Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. 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. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-5790/ (Markdown: https://insights.sbomify.com/MAL-2026-5790/index.md)","id":"MAL-2026-5790","markdown":"https://insights.sbomify.com/MAL-2026-5790/index.md","name":"MAL-2026-5790","record":{"aliases":["GHSA-2m3g-j8c8-hx83"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"ldpbootstrap-jquery ships and executes an obfuscated Windows PowerShell payload as part of its documented usage. The package contains dist/ps1-stub.enc.hex, an 8KB opaque hex-encoded blob, and dist/bootstrap.js decrypts it with a hardcoded XOR key (f633ffeeffbbc09da9f2b477e1183294), writes the decrypted PS1 to %LOCALAPPDATA%\\Landpage\\\u003cps1FileName\u003e, and invokes it via `powershell.exe -NoProfile -ExecutionPolicy RemoteSigned -WindowStyle Hidden -File \u003cpath\u003e` — explicitly bypassing execution policy and hiding the window. bootstrap.js also fetches a session-specific PS1 over plain HTTP from a consumer-configured apiBase (README example: http://192.168.1.143:3001) using MSXML2.ServerXMLHTTP with session/fingerprint headers, then writes and executes it via the same hidden PowerShell flow. The README explicitly documents AV evasion as a design goal, referencing docs/HTA-AV-HYGIENE.md and describing per-session XOR key derivation in an HTA context for MSI delivery. The shipped encrypted blob, hardcoded decryption key, hidden-window/policy-bypass PowerShell execution, and author-documented anti-virus evasion together constitute malware-distribution infrastructure. Although the harmful flow is invoked through the package's API rather than auto-running on `npm install` or `require()`, any developer using the package as documented will execute attacker-shaped, AV-evading PowerShell on Windows endpoints.\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 ldpbootstrap-jquery (npm)","id":"MAL-2026-5790","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":"ldpbootstrap-jquery","purl":"pkg:npm/ldpbootstrap-jquery","source":"MAL-2026-5790"}],"products":null,"published":"2026-06-15","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-2026-5790/"}
