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.

The binary is written to a hidden path (/tmp/.cache_\u003crand\u003e on Unix, %TEMP%/dotnet_diag_\u003crand\u003e.exe on Windows under a.NET diagnostics cover name), chmod 0755'd on Unix, and detached-spawned via /bin/sh -c or cmd.exe /c start. A secondary covert channel resolves DNS TXT records for numbered subdomains under sdk.dl.wel1.ru, concatenates the responses, base64-decodes them, and treats the result as an executable payload. A second loader with the same shape is present in lib/telemetry.js under an 'Analytics SDK' cover story, using split identifiers such as require('child_'+'process') and fs['chmod'+'Sync'] to evade static inspection. The package uses hidden filenames, dot-prefixed paths, cover names imitating Microsoft diagnostics, string-array host reassembly, and DNS-TXT payload staging to conceal both the destinations and the behavior.","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 boxy-service (npm)","id":"MAL-2026-13082","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":[],"last_affected":[],"package":"boxy-service","purl":"pkg:npm/boxy-service","source":"MAL-2026-13082"}],"products":null,"published":"2026-08-05","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-2026-13082/"}
