China-linked Fire Ant compromised Cisco IOS XR routers and TACACS servers, then rewrote the logs to stay invisible.
The routers logged only "Health" heartbeats, so liveness checks passed while everything else vanished.
Off-host logging catches it.

SMOKE#SCREEN disables Windows Defender, then installs a validly signed ScreenConnect agent as its backdoor.
Your signature allowlist trusts it. The tampering it does first is what gives it away.

Device-code phishing rose ~1,500% in 2026. It steals Microsoft 365 tokens after you sign in, so MFA and passkeys do not stop it.
Hits Entra ID tenants.
Fix: block the device-code flow in Conditional Access, alert on every use.

Malware can copy the device key behind Google Chrome passkeys and sign in as you, even with two-factor required, Unit 42 showed.
The hole: sites that never check the "user verified" bit.
Fix: validate that flag server-side.

🔴 EXPLOITED
Cisco Secure Firewall Management Center ships a hardcoded password that lets a stranger log in with no credentials (CVE-2026-20316).
It is being exploited now and sits on CISA's must-patch list.
Apply the hotfix, then check logs for signs of entry.

🛠️ Tool
===================
numbat is an endpoint visibility tool for AI agent activity, developed by perplexityai. It provides local detection, optional pre-action blocking, and forensic reconstruction of agent sessions across desktop, CLI, IDE, and gateway surfaces.
🔹 Key Features
The tool observes supported agents through local hooks and plugins, OTLP/HTTP log exporters, and on-disk session artifacts. Live and at-rest activity is normalized into a single event model and evaluated by a CEL rule engine. Detection runs entirely locally. Records can be written to stdout or a local file, with optional HTTP delivery.
• Live monitoring via hooks, plugins, and OTLP/HTTP exporters
• Local detection with built-in CEL rules, multi-step sequence rules, and custom YAML rules
• Optional blocking through supported synchronous pre-action hooks (disabled by default; only rules marked enforce: true apply)
• Forensic reconstruction from on-disk session artifacts without prior numbat instrumentation
• Versioned NDJSON records for events, findings, enforcement decisions, indicators, and scan summaries
• Read-only artifact scanning with secret redaction; raw transcripts never included in normal output
• Inventory and investigation tools for agent discovery, per-session timelines, and portable case bundles with SHA-256 manifests
• Single-binary distribution for macOS, Linux, and Windows, built without cgo
🔹 Technical Implementation
Installation is straightforward: download a release or use go install github.com/perplexityai/numbat/cmd/numbat@latest. Read-only inventory commands (numbat agents, numbat scan) do not install hooks or modify agent configuration. Live monitoring requires numbat hook install --agent --emit all, which starts in monitor-only mode.
Hook trust requirements vary by agent and scope. For Codex user hooks, operators must review and trust the hook definition in /hooks or Settings > Hooks. Managed hooks are trusted by policy.
All shipped rules are monitor-only. To enforce a detection, operators copy the shipped YAML into a controlled directory, add enforce: true, bump the version, then install with --enforce.
🔹 Use Cases
• Security teams needing visibility into what AI agents execute on developer endpoints
• Forensic reconstruction of past agent sessions without prior instrumentation
• Compliance auditing of agent actions with versioned NDJSON records
• Incident response with portable case bundles and SHA-256 manifests
🔹 Limitations
Blocking is limited to supported synchronous pre-action hooks only. The coverage matrix is authoritative for each host and surface. hook status verifies configuration, not execution or delivery. Tool has not been independently tested.

More than 30 Minnesota water systems were disrupted in one coordinated 48-hour attack.
Hitting that many small utilities at once is the mark of one shared weakness, not 30 break-ins.

It used no new exploit. A data service left with no password got it in.

Thank you to @onepict@chaos.social and @jwildeboer@social.wildeboer.net for this.
My primary curiosity for digging in here wasn't the vendor or anti-vendor politics point, or the freedom-of-coder-communities-to-organize point, but rather… how exactly are they enforcing this? #AI #antislop #slop #detection #FOSS

Three separate July studies land on the same finding: AI coding agents can be made to run attacker code with the developer's own privileges.

Google Dialogflow CX had a flaw where one 'edit' permission on a chatbot ran code across every Code Block agent in the project, and reached cloud credentials.
