László has more than 10 years experience in information security (penetration testing, security audit, incident response). As a researcher his focus is Oracle Database security. He published several research papers and tools in this subject. László is the developer of the woraauthbf tool, which was one of the fastest Oracle password crackers at the time of its release. He also released several unique research papers about vulnerabilities of the Oracle authentication protocols and post-exploitation techniques. His name was mentioned in several CPUs released by Oracle. You can check out the technical deepness of his presentations at www.soonerorlater.hu:
