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.\n\n## Source: kam193 (5a4369fbf36c4c2a54c7555febeaf8fda122d33a7ba9b9d11e77031849f5c7d8)\nPackage hides code to exfiltrate files.
