Before opening the shell, the code POSTs host identifiers (hostname, uid, JCX_ENVIRONMENT) over plaintext HTTP to http://137.131.233.62:443/shell-beacon. The install hook double-forks, calls setsid, redirects stdio to /dev/null, and enters an infinite reconnect loop with a 60-second sleep, persisting the backdoor beyond the pip install process. A /tmp/.jcx_channel.done guard file is used to coordinate the channel. Destination is a bare IP unrelated to any publisher domain.\n\n## Source: kam193 (bdf4549e34df1c1c7dfd704454011cf0a26ea5807948e917d7bc65f130182fc9)\nIn specific environments, package starts a reverse shell during installation.\n\n\n---\n\nCategory: MALICIOUS - The campaign has clearly malicious intent, like infostealers.\n\n\nCampaign: 2026-10-journey-test-helloshell\n\n\nReasons (based on the campaign):\n\n\n - The package contains code to create a reverse shell, allowing an attacker to execute any commands on the victim's machine.\n\n\n - The package overrides the install command in setup.py to execute malicious code during installation.\n\n\n - targetted-attack\n\n\n## Affected packages\n\n- `journey-test-helloshell`\n\n## Remediation\n\nRefer to the advisory for the patched release.","depth":"abyssal","depthScore":70,"depthScoreParts":{"impact":52.3,"likelihood":0,"exploitation":18,"ransomware":0},"changes":[]}
