The destination bot token and wallet paths are stored as base64 blobs (constants TK, XMR_WIN, XMR_LINUX) and decoded at runtime to conceal the exfiltration target. The exfil routine is invoked at module top level, so any `import btcflip` (which loads the inner `kotoraka` module) triggers wallet theft. The code also terminates feather/monero processes to release file locks before archiving. The stated purpose of the package is unrelated to Monero wallets and is a cover story for wallet theft.\n\n## Source: kam193 (2b305ae4851e877fcea4950e019342d31782bde7e3c49d11847e2ede65776f78)\nDuring import, the package exfiltrates cryptocurrency wallet files.\n\n\n---\n\nCategory: MALICIOUS - The campaign has clearly malicious intent, like infostealers.\n\n\nCampaign: 2026-08-kotanku\n\n\nReasons (based on the campaign):\n\n\n - exfiltration-crypto\n\n\n - uses-telegram-bot\n",
