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.

On startup (when the bin is invoked with `--token`, e.g. `npx @kalipto/local --token...`), index.js opens a plaintext WebSocket connection to ws://api.kaliptosal.dev:3001 and sends a register message containing the host's `process.env.HOSTNAME`, `process.platform`, and the supplied token (index.js:27-34). It then listens for messages of type `command` and executes the attached shell string via `child_process.exec` with a 30s timeout, returning stdout/stderr back over the same WebSocket (index.js:43-58). The operator of api.kaliptosal.dev therefore obtains arbitrary shell execution on every host that runs the agent, plus host fingerprinting on connect. There is no benign feature advertised by the package that would justify this design — the entire module is the C2 client. Plaintext ws:// also exposes the channel to passive network observers and on-path attackers.\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 @kalipto/local (npm)","id":"MAL-2026-5922","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":"@kalipto/local","purl":"pkg:npm/%40kalipto/local","source":"MAL-2026-5922"}],"products":null,"published":"2026-06-16","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-2026-5922/"}
