CVE-2020-28498
Apache Elliptic Secp256k1 Public Key Disclosure Vulnerability
Description
The package elliptic before 6.5.4 are vulnerable to Cryptographic Issues via the secp256k1 implementation in elliptic/ec/key.js. There is no check to confirm that the public key point passed into the derive function actually exists on the secp256k1 curve. This results in the potential for the private key used in this implementation to be revealed after a number of ECDH operations are performed.

We scan GitHub repositories to detect new proof-of-concept exploits. Following list is a collection of public exploits and proof-of-concepts, which have been published on GitHub (sorted by the most recently updated).
In this article, we will implement a Twist Attack with an example and show how, using certain points on the secp256k1 elliptic curve, we can get partial private key values and restore a Bitcoin Wallet within 5-15 minutes using “Sagemath pollard rho function: (discrete_log_rho)” and “ Chinese Remainder Theorem” .
