About the Role
Check Point Software Technologies is urgently seeking a Senior Security Researcher to investigate and neutralize the active exploitation of CVE-2026-50751, a critical authentication bypass vulnerability in its Remote Access VPN and Mobile Access solutions. This role has been created in direct response to confirmed attacks by a Qilin ransomware affiliate, who leveraged the zero‑day flaw to compromise corporate networks. The position requires deep expertise in VPN security, exploit analysis, and ransomware threat intelligence, and will play a pivotal part in hardening Check Point’s products against emerging cyber threats.
Key Responsibilities
- Reverse‑engineer the Qilin ransomware affiliate’s exploit chain targeting CVE-2026-50751 to understand attack vectors and lateral movement techniques.
- Develop and validate proof‑of‑concept code to replicate the authentication bypass, then collaborate with product engineering on permanent patches.
- Create and tune intrusion detection signatures (Snort, YARA, Suricata) to detect exploitation attempts across customer environments.
- Lead incident response investigations for Check Point enterprise clients affected by this zero‑day, providing root‑cause analysis and remediation guidance.
- Publish internal threat intelligence reports and, where appropriate, contribute to public advisories in coordination with the company’s PR and legal teams.
- Mentor junior analysts and participate in the on‑call rotation for critical vulnerability escalations.
- Stay abreast of ransomware affiliate tactics, techniques, and procedures (TTPs) to proactively identify new exploitation methods.
Requirements
- 5+ years of hands‑on experience in offensive security, vulnerability research, or malware reverse engineering.
- Deep understanding of VPN protocols (IPsec, SSL/TLS), authentication mechanisms, and Check Point Security Gateway architecture.
- Proficiency with disassemblers (IDA Pro, Ghidra), debuggers, and scripting languages (Python, Bash, PowerShell).
- Familiarity with ransomware operations, initial access broker ecosystems, and the MITRE ATT&CK framework.
- Industry certifications such as OSCP, OSCE, GREM, or CISSP are strongly preferred.
- Excellent written communication skills, with the ability to document findings for both technical and executive audiences.
Compensation & Benefits
- Competitive base salary supplemented by performance‑based bonuses and equity grants.
- Comprehensive health, dental, and vision insurance with coverage for dependents.
- Flexible remote‑first work policy, with the option to work from Check Point offices worldwide.
- Annual budget for professional development, including conferences (Black Hat, DEF CON), training, and certifications.
- Generous paid time off, parental leave, and wellness programs.
