Defensive Cyber Security Researcher

Job Description Summary

Location: Tel-Aviv, Israel
#LI-Hybrid 3 days/week in office

Internal job title: Assoc. Dir. DDIT ISC Security Research

About the role:

The Defensive Cyber Security Researcher will be part of a new Think Tank group of security researchers that will challenge Novartis information security defenses, application security and data protection.
The Defensive Cyber Security Researcher will be responsible for participating in threat actor based investigations, creating new detection methodology and providing expert support to incident response and monitoring functions.
The focus of the Defensive Cyber Security Researcher is to detect, disrupt and eradicate threat actors from enterprise networks, including emerging AI-driven and AI-assisted threats. To execute this mission, the Defensive Cyber Security Researcher will use data analysis, threat intelligence, and cutting-edge security technologies — with a growing emphasis on understanding how AI can be weaponized against the organization and how it can be leveraged defensively.
The Defensive Cyber Security Researcher will identify and analyze patterns and changes in tactics, techniques and procedures used by attackers to attack Novartis IT infrastructure and management staff. The analysis will result in indicators of compromise, accurate understanding of the risk to Novartis IT infrastructure and prioritization of remediation efforts.

Job Description

Key Responsibilities:

• Hunt through huge number of signals to identify new emerging threats, dissect them and extract meaningful insights and indicators of compromise.

• Demonstrate adversary tactics to recognize and analyze malicious activity (techniques, tools and processes) based on a combination of behavioral activity and signature based analysis.

• Participate in "hunting missions" using threat intelligence, analysis of anomalous log data and results of brainstorming sessions to detect and eradicate threat actors on the Novartis network.

• Provide expert analytic investigative support of large scale and complex security incidents.

• Perform analysis of security incidents for further enhancement of alert catalog; perform in-depth static and dynamic malware reverse engineering; preform ad hoc memory and disk forensics.

• Produce detailed technical reports in support of malware / other hunting investigations.

• Review alerts generated by detection infrastructure for effectiveness and recommend improvements.

• In collaboration with the Security Operations Center: Develop dashboards and reports to identify potential threats, suspicious/anomalous activity, malware, etc.

• Research and assess AI-specific security risks to the organization, including adversarial use of AI models, prompt injection attacks, data poisoning, shadow AI adoption, and LLM-assisted threat actor operations; translate findings into actionable defensive guidance and detection rules.

• Collaborate with Cyber Threat Intelligence (CTI) teams to operationalize intelligence feeds, enrich hunting missions with external and internal threat data, and contribute research outputs (IOCs, TTPs, adversary profiles) back into intelligence pipelines.

Essential Requirements:

• 5+ years of experience in Incident Response / CERT team or 5+ years of experience with malware investigations.

• Critical understanding of the cyber attacker kills chain elements, with particular emphasis on attack objectives.

• High familiarity and experience with Active Directory (AD) and Entra ID / Azure AD security — including AD attack paths (Kerberoasting, pass-the-hash, DCSync, Golden/Silver Ticket), BloodHound-based graph analysis, AD tiering models, and Conditional Access Policies; ability to identify misconfigurations that lead to privilege escalation and lateral movement.

• Solid understanding of AI security risks and their organizational impact, including adversarial machine learning, prompt injection, data poisoning, shadow AI risks, and the use of generative AI tools by threat actors; ability to advise the organization on AI-related threat exposure and contribute to AI governance from a security perspective.

• Proven ability to work effectively with Security Operations Center (SOC) teams: including joint detection engineering, alert tuning, escalation workflows, and acting as a subject matter expert during high-severity incident response; experience bridging the gap between research depth and SOC operational tempo.

• Experience working with Cyber Threat Intelligence (CTI) teams: consuming and operationalizing intelligence products, contributing research outputs as structured intelligence (IOCs, TTPs, adversary profiles), and participating in joint threat briefings and intelligence-driven hunting operations.

• Good familiarity with Red Teaming tools and operations, understanding of Wireshark, Cobalt Strike and more

• Advanced programming skills with scripting languages such as Python/Perl/Ruby.

• Familiarity with the current nation-state (“APT”) threat landscape and the various actors and groups.

• Very strong team and interpersonal skills along with the ability to work independently and achieve individual goals, with effective oral and written communication skills.

Desirable requirements:

• Relevant Technical Security Certifications (GIAC, EC-Council, Offensive Security, etc.)
