Lawmakers call for investigation into impact of CISA staffing cuts

Democratic lawmakers asked the GAO to investigate how CISA's roughly one-third workforce reduction affects its mission and critical-infrastructure protection.

Democratic lawmakers led by House Homeland Security ranking member Bennie Thompson asked the Government Accountability Office to examine how recent staffing cuts at CISA affect its ability to protect critical infrastructure and respond to cyber and physical threats. Nearly 1,000 CISA employees have been fired or quit since the Trump administration began, and acting director Nick Andersen plans to hire 300. The letter also flags the FY2027 budget proposal to eliminate nearly 900 additional positions and cut more than $700 million from the agency. CISA has had no confirmed director since Jen Easterly departed, and GAO confirmed it received the request.

CISA review makes the case for eliminating vulnerability classes

CISA's FY2024-2025 vulnerability review urges eliminating recurring vulnerability classes, finding 41.5% of 2025 KEV entries map to persistent 'stubborn weaknesses'.

CISA's Vulnerability Review for fiscal years 2024 and 2025 found most compromises stemmed from opportunistic exploitation of known, exposed vulnerabilities rather than nation-state zero-days or advanced tradecraft. The review found 41.5% of 2025 KEV catalog entries map to 'stubborn weaknesses' - injection flaws, improper input validation, memory-safety failures, path traversal and broken access control - recurring on the CWE Top 25 since 2019. CISA advocates Secure by Design practices, vulnerability class elimination, and buyer-driven 'Secure by Demand' contract requirements, while warning that AI-enabled vulnerability discovery will soon accelerate exploitation.

CISA Warns Water Utilities: Find Your Exposed PLCs Before Attackers Do

CISA urged water utilities to secure internet-exposed PLCs after July 2026 attacks compromised over 100 US water and wastewater systems, suspected Iran-linked.

CISA's exposure-reduction guidance, published August 21, follows July 2026 attacks in which threat actors remotely accessed PLCs connected directly through cellular modems, changed device IP addresses and passwords, and in some cases disabled alarms and shutdown processes without notifying operators. Iran is the suspected actor, though officials stopped short of formal attribution. CISA recommends routing remote access through centrally managed secure gateways, phishing-resistant MFA, unique credentials, and external scanning of industrial protocols such as Modbus, EtherNet/IP, DNP3, BACnet and OPC UA.

CISA Red Team Fully Compromised Two Critical Infrastructure Orgs

CISA red teams achieved full domain and cloud compromise at two critical infrastructure orgs; one SOC never detected the intrusion.

CISA advisory AA26-237A documents two simultaneous red team assessments. Organization A (Government Services sector) missed the intrusion entirely, as default credentials on a web app, ADCS ESC1 abuse, and thousands of false-positive alerts let the red team reach sensitive business systems and read SOC email. Organization B (Water/Wastewater sector) detected, isolated, and reimaged hosts quickly, but both orgs lacked Conditional Access for workload identities, and B still exposed DCSync, Golden Ticket, and OT network attack paths.

CISA decides weekly vulnerability bulletin isn't necessary anymore

CISA will discontinue its weekly vulnerability bulletin on September 28, pushing users toward KEV, alerts, and CVE data under risk-based prioritization.

CISA announced its weekly vulnerability bulletin will stop on Monday, September 28, as part of a shift from static CVSS severity scores to a modern, risk-based approach detailed in a June Binding Operational Directive. The directive prioritizes federal remediation based on exposure, exploitation evidence, control granted by exploitation, and whether exploitation can be automated. CISA directs bulletin subscribers to rely instead on its Known Exploited Vulnerabilities catalog, cybersecurity alerts and advisories, and the CVE catalog, requiring users to enable those subscriptions in GovDelivery or Granicus to avoid missing critical notices.

Water sector passes, government sector fails attempts to spot and halt simulated CISA attack

CISA red teamers compromised both a government and a water organization; water defenders detected and contained the simulated attack, government defenders did not.

CISA's red team gained initial access, elevated domain privileges, and lateral movement into sensitive business systems and cloud resources at an unnamed government organization, whose SOC ignored low- and medium-severity EDR alerts buried under thousands of false positives. A water organization's SOC quarantined phishing-compromised workstations within 2, 10, and 20 minutes, and later detected and isolated intrusions reaching the OT DMZ bastion host. Both organizations underestimated cloud risk, lacked Microsoft Conditional Access for workload identities, and had no process to revoke compromised access and refresh tokens. This is one of CISA's rare public red-team reports since 2023.

CISA Urges Organizations to Deploy Cyber Decoys to Detect Hackers Inside Networksnew

CISA's new guidance urges organizations to deploy cyber decoys like honeytokens and tripwires to detect attackers using valid credentials and living-off-the-land techniques.

CISA published 'Using Cyber Decoys to Strengthen Detection and Response' on September 16, 2026, advising decoy assets that appear legitimate but generate high-confidence alerts when accessed. It describes tripwires, breadcrumbs, and honeytokens such as fake usernames, passwords, API keys, and cloud access tokens, and recommends starting with low-complexity deployments like nonfunctional Active Directory accounts, decoy file shares, and isolated mimic hosts. The agency warns decoys must be segmented and nonfunctional to prevent attackers pivoting to real systems, and aligns decoy planning with MITRE Engage and ATT&CK.

AI agent authorization risks remain a gap in new NIST-CISA token security guidance

NIST and CISA release IR 8587 guidance on securing signed tokens, but AI agent authorization and delegation risks remain out of scope.

NIST, with CISA support, published 'Protecting Tokens and Assertions from Forgery, Theft, and Misuse' (NIST IR 8587), recommending continuous monitoring and tighter token lifecycle controls for SSO and API access. The guidance does not yet fully address AI agent identity, delegation chains, or prompt injection steering agents with valid tokens, and NIST says new or expanded standards are needed. Experts recommend treating AI agents as low-trust non-human identities, maintaining agent inventories, expiring credentials after task completion, and requiring human approval for high-risk actions. The report references shared-signal mechanisms like CAEP and RISC, and follows a May incident where a CISA contractor GitHub repository exposed AWS and GitHub tokens.

Severity Is Not a Strategy: What CISA BOD 26-04 Means for the Future of Federal Software Security

CISA's BOD 26-04 replaces severity-based federal patching with risk-based remediation deadlines of 3, 14, or 60 days.

CISA's Binding Operational Directive 26-04, released June 10, 2026, replaces BOD 19-02 and BOD 22-01 for Federal Civilian Executive Branch agencies and shifts remediation prioritization from CVSS scores to risk context. Agencies assess four factors: public exposure, KEV listing, exploit automatability, and whether exploitation grants partial or total asset control, resulting in 3-, 14-, or 60-day remediation windows or next-upgrade fixes. In CISA's first review at a large civilian agency, only 1% of vulnerabilities required three-day remediation while over 60% could wait for future system upgrades. The directive also requires forensic analysis when exploitation is suspected, and Checkmarx argues the same risk-based logic must extend upstream into software development and SBOM-driven exposure management.

CISA Warns Chinese AI Firms Extract Billions of Tokens From Claude, GPT, Gemini and Grok

CISA, NSA and FBI advisory says six Chinese AI firms extracted billions of tokens from Claude, GPT, Gemini and Grok via API proxies since late 2024.

A joint advisory from CISA, NSA and FBI alleges China-based AI companies including DeepSeek, Moonshot AI, Alibaba, MiniMax, StepFun and Z.AI harvested billions of tokens across millions of exchanges from Claude, GPT, Gemini and Grok variants since late 2024. Operators allegedly used API proxy 'transfer stations', account pools, bulk premium subscriptions and prompt injection or jailbreak-style requests to force models to reveal chain-of-thought reasoning. DeepSeek's R1 and V3 and Moonshot's Kimi-K2 and Kimi-K3 models reportedly benefited from the extracted data. CISA urged providers to add identity checks, monitor subscription-to-usage ratios, rate limit, and share infrastructure signals with cloud platforms.

CISA Red Team Compromised Two Critical Infrastructure Orgs, One Detected Nothing

CISA red teams fully compromised two critical infrastructure orgs with similar tradecraft; one detected nothing, the other contained phishing within minutes.

CISA advisory AA26-237A, 'A Tale of Two SOCs,' describes two simultaneous red team assessments of a Government Services organization and a Water and Wastewater Systems organization, both compromised to the domain level. Organization A never detected the intrusion, enabled by default credentials, a misconfigured AD CS template (ESC1), cleartext credentials, non-expiring static AWS keys, and over-permissioned Entra ID applications. Organization B detected and isolated phishing within 2-20 minutes, though the red team still reached krbtgt via DCSync from cleartext SCCM credentials. CISA attributes the outcome gap to people and processes rather than the security tools themselves.

CISA's logging guidance works beyond government

CISA released its Logging Reference Architecture in August 2026 to help federal agencies meet OMB M-26-14 logging requirements, usable as a benchmark by critical infrastructure operators.

CISA's Logging Reference Architecture (LRA), released in August 2026, helps US federal civilian agencies satisfy logging requirements in OMB Memorandum M-26-14 and explicitly encourages critical infrastructure operators to use it as a benchmark. The framework is organized around continuous event monitoring and threat hunting, investigation, response, and forensics, with a federal baseline of six months searchable and one year retrievable logs. Agencies must submit Agency Logging Plans within 90 days and work toward Advanced maturity within 320 days; the guidance also treats AI outputs as derived data requiring human review and preserved metadata.

CISA and NIST Issue Guidance to Protect Cloud Identity Tokens

CISA and NIST published Interagency Report 8587 with voluntary guidance to harden cloud identity tokens against theft, forgery, and lateral movement.

CISA and NIST released NIST Interagency Report 8587 on September 15 with final voluntary guidance for federal agencies, cloud providers, and their customers on protecting SSO, federation, and API tokens. Requirements include one-hour maximum token lifetimes, 90-day signing key rotation for high-impact systems, hardware-backed key storage, explicit audience fields, and keeping tokens out of logs. The guidance was motivated by the 2020 ADFS compromise where forged SAML assertions bypassed MFA, and an incident where a leaked consumer signing key enabled token forgery and theft of 60,000+ emails from one agency. Nearly 250 public comments shaped the text, with input from Google, Microsoft, Okta, AWS, Oracle, IBM, HashiCorp, Wiz, and the OpenID Foundation via the Joint Cyber Defense Collaborative.

U.S. CISA adds Cisco Secure Email Gateway flaw to its Known Exploited Vulnerabilities catalog

CISA added actively exploited Cisco Secure Email Gateway zero-day CVE-2026-76461 (CVSS 9.8) to KEV; federal agencies must patch by September 17, 2026.

CISA added CVE-2026-76461 (CVSS 9.8), a critical zero-day in Cisco AsyncOS for Cisco Secure Email Gateway, to its Known Exploited Vulnerabilities catalog. The flaw stems from insufficient validation in email parsing, letting an unauthenticated remote attacker send a crafted email with malicious SQL statements to achieve arbitrary command execution with root privileges. Cisco confirmed active exploitation in the wild, notes no workarounds exist, and recommends checking mail_logs for suspicious SQL statements like 'COPY.*TO PROGRAM' on every cluster device. Under BOD 22-01, FCEB agencies must remediate by September 17, 2026.
