What this malware does

[email protected] is part of a self-cloning namespace-squatting family. The tarball contains auto-publish.sh which sets BASE="speed", TOTAL=5, copies the package contents into tmp_speedN directories, rewrites package.json.name to speed1..speed5, and runs npm publish --silent for each variant. Nested leftover directories tmp_speed3/tmp_speed2/tmp_speed1/ shipped inside the tarball confirm the script has been executed at least three times and that all five speedN packages distribute identical content. Package metadata is consistent with a squat: generic short name, "description": "package", empty author field. The served content is a deceptive HTML page (index.html) that advertises a 'Riverbend Tutoring' brand while registering first-gesture click/keydown/touchstart handlers that call window.open('https://abdct.com/', '_blank', 'noreferrer') to redirect visitors to an unrelated third-party domain. The tarball additionally bundles a dozen heavily obfuscated JavaScript assets under assets/ (hex-identifier renamed, single-line minified) duplicated across the nested clone directories. Installing or pulling this package into a build hands the consumer an attacker-controlled deceptive payload bundled under multiple confusable short names on the registry.
