  1. The goal of a dusting attack is to break the privacy of Bitcoin and cryptocurrency users by sending tiny amounts of coins to their wallets. The transactional activity of these wallets is then tracked down by the attackers, who perform a combined analysis of different addresses to deanonymize the person or company behind each wallet.

  2. If attackers are successful at linking the dusted addresses and wallets to their respective companies or individuals they may use this knowledge against their targets, either through elaborated phishing attacks or cyber-extortion threats.

  3. Dusting attacks work for both if we move the dust.
    Since dusting attacks rely on a combined analysis of multiple addresses, if a dust fund is not moved, attackers aren’t able to make the connections they need to “deanonymize” the wallets.

  4. The Samourai Wallet team implemented:

  • a real-time alert for dust tracking and
  • a “Do Not Spend” feature that lets users mark suspicious funds, so these are not included in future transactions.

1)A dusting attack refers to a relatively new kind of malicious activity where hackers and scammers try and break the privacy of Bitcoin and cryptocurrency users by sending tiny amounts of coins to their wallets.

  1. The goal is to de-anonymise blockchain users
    (however, neither the article nor the video explain EXACTLY HOW the dust makes it any more able to de-anon a user over just doing normal block-chain analytics!!! like how does it actually give them more info than just regular linking of addresses)
  2. A link to real world identity, i.e. loss of anonymity
  3. Assume Both?
  4. Warning of dust transactions and ability to mark them not to be spent.
