It is a new name for the pino-testkit (MAL-2026-16484) campaign; the file hashes below match that record's evidence. The package presents itself as an ordinary utility, so the code runs on import or install without the user knowing.","summary":null,"severity":"critical","cvss":null,"epss":null,"exploited":false,"exploited_at":null,"products":[{"name":"@k.vict1999/pino-std-serializers","fixed":[],"affected":"= 7.2.0","ecosystem":"npm"}],"ecosystems":["npm"],"tags":["malicious","package"],"not_affected_if":[],"how_to_check":null,"fix":null,"status":"open","published_at":"2026-10-26T00:00:00+00:00","first_seen_at":"2026-11-05T06:31:44+00:00","triaged_at":"2026-11-05T06:32:52+00:00","updated_at":"2026-11-05T06:32:52+00:00","category":"package","confidence":null,"triage":null,"analyst_status":null,"analyst_note":null,"search":"'-16484':49C '-18677':8A,11A '-2026':7A,10A,48C 'byte':19C 'byte-ident':18C 'campaign':50C 'code':2A,34C,70C 'decod':31C 'evalu':33C 'evid':59C 'file':52C 'hash':53C 'ident':20C 'import':73C 'instal':75C 'k.vict1999/pino-std-serializers':4A,12A,15C 'know':79C 'lib/contract.js':17C 'load':36C 'mal':6A,9A,47C 'malici':1A,13B 'match':55C 'modul':29C 'name':41C 'new':40C 'npm':5A 'obfusc':28C 'ordinari':66C 'packag':14B,61C 'payload':26C 'pino':24C,45C 'pino-testkit':23C,44C 'present':62C 'record':57C 'run':71C 'ship':16C 'testkit':25C,46C 'user':78C 'util':67C 'without':76C","nicknames":[],"mitigations":[],"who_affected":null,"tier":null,"verified":{},"analyst_revisit_at":null,"fix_status":null,"audience":null,"plain_action":null,"pkeys":["pinostdserializers"],"ptokens":["pino","serializers","std","vict1999"],"labels":["critical","malicious","npm","package"],"campaign_type":null,"first_public_at":"2026-10-26T00:00:00+00:00","kev":null,"cvss_vector":null,"cvss_by":null,"poc_count":0,"sources":[{"source":"osv-malicious","external_id":"MAL-2026-18677","url":"https://osv.dev/vulnerability/MAL-2026-18677","severity":"critical","published_at":"2026-10-26T00:00:00+00:00","modified_at":"2026-11-05T05:15:04+00:00","first_seen_at":"2026-11-05T06:31:44+00:00","fetched_at":"2026-11-05T06:31:44+00:00","note":null}],"documents":[],"exploit_sources":[],"notice":"Free to read, with fair use of about 60 pages a minute.
