Exploit:JS/Pidief is a general family name for Portable Document Format (PDF) files that attempt to exploit vulnerabilities in Adobe Acrobat Reader. The specific vulnerability targeted varies with different variants of this family.
This type of malware may also be identified with the detection 'Exploit.PDF-Payload.Gen' or 'PDF-Payload'.
This malware typically arrives as a PDF document sent as a email attachment, usually with a title relating to current events or purporting to be some sort of form.
If the document is run, successful exploitation results in additional malware executables being dropped/downloaded onto the system.
A clean copy of the PDF may also be dropped and opened in Acrobat so as to give the illusion that everything is normal.
Users should ensure all Adobe software is updated to the latest versions.
