The \\n\\nWhat makes this activity notable is that it shares significant targeting overlaps with TeamPCP, a threat actor that rose to prominence late last year by exploiting known security vulnerabilities (e.g., React2Shell) and misconfigurations in cloud services to enlist the endpoints in an ever-expanding network for conducting data theft and other post-exploitation actions.\\n\\nAt the same time, PCPJack lacks a cryptocurrency mining component, unlike TeamPCP. While it’s not known why this obvious monetization strategy was not adopted, the similarities between the two clusters indicate that PCPJack could be the work of a former member of TeamPCP who is familiar with the group’s tradecraft.\\n\\nThe starting point of the attack is a bootstrap shell script that’s used to prepare the environment \u2013 such as configuring the payload host \u2013 and download next-stage tooling, while simultaneously taking steps to infect its own infrastructure, terminate and remove processes or artifacts that are associated with TeamPCP, install Python, establish persistence, download six Python scripts, launch the orchestration script, and remove itself.\\n\\n\\n\\nThe six Python payloads are as follows -\\n\\n * **worm.py** (written to disk as monitor.py), the main orchestrator that launches the purpose-built modules, conducts local credential theft, propagates the toolset to other hosts by exploiting known flaws (CVE-2025-55182, CVE-2025-29927, CVE-2026-1357, CVE-2025-9501, and CVE-2025-48703), and uses Telegram for command-and-control (C2)\\n * **parser.py** (utils.py), to handle credential extraction to categorize stolen keys and secrets\\n * **lateral.py** (_lat.py), to facilitate reconnaissance, harvest secrets, and enable lateral movement across SSH, Kubernetes, Docker, Redis, RayML, and MongoDB services\\n * **crypto_util.py** (_cu.py), to encrypt credentials before exfiltration to the attacker’s Telegram channel\\n * **cloud_ranges.py** (_cr.py), to collect IP address ranges assigned to Amazon Web Services (AWS), Google Cloud, Microsoft Azure, Cloudflare, Cloudfront, and Fastly, and refresh the data every 24 hours\\n * **cloud_scan.py** (_csc.py), to run cloud port scanning for external propagation via Docker, Kubernetes, MongoDB, RayML, or Redis services\\n\\n\\n\\nPropagation targets for the orchestrator script come from parquet files that the worm pulls directly from Common Crawl, a non-profit that crawls the web and provides its archives and datasets to the public at no extra cost.\\n\\n\\”When exfiltrating system information and credentials, the PCPJack operator even collects success metrics on whether TeamPCP has been evicted from targeted environments in a ‘PCP replaced’ field sent to the C2,\\” Delamotte said. This \\”implies a direct focus on the threat actor’s activities rather than pure cloud attack opportunism.\\”\\n\\nFurther analysis of the threat actor’s infrastructure has uncovered another shell script (\\”check.sh\\”) that detects the CPU architecture and fetches the appropriate Sliver binary. It also scans Instance Metadata Service (IMDS) endpoints, Kubernetes service accounts, and Docker instances for credentials associated with Anthropic, Digital Ocean, Discord, Google API, Grafana Cloud, HashiCorp Vault, OnePassword, and OpenAI, and transmits them to an external server.\\n\\n\\”Overall, the two toolsets are well developed and indicate that the owner values making code as a modular framework, despite some redundancies in behavior,\\” SentinelOne said. \\”This campaign does not [deploy miners], and it deliberately removes the miner functions associated with TeamPCP. Despite that, this actor has well-defined scopes for extracting cryptocurrency credentials.\\”\\n\\nFound this article interesting?
