This fires automatically on `npm install`, leaking the installer's OS username to an attacker-controlled out-of-band callback host. The package is otherwise empty of legitimate content. The combination of the @adobesign scope, an implausible 99.9.9 version, and an out-of-band beacon is the canonical dependency-confusion attack shape: the public package is designed to be resolved in place of an internal Adobe Sign package of the same name, and any build that resolves it will beacon the installer's identity to the attacker.\n\n## Source: ossf-package-analysis (89bc395364731dd31b151f421bf94decd4441180ae9fa8e16ae540015c3bdc51)\nThe OpenSSF Package Analysis project identified '@adobesign/as-dev-tools' @ 99.9.10 (npm) as malicious.\n\nIt is considered malicious because:\n\n- The package communicates with a domain associated with malicious activity.\n\n- The package executes one or more commands associated with malicious behavior.\n","affected":[{"package":{"ecosystem":"npm","name":"@adobesign/as-dev-tools"},"versions":["99.9.10","99.9.9"],"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"}],"indicators":{"evidence_files":[{"path":"package.json","sha256":"381c12f3e0b146361b3e2c4f0581c5734a02e59778849c5bf5c4594002aca361","tlsh":"26d02b7f8d308d331bcc135d44365266f5078c4b284ca92996cb1194434d2f1f53795e"}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@adobesign/as-dev-tools/v/99.9.10"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@adobesign/as-dev-tools/v/99.9.9"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]},{"name":"OpenSSF: Package Analysis","type":"FINDER","contact":["https://github.com/ossf/package-analysis","https://openssf.slack.com/channels/package_analysis"]}],"database_specific":{"malicious-packages-origins":[{"source":"ossf-package-analysis","sha256":"89bc395364731dd31b151f421bf94decd4441180ae9fa8e16ae540015c3bdc51","import_time":"2026-07-05T15:30:02.125112709Z","modified_time":"2026-07-05T15:20:44Z","versions":["99.9.10"]},{"source":"ossf-package-analysis","sha256":"bc3c9c46e2d893c8ec87ae68a36569c3561b94fdc6ff9954a02d26bbed847ed6","import_time":"2026-07-05T15:30:02.041037716Z","modified_time":"2026-07-05T15:16:01Z","versions":["99.9.9"]},{"source":"amazon-inspector","sha256":"1762a59d0384b9b8ec626aa449b2af6541c8d90ea278009c3d80892efbd7168c","import_time":"2026-07-08T17:01:30.512787633Z","id":"IN-MAL-2026-008101","modified_time":"2026-07-08T16:25:04Z","versions":["99.9.10"]},{"source":"amazon-inspector","sha256":"6752e4d30c584cb5ca6f67265c983257c1531aa306b47ec00b43ddae83fe2532","import_time":"2026-07-08T17:01:31.053852492Z","id":"IN-MAL-2026-008107","modified_time":"2026-07-08T16:25:54Z","versions":["99.9.9"]}]}}
