It's more than unsettling to realize there are large companies out there developing backdoors, exploits and trojans.

Online crime is practically always international, because they almost always cross traditional national borders.

In the 1980s, in the communist Eastern Germany, if you owned a typewriter, you had to register it with the government. You had to register a sample sheet of text out of the typewriter. And this was done so the government could track where text was coming from.

We're risking the future of the net. People are already losing their trust. Once you get burned once - somebody steals your credit card, or makes a purchase on your account - people tend to stay away from online commerce and from trusting online services.

Nuclear scientists lost their innocence when we used the atom bomb for the very first time. So we could argue computer scientists lost their innocence in 2009 when we started using malware as an offensive attack weapon.

You can get the best locksmith in the world to design the best lock he can design, is it pick proof? No, it's not: it can be very hard to pick, but it is pickable. Because you can get, say, the next 10 best locksmiths, and give them unlimited money and time, they will figure out a way to pick it.

I see beauty in the future of the Internet, but I'm worried that we might not see that. I'm worried that we are running into problems because of online crime. Online crime is the one thing that might take these things away from us.

The vast majority of the online crime cases, we don't even know which continent the attacks are coming from. And even if we are able to find online criminals, quite often there is no outcome. The local police don't act, or if they do, there's not enough evidence, or for some reason we can't take them down.

There is a difference between the stuff that people put online themselves, like pictures and their trips and flights and meals they've eaten, than the stuff that they don't realize is also going into foreign computers. Like, for example, copies of your emails or every single online search you ever do, 'cause all that is being recorded as well.

Governmental surveillance is not about the government collecting the information you're sharing publicly and willingly; it's about collecting the information you don't think you're sharing at all, such as the online searches you do on search engines... or private emails or text messages... or the location of your mobile phone at any time.

Foreigners like me have no privacy rights whatsoever. Yet we keep using U.S.-based services all the time, making us a legal target for gathering and storing our private information. Other countries do surveillance as well. But nobody has the global visibility that United States does.

Antivirus systems need to strike a balance between detecting all possible attacks without causing any false alarms. And while we try to improve on this all the time, there will never be a solution that is 100 percent perfect.
