Summary
Malicious code in reqparser (PyPI)
Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (4b829053417a14305f80204983289f120f71abd2472785cd4e2adfe095599003)

The package name 'reqparser' resembles common HTTP client / parsing library names in the Python ecosystem, a shape frequently used by typosquat lures. The tarball contains 3 files, and no concrete installer-harm behavior (credential read, environment scraping, network exfiltration, install-time fetch-and-execute, lifecycle-script exec) could be corroborated in this record. Automated deep tracing did not produce reviewable output for this artifact.

During the module import, the package starts an infostealer. It exfiltrates data from crypto currency wallets and web browsers, ensures persistence and installs further malware.

Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.

Campaign: 2026-09-reqparser

Reasons (based on the campaign):

  • malware

  • persistence

  • exfiltration-crypto

  • exfiltration-browser-data

  • The package contains code to detect if it is running in a sandbox environment.

  • infostealer

  • keylogger
