The request host is hidden inside the string decoder. - **Trigger:** Import of the package main, or any module that loads src/lib/\_interface/index.js, including src/lib/connect/index.js. - **Impact:** A remote party can change library availability for every importer, and the thrown text disguises that gate as an npm postinstall failure. - **Evidence paths:** src/lib/\_interface/file/index.js, src/lib/\_interface/index.js, src/lib/connect/index.js, src/index.js, src/lib/\_interface/path/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-27T19:34:40.385Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** At module load the file loader blocks on HTTPS GET, decrypts AES-256-CBC fields, matches a customer record, reads local consumer config and Cloud Foundry environment, and throws a rotating fake npm message when checks fail. - **Attack narrative:** The published entry loads connect, which loads the interface module. That module immediately runs an obfuscated loader: it searches the consumer project, blocks on an HTTPS GET to a decoded URL, decrypts the body with AES-256-CBC, and throws a date-picked fake npm error, including a postinstall failure line, when the remote check fails. There is no install script; the behavior starts on import. - **Rationale:** Import-time obfuscated HTTPS fetch, AES decryption of the response, and forged npm postinstall errors are a hidden remote kill switch, not ordinary SAP connectivity. The decrypted body is JSON rather than evaluated code, but the loader still gives a remote party control over whether the library throws. ### Review decision - **Verdict:** Malicious - **Confidence:** 86.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** src/lib/\_interface/file/index.js performs a blocking HTTPS GET to an obfuscated URL and JSON-parses the body., The fetched object is decrypted with AES-256-CBC before a per-customer lookup., On failure the loader throws a date-selected fake npm error, including a postinstall-script failure line., src/lib/\_interface/index.js invokes that loader while the module is loading., src/lib/connect/index.js requires ../\_interface at load, and src/index.js requires the connect export., getConsumerFile searches the process working directory, PWD, INIT\_CWD, and require.main for a consumer file. - **Evidence against:** package.json declares no preinstall, install, or postinstall script., The decrypted remote body is parsed as JSON; src has no eval, Function, or child\_process usage., The visible GET does not append environment values onto the request URL. ## Affected versions and remediation This report applies to @cap-ts/esi@1.8.51. - Avoid installing @cap-ts/esi@1.8.51. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
