As per this article: https://www.bitdefender.com/blog/hotforsecurity/marvin-attack-resurgence-1998-resolved-vulnerability-makes-a-comeback/

The "Marvin Attack" appears to affect major cryptographic protocols on the Internet (TLS, ECDSA, Diffie-Hellman), and while it claims it's not in the wild (yet), as a layman, at the surface this appears extremely concerning, given those protocols are used extensively to secure major parts of the Internet, specifically TLS (secure browsing with https), Diffie-Hellman (VPNs)... including Bitcoin.

ECDSA is used by Bitcoin for Key generation, address generation, and trasaction signing & verification.

At any rate, I am wondering what the Bitcoin OGs think of this new vulnerability and if Bitcoin Core devs are already on this, or whether this is nothing to worry about because .... <insert reasons here>

Thanks in advance.
