VB2019 paper: Attribution is in the object: using RTF object dimensions to track APT phishing weaponizers

Posted by    on   Mar 12, 2020

Malicious RTF files, exploiting vulnerabilities in Microsoft Office, have long been a popular way to deliver malware, most often through (spear-)phishing attacks. Such files are often created using exploit builders, which were the subject of a VB2018 presentation by Sophos researcher Gábor Szappanos.

One such builder (or weaponizer) is ‘Royal Road’, which has been used by various Chinese APT groups to deliver malware. Royal Road and how the properties of RTF files can be used to track weaponizers and their users were the subject of a VB2019 paper by Michael Raggi (Proofpoint) and Ghareeb Saad (Anomali).

Today, we publish the researchers' paper in both HTML and PDF format as well as the recording of their VB2019 presentation.
