MEDIUM

Why flagged The package downloads and installs a prebuilt binary tarball from hb.bizmrg.com, which is VK's own object storage (Mail.ru Group / VK Cloud Solutions S3-compatible storage, 'hb' = Hot Box). This is the official distribution host for VK Teams — the teams.vk.com product is distributed via this CDN. However, from a packaging security standpoint, this is still a prebuilt binary from a vendor-controlled CDN rather than a source build, and the host is not immediately recognizable as 'official' without domain knowledge. The sha256sum is pinned, which mitigates substitution risk. The binary is installed to /opt and executed directly. This is a legitimate vendor binary package (similar to google-chrome-bin, slack-bin, etc.) distributed via the vendor's own storage infrastructure, not a third-party or personal host. The medium rating is borderline — this pattern is standard for proprietary app AUR packages — but the non-obvious host name and prebuilt binary execution justify keeping it at medium rather than clean.

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, …).
