An agent is dangerous only when it has all three at once: access to private data, exposure to untrusted tokens, and an exfiltration vector. Before shipping, architect to break at least one leg. Strip the outbound channel, sandbox the untrusted input, or scope away the sensitive data. Defense-in-depth backs it up, but the trifecta check is the first gate, and it catches the manipulation WAFs and input validation can't (source).

SARC-DQ found competent agents converted freshness/lineage/provenance defects into costly actions about 60% of the time, with both data-quality flags and the agents' own hedging detecting them at chance. The conversion rate was flat across four model tiers spanning a 15x price...
A public DSN. That's all the attacker needs. Not your credentials, not a compromised dependency, not a phishing link. The same write-only Sentry key that's sitting in your frontend bundle right now, by design, so the browser can report errors. Tenet Security and the Cloud Secu...
A single passing eval hides nondeterminism. Measure all-runs consistency with pass^k (the probability all k runs pass) so flaky agents get caught before release. Pair it with a judge calibrated against a human gold set, and grow that golden set from real production traces so t...
Because agent code is generated at runtime and can't be reviewed before it runs, the 2026 model treats it as arbitrary adversarial code and picks one of three primitives by threat model: Firecracker microVMs for regulated data, gVisor for compute-heavy multi-tenant, V8 isolate...
The binding rule for parallel coding agents, deviate and race conditions come back. Budget ~5 GB disk per worktree (six agents burned 9.82 GB in 20 minutes), and throughput degrades past 5–7 agents from rate limits and the human cost of reviewing six PRs at once. Gate each tas...
Agent Intent-Based Access Control compares an agent's reasoning, tool calls and data access against its originally assigned task with adjustable sensitivity, flagging or blocking anything outside scope. It evaluates entire sessions rather than individual requests, specifically...
