Director, Cyber Threat Intelligence Lab
Dragos Gavrilut is a threat research director at Bitdefender, managing a team of 180+ people that develop machine learning algorithms design for threat detection, event correlation and post-breach threat hunting rules, anomaly detection and user analytics , all of them in the context of NTA/EPP/EDR/XDR space. His team is also specialized in risk analytics, forensics and IOT analysis. He is also an associate professor at the Alexandru Ioan Cuza University of Iași, where he received his Ph.D. in 2012, with the thesis entitled Meta-heuristics for Anti-Malware Systems. He received his B.Sc. and M.Sc. in computer science from the same university, in 2004 and 2006, respectively.
Andrei joined Bitdefender in October 2008 as a junior virus researcher. Initial responsibilities included reverse engineering of malicious samples, adding signatures for malicious files, developing disinfection routines and developing code-similarity methods and systems. He joined the R&D team in November 2011 as an Introspection Research Lead, and he laid the foundation for today's cutting edge Hypervisor Memory Introspection technology. During his work on this project, he authored several academic papers, spoke at several industry-leading conferences, including BlackHat, demoed the HVMI technology at events such as Citrix Synergy and VMworld, and worked on more than 10 patent applications. Currently, Andrei is a PhD student and an associate teacher at the Technical University of Cluj-Napoca, and he leads the team responsible for developing the open-source HVI technology. His main interests are everything low-level related, such as reverse-engineering, kernel security, hypervisors and hardware-based security (especially side-channels and speculative execution attacks), and security-oriented ISA extensions.
Senior Technical Manager
In 15+ years of experience in Information Security, all with Bitdefender, Dan has sought to gain a holistic view of this complex topic through exploration of multiple aspects – technical (operating systems internals, networking, hypervisor technologies), non-technical (auditing of information systems, security management), defensive (malware analysis, development of advanced detection and prevention technologies) and offensive (penetration testing, vulnerability analysis).
He obtained several InfoSec certifications (CISSP, CEH, CISA, OSCP, OSCE) and, since 2016, he holds a PhD in Computer Science from Technical University of Cluj-Napoca (TUCN). His current role with Bitdefender involves managing a team of security researchers and software engineers that develop run-time behvior-based malware detection and dynamic exploit detection techniques. He teaches Information Systems Auditing and Incident Response & Forensics courses at a Master-level program in TUCN. He is the author / co-author of five scientific papers and five US patents regarding low-level hypervisor security.
Cybersecurity Technology Research Manager
Silviu Sofronie is leading the gathering and analysis of Threat Intelligence feeds, from Honeypot deployments to Law Enforcement & CERT collaborations. He owns 500+ honeypots, providing real-time feeds on threats that are emerging, as well as monitoring known threats to observe any changes in behavior from good old hacks and hackers. Darknet and emerging underground threats are a new opportunity to research the way hackers operate and anticipate their moves.
