I've just tried synchronizing with v1.3.1 daemon and the backup block data at May 25th.

After block 248957, "duplicate inputs" message emerged, so sure enough, there was attacks, I think.

Interestingly, v1.3.1 daemon didn't stop synchronizing after block 248958.
It processed 300+ orphan blocks, and recorded hash values below:
height=248958: 00000022193d53b1aa17ac7b86fce2ceecbaba36f0e6d2a0a483c227d7aa4d67
height=248959: 00000013b54daf77086e740d4e0d7721afd933614c84321c54d2f4d85e553d42
These are same as the values on the Yenten Explorer https://ytn.overemo.com/

So...now, the Yenten blockchain became quite unhealthy...we will get different hash value from different version nodes.
CVE-2018-17144-fixed wallet may be useless in this situation...

And "duplicate inputs" messages still continue emerging on debug.log...it looks hopeless for me, unfortunately.

Edited:

I've deleted my CVE-2018-17144-fixed Windows binaries:
https://github.com/ohashi3d/yenten/releases/tag/2.0.1fix_CVE-2018-17144

Though I may still try running Yenten daemon for my technical interest,
Good bye Yenten, for a while, or eternally...

I have also downloaded the blockchain since May 20 and nothing has stuck with me.

But the problem is that when receiving new blocks, the wallet checks the blockchain and API RPC begins to respond to the request for a long time.

Code:
