applied security research

Wesley Neelen

Wesley has over 7 years’ experience in the offensive security area working as a penetration tester. Next to his work assessing the security of infrastructures, he spends time researching trends within IT security and on developing defensive measures. Wesley also likes to actively assess the security of home automation, internet of things and 'smart' innovations. Some examples: one of the vulnerabilities discovered by Wesley, is a remote command execution (RCE) vulnerability in the Fibaro home center appliance. The vulnerability allowed to remotely obtain root access on the Fibaro device whenever the web interface is reachable. Another vulnerability that Wesley discovered is a vulnerability within a smartwatch cloud that disclosed the location history of about 300.000 of its users. Both vulnerabilities were fixed after contacting the owners of the products, making the world a little bit safer.
