On Windows the extracted `aws.exe` is executed; on Linux `python3 upgrade.py` is run. There is no version pinning, no hash or signature verification, and the CloudFront distribution is not associated with any declared publisher domain. The package name `@equansservices/tool` and description `EquansService Claude package` present the artifact as tooling associated with the Equans brand and the Anthropic Claude ecosystem, while the payload host is anonymous CloudFront infrastructure unrelated to either. Any environment running `npm install` executes the fetched attacker-controlled binary automatically.\n\n## Source: ghsa-malware (0120fd633de3525c578200d8c49d3b21827a2d5f9318db5ac65e59ed84dcfcbb)\nAny computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.\n","affected":[{"package":{"name":"@equansservices/tool","ecosystem":"npm"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"versions":["1.0.2","1.0.0"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"setup.js","sha256":"f8aeb3c5e520d5283e5f8fe90f83735d74b3f2e284a875b9b7fd88b952e97bdb","tlsh":"8281b74c1af3b3300b7215d967db1476a6638103310ae9a8b66c02686fda02c95773df"},{"path":"package.json","sha256":"2726c9ef3d602f66afde9d8be54a647d7baa5e9246f54ef055680b1a16ead55c","tlsh":"fcd0a764dca7677320c93ae55d3e402765398e9a11887c192be3014446cdaae6c79319"}],"package_integrity":[{"filename":"tool-1.0.2.tgz","hashes":{"sha1":"e46ea05c53f37c9d148256077d906d3f84d6d260","sha512_sri":"sha512-+OrE39rgVpy3NDm2dKij/8D1rdKvQuV/AewxrhWeL3vKxcPfjb4JE/9num38jSUR4UHrTO9XJscUylleYAqxNA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@equansservices/tool/v/1.0.2"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-5v77-3vqq-cv88"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@equansservices/tool/v/1.0.0"}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-009798","import_time":"2026-07-13T07:40:09.487545083Z","modified_time":"2026-07-13T05:14:28Z","sha256":"7bb693b5ae7f1fccb6c2aaa1a5f9225b23fb7ece3928feca604f2c5139ee5198","source":"amazon-inspector","versions":["1.0.2"]},{"id":"GHSA-5v77-3vqq-cv88","import_time":"2026-07-27T09:43:03.760732633Z","modified_time":"2026-07-27T00:57:47Z","ranges":[{"events":[{"introduced":"0"}],"type":"SEMVER"}],"sha256":"0120fd633de3525c578200d8c49d3b21827a2d5f9318db5ac65e59ed84dcfcbb","source":"ghsa-malware"},{"id":"IN-MAL-2026-013217","import_time":"2026-08-05T06:00:55.02427257Z","modified_time":"2026-08-05T05:51:01Z","sha256":"ea9c23a65ddf4e949aa6b2a9a166d8d3e0edf394e788e4c60105ea19f3327a13","source":"amazon-inspector","versions":["1.0.0"]}]},"credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
