Details

Source: kam193 (22f9a9b921e53b4755c41241969fcc8b410b09f29a63ed9c23c5a19c966b4946)

During installation, the package starts obfuscated code that downloads and runs remote executables in specific environments. In some packages in the campaign, the code only attempts to exfiltrate some basic information using DNS requests and then likely cover tracks by installing a similarly named package from private repository

Related campaigns: 2026-02-spark-audit-notify, 2026-03-geekennedy

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

Campaign: 2026-02-urllib-slim

  • Downloads and executes a remote executable.

  • obfuscation

  • dependency-confusion
