GPT-5.5-Cyber built a zlib fuzzing lab in a day

Trail of Bits describes supervising GPT-5.5-Cyber as it built ASan and UBSan variants, derived seed corpora, and wrote fuzz harnesses for roughly a dozen zlib entry points in one day. The useful result is the workflow and its emphasis on reachability and reportability; vulnerability details remain under coordinated disclosure and the speed comparison is the authors' estimate.

How We Turned AI's 'Web Browsing' Into a Gateway for Targeting 1B+ Users

A systematic study of server-side browsers used by AI search and web-browsing services reports remote-code-execution paths in six leading services with a combined user base above one billion. The work covers domain-allowlist bypasses, JavaScript-restriction evasion, remote browser fingerprinting, service disruption, output manipulation, and server compromise.

Internal coding-agent monitoring: retrospective alerts have prevention limits

OpenAI’s March report describes asynchronous review of internal coding-agent conversations, reasoning and tool activity, with suspicious interactions escalated to human responders. The reported system reviewed interactions within 30 minutes of completion; blocking actions before execution was future work. Matching known employee escalations did not establish the false-negative rate on open-ended traffic.

Validate security invariants across decoding and normalization steps

OpenAI’s Codex Security explanation uses a redirect-validation example to show how a security check can stop constraining input after decoding or normalization. Its described workflow starts from repository context and trust boundaries, reduces hypotheses to testable code slices, and uses sandbox execution or constraint solving to validate findings.

Self-hosted agent evaluation: measure concurrency and cost per completed task

Steven Latré describes comparing coding agents across models, harnesses and GPU configurations using SWE-bench Pro. The method measures resolved tasks, latency, concurrency and hardware occupancy together: similar task scores can hide different token use and GPU time. The talk covers one workload and promises a broader public dataset; its break-even percentages are not portable purchasing guidance.

ARTEX intrusions: rotate exposed signing keys and audit cloud command privileges

CrowdStrike reports a human-directed ARTEX campaign against more than 200 organizations, with post-exploitation confirmed at nine. Recovered transcripts link agent workflows to unsigned SAML assertions, cloud metadata access, unrotated mail keys and endpoint coverage checks. The target count is not a breach count, and the second commercial model remains unidentified.

Agent crash recovery: retain completed work and test in-flight retries

Shy Ruparel’s payout example keeps workflow decisions deterministic and records model calls, tool results and human approvals in durable history. A worker restart can reuse completed activities while an in-flight activity may retry. The talk uses synthetic payments and switches to a recording after the live restart stalls; it does not prove exactly-once external effects.

Code-review evaluations: test business rules beyond the changed lines

Sonar’s ticketing-app workshop demonstrates three review cases: refunding a transferred ticket, displaying a fee outside the advertised total, and scanning one ticket twice. It adds written business rules and a required CI check before demonstrating automated fixes. These are prepared examples of verification gaps, not evidence of general reviewer accuracy or safe autonomous merging.

PHP2Shell response: investigate identity access after firewall compromise

Dream’s updated investigation identifies a PHP2Shell and kernel-exploit chain against exposed PAN-OS management interfaces. Unit 42 says it verified the attacker’s tooling and reported results. Recovered artifacts show tunnels, extracted LDAP credentials and directory enumeration; later password spraying and account-creation outcomes remain unknown. AI assistance is an assessment, not proof of autonomy.

Agent improvement loops: verify failure cases before adding them to regression data

Fuad Ali’s workshop follows a toy-shopping agent from trace review to a failure dataset, evaluator, proposed fix and comparison run. A planted filter bug produces redundant searches; the walkthrough checks whether the fix removes that behavior without breaking other requirements. Human review remains central to confirming issues, curating examples and judging fixes. Demo scores are not general release thresholds.

Write an agent evaluation by defining one observable pass-or-fail criterion

SallyAnn DeLucia’s workshop turns travel-agent traces into an evaluation dataset. It defines concrete success and failure criteria, selects the spans containing the required evidence, maps their fields into a judge prompt and inspects labels with explanations. Human annotations then check judge agreement. The exercise is a starting workflow, not evidence that automated scores are reliable by default.

AI observability checks: verify restored data and inspect judge outputs

Al Chen describes two failures that status dashboards can miss: a successful backup job can restore stale data, and a judge’s explanation can repeat sensitive input even when the main UI is redacted. He proposes checking restored records and controlling which judge outputs persist. A second judge or a redacted display alone does not establish that every data path is safe.

Agent calculations: trace assumptions, code changes, and review decisions

Francesco Galletta and Felippe Felisola Caso use a wedding-budget demo to connect tested calculations with evidence lineage. Inputs are distinguished as sourced facts, assumptions, or interpretations, and reviewer challenges feed back into the plan. Repeatable arithmetic can still use wrong assumptions or changed code. The speakers present a design example in a personal capacity, not a verified Monzo deployment.

Managed agents: test credential scope and what an interrupt actually stops

CJ Avilla and Harrison Stall demonstrate controls around managed multi-agent work: scoped tools, network limits, vault credentials, budgets, and interrupts. Official documentation adds crucial limits: access to an allowed host does not restrict every operation, echoed responses can expose secrets, and some in-flight work can finish after a stop. These controls require validation; the demo does not prove safe operation at scale.

Langflow MCP execution flaws: patch the execution boundary and restrict access

Langflow advisories describe command execution through MCP stdio configurations. Version 1.9.0 addressed one API path; the related advisory identifies 1.10.3 as the fix covering flow configurations and the execution boundary. Default auto-login can expose the authenticated functionality without credentials. Reported honeypot activity shows attempted exploitation, not a count of compromised deployments.

Model cost optimization: compare repeated runs and adjudicate quality changes

Alvin Pane describes measuring baseline variation before changing prompts, caching, or model size. Repeated production and candidate runs help distinguish normal inconsistency from regressions, followed by review of changed outcomes. The synthetic example illustrates a testing workflow, not verified savings. Agreement between runs measures consistency and can still conceal a shared wrong answer.

Graph-based fraud evaluation: preserve time boundaries and compare at a fixed alert budget

Somya Rai and MD Sharique describe adding graph embeddings to an XGBoost fraud classifier. Their engineering walkthrough covers user-history sampling, disjoint monthly graphs, past-only neighbors, training-only preprocessing, and cached representations for serving. The transferable method is to check temporal leakage and compare detection at the same analyst alert budget. Proprietary portfolio results and projected financial gains are not independently verified.

Agent review: verify artifacts, reconcile sources, and challenge conclusions

Corey Gallon separates three checks: verify the delivered artifact, reconcile independent extractions against original sources, and challenge conclusions with fresh reviewers. His companion article and public agent-review instructions make the workflow inspectable. A matching fingerprint proves artifact identity, while balanced totals can still hide shared errors. The reported session analysis measures failures in one sample, not the effectiveness of the review method.
