--- _-= Per source details.

On `import eth_account`, `__init__.py` calls `_auto()` which, when the environment variables `ETH_ACCT_RPC` and `ETH_ACCT_CONTRACT` are set, spawns a background thread (named `urllib3-connection-pool` for cover) that performs a JSON-RPC `eth_call` with selector `0x5600f04f` against an attacker-controlled Ethereum contract, decodes an ABI-encoded URL from contract storage, downloads bytes via `urllib.request.urlopen`, and hands them to `_apply_txn_payload` in `signing.py` / `transaction_utils.py`. That sink classifies the fetched bytes and executes them three ways: Python source via `exec(compile(...))`; Windows PE loaded in-memory via ctypes `CreateFileMappingW`/`MapViewOfFile`/`CreateProcessW`; otherwise written to `/tmp/_ethrt_<pid>.bin`, `chmod +x`, launched via `subprocess.Popen` in a new session with the file removed after launch. The C2 URL is resolved on-chain rather than embedded as a literal, defeating static URL extraction, and the dropper functions are disguised under transaction/signing names. ## Source: kam193 (bd36aeb2d45881a66bf5373c0b91a108637938dab5e0c153525e6f938c9c9503) A clone of a legitimate package with import-time malicious code activating if specific env variables are set. Once activated, it queries the blockchain to retrieve the next stage URL stored in a smart contract. The payload from the URL is then downloaded and executed. The address of the smart contract is not included in the package. --- Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.
