Real Folks of Cyber | Pearce Barry | Day in the Life
Pierce Barry, Director of Security at Pura, leverages over 30 years of technical experience, including 11 years in full-time security, to navigate the industry without a rigid career plan. His background spans mechanical engineering, kernel development, and embedded systems before he joined Rapid7 in 2016 to work on the Metasploit Framework. Barry contrasts his current role at a 10-year-old company with 200 employees against the siloed structures of major FANG firms, emphasizing how his diverse history in intrusion detection and prevention systems enables him to manage broad security responsibilities. He attributes his career trajectory to networking and serendipitous opportunities rather than long-term strategic planning.
The attack that hijacked Claude Code came through Sentry. Datadog, PagerDuty, and Jira have the same exposure.
A single crafted Sentry error event hijacked Claude Code with an 85% success rate in controlled testing, executing attacker code with full developer privileges while bypassing all standard security layers including EDR, WAF, and firewalls. Tenet Security identified 2,388 organizations with publicly exposed Sentry credentials, creating a systemic vulnerability known as agentjacking that affects tools like Datadog, PagerDuty, and Jira. Surveys from 2026 reveal that only 34% of organizations apply equivalent security controls to AI agents as they do to human users, leaving 88% of agents exposed to confirmed or suspected incidents. The core failure lies in the runtime gap where authorized API calls and trusted diagnostic outputs allow malicious instructions to execute silently without triggering any alerts.
