Opinion piece argues attackers prioritize repeatable playbooks like ClickFix (47% of Microsoft-notified attacks) and living-off-the-land over novel techniques.
The column analyzes why commodity techniques scale: Microsoft observed ClickFix as the top initial access method at 47% of its notifications last year, while Bitdefender found 84% of 700,000 analyzed high-severity incidents involved binaries already present on machines. Verizon's DBIR shows vulnerability exploitation rising to 31% of initial access vectors, up from 20%, and ransomware leak-site rankings show Qilin (roughly 1,600 claimed victims) and The Gentlemen (121 claimed victims in June) competing on throughput. The author argues attackers behave like a generics business, standardizing repeatable procedures rather than investing in novel tradecraft.
Op-ed argues the 200-company Collective Cyber Defense letter's three endorsed metrics should become standard vendor procurement questions.
More than 200 companies including Microsoft, Google, AWS, CrowdStrike, Anthropic and Okta signed an August 27 open letter calling for faster cyber defenses against AI-enabled attacks. The letter endorses three measurable metrics: coverage, containment speed, and verified remediation. The author turns those into five concrete procurement questions buyers should pose at vendor renewals, while noting the letter contains no deadlines, dollar figures or measurable targets.
77 malicious 'evil twin' Open VSX extensions impersonated developer tools and exfiltrated hostnames and detailed workspace reconnaissance to mangorbit.com.
Manifold Security found 77 extensions uploaded to the Open VSX marketplace between July 26 and August 1, 2026 that impersonate real Microsoft VS Code Marketplace tools, with all 77 sending data to mangorbit.com. 58 lightweight variants exfiltrate the hostname, while 19 recon variants collect editor details, OS username, Git remote hosts, CI environment variables (GitHub, GitLab, Azure DevOps, Buildkite, CircleCI, Codespaces, Gitpod), and installed extension IDs. The recon variant retries for up to seven days and can fall back to a DNS TXT record for exfiltration if the primary domain is blocked. The extensions were removed from Open VSX by August 3, 2026; the disclosure follows a separate npm supply chain campaign, ChainDrop, which compromised 450 packages with a Shai-Hulud worm variant.

The report stresses that attacker activity frequently resembled legitimate business behavior.
Unit 42 details 'Spring Ring', a vishing campaign using fake IT support on Microsoft Teams to reach 150+ employees at 10+ companies.
Palo Alto Networks Unit 42 documented 'Spring Ring', a voice-phishing campaign that ran January to April 2026, using 26 attacker identities and fake Microsoft 365 tenants such as 'ITProtectionDepartment' to impersonate internal IT support on Microsoft Teams. One path used Quick Assist or downloaded remote-support tools to run an obfuscated PowerShell script that disabled malware scanning before contacting C2; the other delivered a cloud-hosted file triggering browser hijacking, SMB internal network scanning, and a PetitPotam NTLM relay attempt against domain controllers to gain domain-level privileges. Both intrusion attempts were blocked before attackers reached their objectives. Collaboration-platform phishing alerts rose to 42% of Unit 42's telemetry in early 2026, up from 30%.
White House launches Watershed 250, a six-month Texas pilot using volunteer vendor cyber and AI tools to harden water utility defenses.
The Office of the National Cyber Director and Texas Cyber Command will oversee the six-month Project Watershed 250 pilot to improve water sector cybersecurity through industry-donated red teaming, system hardening and AI tooling. Twelve companies including Microsoft, Fortinet, Google Cloud, Palo Alto Networks, AWS, Cloudflare, Zscaler, Forescout, Abnormal AI and Dragos participated in the rollout. Officials cited recent attacks including an Iranian-backed campaign against 30 water systems in 12 states and a 2024 incident in Muleshoe, Texas. Some water-security professionals criticized the program as lacking dedicated funding.
A write-up demonstrates privilege escalation from an IIS AppPool identity to NT AUTHORITY/SYSTEM via the AD CS RPC endpoint.
A technical write-up details a Windows privilege escalation path that moves an IIS application pool identity to NT AUTHORITY/SYSTEM by abusing the Active Directory Certificate Services RPC endpoint. The technique chains the restricted IIS AppPool service context with AD CS access to reach SYSTEM on the host. The post is relevant for defenders mapping privilege escalation paths on Windows web servers.
Unit 42 details the Spring Ring voice phishing campaign abusing Microsoft Teams to deploy malware and target enterprise domain controllers.
Palo Alto Networks Unit 42 analyzed the Spring Ring campaign, which abuses Microsoft Teams and voice phishing (vishing) to compromise enterprise users.

The report documents the campaign's tactics and provides detection guidance for defenders.
Microsoft details TerminalFix, a ClickFix variant using fake Cloudflare CAPTCHAs to make users run PowerShell payloads with reverse-tunnel implants.
Microsoft disclosed TerminalFix campaigns that direct users to run commands in Windows Terminal or PowerShell instead of the Run dialog, increasing the chance multi-line scripts execute. Compromised websites serve fake Cloudflare CAPTCHA verifications; the resulting PowerShell command downloads a ZIP with legitimate LockScreenContentServer.exe and rogue dui70.dll for DLL sideloading, retrieves payloads hidden in PNG images from attacker domains, persists via Registry Run keys and scheduled tasks, and performs domain trust and Active Directory reconnaissance. A Python-based reverse-tunnel implant (client.py) tunnels arbitrary TCP traffic over an encrypted WebSocket to gitnow[.]dev:443, giving attackers network-level proxy access that could enable privilege escalation, security-tool tampering, data theft or ransomware. Microsoft recommends AppLocker restrictions, PowerShell script block logging and ClickFix awareness training.
Researchers found WebKit features bypass proxies and iCloud Private Relay, leaking users' real IP addresses; Apple patched in iOS 26.6.1 and macOS 26.6.2.
Researchers Talal Haj Bakry and Tommy Mysk found that three WebKit features — DNS prefetching, WebAuthn Related Origin Requests, and WebTransport — bypass configured proxies and send traffic directly from the device. This leaks the user's real IP address in Safari and all WebKit-based iOS browsers and undermines iCloud Private Relay's dual-hop privacy design. Any website can trigger the leak via WebAuthn without user interaction or passkey use; a proof-of-concept site, leaks.psylo.app, demonstrates the issue. Apple investigated and patched the leaks in iOS 26.6.1 and macOS 26.6.2.

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.
FBI and DOJ seized QTFY infrastructure, disrupting a Chinese state-sponsored group that compromised federal agencies and critical infrastructure since 2018.
Authorities seized three domains powering QScan and QTRouter, the hacking suite of QTFY, a Chinese government-funded group operating through front company Nanjing Xinjiuwei Network Technology. Targets include the Departments of Energy, Justice, and Health and Human Services, the Federal Reserve, NASA, NIH, financial institutions, defense contractors, utilities, telecoms, and hospitals; the group exploited zero-days in Ivanti, Pulse Secure, Fortinet, Citrix, and others, intruding three DOE national labs in September 2024. QScan carried over 200 proof-of-concept exploits and processed more than two million scanning tasks in a single day in 2024.
FBI seizes China-linked QScan and QTRouter hacking platforms used by QTFY to obfuscate intrusions against US federal agencies.
The DOJ and FBI seized domains hard-coded into QScan and QTRouter, two platforms operated by China-based Nanjing Xinjiuwei Network Technology Company on behalf of state-sponsored group QTFY. QScan automatically infected thousands of IoT devices which were added to QTRouter, an obfuscation network routing malicious traffic through compromised and proxy devices outside China. Targets included NASA, the Federal Reserve, Departments of Energy, Justice, and HHS, NIH, and the US Senate, exploiting flaws in Fortinet SSL-VPN, Citrix ADC, Microsoft Exchange, F5 BIG-IP, Log4j, and others.

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.
New NovaCookies adversary-in-the-middle phishing kit lets low-skill actors steal Microsoft 365 session cookies for $320 per month.
Dark Reading reports on NovaCookies, an adversary-in-the-middle (AitM) phishing service sold for roughly $320 per month. The kit lowers the barrier to entry for attackers to run credential-harvesting attacks against Microsoft 365. It goes beyond credentials by stealing active session cookies, enabling account takeover without triggering MFA.
Gen Digital details WordlistLoader delivering Amatera Stealer via ClickFix and EtherHiding, while SynkLoader phishes Windows credentials through Microsoft Teams.
Gen Digital identified WordlistLoader, an intermediate stage that reconstructs shellcode encoded as plain English words (or 16-byte UUID chunks) and loads Amatera Stealer 4.3.3-alpha1, delivered through ClearFake ClickFix prompts on compromised websites. The chain uses EtherHiding to fetch JavaScript from a blockchain smart contract, hidden cmd.exe via conhost, WebDAV-mounted shares with rundll32 execution, and ETW bypass via hardware breakpoints. The stealer adds hardened WoW64 syscalls, Heaven's Gate indirect-syscall trampolines and a redesigned application-bound encryption bypass. Separately, Expel observed SynkLoader distributed via Microsoft Teams phishing impersonating IT service desks, installing an MSI from Azure blob storage and serving a fake lock screen to capture credentials.
A hacker or insider leaked GTA VI gameplay footage before launch, triggering Take-Two DMCA subpoenas against Discord, Google, Microsoft and X.
The persona "CyberLeek" published stolen Grand Theft Auto VI gameplay footage and a manifesto, in what experts call a familiar data extortion playbook with monetization via watermarks, crypto wallets and a memecoin. Take-Two Interactive obtained DMCA subpoenas against Discord, Microsoft and X, and sent copyright notices to Google, treating the case like an insider threat investigation. GTA VI is projected to earn $3.3–5.2 billion in launch-week sales, raising financial and reputational stakes. Related leak websites went offline after the subpoenas.
The Linux Foundation adopts TRACE, an OPAQUE-contributed spec giving AI agents hardware-attested, cryptographically verifiable runtime and compliance evidence.
The Linux Foundation accepted the TRACE (Trust, Runtime Attestation and Compliance Evidence) specification contributed by OPAQUE, developed with AMD, Intel, Microsoft, and the Technology Innovation Institute. TRACE binds runtime environment, software, policies, data classifications, and tool usage into a portable, cryptographically verifiable artifact, composing existing standards such as RATS, EAT, SLSA, SCITT, SPIFFE, and EAR. It recorded nearly 135,000 PyPI downloads within 10 weeks of its June 2026 introduction, and its technical workstream will be hosted by the Coalition for Secure AI.
Recorded Future analysis says AI-driven vulnerability discovery and faster weaponization will grow the triage backlog while shrinking defenders' response windows.
Disclosed vulnerabilities rose from roughly 21,000 in 2021 to nearly 50,000 in 2025, while Recorded Future assessed only 446 as actively exploited in 2025. VulnCheck found nearly 29% of 2025 KEV entries were exploited on or before CVE publication. The authors argue AI-assisted discovery and automated exploit development will multiply credible reports, cut disclosure-to-exploit time toward minutes, and force re-evaluation of medium-severity flaws as exploit-chain components.
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.
SpecterOps released CDP-Enable-BOF, a Beacon Object File that enables Chrome DevTools Protocol in live Chrome or Edge processes on Windows for session hijacking.
SpecterOps released CDP-Enable-BOF, an x64 Beacon Object File that activates Chrome DevTools Protocol inside running chrome.exe or msedge.exe processes on Windows, exposing cookies, history, saved passwords, and authenticated sessions without administrator rights. It calls Chromium's StartRemoteDebuggingServer on the browser UI thread to stay reliable under CFG, TLS, and CET, and was tested on Chrome 147 and Edge 147. The technique builds on work by DeathFlamingo and Cedric Van Bockhaven; Google had hardened remote debugging in Chrome 136 after attackers used it to steal cookies post-App-Bound Encryption. Defenders can watch Sysmon Event IDs 8 and 10 for injection into browser processes.
Microsoft argues patch windows are shrinking and urges a new security control plane to protect systems between vulnerability discovery and remediation.
A Microsoft Security Blog post contends that the window between vulnerability discovery and patch deployment is collapsing, leaving exploitable gaps. It argues organizations need a security 'control plane' that provides protection in the gap between discovery and remediation. The piece is vendor thought leadership with no new incident, CVE, or product announcement details.
Mirage2FA phishing-as-a-service campaign hit ~4,500 organizations, mostly US, stealing Microsoft 365 passwords and session cookies to bypass 2FA.
ANY.RUN research links the Mirage2FA phishing-as-a-service toolkit to 4,532 unique organization email domains between 2024 and 2026, with the US accounting for 63.7% of victims. The kit uses adversary-in-the-middle login flows to harvest credentials and session cookies, bypassing MFA on Microsoft 365 accounts. Researchers recorded more than 9,000 potential compromise events and estimated 48% of targeted email addresses were potentially compromised. Hijacked sessions extend to SSO-connected services, enabling impersonation, fraud and further compromise.
August 2026 Patch Tuesday forecast urges risk-based triage as AI inflates CVE volume, flags actively exploited SharePoint RCE CVE-2026-50522 and LegacyHive Windows flaw.
July 2026 Patch Tuesday set records with over 600 CVEs, including 405 for Windows 11 and Server 2025, though only two were exploited zero-days and one was publicly disclosed. The author recommends prioritizing known-exploited and internet-facing vulnerabilities, matching patches to high-risk systems, and accelerating ring-based deployment toward Microsoft's suggested three-day turnaround. Notable items include actively exploited SharePoint RCE CVE-2026-50522 enabling machine key theft, the unassigned LegacyHive Windows User Profile Service flaw, and several end-of-servicing dates for Windows and Exchange.
Attackers spread fake 113GB GTA VI builds whose 50KB payload whitelists the entire C: drive in Windows Defender, alongside credential phishing and infostealer campaigns.
Researchers found that a 113GB file claiming to be a playable Grand Theft Auto VI build is 99.99% empty data hiding a tiny malicious payload that excludes the entire C:\ drive from Windows Defender and kills security software, preparing systems for follow-on attacks. Related lures include fake GTA 6 Windows installers using DLL side-loading, a fake 'GTA 6 Mobile' app redirecting to infostealer and ransomware infrastructure, and counterfeit Rockstar Social Club login pages harvesting credentials. The fakes ride genuine leak momentum from the leaker CyberLeek, and Kaspersky separately documented over 19 million attempted downloads of game-themed malware in a year, with GTA, Minecraft, and Call of Duty the most abused brands. No legitimate playable GTA VI build is circulating; the game launches November 19 on consoles.
Heap-Based Buffer Overflow in Windows ALPC Enables Local Privilege Escalation
CVE-2026-85880 is a heap-based buffer overflow in Windows Advanced Local Procedure Call (ALPC), the Windows mechanism for local inter-process communication. An authorized local attacker can trigger the overflow by submitting crafted input over ALPC, corrupting heap memory in the component that handles the request. Successful exploitation allows the attacker to execute code with elevated privileges, typically gaining SYSTEM-level control of the local host, which is especially valuable as a post-exploitation or sandbox-escape step. Affected products include Windows 10 (1607, 1809, 21H2, 22H2) and Windows Server 2012, 2016, 2019, and 2022, meaning most on-premises Windows estates are in scope. The flaw was fixed in Microsoft's record 974-CVE September 2026 Patch Tuesday and was added to CISA's KEV on 2026-09-08, confirming exploitation in the wild; press reports describe Windows zero-days being chained with a Chrome zero-day in 'BlueMoon' kit attacks, though the data does not explicitly confirm this CVE is the Windows flaw in that chain.

Local Privilege Escalation via Link Following in Windows Update Stack
CVE-2026-81963 is a link-following flaw (CWE-59, improper link resolution before file access) in the Microsoft Windows Update Stack, in which the component fails to correctly resolve file links before opening them. A local attacker with low privileges can plant or manipulate a link (symlink/junction) that the privileged update stack follows during operation, redirecting its file access to an attacker-controlled target. The result is local privilege escalation — CVSS 3.1 rates this 7.8 (high) with high confidentiality, integrity, and availability impact — allowing an authorized local user or malware already on the machine to gain elevated rights. Affected products are Windows 11 23H2, 24H2, 25H2, and 26H1 and Windows Server 2025; any unpatched system on those versions is exposed to any local account holder. The flaw was fixed in Microsoft's record September 2026 Patch Tuesday (974 CVEs), was added to CISA's KEV on 2026-09-08 as one of two Windows zero-days reported as exploited in the wild, and has no known public PoC or confirmed ransomware use.

Use-After-Free Local Privilege Escalation in Microsoft Windows WinSock AFD Driver
CVE-2026-68820 is a use-after-free (CWE-416) in the Windows Ancillary Function Driver for WinSock (afd.sys), the kernel component that handles Winsock socket operations. A local, authenticated attacker can trigger the memory corruption through crafted socket activity, and the high attack-complexity score (AV:L/AC:H/PR:L) indicates exploitation requires a specific, likely race-sensitive sequence of operations. Successful exploitation elevates privileges to SYSTEM, giving the attacker full control of the host, and public reporting describes deployment of a backdoor after privilege escalation. Virtually every Windows 10, Windows 11, and Windows Server (2012-2022) installation ships this driver, so the affected population is essentially the entire supported Windows installed base. The flaw is being exploited in the wild: CISA added it to the KEV on 2026-08-11, Microsoft fixed it in the August 2026 Patch Tuesday release, and reporting ties active exploitation to North Korea's Lazarus group, who paired the zero-day with fake job-offer lures.

Actively Exploited V8 Type Confusion in Google Chrome (CVE-2026-85046)
Google Chrome versions prior to 152.0.7977.82 contain a type confusion flaw (CWE-843) in the V8 JavaScript engine, which mishandles object types during engine operations (public proof-of-concept writeups indicate it is reachable through array sorting and WebAssembly-related code paths). A remote attacker triggers the flaw simply by getting a user to open a crafted HTML page, with no privileges or authentication required. Successful exploitation lets the attacker execute arbitrary code inside the browser's sandbox, and public reporting shows it being chained with Windows zero-days (the 'BlueMoon' exploit kit) by Chinese espionage groups for broader compromise. Any user of an unpatched Chrome or another build embedding the affected V8 engine is exposed. The vulnerability is a zero-day that was actively exploited in the wild before patching, was added to CISA's KEV on 2026-09-04, and has five public proof-of-concept references.

Local Elevation of Privilege in Microsoft Defender Malware Protection Engine
CVE-2026-69414, publicly dubbed 'ShieldBreak', is a high-severity (CVSS 3.1: 7.8) elevation-of-privilege flaw in the Microsoft Malware Protection Engine (MMPE) that powers Microsoft Defender, rooted in improper access control and improper privilege management (CWE-284/CWE-269). It is triggered locally: an attacker who already holds low privileges on the machine needs no user interaction (AV:L/AC:L/PR:L/UI:N) to trip the engine's flawed access checks, and successful exploitation yields high impact to confidentiality, integrity, and availability. News coverage reports public PoCs released under the 'ShieldBreak'/'ShieldCrash' names demonstrating SYSTEM-level access on Defender-protected Windows systems, including claims that the shipped patch can be bypassed and arbitrary files read as SYSTEM. Because MMPE ships as the scan engine inside Microsoft Defender, effectively every Defender-protected Windows 10/11 endpoint and server is potentially affected, though the source data specifies no affected engine version ranges. There is no confirmed in-the-wild exploitation (EPSS 0.6%, absent from CISA KEV), but given the public PoC claims, defenders should assume working exploit code exists.

Authentication Bypass in Microsoft SharePoint Server
Microsoft SharePoint Server is affected by a weak authentication vulnerability (CWE-1390) that allows an unauthorized attacker to bypass a security feature over a network. Per the CVSS vector, exploitation requires no privileges and no user interaction with low attack complexity, so any unauthenticated attacker with network access to a vulnerable server can trigger it remotely. Impact to confidentiality and integrity is rated high (CVSS 9.1, critical), meaning the bypass effectively grants the attacker access that authentication should have prevented, with no direct availability impact. All organizations running on-premises Microsoft SharePoint Server are potentially affected; the source data does not specify affected version ranges or fixed builds, so defenders should consult Microsoft's advisory for those details. The flaw is under active exploitation: a public proof-of-concept is available on GitHub, attackers began exploiting it after the PoC went public, and CISA added it to the Known Exploited Vulnerabilities catalog on 2026-08-18 (EPSS ~40%, 99th percentile; ransomware association unknown).
CVE-2026-69730 is a use-after-free memory corruption flaw (CWE-416) in the Windows DNS service that allows an unauthenticated, remote attacker to execute arbitrary code by sending crafted network traffic to the affected system. Because the flaw is network-exploitable with no privileges or user interaction required (CVSS 3.1 9.8), any system running the vulnerable DNS service is a direct target. Successful exploitation would give the attacker code execution in the context of the DNS service, which on Windows Server typically runs with high privileges such as SYSTEM, and could enable wormable spread between vulnerable hosts. Affected organizations are those running the Windows DNS Server role — a component deployed on virtually all Windows Server domain controllers and on dedicated Windows DNS servers, especially those exposed to untrusted networks. As of the September 2026 Patch Tuesday release, there is no known public proof-of-concept, the flaw is not listed in CISA's KEV, and it has not been confirmed exploited in the wild, though it was flagged among roughly 20 'wormable' bugs and described in press coverage as a successor to the 2020 SigRed Windows DNS RCE.

Unauthenticated RCE in Microsoft SharePoint Server
CVE-2026-63520 is an improper input validation flaw (CWE-20) in Microsoft Office SharePoint, affecting on-premises SharePoint Server deployments. A remote, unauthenticated attacker can trigger the flaw by sending improperly validated input to the SharePoint service over the network; the high attack complexity (AC:H) indicates exploitation depends on specific conditions, but no privileges or user interaction are required. Successful exploitation results in arbitrary code execution on the server, with high impact to confidentiality, integrity, and availability — effectively full compromise of the SharePoint host. Organizations running self-hosted SharePoint Server are in scope; SharePoint Online/Microsoft 365 is not listed in the affected products. The issue is patched as of Microsoft's Patch Tuesday (headlines mark it FIXED), with Rapid7 analysis and a researcher-disclosed exploit chain available, but there is no public PoC, no CISA KEV listing, and no confirmed in-the-wild exploitation; EPSS puts exploitation probability at 2.9% (86th percentile).

Double Free Enables Unauthenticated RCE in Microsoft Exchange Server
CVE-2026-55007 is a double-free memory corruption flaw (CWE-415) in Microsoft Exchange Server in which the same heap allocation is freed twice, corrupting memory. A remote, unauthenticated attacker can trigger the flaw over the network, though the high attack complexity (AC:H) means reliable exploitation likely depends on favorable heap/timing conditions, making it harder to weaponize than typical pre-auth RCEs. Successful exploitation yields arbitrary code execution with high impact on confidentiality, integrity, and availability (CVSS 3.1: 8.1). Any organization running on-premises Microsoft Exchange Server is in scope, with the greatest risk on servers reachable from untrusted networks. As of now there is no public proof-of-concept, the flaw is not in CISA's KEV catalog, and EPSS estimates only a 0.7% chance of exploitation within 30 days; it was disclosed amid Microsoft's record September 2026 Patch Tuesday (974 CVEs), which press coverage highlighted for notable Exchange flaws.
