Ivan Bütler, founder of Compass Security.
We specialise in finding vulnerabilities in cyperspace.
Ethical hackers are good hackers.
They are tasked with finding vulnerabilities
and explaining how to fix them.
Malicious hackers, on the other hand, exploit vulnerabilities.
There are two different ways: either you hack the computer directly,
for example webcams, solar panels, nuclear power plants.
Or you work through humans and send people a Trojan horse
or a phishing page to click on.
The greatest danger is ransomware.
This encrypts the computer and the user is blackmailed
into having the data decrypted.
Updates are important because software is never perfect
and always contains vulnerabilities.
Over time, security vulnerabilities arise
that can be exploited by attacks.
Only up-to-date systems are secure; just like a car,
you have to have it serviced regularly
to make sure everything is in order.
