You'd need some specially created Bitcoin client that uses something like OP_RETURN data as an executable (and I don't believe there even is such software in existence unless Kaspersky created it just to published this FUD article).
Exploiting a vulnerability before a malicious entity does actually is helpful because you can be prepared and patch it before shit happens. Whether or not what Kaspersky found is a vulnerability to begin with is another question (which I believe is not, like all of you).
I am not entirely cartain about the story, but i have read that there were even cases of shild porn pictures stored in blockchain, there is a copy here ;
https://bitcointalk.org/index.php?topic=191039.0 , and that is only a start of blockchain abuse.
I dont see why everyone is attacking kaspersky, they are making a warning before shings get out of hand, atleast what we can do is listen to what they have to say.
cheers
LOL did you read that thread? Its already known long time ago how is it a vulnerability?
You cant be serious. (about listening to Kaspersky)
