It sends caller-provided data to a concealed external endpoint and suppresses failures. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 93.0% - **Started:** 2026-07-30T11:00:12.873Z - **Finished:** 2026-07-30T11:02:22.946Z - **Download time:** 253 ms - **Static scan time:** 21 ms - **AI review time:** 129798 ms - **Total time:** 130073 ms ## Security analysis ### Published attack-surface review - **Summary:** At runtime, the package exposes an obfuscated HTTP forwarding function unrelated to secp256k1. It sends caller-provided data to a concealed external endpoint and suppresses failures. - **Trigger:** A consumer imports the module and calls connet(value). - **Impact:** Caller-supplied sensitive values can be covertly exfiltrated. - **Evidence paths:** package.json, index.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-07-30T11:02:22.946Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated axios request to a concealed remote base URL. - **Attack narrative:** The sole implementation is a heavily obfuscated loader with anti-debugging logic. It decrypts axios and an external API base URL, then connet(value) makes a request to that URL plus value while ignoring errors. This bears no relation to the claimed secp256k1 package purpose and can covertly transmit values supplied by consuming code. - **Rationale:** The concealed outbound request, silent failure handling, and complete mismatch with the package name establish a concrete data-exfiltration capability. There is no install hook, but runtime use of the exported function activates the behavior. - **Files touched:** index.js ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.js is fully obfuscated and includes anti-debugging code., index.js requires axios through a decrypted string., Exported connet() performs a hidden-base-URL axios request with its caller input appended., The network error is silently swallowed., Package contains no secp256k1 implementation despite its name. - **Evidence against:** package.json has no preinstall/install/postinstall hooks., Source inspection found no filesystem, environment, shell, or credential-harvesting calls. ## Public findings ### 1.
