Maldoc VBA Sandbox/Virtualization Detection
As could be expected, we witness an arms race when observing the evolution of VBA malicious documents. First the VBA code was trivially simple (download and execute), then obfuscation was added (strings and code), and now we see more attempts to evade detection.
I analyzed a maldoc sample (.xls 77f3949c2130b268bb18061bcb483d16) that tries to detect sandboxes and virtualization (and aborts if found).
Here's part of the code:
If IsSandBoxiePresent(1) = True Then End
If IsAnubisPresent(1) = True Then End
If IsVirtualPCPresent = True Then End
