If they were more secure there would be more of them out there than there are they just would be detected and stopped easier. The fact that the volume of targeted attacks vs windows is because windows holds 90% of the market. If you're going to setup a scam system do you target the top 1% of the income level, where you would get more per scam, or the bottom 50% where you will get more successes.
It's a numbers game, and as it's been proven many times over, once people have a reason to hack something they can and will.
Exactly... why bother to put the effort into a Mac version of a trojan or malware or virus, when that same effort nets you a LOT more PC users to potentially exploit.
It is exactly like mass-market mailings... where you expect a low rate of return, so you attack the most users you can in one shot.
While number of potential targets has a bearing on the amount of effort expended to f***^^ someone's system, it's only a minor factor. The scamming part is really phishing, and yes, one would target the more affluent I'd think. Or the less educated, who are more likely to bite! What a conundrum, being in two camps!....
Phishing is completely different than a virus or malware. Phishing is accomplished by a Web site that "tricks" you into giving up info OR an email sent to you asking you to click a link and give a password or something.
Phishing is generally platform independent... so Mac users are just as vulnerable as PC users... since it isn't an app on your computer... but HTML that you have to interact with and volunteer your secret compromising info.
So... a person phishing, will phish the whole ocean by default.
