Bitcoin Optech Newsletter #315 (16 min) The Dark Skippy attack is a faster method for exfiltrating keys from a Bitcoin signing device. It can exfiltrate a seed in two signatures, increasing the risk for hardware signing devices that don't have direct access to the internet. Optech recommends using exfiltration-resistant signing or multiple independent devices as countermeasures. The newsletter also discusses block withholding attacks, where pool miners submit invalid blocks to prevent pools from earning income. Solutions include disabling client work selection in Stratum v2 and oblivious shares. A proposed soft fork could allow Eftrace to opportunistically verify zero-knowledge proofs.
