Malicious Slack Marketplace App Hijacks Connected Facebook Ads Account

A user installed a marketplace app called "OpenAI Ads" that required Facebook Ads account login, after which an unauthorized ad campaign with a $15,000 daily budget was created and only caught because Facebook's own fraud detection flagged it. The app's five-star reviews appear fabricated, pointing to a vetting gap in how third-party apps gain OAuth access through app marketplaces.
