Contact Yaniv Haliwa
The fastest way to reach Yaniv is the contact form on the home page, which delivers directly to his inbox. No public email address is published on this site, deliberately: the form gives a working reply-to address without exposing a mailbox to scrapers.
What to get in touch about
Messages that get a reply generally fall into one of these categories:
- Penetration testing and security assessment engagements, where a defined scope and authorisation exist.
- Security research collaboration, including bug bounty work, coordinated disclosure and joint writeups.
- Python security automation, tooling and workflow automation projects.
- Roles and contract work in offensive security, application security or security engineering.
- Questions about his published tools — RootShell, CyberTools, CyberDict, WatchWise, WifiSec and the Linux admin toolkit.
What not to send
Unsolicited bulk mail, SEO and link-building offers, and automated outreach are ignored. Requests to test systems you do not own or have written authorisation for will be declined. Please do not send exploit code or sensitive vulnerability detail in a first message; open the conversation first and agree a secure channel.
Response expectations
This is a personal inbox, not a staffed support desk. Genuine enquiries usually receive a reply within a few days. There is no service-level agreement, no ticketing system and no phone number.
