The annual pilgrimage to Las Vegas for Black Hat USA and DEF CON never disappoints, serving as a vital pulse-check on the cybersecurity landscape. This year’s events, wrapping up in early August 2025, amplified the dual-edged role of AI in security, the practical hurdles of SBOM adoption, and the power of cross-sector partnerships to fortify open-source ecosystems. Drawing from onsite conversations with CISOs and experts, as explored on [techguideonline.com], these gatherings revealed actionable insights for leaders aiming to stay ahead of evolving threats. In an era where software underpins everything from municipal services to enterprise operations, the emphasis on resilient, collaborative strategies couldn’t be timelier.
AI’s Dual Role: From Vulnerability Hunter to Defender’s Ally
Artificial intelligence dominated discussions at both Black Hat and DEF CON, emerging not just as a threat vector but as a transformative tool for proactive security. At DEF CON’s AI Cyber Challenge (AIxCC), hosted by DARPA, teams showcased AI systems capable of autonomously detecting and patching vulnerabilities in open-source code a stark contrast to manual processes that drag on for weeks.
Michael Brown from Trail of Bits spotlighted their cyber reasoning system, Buttercup, which automates vulnerability discovery and remediation at scale and low cost. Supported by DARPA and ARPA-H, Buttercup demonstrated how AI can tip the scales toward defenders by slashing remediation timelines. “Government-sponsored competitions like the AIxCC are incredible opportunities for us to make game-changing advances in cybersecurity that benefit everyone,” Brown shared. Yet, caveats abounded: CISOs raised flags on AI’s reliability, data privacy risks, and the need for repeatable outcomes in high-stakes environments.
Expanding on this, Black Hat sessions delved into agentic AI’s potential for incident response and threat hunting, with Microsoft urging organizations to rehearse AI-augmented plans only 26% currently do so. Comparisons to 2024’s focus on generative AI show a maturation: 2025 emphasized “agentic” systems that act independently, like those in Booz Allen’s Vellox Reverser for rapid malware analysis. As one CISO panelist at the 1Password discussion noted during DEF CON’s Blue Team Village, “AI isn’t hype anymore it’s about embedding it into SOC workflows to combat fatigue.”

SBOM Adoption: Bridging the Gap from Promise to Practice
Software Bills of Materials (SBOMs) took center stage at Black Hat, with panels dissecting their role in supply chain risk management amid joint US guidance from allies. While SBOMs promise transparency into software components, CISOs highlighted implementation roadblocks: educating devs, standardizing formats, and integrating into CI/CD pipelines.
Stephanie Domas, CISO at Canonical, captured the sentiment: “SBOMs continue to show great promise and are already starting to deliver on some of their expected benefits, but still face some implementation challenges. Accuracy of SBOM generation, adequate reflection of applied patches, and complex versioning situations when dependencies have been forked are all growing pains the industry as a whole will have to work through.” Automation emerged as a recurring fix, with calls for better tools to ensure SBOMs stay current and actionable for vulnerability prioritization.
This year’s talks built on 2024’s foundational push, now focusing on real-world hurdles like forked dependencies in open-source forks. At DEF CON’s villages, hands-on demos illustrated SBOM pitfalls in containerized environments, echoing AWS research on shared EC2 trust domains. The takeaway? SBOMs aren’t a silver bullet but a foundational step pair them with continuous monitoring to manage the “risk surface” beyond mere attack vectors.

The Power of Partnerships: Government, Industry, and Open Source Unite
Collaboration was the event’s undercurrent, with a palpable hunger for tighter ties between government agencies like DARPA and the open-source community. DEF CON’s AIxCC exemplified this, blending federal funding with hacker ingenuity to yield publicly available tools. Derek Zimmer from the Open Source Tech Improvement Fund (OSTIF) stressed: “Partnerships between the open source community and the federal government can turn good ideas into deployed defenses. Funding, openness, and competition helped accelerate tools the whole community can potentially use.”
Black Hat’s CISO Summit reinforced this, tackling board-level communication and risk governance amid policy talks from NSA’s Bailey Bickley on industrial base protection. Events like these foster relationships that translate to real-world wins, such as OSTIF’s funding models yielding ecosystem-wide benefits. Compared to last year, 2025 saw more emphasis on public-private dynamics, with warnings from former officials like Gen. Nakasone on government disengagement’s risks to critical infrastructure.

Emerging Trends: Zero Trust Scrutiny and Agentic AI’s Rise
Beyond core themes, CISOs buzzed about zero trust’s flaws AmberWolf’s DEF CON report slammed ZTNA for “always trusting, never verifying.” Agentic AI stole the show, with panels on its use in DoS attacks (Win-DDoS) and ethical governance. Fortinet’s CISO Carl Windsor joined Vercel and Salesforce peers to unpack the modern CISO’s burdens, from IR readiness to AI accountability.
Nonprofit Cyber’s stage presence at both events underscored community-driven defense, while Splunk’s guide emphasized networking’s value. As one attendee quipped in a CISO2CISO post, “From AI summits to hardware exploits, Black Hat 2025 was a call to action.”
FAQs
What were the top AI discussions at Black Hat and DEF CON 2025?
Focus centered on agentic AI for vulnerability patching (e.g., DARPA’s AIxCC) and defenses, balanced against risks like prompt injection in tools like ChatGPT Connectors.
Why are SBOMs challenging for CISOs to implement?
Issues include accuracy, patch reflection, and versioning complexities; solutions lie in automation and OpenSSF collaborations for standardized integration.
