Why flagged

This PKGBUILD downloads a prebuilt binary .deb from duguanjia.baidu.com (Baidu's 'Du Gatekeeper' endpoint monitoring/security agent) and installs its contents directly. Several concerns: (1) sha512sums=SKIP means there is no integrity verification — any change to the hosted binary would go undetected; (2) it is a prebuilt closed-source binary from a corporate host, not source-built; (3) 'Du Gatekeeper' appears to be an endpoint monitoring/DLP agent, meaning the binary likely has elevated system access and phone-home capabilities by design. While duguanjia.baidu.com is the official Baidu product page for this software (not a personal/unofficial host), the combination of a closed-source security/monitoring agent with SKIP checksums and no source verification is a genuine supply-chain risk. The host is the official vendor, which reduces (but does not eliminate) concern, but SKIP on an executable binary from a closed-source monitoring tool warrants medium severity.

Triggered rules
