offensive security & incident response — hackerseye
I break in for a living — and I'm the one they call after someone else did.
## WHOAMI
Six years on every side of the same vulnerability
Security researcher at HackersEye. I split my time between offensive work — penetration testing, red team engagements, external attack surface research — and incident response. Web applications, infrastructure, internal networks, IoT, mobile.
I got here the long way. Incident response at Cellcom, then two years of application security research at enso.security, where I shipped to production. Then Profero, where I ran incident response engagements end to end, including the SysAid zero-day exploited by Lace Tempest.
So I've seen the same vulnerability from three sides: the scanner that should have caught it, the pentest that finds it anyway, and the incident where someone already used it.
## DISCLOSED VULNERABILITIES
Priority Portal Generator — 9 CVEs
Research by Roei Hadashi and Dean Bar at HackersEye. Portal Generator served the internal ERP server address, the gateway in front of it, the application secret, the licence key, and a working API username and password to every visitor before login. Credential encryption ran client-side in JavaScript, so it protected nothing.
