Why flagged

The source is a prebuilt .deb from cdn.dida365.cn, which is the official CDN for Dida365 (the Chinese version of TickTick), a legitimate commercial todo application. This is a standard vendor-hosted binary, not an unofficial or personal host. The sha512sums are pinned, providing integrity verification. The 'yarn add @electron/remote@2.1.3' call fetches a specific pinned version of a well-known, official Electron ecosystem package from the npm registry — this is a common AUR pattern for patching Electron apps to work with system Electron. The version is pinned (2.1.3), reducing supply-chain risk. The overall pattern (extract deb, patch asar to add @electron/remote, repack) is a well-established technique in AUR Electron packaging. No obfuscation, no arbitrary code execution beyond normal build steps, no exfiltration. The main residual concern is that yarn resolves @electron/remote@2.1.3 from npm at build time without a lockfile, but this is a low-severity sloppy practice rather than a genuine supply-chain attack vector given the pinned version.

Triggered rules

Low AI review downgraded a static finding llm_review

The static rules flagged this MEDIUM, but an AI model (anthropic/claude-4.6-sonnet-20260217) reviewed the full PKGBUILD and judged it LOW (confidence 78%): The source is a prebuilt .deb from cdn.dida365.cn, which is the official CDN for Dida365 (the Chinese version of TickTick), a legitimate commercial todo application. This is a standard vendor-hosted binary, not an unofficial or personal host. The sha512sums are pinned, providing integrity verification.

2 higher static findings superseded - not the current verdict (shown for transparency)

Medium npm/yarn/pnpm install of an undeclared external package npm_install_external

Runs `npm/yarn/pnpm install <package>` for a package not in source=(), pulling unpinned, unreviewed code at build time. Severity downgraded: the package declares/looks like a Node.js consumer, where build-time installs are expected.

PKGBUILD:35 yarn add @electron/remote@2.1.3

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, …).

PKGBUILD:16 source=("${_pkgname}_${pkgver}.deb::https://cdn.dida365.cn/download/linux/linux_deb_x64/dida-${pkgver}-amd64.deb"
