The paper by @nadiaheninger and me, where we search (and find) ECDSA signatures in Bitcoin, Ethereum, Ripple, SSH & HTTPS with nonces that are not properly randomized, to be presented at Financial Crypto, is online now:

Ok look. My cryptanalysis game sucks.
I’ve been working on the 10(ten!) pt yodawg encraption challenge from @open_ctf 2018 since I got home.
I freely admit my weakness and need some teaching.
Anyone out there solve that damn thing who can give me a hint or coaching? Thanks

A huge thanks to @travisgoodspeed for fulfilling a last minute request on Sunday to come by the DEFCON contest area to autograph the copies of "PoC||GTFO Volume II" that were given out to the winners of @open_ctf. Further thanks go to @nostarch for graciously donating them.

Once again, V& knocked it out of the park with this year's @open_ctf. Definitely need to bring more people next year though.
