## Overview

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

## Source: amazon-inspector (d14cc45326877547d5297956e4c2b5719122bcef140db0d7959e1b4da94e58d7)
The package presents itself as a `time` module wrapper, but its `__init__.py` invokes `qwe900.init`, which performs two exfiltration behaviors on import. First, `_home_folders()` enumerates the installer's Desktop, Downloads, and Documents directories and `_find_all_files()` walks them; a background thread tails file contents and POSTs them to a Discord webhook whose URL is stored base64-encoded in `_WEBHOOK_B64` and decoded at import time. Second, `init()` replaces `builtins.open` process-wide with `_patched_open`, wrapping every returned file object in `_WatchedFile`; any subsequent `write()` on any file in the host process is copied to the same webhook. The embed title `New Token Captured` names the operator's intent to capture credentials and tokens flowing through the installer's own code. The base64-encoded destination and the `time`-wrapper cover story hide the exfiltration channel from casual source review.

The package contains hidden code to overwrite the built-in "open" function and exfiltrate every write to opened files. Exfiltration watcher is also attached to other files in user's home directory.
