Why flagged

This PKGBUILD downloads a prebuilt proprietary Electron binary (.deb) from 's7-releases.stacher-cloud.com', which is a project-specific subdomain rather than a well-known official distribution channel (e.g., GitHub releases). The binary is executed directly after extraction. A sha256sum is provided, which mitigates substitution attacks at the point of download, but does not address the risk of the upstream host serving a malicious binary in the first place (the hash would need to be updated per release). The host 'stacher-cloud.com' appears to be the project's own release infrastructure for Stacher (stacher.io), so this is not a random personal host — it is the vendor's own CDN/release server. This is a common pattern for proprietary AUR packages (e.g., similar to how Slack, Discord, etc. are packaged). The main concern is that 'stacher-cloud.com' is not a widely audited infrastructure, and the package installs a closed-source Electron app binary. This is a genuine medium-level supply-chain concern (unofficial/project-specific binary host, closed-source executed code), but not clearly malicious. No piracy or broken flags apply.

Triggered rules
