Researchers recently have come across fresh samples of malware exploiting the Adobe Reader vulnerability. The new attacks are using a previously unknown command-and-control server and are leveraging the Reader vulnerability to download a binary that will in turn inject a malicious DLL into several running processes if they re found on the compromised machine. Previously identified attacks have been using a PDF that purports to be an employee survey for workers at ManTech, a large defense contractor in the U.S. And in its advisory on the vulnerability, Adobe credited Lockheed Martin for reporting the flaw in the first place.
