"When a victim simply opens this PDF, hidden code inside it can read files that Acrobat Reader should not be allowed to access and send them to an attacker’s server. Some tests show that it allows attackers to pull in additional malicious code from a remote server and run it on the victim’s machine, potentially escaping Adobe’s sandbox protections."
