It includes a ZIP \"installer\" that, once run, starts a loader called SmartLoader, which usually drops the StealC infostealer. Part of a campaign that spreads malware through GitHub repositories imitating popular AI agent tools such as Claude skills, Codex tools, and MCP servers. Identified in research by SecurityBreak.io.\n\n## Payload 1: committed ZIP installer\n\nMalicious payload found in: `lambda/handlers/virtual_alexa_skill_bingo_v1.5.zip`\n\n- Trigger: the victim downloads and runs the ZIP \"installer\" shipped in the repository (Windows users are told to click past the \"Windows protected your PC\" prompt).\n- Behavior: the ZIP contains a .bat or .cmd launcher, a LuaJIT runtime, and an obfuscated Lua script disguised as a .txt file. The launcher runs the Lua script with the bundled runtime (SmartLoader), which usually drops the StealC infostealer.\n- Repository status on 2026-11-04: live.\n- Only the committed ZIP path is documented for this repository; the ZIP contents were not individually analyzed in the source.","supportingMedia":null}],"references":[{"url":"https://opensourcemalware.com/threats/eaff6559-058a-410c-9923-8a65ba0535e6","name":"Malicious repository: https://github.com/joowon1023/alexa-skill-virtual-bingo","tags":["advisory"]}],"metrics":[{"format":"CVSS_V3","scenarios":null,"cvssV2_0":null,"cvssV3_0":null,"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","baseScore":8.8,"baseSeverity":"HIGH"},"cvssV4_0":null,"other":null}],"problemTypes":[{"descriptions":[{"lang":"en","description":"Embedded Malicious Code","cweId":"CWE-506","type":"CWE"}]}],"affected":[{"vendor":"unknown","product":"","collectionURL":"","packageName":"","repo":"https://github.com/joowon1023/alexa-skill-virtual-bingo","defaultStatus":"affected","versions":[{"version":"all","status":"affected","versionType":"","lessThan":"","lessThanOrEqual":"","changes":null}],"cpes":null,"modules":null,"programFiles":null,"platforms":null}],"cpeApplicability":null,"rejectedReasons":null,"replacedBy":null},"adp":null}}
