Sooraj Sathyanarayanan

I am a Program Manager at Brave and a cybersecurity and privacy researcher. I build open-source security tools and write practical guides for understanding how software handles data. I hold an MS in Cybersecurity from Northeastern University.

Selected projects

Project What it does
Site Behavior Lab Records requests, cookies, storage, browser signals, and consent behavior during automated website visits. Reports connect findings to recorded evidence and explain scan conditions and coverage limits.
Brave Nightly Change Tracker A public review interface for merged brave/brave-core pull requests and changes relevant to Brave Nightly.
Trace Uses Rust and WebAssembly to check iPhone sysdiagnose archives for known spyware indicators locally in the browser. Reports distinguish findings from incomplete coverage; a scan cannot establish that a device is free of compromise.
Metadata Remover Inspects and removes structural metadata from supported images, documents, audio, and video locally in the browser, then checks cleaned files again. It does not remove sensitive information visible in the content itself.
QRWarden A pre-release QR inspector that displays decoded content and URL properties without visiting the destination during inspection. It does not certify that a link is safe.

Security guides

I write and curate practical guides for Google account security, iOS hardening, GrapheneOS, and GitHub security. More work is collected on my projects page.

Selected contributions

Some examples of my accepted contributions to other projects:

Research

I coauthored three conference papers: two indexed in IEEE Xplore and one published in Springer conference proceedings.

My research on the privacy of fitness wearables received grant support from the Ludlow Institute through Timechain Consulting.

Selected coverage

Community and teaching

I founded null NEU at Northeastern University and null Boston as a separate city chapter. At null NEU, I served as Chapter Lead / President and later as an advisor, organizing cybersecurity education and mentoring students. The official chapter page lists me among its leaders, and my null Community profile records selected speaking sessions.

I also previously taught Digital Forensics and Incident Response as adjunct cybersecurity faculty at Lasell University.
