ST. CHARLES, MO (KTVI)– An international conference for computer hackers wrapped up Tuesday in St. Charles.

This conference of so-called ethical hackers is on two parts, Hacker University which allows hackers to update skills and Take-Down-Con a conference on how to stop bad guy hackers from taking down websites and networks.

While we watched, Wayne Burke hacked into giant European bank ING.

“In this case, I’ve already got the email addresses of probably 100 ING employees,” said Wayne Burke of SecurIT Corporation in Netherlands.

So he could e-mail them, and as soon as one email was opened, he would be inside the ING computer system.

“They now have remote access to the core inside network of that organization,” Burke stated.

The hackers could steal money or information or both.

Or they can use one of these.

“This is a customized miniature super-computer,” said Burke.

It costs $90 and can give hackers wireless total access to a computer system. It’s all part of a conference called Take-Down-Con.

“This is cyber, offensive cyber-security experts from all around the world have come in and they’re teaching local IT professionals how attacks actually happen so they can better protect against them,” stated Dave Chronister with Parameter Security in St. Louis.

“Sometimes the word ‘hacker’ comes up and they automatically assume you’re doing something illegal or bad when hacker just means, essentially, someone who enjoys bypassing limitations,” said Adrian Crenshaw with Security in Indiana.

So how safe is your on-line information from people who want to bypass limitations and rip you off?

“A lot of it comes down to ethics, and ethics is a hard thing to teach,” said Crenshaw.

What about the recent Schnucks cyber-attack fiasco? These hackers say at least Schnucks caught it.

“And FBI survey says only 2 percent of all attacks are actually detected. So really with the Schnucks standpoint, for every Schnucks that are out there, there could be 49 other attacks that we don’t even know about,” said Chronister.

And that’s the point these white hat hackers are making to companies, stay aware and keep your security updated.

Their advice to consumers is to minimize personal information posted on Twitter and Facebook and change your passwords every so often.
