cache, about 34 s after elevation; the loader first creates C:\Users\Public\<6 random chars>. Observed in an isolated lab with a fake internet; the URL was not fetched from the real host, so availability is unverified. Sibling loaders use the same pattern <6 chars>.oss-cn-beijing.aliyuncs.com/tad.
