Android 17 Adds OS-Wide ECH to Hide Website Visits From Network Providers

Google announced Android 17 will enforce OS-wide Encrypted Client Hello with ECH GREASE, plus Certificate Transparency by default and carrier 2G disablement.

Google announced Android 17 network security protections headlined by OS-wide support for Encrypted Client Hello (ECH), with ECH GREASE enabled by default so connections to non-ECH servers look identical. Google's Jigsaw noted OkHttp has integrated ECH, letting third-party Android apps adopt the standard. The release also enforces Local Network Protection permission prompts, enables Certificate Transparency by default, and lets carriers turn off 2G by default to prevent downgrade attacks, rogue base stations, and SMS blasters. ECH was previously added to Chrome 117 and Firefox 118 at the browser level only.

CISA promotes a fresh way to deter cyberattackers: Lie to them

CISA issued first-time guidance advising critical infrastructure operators to deploy honeypots, honeytokens, and decoys to detect and distract intruders.

CISA published 'Using Cyber Decoys to Strengthen Detection and Response,' a 22-page guide marking the agency's first guidance on decoys such as honeypots and honeytokens. Acting executive director Chris Butera described decoys as a low-cost, high-fidelity way to detect adversaries already inside networks, complementing zero-trust and assume-compromise approaches. The guidance covers decoy principles, definitions, deployment scenarios, and is aimed especially at resource-constrained critical infrastructure sectors.

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.

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.

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.
