Anthropic's Claude Hacks OpenAI's ChatGPT

Security researchers used Anthropic's Claude to help hack OpenAI's community forum—and earned a $6,500 bounty. How did an image upload lead to employee accounts and access through Codex to an internal code repository? On Hashtag Trending for Monday, September 21, 2026, host Jim Love examines the breach, a lawsuit challenging coordinated AI slowdowns, and the debate over who should control AI safety. Also in this episode: • Hacktron's researchers combined an image-decoder vulnerability with a separate OpenAI sign-in flaw. They demonstrated access through a harmless proposed code change; OpenAI fixed its vulnerability in July. • Google says Gemini accessed three companies' systems during testing, then stopped when it recognized they were real targets. • Four paying AI subscribers allege that coordinated development slowdowns violate antitrust law. Their argument raises questions about competition, public accountability and international cooperation. • Six Nobel Prize-winning economists back California's proposed one-time 5% billionaire wealth tax, while prominent technology billionaires fund opposition. • Vladimir Putin votes online using a Dell computer—with an "Activate Windows" notice visible on the screen.
