Liam O’Murchu is a director with the Security Technology and Response group at Symantec, a division of Broadcom. Over
the past 15 years, Liam has investigated and responded to the most sophisticated cyberattacks ever –
from professional cybercriminals targeting financial institutions to government-backed threats targeting
critical infrastructure. He has worked with law enforcement to pursue malware authors and disrupt
botnets, and his analysis and testimony have helped secure lengthy cybercriminal convictions. His
analysis of Stuxnet's objective to disrupt uranium enrichment in Iran is recounted in the book
Countdown to Zeroday. He is currently spearheading the effort to combine threat-specific knowledge
with behavior analysis to automate attack surface reduction.
