MEDIUM

Why flagged

Installs a prebuilt binary .deb from a subdomain (squawker-vpn.vm.tryhackme.com) that, while plausibly TryHackMe's own infrastructure, is an unofficial VM/CDN subdomain rather than a canonical release channel, making the artifact unverifiable and swappable; the checksum is present which mitigates but does not eliminate the risk of a silently replaced 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, …).
