I really think a lot of this nonsense can be stopped by people being more careful about their computer security in general. Things like keeping anti-virus software updated and current as well as performing regular spyware and adware scans.
I used to do computer repair as a way to make a little extra money. Almost 100% of the machines I repaired had no antivirus software on them, outdated definitions, or expired antivirus software. Blaming the ecig market is ridiculous, in my opinion. It's the other garbage you download on your machine that will get ya'!
Yes, by all means pay attention to the website's security features. But every vendor I deal with has enough security in place to make me comfortable.
I've also noticed that people will get on public machines and order things online. Then they walk away and leave their info right there for the next person to see as they do not log out of the system before walking away from it.
While I agree many don't take computer security serious some like me do and yet I have had my card hacked twice since I started vaping.
I run norton internet security along with weekly malwarebytes scans. I also use Trusteer Rapport on any site I use a cc. I am behind both a software and hardware firewall. I don't download anything from suspicious sites let alone visit them. So if anyone wants to get my info they would have to work really hard to get it. My bet is anyone smart enough to break through my security isn't wasting their time on my computer but applying their time more efficiently on banks of cc numbers on servers......
