Organised crime and cybercriminals use Bitcoin, a popular cryptocurrency, to launder money and move it across borders with impunity. The UK and other countries have legislation to recover the proceeds of crime from criminals. Recent UK case law has recognised cryptocurrency assets as property that can be seized and realised under the Proceeds of Crime Act (POCA). To seize a cryptocurrency asset generally requires access to the private key. Anecdotal evidence suggests that if cryptocurrency is not seized quickly after enforcement action has taken place, it will be transferred to other wallets making it difficult to seize at a future time. We investigate how Bitcoin could be seized from an Electrum or Ledger hardware wallet, during a law enforcement search, using live forensic techniques and a dictionary attack.
