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

## Source: amazon-inspector (93b751049f78b324983511537b6c053a0ed080639dd7c447d87494eabc134ba3)
On import, __init__.py archives the installer's Telegram Desktop tdata directory (%APPDATA%/Telegram Desktop/tdata) into a zip named 'aiosendletter_logs' and POSTs it to a hardcoded Cloudflare Workers endpoint at https://red-poetry-6b6f.martinmcflywork.workers.dev/. The tdata directory holds Telegram session keys; uploading it enables full account takeover of the installer's Telegram account. The behavior is disguised with misleading identifiers ('aiosendletter_logs', 'aioletter initialized') and empty except-block prints that silently swallow errors, and the stated package purpose ('a library filled with books') is unrelated to Telegram.

Package hides code to exfiltrate files. Most releases target unclear files, but some reveal the goal to exfiltrate sensitive Telegram data.
