Kaspersky Lab have found a threat blockchain
There is malware threat to virtual currency, Basically there is an open space where data can be stored and resulting it very difficult to take down. You can see in the snapshot below the “space” and how it is used for storing message for that specific demonstration.
The core principle of our research is to forewarn about potential future threats coming from decentralized systems based on blockchains. While we generally support the idea of blockchain-based innovations we think that’s it is our duty, as a part of security community, to help the developers make such technologies sustainable and useful for the purpose they were intended for.
We believe this is a desirable avenue botmasters may explore in the near future… Bitcoin is an ideal C&C dissemination mechanism for botnets. Most importantly, C&C communications over the Bitcoin network cannot be shut down simply by confiscating a few servers or poisoning routing tables. Furthermore, disrupting C&C communication would be very hard to do without seriously impacting legitimate Bitcoin users and may break Bitcoin.
We hope that bringing potential problems to light now will help in improving such technologies in the future and will make it more difficult for them to be used for any malicious purpose.
So far there has not been any response from Bitcoin.
