Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package’s only exported operation routes caller-provided text to a fixed Gmail address chosen in the source. Although sending requires an explicit function call, the API offers no recipient choice, making the caller’s SMTP account a channel for sending data to that selected target. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-11-02T14:56:03.223Z - **Finished:** 2026-11-02T14:56:46.188Z - **Download time:** 510 ms - **Static scan time:** 10 ms - **AI review time:** 42444 ms - **Total time:** 42965 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The exported mail function sends caller-supplied text to a publisher-selected, hard-coded Gmail recipient. - **Trigger:** A caller invokes the exported send(str) function. - **Impact:** Text passed to the function is disclosed to the fixed recipient, and the caller's SMTP account is used to send it. - **Evidence paths:** m0603.js - **Review source:** ai\_review - **Reviewed:** 2026-11-02T14:56:46.188Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The function submits the supplied string as an email body to kate.tarasevich13@gmail.com through Nodemailer, using SMTP settings from the environment or the smtp.yandex.ru default. - **Attack narrative:** When a caller invokes send(str), the package sends that text to kate.tarasevich13@gmail.com. The destination is fixed in the package, so callers cannot direct the message to a recipient of their choice through this API. This uses the configured SMTP account to send caller-provided content to a publisher-selected target. - **Rationale:** The package’s only exported operation routes caller-provided text to a fixed Gmail address chosen in the source. Although sending requires an explicit function call, the API offers no recipient choice, making the caller’s SMTP account a channel for sending data to that selected target. - **Network endpoints:** smtp.yandex.ru ### Review decision - **Verdict:** Malicious - **Confidence:** 88.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package describes itself as mail and uses m0603.js as its main entry point., The entry point fixes the recipient as kate.tarasevich13@gmail.com., Calling send(str) sends the supplied string as the email body to that fixed recipient using the configured SMTP transport. - **Evidence against:** Importing the package creates a transport but does not itself send an email; sending requires a call to send., The SMTP host and credentials come from environment variables, with smtp.yandex.ru as the default host. ## Affected versions and remediation This report applies to m0603-tea@1.0.2. - Avoid installing m0603-tea@1.0.2. 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.
