Hackers exploiting Acrobat Reader zero-day flaw since December
Attackers have been exploiting a zero-day in Adobe Reader via specially crafted PDFs since at least December, using a sophisticated fingerprinting-style exploit that runs on the latest Reader without user interaction. The exploit harvests local data using Acrobat APIs and can deploy follow-on RCE/SBX stages, so researchers advise not opening PDFs from untrusted sources until Adobe issues a patch. #AdobeReader #HaifeiLi
