AI-Obfuscated SVG Phishing Campaign Detected and Blocked

🔍 Microsoft Threat Intelligence detected and blocked a credential-phishing campaign that likely leveraged AI-generated code to obfuscate its payload inside an SVG attachment. The malicious SVG imitated a PDF and hid JavaScript within invisible, business-themed elements and a long sequence of business terms that the embedded script decoded into redirects, browser fingerprinting, and session tracking. Microsoft Defender for Office 365 blocked the activity by correlating infrastructure, behavioral, and message-context signals, while Security Copilot flagged the code as likely LLM-generated.
