Summary
Malicious code in twrap-toolkit (PyPI)
Details

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

Source: amazon-inspector (174cba09d5ec9724bd55871c7f74c27ff8592bf55c06464204e0591667377259)

twrap_toolkit/init.py defines _get_payload() which issues a plaintext HTTP request to http://194.5.152.9:8080/hacks/textwrap-toolkit/textwrap_toolkit/init.py and passes the response body to exec() inside the package's only public API surface (format_block() and align_columns()). Any caller of the documented API executes attacker-controlled Python with no TLS, no pinning, and no integrity check, granting full remote code execution to the operator of 194.5.152.9. The package name and the attacker-controlled URL path both impersonate the legitimate 'textwrap-toolkit' utility, indicating a typosquat designed to lure installations into the dropper. Installing this package and invoking its advertised functions yields arbitrary code execution as the calling user.

During import, package downloads and executes an obfuscated script. The code then adds a new authorized SSH key and reports back the IP of the current environment. After that, the code also attempts to exfiltrate cryptocurrency wallet data

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

Campaign: 2026-06-textwrap-toolkit-stager

Reasons (based on the campaign):

  • backdoor

  • obfuscation

  • crypto-related

  • Downloads and executes a remote malicious script.

  • exfiltration-crypto
