A large scale attack against privacy
The tweet also links to a transaction — which according to Binance is part of the attack — sending a fraction (0.00000546 LTC) of a coin to 50 addresses. Furthermore, the exchange also links to an explanation of a dusting attack, which defines it in the following way:
“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 personal wallets.”
A data acquisition strategy
The way this kind of attack works is that the attacker can then track down the transactional activity of these wallets. By analyzing this data, the attacker tries to determine the identity of who controls those wallets.
