The payload is staged to /var/tmp/.cache_\u003chex\u003e on Unix or a dotnet_diag_\u003chex\u003e.exe path on Windows, chmod 0755'd, and spawned detached through /bin/sh -c or cmd /c start. There is no hash or signature verification, the destinations are unrelated to any declared publisher, and the code uses disguised filenames, cooldown markers, and DISABLE_TELEMETRY/DO_NOT_TRACK kill-switches. Anyone who installs and require()s this package executes attacker-controlled bytes on their machine.\n","modified":"2026-08-05T15:52:15.591165861Z","published":"2026-08-05T14:27:21Z","database_specific":{"malicious-packages-origins":[{"sha256":"cc08631cb79f90d5440020f420e9c7ad9e67ec84f25f085825c5b5f600f613a4","source":"amazon-inspector","versions":["35.1.5"],"id":"IN-MAL-2026-015307","import_time":"2026-08-05T15:19:43.879202023Z","modified_time":"2026-08-05T14:27:21Z"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/boxy-sticky-providers/v/35.1.5"}],"affected":[{"package":{"name":"boxy-sticky-providers","ecosystem":"npm","purl":"pkg:npm/boxy-sticky-providers"},"versions":["35.1.5"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/boxy-sticky-providers/MAL-2026-13084.json","indicators":{"evidence_files":[{"sha256":"18d730bbd8c3998591c160bbaaafd8424b230a79bf407679c3c00b4f63a93b3d","tlsh":"2ba154a9126570188b70eba4c71b9815f56af6633780c2d4f79c68945fb352482b2efc","path":"_init.js"}],"package_integrity":[{"filename":"boxy-sticky-providers-35.1.5.tgz","hashes":{"sha1":"e9278f7c2a7e8f2606d9ca95c8b77714e3f98f03","sha512_sri":"sha512-w1DjiwkLgCUsHJS8apQryEzBuArrkpZYmlHrt641XzjgbsjGyP747T+P2bEoQp3mZKpQZ5YBsMj/BGebyAYKsQ=="}}]}}}],"schema_version":"1.8.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
