📝 Executive Summary — 10-Second Read

• 🔴 Check Point CVE-2026-16232 is an actively exploited security-management-plane vulnerability. Under specific exposed configurations, an unauthenticated attacker can obtain an application login token and access SmartConsole with full administrative privileges. Check Point says a handful of customers were affected, and CISA has added the flaw to its Known Exploited Vulnerabilities catalogue.

• 🔴 Russian state-supported LAUNDRY BEAR is exploiting Zimbra CVE-2025-66376 for email espionage. A victim only needs to view a malicious message in the vulnerable Classic webmail interface. The attack then attempts to steal 90 days of email, credentials, address-book data and authentication artefacts.

• 🟠 Chaos ransomware operators are using msaRAT to turn Chrome or Edge into the malware’s external C2 client. The RAT controls a headless browser through Chrome DevTools Protocol, then moves traffic through WebRTC, Cloudflare Workers and Twilio TURN infrastructure.

• 🟠 A fake Claude Desktop malvertising campaign reached thousands of users and generated malicious activity across at least 29 organisations. Victims were redirected from Bing advertisements to a malicious user-generated page on the legitimate Claude.ai domain before downloading a DLL-sideloading loader associated with SectopRAT or a closely related fork.

🔍 Major Incidents: Technical Analysis

1. CVE-2026-16232: Check Point SmartConsole Authentication Bypass

Check Point CVSS: 9.3 — Critical
CISA-ADP CVSS v3.1: 9.1 — Critical
Analyst operational priority: 🔴 Critical
Direct impact: Full administrative control of Check Point security management
Exploitation status: Confirmed by Check Point; listed in CISA KEV
Primary exposure condition: Management server reachable from the Internet without sufficiently restrictive Trusted Client controls

Incident Overview

Check Point disclosed active exploitation of CVE-2026-16232, an authentication-bypass vulnerability affecting the SmartConsole login process for Security Management and Multi-Domain Management environments.

An unauthenticated remote attacker can obtain an application login token and use it to authenticate through SmartConsole with full administrative privileges.

Check Point says the observed exploitation affected a handful of customers using a specific high-risk configuration:

• The management service was directly exposed to the Internet.

• Trusted Client restrictions did not sufficiently limit remote access.

Smart-1 Cloud customers were already protected.

Affected release families include:

• R81.10

• R81.20

• R82

• R82.10

• Older supported and unsupported releases identified by Check Point

Check Point released a Jumbo Hotfix on July 22, 2026. CISA’s KEV catalogue gives United States federal civilian agencies a July 25 remediation deadline.

Technical Deep-Dive

SmartConsole is not simply an endpoint-management application.

It is a control interface for:

• Security policy

• Network and service objects

• Administrator permissions

• Threat-prevention settings

• Logging configuration

• Policy deployment across managed gateways

The vulnerable trust flow can be represented at a high level as:

Unauthenticated remote request
            ↓
Application login-token acquisition
            ↓
SmartConsole accepts the token
            ↓
Full administrative management session
            ↓
Security-policy and configuration modification

The core security failure is that an attacker can obtain an application token that the management service accepts as sufficient proof of identity.

Once authenticated, the attacker may gain the same control normally available to an authorised security administrator, including the ability to:

• Modify firewall rules

• Alter network and service objects

• Change security configurations

• Create or modify administrators

• Push policies to managed gateways

• Potentially weaken logging, inspection or threat-prevention controls

This makes CVE-2026-16232 more consequential than a vulnerability affecting a single firewall process.

A compromised management server can become a mechanism for altering the behaviour of multiple downstream security gateways.

Check Point states that remote exploitation requires:

• Network access to the management-server IP

• A configuration that does not sufficiently restrict Trusted Clients or GUI Clients

Why This Matters

Security-management platforms are high-value control planes.

If an attacker compromises an ordinary server, defenders may isolate that host.

If an attacker compromises the platform that defines security policy, the attacker may be able to make malicious activity appear authorised by changing the controls themselves.

Potential outcomes include:

Management compromise
        ↓
Firewall-rule modification
        ↓
New external or lateral access paths
        ↓
Reduced inspection or logging
        ↓
Persistent access across managed networks

Mitigation and Threat Hunting

1. Install the latest Check Point Jumbo Hotfix immediately.

2. Restrict SmartConsole and management-server access to:

   • Dedicated management networks

   • Approved jump hosts

   • VPN or identity-aware administrative access

   • Explicit trusted IP addresses and subnets

3. Review the Trusted Clients／GUI Clients configuration and remove broad, legacy or unrestricted entries.

4. Confirm that implied control-connection rules remain enabled and that management access is protected by firewall policy.

5. Hunt for:

   • Unknown application-login tokens

   • Administrative sessions from unfamiliar IP addresses

   • New administrator accounts

   • Changes to Trusted Clients

   • Security-policy or object changes outside approved windows

   • Unexpected policy installations to gateways

   • Logging, inspection or threat-prevention settings being disabled

   • New management API activity

   • Configuration exports from unfamiliar accounts

6. Compare the current gateway policy with a known-good configuration backup.

7. Review changes made before the hotfix was installed, not only events recorded after remediation.

8. If exploitation is suspected:

   • Rotate administrator passwords

   • Revoke API and application tokens

   • Terminate active management sessions

   • Review every managed gateway

   • Restore unauthorised policy changes

   • Investigate whether new access paths were created before patching

9. Treat successful exploitation as a security-control-plane compromise, not merely as an exposed administrative service.

2. CVE-2025-66376: LAUNDRY BEAR Turns a Viewed Zimbra Email into an Espionage Operation

MITRE CNA CVSS v3.1: 7.2 — High
NVD CVSS v3.1: 6.1 — Medium
Analyst operational priority: 🔴 Critical for exposed, unpatched Zimbra environments
Threat actor: LAUNDRY BEAR, also tracked as Void Blizzard, CL-STA-1114 and TA488
Direct impact: Authenticated-session abuse, email theft and credential access
Persistence risk: Application-password creation, protocol enablement and continued mailbox access
Exploitation status: Confirmed zero-day exploitation from at least July 2025; listed in CISA KEV
Fixed versions: Zimbra 10.0.18 and 10.1.13

Incident Overview

A multinational government advisory attributes an ongoing email-espionage campaign to the Russian state-supported group LAUNDRY BEAR.

The operation targets organisations using Zimbra Collaboration Suite.

The group began exploiting CVE-2025-66376 in July 2025, months before the vulnerability was publicly disclosed and patched in November 2025.

Unlike conventional phishing, the victim does not need to:

• Download a file

• Enable macros

• Click a link

• Approve an application

The malicious JavaScript executes when an authenticated user views the crafted message in a vulnerable version of Zimbra’s Classic webmail interface.

The campaign has targeted organisations associated with:

• Government

• Defence

• Energy

• Law enforcement

• Education

• Media

• Technology

• Non-governmental organisations

The advisory assesses that LAUNDRY BEAR’s objective is covert intelligence collection rather than financial extortion.

CVSS Discrepancy

MITRE’s CNA assessment gives the vulnerability a CVSS v3.1 score of 7.2, while NVD assigns 6.1.

A major difference is the treatment of user interaction:

• MITRE CNA: UI:N

• NVD: UI:R

Operationally, the victim must view the malicious message in the vulnerable Classic interface.

However, the required action is routine mailbox use rather than an exceptional interaction such as opening an attachment or approving a warning.

For exposed, unpatched systems used by high-value organisations, the demonstrated zero-day exploitation and session-level impact justify a Critical operational priority despite the lower base scores.

Technical Deep-Dive

CVE-2025-66376 is a stored cross-site scripting vulnerability involving insufficient sanitisation of CSS @import directives in HTML email.

The attacker sends a crafted message containing malicious HTML, CSS and an SVG element.

When the user opens the email, the content is rendered inside the trusted Zimbra webmail origin.

At a high level:

Malicious HTML email
        ↓
CSS @import processing bypasses sanitisation
        ↓
SVG onload handler executes
        ↓
Base64 payload is decoded
        ↓
XOR-encrypted JavaScript is decrypted
        ↓
Script executes with the user’s Zimbra session

Because the payload runs in the authenticated webmail context, it can invoke Zimbra APIs and access information available to the victim’s session.

Ulej Collection Workflow

The government advisory describes a custom capability named Ulej, which attempts to collect and exfiltrate data in 12 asynchronous stages.

Targeted information includes:

• The previous 90 days of non-junk email

• The victim’s email address

• Mailbox credentials

• Global Address List data

• 2FA scratch codes

• OAuth consumer information

• Device-status information

• Saved credentials exposed through browser or password-manager autocomplete

• Existing application-specific passwords

The malware also attempts to:

• Enable mail-access protocols

• Create a new application passcode named ZimbraWeb

• Preserve access after the original browser session ends

Exfiltration Infrastructure

Collected data is sent to an attacker-controlled framework named Flowerbed.

The government advisory describes Flowerbed as a Docker-based Python project containing four primary components:

• Catcher: Receives exfiltrated data over DNS and HTTP

• Certbot: Automates Let’s Encrypt certificate generation

• Nginx: Provides an HTTPS reverse proxy and filters connections by SNI

• Gardener: Performs service health checks

The framework can use both HTTPS and DNS to receive stolen information, making the operation more resilient when one exfiltration method is blocked.

The advisory also notes indications that AI assisted the development of parts of the relatively simple Flowerbed codebase.

Why This Matters

A vulnerability with a Medium or High CVSS score can still create severe operational risk when it executes inside an authenticated email session.

The victim does not need to make an obvious security mistake:

User opens email
      ↓
Malicious code inherits authenticated mailbox context
      ↓
Email and authentication data are collected
      ↓
Persistent mailbox access may be established

This reduces the effectiveness of traditional awareness messaging focused solely on:

• Do not click links

• Do not open attachments

• Do not enable macros

Mitigation and Threat Hunting

1. Upgrade to:

   • Zimbra 10.0.18 or later

   • Zimbra 10.1.13 or later

2. If immediate patching is impossible:

   • Stop using the vulnerable Classic webmail interface

   • Direct users to a supported desktop or mobile mail client

   • Restrict Internet access to the webmail service where possible

3. Search for malicious emails containing:

   • Repeated CSS @import directives

   • Suspicious SVG elements

   • Base64 content in onload attributes

   • Obfuscated or XOR-decrypted JavaScript

   • References to known campaign infrastructure

4. Review Zimbra activity for:

   • Bulk email access covering approximately 90 days

   • Repeated SearchGalRequest operations

   • CreateAppSpecificPasswordRequest

   • Application passcodes named ZimbraWeb

   • GetScratchCodesRequest

   • Mail protocols being enabled unexpectedly

   • New forwarding rules

   • New mailbox delegates

   • OAuth consumer or delegated-access changes

5. For suspected victims:

   • Quarantine related malicious messages

   • Revoke active sessions

   • Reset passwords

   • Re-enrol MFA

   • Regenerate 2FA scratch codes

   • Delete unauthorised application passwords

   • Review forwarding, filters, OAuth access and delegated permissions

   • Determine the historical period of potential email exfiltration

6. Search for related activity across other mailboxes that received the same message or accessed the same infrastructure.

3. msaRAT: Chaos Ransomware Operators Use Chrome and Edge as Covert C2 Proxies

Analyst operational priority: 🟠 High
Threat association: Chaos ransomware operators
Category: Rust remote-access trojan／living off trusted applications
Primary evasion method: External C2 traffic originates from a legitimate browser process

Incident Overview

Cisco Talos analysed a new Rust-based remote-access trojan named msaRAT associated with Chaos ransomware operations.

The malware avoids making direct external C2 connections from its own process.

Instead, it:

1. Launches Chrome or Edge in headless mode.

2. Controls the browser through Chrome DevTools Protocol.

3. Instructs the browser to create the external communications channel.

4. Passes C2 data between the browser and malware over localhost.

From a network perspective, the traffic appears to originate from a trusted browser connecting to recognised cloud and communications infrastructure.

Technical Deep-Dive

After locating Chrome or Edge through environment variables or registry paths, msaRAT starts the browser using CreateProcessW.

The browser is launched with command-line flags enabling:

• Headless mode

• A remote-debugging port

• An attacker-controlled browser profile

• Chrome DevTools Protocol access

msaRAT then queries:

/json/list/

The browser returns details about debug targets, including a WebSocket endpoint.

The RAT connects to this endpoint and issues CDP commands including:

• Target.createTarget

• Page.enable

• Runtime.enable

• Page.setBypassCSP

• Runtime.addBinding

• Runtime.evaluate

These commands:

• Create a new browser tab

• Weaken browser-side content restrictions

• Register communication callbacks

• Inject attacker-controlled JavaScript

WebRTC C2 Construction

The injected JavaScript creates a WebRTC DataChannel.

The communication sequence is:

msaRAT process
      ↓ localhost WebSocket
Headless Chrome or Edge
      ↓
Cloudflare Worker for signalling
      ↓
WebRTC negotiation
      ↓
Google STUN / Twilio TURN
      ↓
Remote operator

The browser contacts a Cloudflare Worker to retrieve STUN and TURN configuration.

Talos observed:

• stun2.l.google.com for STUN

• global.turn.twilio.com as the TURN relay

The attacker can force the channel through Twilio’s TURN service rather than relying on a direct peer-to-peer path.

The browser also disguises the request’s Origin and Referer as Microsoft-related traffic.

The RAT registers JavaScript callbacks such as:

• msaOpen

• msaClose

• msaError

• msaMessage

• dataAck

Data received by the browser is passed to the malware through these CDP bindings.

The important telemetry gap is:

msaRAT → only communicates with localhost
Browser → performs the external C2 traffic

A security product that attributes network activity only to the process creating the external socket may therefore see Chrome or Edge—not the RAT—as the communicating process.

Mitigation and Threat Hunting

1. Alert when Chrome or Edge is launched by:

   • MSI installers

   • Windows services

   • Scheduled tasks

   • Script interpreters

   • Unusual non-interactive parent processes

   • Processes running without a logged-in user

2. Hunt for browser command-line arguments including:

   • --headless=new

   • --remote-debugging-port

   • Non-standard --user-data-dir

   • Unexpected proxy or certificate flags

3. Detect localhost WebSocket connections to Chrome DevTools Protocol endpoints.

4. Monitor browser processes for:

   • WebRTC DataChannels without corresponding user activity

   • Unexpected TURN traffic

   • Connections to Twilio TURN infrastructure from servers

   • Cloudflare Worker traffic from newly launched headless browsers

   • Long-lived browser processes with no visible window

5. Correlate external browser traffic with:

   • Process ancestry

   • Interactive-user sessions

   • Browser-window visibility

   • Remote-debugging activity

   • Localhost WebSocket connections

6. Investigate unexpected MSI packages, particularly installers masquerading as Windows updates.

7. Do not automatically classify Chrome or Edge traffic as benign solely because the executable is signed and widely used.

8. Apply application-control policies to prevent unapproved software from launching browser processes with remote-debugging capabilities.

4. FakeAgent: Fake Claude Desktop Ads Deliver a SectopRAT-Associated Loader

Analyst operational priority: 🟠 High
Category: Malvertising／trusted-platform abuse／DLL sideloading
Observed scope: Related malicious activity across at least 29 organisations
Initial lure: Bing advertisements for “Claude Desktop App”
Final-payload assessment: SectopRAT or a closely related fork

Incident Overview

Huntress identified a malvertising campaign targeting people searching Bing for the Claude desktop application.

Sponsored results led users to a malicious public Claude Artifact hosted on the legitimate Claude.ai domain.

The page imitated an official Claude Desktop download and redirected users to an attacker-controlled domain serving ClaudeDesktop.exe.

Before Anthropic removed the malicious Artifact, Huntress recorded approximately 7,100 page views.

Between July 21 and July 22, Huntress observed related malicious activity across at least 29 organisations.

This does not necessarily mean every organisation experienced the same degree of compromise. However, the observation confirms that the campaign progressed beyond advertising impressions and download-page visits.

Technical Deep-Dive

The attack chain combines:

• Trusted-domain abuse

• Sponsored search advertisements

• Signed binaries

• DLL sideloading

• Anti-analysis controls

• Blockchain-based infrastructure discovery

Bing sponsored result
        ↓
Malicious Artifact on legitimate Claude.ai
        ↓
External attacker-controlled download site
        ↓
Fake ClaudeDesktop.exe
        ↓
Signed JetBrains CEF component
        ↓
Malicious libcef.dll sideloaded
        ↓
Blockchain-based C2 discovery
        ↓
SectopRAT-associated payload

The file named ClaudeDesktop.exe is actually a legitimate JetBrains Chromium Embedded Framework helper component.

The attacker places a malicious libcef.dll beside the signed executable.

Because the legitimate program searches its local directory for the DLL, it loads the attacker-controlled library.

This gives the malicious code execution within the context of a signed and otherwise trusted application.

Blockchain-Based C2 Discovery

The loader is protected with VMProtect and references an Ethereum-compatible smart contract.

Rather than storing cryptocurrency, the contract provides encrypted C2 configuration.

The attacker can update the contract transaction data to rotate infrastructure without modifying the original malware.

This technique is commonly described as EtherHiding.

Persistence and Anti-Analysis

The campaign also writes DockerDesktop.exe, which is functionally identical to the initial fake Claude executable, and creates a scheduled task to reinfect the device.

Huntress identified another persistence path under:

%APPDATA%\Roaming\Microsoft\EdgeUpdate\Install\

A signed IBM SPSS executable named sslconf.exe sideloads a malicious tempdir.dll.

The second-stage DLL uses a GPU anti-VM check, examining graphics hardware before deciding whether to run.

This reduces the likelihood that the payload will execute inside automated malware-analysis environments.

Final-Payload Assessment

Huntress assessed the final payload as SectopRAT or a closely related fork, based on:

• Data-theft functionality

• Hidden VNC behaviour

• Strings and implementation similarities

• C2 information recovered through blockchain transactions

Observed strings and behaviour indicated capabilities including:

• Password and browser-cookie theft

• Payment-card and personal-data theft

• Local-file collection

• VPN and messaging credential theft

• Hidden VNC for interactive remote control

These capabilities should be treated as malware functionality, not as proof that every capability was exercised in every affected environment.

Mitigation and Threat Hunting

1. Install AI desktop applications only through:

   • Verified vendor pages

   • Managed enterprise software distribution

   • Approved application catalogues

2. Do not treat the following as sufficient proof that a download is safe:

   • Search ranking

   • Sponsored status

   • A legitimate hosting domain

   • A signed executable

   • A familiar product name

3. Hunt for:

   • ClaudeDesktop.exe outside approved installation paths

   • DockerDesktop.exe associated with unexpected scheduled tasks

   • JetBrains CEF binaries loading an untrusted libcef.dll

   • sslconf.exe loading tempdir.dll

   • %APPDATA%\Roaming\Microsoft\EdgeUpdate\Install\

   • Unexpected Defender exclusions

   • Ethereum or BSC contract queries from desktop installers

4. Compare loaded DLL hashes against the expected software package.

5. Restrict DLL execution from user-writable directories.

6. Apply application-control policies to unsigned or unknown libraries loaded by signed applications.

7. Where execution is confirmed, rotate:

   • Browser sessions and cookies

   • Saved browser passwords

   • VPN credentials

   • Developer tokens

   • Messaging accounts

   • Cloud and SaaS sessions

8. Review browser, endpoint and identity-provider telemetry for post-compromise account access.

9. Investigate every affected device for secondary payloads rather than treating removal of the fake installer as complete remediation.

🔐 Data-Breach Watch

Origin Energy Confirms Customer-Data Exposure

Analyst-assessed impact: 🟠 Medium to High for confirmed affected customers
Confirmed status: Unauthorised access to and disclosure of some customer data
Claimed scale: Approximately two million customer records; not confirmed by Origin

Incident Overview

Origin Energy confirmed that an unauthorised party accessed and disclosed customer information.

Potentially affected data includes:

• Names

• Addresses

• Dates of birth

• Telephone numbers

• Account information

• Partial credit-card numbers

• Partial bank-account details

Origin says the exposed financial information was incomplete and could not independently be used to conduct transactions.

The company is:

• Notifying confirmed affected customers

• Working with cybersecurity specialists

• Coordinating with the Australian Federal Police

• Engaging with the Australian Cyber Security Centre

An individual claiming responsibility told media outlets that data relating to approximately two million customers had been accessed.

Origin has not confirmed that figure.

It should therefore be treated as an attacker claim rather than an established breach count.

Defensive Takeaway

Partial identity and financial data can still enable convincing:

• Phishing

• Vishing

• Account impersonation

• Refund scams

• Payment-change fraud

• Credential-recovery attacks

Customers should be cautious when a caller or message demonstrates knowledge of:

• Their home address

• Date of birth

• Energy account

• Billing history

• Payment-card suffix

• Bank-account suffix

Knowledge of those details does not prove that the sender represents Origin, a bank or a government authority.

Mitigation

Organisations handling similar customer data should:

1. Require additional verification before:

   • Changing payment instructions

   • Resetting credentials

   • Updating contact information

   • Enrolling new authentication methods

   • Disclosing account details

2. Monitor for:

   • Repeated customer-account lookups

   • Bulk data exports

   • Help-desk impersonation

   • Password-reset attempts using exposed identity data

   • Fraudulent refund or rebate campaigns

3. Brief customer-service teams on the specific data types that may have been exposed.

4. Avoid using static personal information such as date of birth or address as sufficient identity verification.

---

📌 Final Assessment

Today’s incidents share a single defensive lesson:

Trusted systems are increasingly being used to make malicious actions appear legitimate.

• A valid-looking SmartConsole token can become full control of the security-management plane.

• A viewed email can inherit an authenticated Zimbra session.

• Chrome or Edge can carry a ransomware operator’s C2 traffic.

• A legitimate Claude.ai page and signed software components can deliver a RAT.

• Real customer information can make fraudulent calls and messages appear authentic.

The operational response must therefore go beyond blocking unknown binaries and domains.

Defenders must verify:

• Who created or obtained a trusted token

• Whether an authenticated session is behaving normally

• Why a browser is communicating with external infrastructure

• Which libraries a signed application has loaded

• Whether personal information is being used to bypass account-verification controls

• Whether a security-management platform has changed its own protections

The defensive priority is clear:

Verify how trusted identities, tokens, applications and control planes are behaving—and investigate whenever their behaviour no longer matches their intended purpose.
