Looks interesting. Crop: C-style language ROP Compiler for CFI-hardened system attacks.
A bit interesting point of this sample is that it seems to have two ROP chains: for 32bit and 64bit.

This CVE-2017-11826 sample exploits with RETsled and ROP using msvbvm60.dll. EMET ROPGuard probably stops it. xitter.cf/0x009AD6_810/status/91…

hmm... what happened on Plaid CTF account?
rtfobj may be slightly better judging from my daily use.
I plan to conduct a quantative analysis on rtfobj and rtfdump for their object extraction abilities against malicious RTFs.
