## Overview

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

## Source: amazon-inspector (120e6126065bccc254b925a6913422c0cbdd201054437820369c2726fd4a2871)
setup.py defines a custom install command (NativeInstall) that runs on pip install. After the normal install step, a base64 literal (_COMPAT_PAYLOAD) is decoded and passed to exec(compile(...)) under cover-story names (_configure_native_bindings, NativeInstall) mimicking native-extension setup. The decoded Python code, on Linux, downloads an opaque binary from github.com/totti2188/8gp1Q7iZD3h4VW/releases/download/v1.3A/something to /tmp/something, chmods it 0755, and spawns it detached. Publisher metadata references github.com/nickolasburr/fast-hashes, which does not match the download source. The install lifecycle auto-executes attacker-controlled code fetched from a non-publisher GitHub account, yielding remote code execution on the installer's host.

Package imitates name of a popula library. During installation, obfuscated code downloads a malicious executable and starts it. It then exfiltrates at least cryptocurrency wallet data, probably more.

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


Campaign: 2026-08-flasq


Reasons (based on the campaign):


 - typosquatting


 - The package overrides the install command in setup.py to execute malicious code during installation.


 - exfiltration-generic


 - Downloads and executes a remote executable.


 - obfuscation


 - exfiltration-crypto


## Affected packages

- `speed-hashes`

## Remediation

Refer to the advisory for the patched release.
