If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4.

The `oast.fun` domain is a public out-of-band interaction service (interactsh) commonly used as a callback collector, so this beacon discloses the installer's machine hostname to a remote third party at install time. The package name `shopify-app-bridge-internal` (unscoped) with version `99.9.9` and an `internal` suffix is the canonical dependency-confusion shape against Shopify's official scoped `@shopify/app-bridge`, designed to be resolved by internal build systems that look up a private dep name against the public registry. Despite the package's self-description as a bug-bounty PoC, the install-time beacon harms any installer that resolves the name.\n\nAny computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.","ecosystems":["npm"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Malicious code in shopify-app-bridge-internal (npm)","id":"MAL-2026-5452","indexable":true,"kev":null,"kind":"malicious","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":[],"package":"shopify-app-bridge-internal","purl":"pkg:npm/shopify-app-bridge-internal","source":"MAL-2026-5452"}],"products":null,"published":"2026-06-09","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"OpenSSF Malicious Packages","prefix":"MAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":null,"url":"https://insights.sbomify.com/MAL-2026-5452/"}
