In March 2015, Microsoft patched a remote code execution (RCE) vulnerability (CVE-2015-0097) in Microsoft Office. In July 2015, Eduardo Prado released a Proof of Concept (PoC) exploit for this vulnerability here. It did not take long for attackers to repackage this PoC and use it in attacks in the wild. We observed a few variants of attacks exploiting CVE-2015-0097 that are using the same PoC to create a .doc exploit. This vulnerability could also be exploited using other Office file formats.
