More Targeted PDF 0-Day
Summary: Cisco Talos reported an unpatched Adobe/PDF vulnerability that works across multiple operating systems, bypasses Adobe's sandbox, and has been used in recent targeted campaigns. The sample opened with a roughly 400K+ block of highly obfuscated JavaScript, far larger than the small, well-defined scripts typically found in PDFs.
Key Takeaway: The flaw has no patch yet and already bypasses Adobe's sandbox in live targeted campaigns, so the usual assumption that sandboxing contains a malicious PDF does not hold here.
