Hi, I'm Alisha Chaudhary 👋

Cybersecurity Analyst | Threat Intelligence | Vulnerability Assessment | CVE Research | Security Research


About

I build practical security tools, investigate published vulnerabilities through controlled experimentation, and translate technical findings into actionable defensive intelligence.

My work focuses on threat intelligence, vulnerability assessment, CVE research, and security automation. Rather than accepting published security claims at face value, I enjoy validating them through reproducible experimentation, careful measurement, and transparent reporting.

With a multidisciplinary background in Computer Applications, Biochemistry, and Chemistry, I approach cybersecurity as an evidence-driven discipline: formulate a hypothesis, build a controlled environment, measure the outcome, and document findings that others can reproduce.

Statistical Validation Study of CVE-2016-6210

Research Summary

Objective: Re-evaluate CVE-2016-6210 on a modern default OpenSSH deployment.

Method: Manual probing, Hydra, and Metasploit were used to collect authentication timing measurements. Welch's t-test and Cohen's d were applied to distinguish genuine timing signals from measurement noise.

Finding: No statistically significant timing difference was observed on the tested Ubuntu Server default PAM configuration, indicating that the documented timing side-channel was not reproducible under these conditions.

This project re-investigates CVE-2016-6210, an OpenSSH username enumeration timing side-channel, to determine whether it remains observable on a modern Ubuntu Server configured with default PAM authentication.

Rather than relying on visual inspection of response times, the project evaluates timing measurements statistically. The outcome is a reproducible validation study demonstrating that carefully supported negative results can be as valuable as positive findings when assessing the current security posture of published vulnerabilities.
