MEDIUM

Why flagged The PKGBUILD downloads a prebuilt x86_64 RPM binary from zohocdn.com (Zoho's CDN), which is a legitimate vendor CDN used by Zoho for distributing their desktop applications. Arattai appears to be a Zoho messaging product. However, the checksum is set to SKIP, meaning there is no integrity verification of the downloaded binary. This is a real supply-chain concern: if the CDN is compromised or the URL is silently redirected, an arbitrary binary would be installed without detection. The binary is extracted and installed directly into /opt and /usr, giving it full system access. While zohocdn.com is a plausible official vendor host (not a personal/random host), the absence of any checksum verification elevates this from clean to medium — a tampered or substituted RPM would execute with no integrity check in place.
