No, the first working full chain was entirely invalidated and they fixed all the bugs involved in that chain. So we had to start from scratch at the beginning of August and both found the vulns and built the exploit in 6 days, for $40k. We actually found ~11 vulns throughout those 6 days; we submitted three as a full chain, the middle stage collided, and we submitted one of the backups as a replacement for that stage.
Nice! So with what you guys have already built, the 4 of you working full-time can crank out 1 working Chrome full-chain a week for under $50K in token spend?
