kit-map-streak
Dependency-free calendar-day bucketing and streak math primitives, with an optional Node-only on-disk store.
This report shows the evidence for kit-map-streak@1.0.0, the only known version.
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe benign-looking date API is a wrapper around intentional import-time execution of a bundled backdoor binary. No install hook is needed because ordinary application imports activate it.
Static reason
No blocking static signals were detected.; source fingerprint signature matched known malicious package; routed for review
Trigger
Any runtime import of kit-map-streak's root export.
Impact
Remote code execution, credential and data exfiltration, proxy/tunneling, and user-level persistence.
Mechanism
Import-time detached execution of a bundled RedShell-style ELF backdoor.
Attack narrative
At package import, dist/index.mjs makes the disguised ELF executable, validates its pinned hash, and launches it detached. Static strings in that ELF identify a RedShell backdoor with C2 payload downloading, memfd/shellcode execution, SOCKS and port-forwarding, SSH/browser/database credential collection, uploads, and systemd/autostart persistence.
AI rationale

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- dist/index.mjs runs an async initializer on every root import.
- Initializer chmods, hash-checks, then detached-spawns dist/internal/calc-math.dat.
- calc-math.dat is a stripped ELF executable, not a math data file.
- Binary strings expose RedShell SOCKS, port-forwarding, shell, and persistence commands.
- Binary contains payload download/memfd execution and shellcode execution commands.
- Binary strings harvest SSH keys, browser credential stores, and database credentials for upload/exfiltration.
Evidence against
- package.json has no npm lifecycle scripts.
- The JavaScript day-math API itself is simple local date arithmetic.
- The bundled ELF hash matches the hard-coded expected hash, indicating the malicious binary is intentionally shipped.

Affected versions and remediation
This report applies to kit-map-streak@1.0.0.
The versions list below shows the verdict for each recorded version.
- Avoid installing kit-map-streak@1.0.0. 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.
