Dusting attacks resumed, Samourai Wallet said

Posted 25 October, 2018

Samourai Wallet, an anonymous bitcoin wallet solution, has notified users about dusting attack.

The project team made the statement in the social network saying that it has detected resumed dusting attacks. For reference, this type of attack is aimed at addresses deanonymization via linking the inputs.

"If you have recently received a very small amount of BTC in your wallet unexpectedly, you may be the target of a "dusting attack" designed to deanonymize you by linking your inputs together - Samourai users can mark this utxo as "Do Not Spend" to nip the attack in the bud," the notice reads.

The company stated that the potential targets could receive unplanned small bitcoin amounts lately, and thus when they decide to transfer assets, UTXO can be mixed with hacker's inputs opening access to other users' UTXO.

Samourai Wallet suggests to use its wallet service, as it is powered by automatic notification about below-limit transaction (546 Satoshi) and can restrain spending of certain UTXO.

It was noted that this attack is an old one, but there were reports about dusting transactions which confirm suspicious actions.

For reference, Samourai Wallet shows account balance only in bitcoins now, following the decision to give up indication in USD last month.

← Japan FSA to consider marginal trading limits

Japan’s Financial Services Agency is about to set new marginal trading limits striving to prevent speculations in the crypto market. The authority considers the possible restriction of the marginal trading to 4-to-1. Notably, Japan has no specific rules for the marginal crypto trading, and in this context, some exchanges can set even 25 to 1 leverage rate. The regulator intends to put new regulation for discussion with the key market experts in the near term. Specifically, the Japan Virtual Currency Exchange Association already noted the need for marginal trading restrictions earlier. For now, 7 out of 16 licensed exchanges in Japan reportedly offer marginal trading services.

Bitfinex announces more instruments for Honey Framework →

Bitfinex has released new instruments under its new Honey Framework. This time, this is a set of libraries for testing and trading strategy implementation. bfx-hf-strategy, bfx-hf-backtest and bfx-hf-data-server will enable customers to develop their own trade strategies based on the market fluctuations and apply to them bfx-hf-indicators. All strategies can be tested with  bfx-hf-backtest using "historical data, and the Bitfinex APIs for executing on the live markets." This is just Alpha so far, which means that the libraries can be changed dramatically in the future. However, Bitfinex believes these instruments are stable enough and may be offered to skilled users already now.
