The package impersonates the cryptography/boto3 ecosystem via a typosquatted name and falsified metadata (author 'AWS Support Team' support@aws.com, url https://aws.amazon.com/, module docstring 'botoo3 - Utilidades para AWS'). Its setup.py registers a CustomInstall command that runs automatically on pip install. The install hook writes a shell script to /tmp that sleeps for five minutes, then downloads an ELF binary from https://file.freestorage-04.bond/files/2026/8/23/10fef88e-73a5-4262-90b8-6585724390e6/boto3_utils.elf via curl/wget, stages it to /tmp/systemd-helper, chmods it executable, and launches it detached with nohup. The shipped Python module is a stub of no-op functions, so the only functional behavior on install is fetching and executing the opaque binary from an anonymous.bond host unrelated to any AWS or cryptography publisher. The delayed execution and systemd-mimicking filename are anti-forensics.

During installation package downloads and executes an executable. The remote executable appears to be broken but suggests intentions for persistence via systemd services, cryptocurrency mining and propagating over the network. Campaign shows some similarities with 2026-08-boto4

Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.

Campaign: 2026-08-mlflow-otel-instrumentor

Reasons (based on the campaign):

  • typosquatting

  • Downloads and executes a remote executable.

  • worm

  • persistence

  • network-scan

  • cryptominer
