Samourai Wallet Says Bitcoin Privacy Could Be Jeopardized Due To Dusting Tactics
Bitcoin tends to lack in privacy and anonymity, even though there are those that certainly will claim otherwise. The network is meant to be transparent, even though users do not provide any real user information.
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 deanonymise you by linking your inputs together – Samourai users can mark this utxo as "Do Not Spend" to nip the attack in the bud. pic.twitter.com/23MLFj4eXQ

One of the main reasons why privacy-oriented services are popular now is because they “unlink” bitcoin inputs during transactions. Accordingly, it becomes more difficult to link transactions together and to effectively remove the trail of digital elements bitcoin transfers leave behind. Though it is not an illegal business model, some people will use the service for nefarious purposes.
It is also important to keep in mind that such privacy-oriented solutions are not perfect. The cryptocurrency space can be easily disrupted with enough effort and money and it also appears that one particular method of attack is being looked at by a particular entity. The attack, called “dusting” revolves around selling fractional amounts of bitcoin to different users.
One of the most significant issues associated with such attacks is that it can link wallet address inputs together. Users claiming the funds as their own will not be at risk of having their privacy disrupted, so long as they receive funds that are not spent in the process. Various wallet services made the process a bit easier, although most Bitcoin users may not be bothered by the development.
The attack is also noteworthy because it confirms bitcoin’s transparency, as attackers can find addresses of users who may be masking their identity and activity. Further, it also indicates that bitcoin is becoming more popular, which will lead to more attacks in the future.
Regardless of whether anyone actually wants to disrupt bitcoin as a whole is unclear. It is also possible that the attack is not widespread as some say. Further, any incident should be taken seriously though. Bitcoin’s transparency allows developments to take place without much effort.
