PLATINUM is an advanced persistent threat group also known as Fallow Squall, Gingersnap, Parasite, Rubyvine, and TwoForOne. The group has used spearphishing emails with malicious attachments as a primary initial-access vector, relying on user execution of malicious files. It has employed multiple keylogging tools and exploited Microsoft Office vulnerabilities to gain code execution and subsequently escalate privileges to SYSTEM. PLATINUM has also used Intel Active Management Technology Serial-over-LAN capabilities to transfer files and conceal command-and-control activity from operating-system-level security controls.

Let’s take a look at the vulnerability CVE-2015-2545 and its extension CVE-2015-2546. Microsoft Office versions 2007 SP3, 2010 SP2, 2013 SP1 and 2013 RT SP1 are exposed to the former – it allows remote attackers to execute arbitrary code using a crafted EPS file.
This detection identifies instances where Windows Explorer.exe spawns PowerShell or cmd.exe processes, particularly focusing on executions initiated by LNK files. This behavior is associated with the ZDI-CAN-25373 Windows shortcut zero-day vulnerability, where specially crafted LNK files are used to trigger malicious code execution through cmd.exe or powershell.exe. This technique has been actively exploited by multiple APT groups in targeted attacks through both HTTP and SMB delivery methods.
The latter allows remote attackers to execute arbitrary code in kernel mode. Both vulnerabilities were used in a targeted attack by the Platinum (aka TwoForOne) group. The attackers first exploited CVE-2015-2545 to execute code in the process WINWORD.EXE, and then CVE-2015-2546 to escalate privileges up to the SYSTEM level. CVE-2015-2546 is a classic Use-After-Free (UAF)-type vulnerability.
