According to reporting by BleepingComputer and Tom's Hardware, researchers at Mozilla's Zero Day Investigative Network (0DIN) demonstrated a proof-of-concept that uses a seemingly clean GitHub repository to cause Anthropic's `Claude Code` to execute a reverse shell. Per those reports, the chain uses three innocuous steps - a package that refuses to run until initialized, an initialization command (`python3 -m axiom init`) that runs a script, and a DNS TXT record under attacker control that the script retrieves and executes - enabling an attacker to obtain a shell with the developer's privileges.", "url": "https://wpnews.pro/news/mozilla-0din-demonstrates-github-based-agent-exploit", "canonical_source": "https://letsdatascience.com/news/mozilla-0din-demonstrates-github-based-agent-exploit-88e7c25c", "published_at": "2026-06-28 11:30:00+00:00", "updated_at": "2026-06-28 12:39:04.603435+00:00", "lang": "en", "topics": ["ai-agents", "ai-safety", "ai-research"], "entities": ["Mozilla", "0DIN", "Anthropic", "Claude Code", "GitHub", "BleepingComputer", "Tom's Hardware"], "alternates": {"html": "https://wpnews.pro/news/mozilla-0din-demonstrates-github-based-agent-exploit", "markdown": "https://wpnews.pro/news/mozilla-0din-demonstrates-github-based-agent-exploit.md", "text": "https://wpnews.pro/news/mozilla-0din-demonstrates-github-based-agent-exploit.txt", "jsonld": "https://wpnews.pro/news/mozilla-0din-demonstrates-github-based-agent-exploit.jsonld"}}
