Hans joined CHT Security as senior consultant in January 2018. With 10 years of experience in cybersecurity , he specializes in hacking techniques, red team, web security, and network penetration testing, and has discovered multiple critical CVEs. As a professional certified by several international credentials, including CEH, CHFI, GWAPT, OSCP, he aspires to help world peace and to enable security personnel to leave office early to work from home.
In the first half of 2020, the COVID-19 pandemic has given rise to the need of working from home. While IT engineers strived to deploy VPN architecture so their colleagues could work remotely, a backdoor has also been opened for hackers to directly access the corporate intranet.
Hans and his team have observed ransomware attacks in major industries during the second half of 2020 and discovered this phenomenon, and in this speech, he will be sharing how his team performed red teaming exercises to intrude Active Directory and to establish backdoor, hoping to prevent companies from falling into the same trap.
