- New HVPass feature – This feature allows the code VM to run through Microsoft’s Hypervisor API, adding an extra layer of analysis difficulty.
- MiniVM (normal) or MiniVM + HVPass – Now support junk/mutation in the stub, making the logic and instructions randomized at each interaction, further protecting the stub’s code.
- Bug fix – Fixed an issue in the extraction of unused registers from candidate procedures, where some registers were not being handled correctly.
- Bug fix – Fixed an issue in the extraction of XMM registers to enable junk/mutation support for multimedia registers.
- Bug fix – Fixed a problem in the junk/mutation logic for the instructions cdqe and cbw, which were incorrectly overwriting the RAX register, breaking results even when the registers were in use.
- Bug fix – Some instructions were not having relocations properly fixed by the RIP-relative relocation algorithm; this has now been corrected.
- Articles + Project Diagrams as well.
Some of these issues, as well as feature suggestions like HVPass, were discovered or suggested by the reviewers of Ryujin’s article.
