Exploit discovered in Bitcoin core
 

DDOS vulnerability

Over the last 24 hours, the cryptocurrency community has been discussing a critical vulnerability that was found in the Bitcoin Core (BTC) reference client. A bug introduced in Bitcoin Core version 0.14, that also affects all subsequent versions, could have caused a great majority of current Core nodes to crash. According to the developer’s Optech newsletter, Core contributors released a patch that fixes Core version 0.16.2 and the latest 0.16.3 fix requires an immediate upgrade.

Looks like it did not have much of an impact on BTC price

I bet people all around the world are hacking all day long trying to bite a piece of that apple

It requires the attacker to generate a block, so it would cost $80k+ in lost revenue, not to mention the potential drop in price. So it's not impossible by any means, but it wouldn't just be some asshole doing it for the lulz.
