The SolarWinds breach set the tone for industry conversation about enterprise threats throughout 2021 and surfaced new questions on third-party relationships and supply chain security, one of the prevailing themes of this year’s show.
Another threat highlighted was the PrintNightmare vulnerability, a critical remote code execution flaw in Windows Print Spooler with huge enterprise risk implications. Discovered by three researchers from Sangfor Technologies in China and explored in depth at Black Hat, PrintNightmare makes privilege escalation trivial for attackers on just about any system running Windows Print Spooler.
Active Directory threats were also in the spotlight. According to security practitioners at Mandiant Consulting who presented at Black Hat Asia earlier this spring, some 90% of attacks their team investigates involve Active Directory in some form.
