LOW

Why flagged The package downloads a prebuilt .deb from Slack's official release domain (slack-edge.com), which is plausibly the project's own infrastructure; despite the non-whitelisted host, this is a standard practice for official binaries and the worst case of a swapped source would be code execution, but the source is verifiable via b2sum and from an official vendor domain.
