MEDIUM

Why flagged This PKGBUILD downloads a prebuilt binary .deb from softwaredownload.futunn.com, which is the official Futu (富途) software download host — a legitimate Hong Kong/US-listed brokerage's trading application. The domain is plausible as an official vendor CDN. However, sha256sums='SKIP' means there is no integrity verification of the downloaded binary, so any compromise or substitution of the file on the CDN would go undetected. The package installs a setuid chrome-sandbox (chmod 4755) and executes a prebuilt proprietary binary directly from /opt/FTNN/Launch. This is a classic medium-risk pattern: the source host appears legitimate, but the lack of checksum combined with executing a prebuilt binary means a supply-chain compromise would be undetectable. Not high (no evidence of malice, host is plausible official vendor), but genuinely medium due to SKIP checksum on an executed binary.

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, …).
