MEDIUM

Why flagged The PKGBUILD downloads a prebuilt Windows executable (GM ARCADE.exe) from an Aliyun OSS bucket (xiaou-game.oss-cn-hangzhou.aliyuncs.com), which is a personal/unofficial cloud storage host rather than an official vendor release channel. The checksum is 'SKIP', so there is no integrity verification. The binary is then installed to /opt and executed via Wine. This is a genuine supply-chain concern: the OSS bucket owner could replace the zip at any time with a malicious payload, and there is no way to detect substitution. The pattern (prebuilt executable from unofficial personal host + no checksum) meets the medium threshold. It is not clearly malicious, but the risk is real and non-trivial.

Triggered rules

MEDIUM source=() URL on a non-standard host source_untrusted_domain

One or more source=() URLs point to a host outside the trusted allowlist (github.com, gitlab.com, codeberg.org, pypi.org, …).
