As stated currently, the attacks are all DoS (but perhaps they downplay the severity before the full nature of attacks will be disclosed to the public?)
The three vulnerabilities have been rated as medium
severity with low difficulty to exploit and expose the
Bitcoin node software to Denial of Service attacks
resulting in a high overall risk rating.
- empath75 8y agoWould a DOS attack enable someone to do a double spend by taking honest nodes offline?
- imglorp 8y agoYeah I think that's the problem: an attacker can gain a majority of dishonest nodes.
- nullc 8y agoThat isn't the case here. (also, in Bitcoin "majority of nodes" doesn't do much to aid attacks)
- eridius 8y agoWhy not? If you have a sizeable percentage of the mining power, and you can DDoS enough other miners to leave you with 51% of the mining power, doesn't that allow you to double-spend? Edit: After reading other comments, I take it the answer to "why not?" is "because this isn't actually a DDoS".
- nullc 8y agoAlso because if it were, what you'd have to DDOS is hashpower not nodes-- and lots (hopefully most) hashpower is not directly inbound reachable: it connects outward, and only gets inbound connections via backup nodes at other locations. This makes it harder to DOS attack since you don't know where it is.
