To summarize the article, it basically talks about a hacker who used his Twitter account to send out messages that were in turn used to direct the infected PCs to malicious websites. Ethical Question: I think it is actually quite important to look at the intention behind using technology in this way. In this case, the hacker took advantage of his Twitter account to engage in criminal activities. But what if this for of hacking was used to perhaps take down an online criminal ring? Would it still be considered 'right' or 'ethical' to hack into other people's computers in that case? Ethical Problem: I think the main problem would be accountability. To what extent should Twitter be held responsible?
