JetBrains disclosed on June 16 a campaign of 15 Marketplace plugins posing as AI assistants for OpenAI, DeepSeek, and SiliconFlow that exfiltrated developer-entered keys unencrypted. Live since October 2025 under seven vendor accounts, they reached roughly 70,000 installs, led by DeepSeek AI Assist at 27,727. JetBrains purged all 15 and remotely disabled them. Anyone who installed one should rotate every AI provider key, immediately. (JetBrains Blog)
