Summary
Crypto wallets implementing the GG18 or GG20 TSS protocol might allow an attacker to extract a full ECDSA private key by injecting a malicious pallier key and cheating in the range proof. Depending on the Beta parameters chosen in the protocol implementation, the attack might require 16 signatures or more fully exfiltrate the other parties' private key shares.
Risk Assessment
Organizations using these wallets may be exposed to private key theft, leading to loss of funds and data security breaches. Attackers could gain access to sensitive information and resources.
Recommendation
It is recommended to update crypto wallets to the latest versions that mitigate this vulnerability. A security audit of the TSS protocol implementation should also be conducted.
