Cyber security developments for Friday the 17th of July 2026 covering articles added to the BlueTeamSec community on infosec.pub. Today we have 10 articles to cover. All attribution is by the article authors. All article analysis is automated.

The U.S. Department of State's Rewards for Justice program is offering up to ten million dollars for information on Russian malicious cyber actors, specifically those behind Media Land and ML.Cloud. Following on from the indictments we covered yesterday, these Russia-based entities allegedly provide infrastructure that helps malicious actors obfuscate their activities and evade law enforcement.

Thomson Reuters reports that Denis Obrezko, the alleged FSB-linked cyber spy we heard about earlier this week, previously worked as a senior specialist at Kaspersky Lab between 2017 and 2019, following what prosecutors claim was a five-year stint with Russia's FSB. The overlap raises uncomfortable questions about the line between Russian cybersecurity firms and state intelligence operations.

S2W have analysed BirdCall malware attributed to North Korea's ScarCruft group. The backdoor masquerades as the legitimate Zangi messenger app for Android, uses dual Zoho WorkDrive accounts for command and control, and targets individuals in China's Yabian region for espionage. Worth flagging if you're tracking mobile threats in the region.

Qianxin Threat Intelligence Center have published analysis of a campaign by the Lazarus Group focusing on upgrades to their surveillance and monitoring programs. The source wasn't accessible for full details, but one for those tracking North Korean tooling evolution.

Hunt.io report that suspected Chinese operators conducted a sophisticated intrusion campaign in June targeting government and financial systems across Afghanistan, Thailand, Taiwan, and the United States. What's notable here is the use of large language models, specifically Claude Code and DeepSeek, integrated directly into their workflow to automate reconnaissance, exploit development, and phishing infrastructure creation.

Expel have identified CylindricalCanine, a subgroup of GoldenEyeDog, as responsible for the DigiCert supply chain incident back in April. The attackers used DLL sideloading, hijacked legitimate executables, and deployed the Golden Gh0st malware family with over nineteen hundred known malicious files. Initial access was achieved through a malicious file submitted via a support ticket, which is either impressively patient tradecraft or someone exploiting a very obvious gap in input validation.

Cyderes document a spear-phishing campaign by DoNot, also known as APT-C-35, targeting Bangladesh Air Force personnel. The India-aligned threat actor used weaponised RTF files with remote template injection, geofencing, and AES-encrypted command and control to deploy modular implants for intelligence gathering.

Elastic have analysed TELEPUZ, a modular Malware-as-a-Service threat active since late April. It spreads via ClickFix social engineering campaigns that trick users into executing PowerShell commands, then uses VIDAR infostealer as a secondary stager. The malware features financial data theft via WebInjector, browser manipulation using Chrome DevTools Protocol, and a rather elaborate command and control setup with multiple fallback methods including Telegram, Steam, DNS, and a Polygon blockchain smart contract.

Tailscale have disclosed an ACL bypass vulnerability in Tailscale SSH that allowed attackers with existing SSH access to gain root on Linux systems. The flaw involved usernames with leading hyphens being interpreted as command-line flags by a system utility, which is a wonderfully simple way to achieve privilege escalation. Fixed in version 1.98.9.

And finally, researchers have released cyber-decoy, an open-source containerised honeypot architecture that emulates SSH, RDP, and SMB services. It uses a two-tier architecture with kernel-level traffic monitoring and isolated Docker containers running service decoys. Worth a look if you're setting up deception infrastructure within authorised environments.

That concludes today's briefing.

Alleged Russian cyber spy in Boston case previously worked for Kaspersky, source says and documents show - Thomson Reuters

This précis outlines the case of Denis Obrezko, a central figure in a high-profile U.S. federal criminal case that has reignited scrutiny regarding the relationship between the Russian cybersecurity industry and state intelligence services.

### What Happened
Denis Obrezko, a 36-year-old computer expert, is currently in U.S. custody facing charges related to his role in a large-scale cyber espionage campaign 【1】. Following his arrest in Thailand last year and subsequent extradition, Obrezko appeared in a Boston federal court in June 2026, where he pleaded not guilty to computer crime charges 【1】【2】. Recent reports have revealed that Obrezko previously worked as a senior specialist at the Moscow-based antivirus firm Kaspersky Lab between 2017 and 2019, a period that followed his alleged five-year tenure with Russia’s domestic intelligence agency, the FSB 【3】.

### Who Is Affected
* **Targeted Organizations:** The campaign is linked to a group known as "Void Blizzard," which has targeted numerous U.S. companies, as well as entities in NATO member states and Ukraine 【1】【2】.
* **Kaspersky Lab:** The firm faces renewed reputational pressure and scrutiny regarding its historical hiring practices and potential susceptibility to influence by Russian intelligence agencies 【3】【4】.

### Security Implications
This case highlights the persistent risks associated with the "blurred lines" between the private cybersecurity sector and state-sponsored intelligence operations in Russia. The presence of individuals with intelligence backgrounds within private antivirus firms raises concerns about:
* The potential for insider threats or the deliberate introduction of vulnerabilities.
* The integrity of global supply chains when security software is developed by firms with deep links to state actors.

### Technical Details
* **Role of the Actor:** U.S. authorities allege Obrezko facilitated a campaign of cyberattacks by "Void Blizzard."
* **Attribution & Methods:** The FBI has tracked cryptocurrency transactions tied to the group's cyber activities, which served as a critical component in identifying and building the case against the suspects 【2】.

### What Defenders Should Know
Defenders and organizations should remain vigilant regarding the following:
* **Supply Chain Risk Management:** This incident underscores the importance of thorough vetting of third-party vendors, particularly those operating in jurisdictions where state-private sector cooperation is mandatory or common.
* **Threat Actor Tracking:** Defenders should continue to monitor the tactics, techniques, and procedures (TTPs) associated with "Void Blizzard," focusing on the infrastructure and financial trails (such as crypto-laundering) used to sustain their campaigns.
* **Institutional Awareness:** While this case involves a former employee, it serves as a reminder for security teams to maintain "zero trust" postures, assuming that even high-privileged software can be compromised or influenced by state-sponsored actors.
BirdCall: ScarCruft Malware Masquerading as Zangi Messenger - S2W

The S2W TALON team recently analyzed new variants of the "BirdCall" malware, a sophisticated backdoor associated with the North Korea-aligned threat actor ScarCruft (APT37) 【1】. Below is a detailed precis of the findings.

### What Happened
The ScarCruft group is actively distributing malicious Android applications by masquerading as the legitimate "Zangi" messenger. The attackers achieved this by repackaging the authentic Zangi application and modifying its entry point to execute malicious code alongside legitimate functionality 【1】.

### Who is Affected
Targeting efforts appear to be highly specific. Based on prior research by ESET, the malware has historically targeted individuals in China's Yabian region and other specific, yet-to-be-disclosed groups of interest to the threat actor 【1】.

### Security Implications
BirdCall functions as a high-level backdoor, granting the threat actor full control over compromised devices. Its primary objectives include:
* **Device Control:** Maintaining persistent remote access to infected mobile endpoints.
* **Espionage:** Unauthorized exfiltration of files and sensitive user information.
* **Information Gathering:** Continual collection of data from the device to support long-term intelligence gathering 【1】.

### Technical Details
* **C2 Architecture:** The malware uniquely leverages the legitimate Zoho WorkDrive service for its Command and Control (C2) operations. It uses two distinct cloud accounts, dubbed "cmdCloud" (for receiving commands) and "dataCloud" (for staging exfiltrated data) 【1】.
* **Communication & Exfiltration:** The malware supports eight remote command types. Collected data is processed through a custom packet format, utilizing AES-256-CBC encryption and zlib compression to evade detection 【1】.
* **Obfuscation:** To further hide its activity, the malware obfuscates filenames during uploads to Zoho WorkDrive using a Base-26 encoding scheme structured in an 11-base format 【1】.

### What Defenders Should Know
* **App Integrity:** The primary delivery mechanism relies on malicious repackaging. Defenders should emphasize the importance of downloading applications only from official, trusted sources and implementing mobile threat defense (MTD) solutions that can detect signature mismatches or unauthorized modifications in legitimate packages.
* **Traffic Monitoring:** Because the malware uses legitimate services (Zoho WorkDrive) for C2, standard blocking of malicious domains may be ineffective. Security teams should monitor for anomalous file creation, unusual traffic patterns to storage service APIs, and unauthorized attempts by messenger applications to access system files or sensitive data stores.
* **Behavioral Indicators:** Security analysts should focus on detecting the execution of modified packages and anomalous behavior by apps that should not require high-level permissions for background data exfiltration or device control 【1】.

Suspected Chinese Operators Use Claude Code and DeepSeek to Breach Government Systems Across Four Countries - Hunt.io

In June 2026, cybersecurity researchers discovered an active intrusion campaign linked to suspected Chinese threat actors that uniquely integrated Large Language Models (LLMs) directly into their operational workflow. The discovery stemmed from identifying an open directory on a server used by the attackers, which exposed a comprehensive operational toolkit including logs, victim data, and exploit scripts 【1】.

### **What Happened**
The attackers conducted a sophisticated campaign targeting government and financial systems across multiple continents. By leveraging a "split-model" LLM architecture, the operators automated key stages of the cyberattack lifecycle—from network reconnaissance and exploit development to the creation and iterative refinement of phishing infrastructure 【1】.

### **Who is Affected**
* **Governmental Entities:** Specific compromises were confirmed in **Afghanistan** (targeting a government application) and **Thailand** (targeting an administrative system). Reconnaissance was conducted against **Taiwanese** supply chain and manufacturing organizations, and **U.S.** government hosts (NASA) and local administrative bodies (D.C. Council, Delaware County, PA) were identified as targets for phishing preparation 【1】.
* **Financial Services:** A parallel campaign targeted billing and payment processing platforms across Europe, Australia, and Asia to extract credentials and administrative data 【1】.

### **Technical Details**
* **LLM Integration:** The attackers used **Claude Code** as an execution engine for agentic tasks like command execution, persistence, and task parallelization, while **DeepSeek-v4-pro** served as the reasoning engine for generating exploits and making strategic decisions 【1】.
* **Infrastructure:** The campaign utilized a network of Hong Kong-based servers. Primary tools included **TencShell** (a Go-based implant), **ARL** (for reconnaissance), and **DeepAudit** (for code vulnerability scanning) 【1】.
* **Malware:** Researchers identified a Linux/ARM 32-bit binary named `HSEWH-Ur`, which beacons over WebSocket and uses standard infrastructure-management API headers for authentication 【1】.

### **Security Implications**
This campaign demonstrates a shift from using LLMs as peripheral assistants to embedding them as core components of an attack workflow. This integration allows for rapid, automated iteration of exploits and phishing pages, lowering the barrier to entry for performing complex, multi-stage intrusions. The specific targeting of procurement and supply chain systems indicates a high-level intent to gain long-term intelligence on government policies and vendor relationships 【1】.

### **What Defenders Should Know**
* **Indicators of Presence:** Monitor for the use of tools like ARL, DeepAudit, and Vshell in conjunction with suspicious activity, particularly if linked to open directories on ports such as 8888 or 5003 【1】.
* **Infrastructure Patterns:** Watch for infrastructure clusters involving Hong Kong-based servers sharing SSH keys and TLS certificates, and be alert for `Gshell` and `TencShell` command-and-control frameworks 【1】.
* **Tactical Focus:** Attackers are prioritizing the exploitation of specific framework versions (e.g., Laravel) and the theft of cloud access keys and messaging platform credentials 【1】.
* **Detection Strategy:** Because LLMs enable rapid adaptation, defenders must focus on baseline behavior and anomaly detection—such as unusual automated scanning patterns or the sudden appearance of cloned login portals—rather than solely relying on static indicators like specific file hashes 【1】.
Introducing CylindricalCanine: The GoldenEyeDog subgroup responsible for the April DigiCert incident - Expel, Inc.

Thank you for the request. The summary provided above accurately captures the critical details of the **CylindricalCanine** (associated with **GoldenEyeDog**/APT-Q-27) incident as detailed in the Expel article.

The incident highlights a significant supply chain attack that underscores how threat actors compromise trusted entities—like a certificate provider—to facilitate malicious activity at scale by bypassing standard security trust indicators.

### Key Takeaways for Defenders

To effectively mitigate the risk posed by this group, organizations should focus on the following:

* **Implement Network Monitoring:** Given the group's use of specific WebSocket traffic, defenders should deploy detection logic (such as the Suricata rules provided by Expel) to monitor for connections over ports 5188 and 5198.
* **Analyze Endpoint Behavior:** Since the group relies on DLL sideloading and legitimate executable hijacking (e.g., `TASLogin`), endpoint security should be configured to flag suspicious child processes originating from trusted or common application folders.
* **Leverage Intelligence:** Integrate the list of 1,926 known malicious files associated with the **Golden Gh0st** malware family into your EDR/XDR blocklists.
* **Validate Code Provenance:** While signed binaries are generally considered trustworthy, this incident proves that signature verification alone is insufficient. Supplement signature validation with behavioral analysis to identify malicious intent even in signed files.
* **Strengthen Support Workflows:** As the initial access vector involved a support ticket, organizations should ensure that all files received through external support portals or ticketing systems are subject to mandatory sandboxing or automated analysis before being opened by staff.
DoNot (APT-C-35) Intrusion Targeting Bangladesh Military Personnel - Cyderes

This précis summarizes the report on the cyber-espionage campaign attributed to the threat actor known as the Howler Cell (or DoNot/APT-C-35) targeting the Bangladesh military.

### **Overview: What Happened**
The Howler Cell (DoNot/APT-C-35) conducted a targeted spear-phishing campaign against high-value individuals within the Bangladesh Air Force. The attackers leveraged sophisticated social engineering, using a document impersonating a biography of a real Air Force officer to trick targets into opening a malicious RTF file. Upon opening, the file executed a multi-stage infection process that beaconed to attacker infrastructure immediately 【1】.

### **Affected Targets**
The campaign targeted military personnel, specifically within the Bangladesh Air Force. This actor, assessed to be India-aligned, has a history of sustained espionage against military, government, and diplomatic targets across South Asia, including Pakistan, Bangladesh, and Sri Lanka 【1】.

### **Technical Details**
The infection chain is highly modular and designed to avoid detection:
* **Initial Access & Geofencing:** The RTF file uses remote template injection to fetch a malicious VBA macro. The C2 infrastructure is geofenced; it only delivers the weaponized payload to targets in the intended region, while delivering a benign decoy to others.
* **Execution & Persistence:** A VBA macro performs process injection using callback-based API abuse to deploy shellcode. This shellcode, which is XOR-encoded, ultimately drops a DLL implant that establishes persistence via a scheduled task disguised as "OneDrive telemetry."
* **C2 & Modular Delivery:** Communication with the C2 server occurs over HTTPS using AES-128-CBC encryption. The implant performs a two-phase handshake to register system details before the server delivers follow-on modules (such as `ejtest.dll`) based on the victim's profile.

### **Security Implications**
This campaign represents a focused intelligence-gathering operation. The ability of researchers to interact with the C2 endpoint and retrieve live second-stage modules confirms that the attackers are actively managing these compromises to collect sensitive data. The use of geofencing highlights a deliberate strategy to minimize the footprint of their infrastructure and evade analysis by security researchers outside the target region.

### **Guidance for Defenders**
Organizations should hunt for the following indicators:
* **Network Activity:** Monitor for HTTPS POST requests containing the parameters `mopd=` and `malp=`.
* **System Indicators:** Look for suspicious scheduled tasks that mimic "OneDrive" naming conventions. Investigate Office applications if they exhibit unusual behavior, such as spawning child processes or making external network connections.
* **Infrastructure:** Monitor for DNS queries to `.info` domains that utilize specific patterns, such as recurring prefixes (e.g., "reggy", "program") or themes like "updated," often combined with deliberate misspellings.

*Note: Further Indicators of Compromise (IOCs), such as specific file hashes and C2 infrastructure, are available in the appendix of the original report.*
TELEPUZ: a modular MaaS malware spreading via CLICKFIX-VIDAR chains - Elastic

TELEPUZ is an emerging, modular Malware-as-a-Service (MaaS) threat that has been active since late April 2026. It is distributed via a "ClickFix" social engineering campaign, which tricks users into manually executing malicious shell commands 【1】.

### What Happened
The infection chain starts when a user visits a malicious website and is prompted to copy and paste a PowerShell command into their terminal, ostensibly to view the page content 【1】. This command downloads and executes a VIDAR infostealer variant, which acts as a secondary stager to deploy the main TELEPUZ binary 【1】. TELEPUZ is currently in active development, characterized by frequent updates and a high volume of builds being uploaded to public analysis platforms 【1】.

### Who Is Affected
While the campaign is global, the malware includes anti-CIS geolocation checks, specifically avoiding systems with language identifiers (LCIDs) corresponding to countries like Ukraine, Belarus, Armenia, and others 【1】. The primary targets are likely Windows users susceptible to social engineering lures involving financial or service-related themes.

### Security Implications
TELEPUZ is a full-featured, modular threat capable of significant data theft and system control. Its capabilities include:
* **Financial Theft:** Using its WebInjector module, it can manipulate browser interactions (specifically targeting financial fields like IBANs) using the Chrome DevTools Protocol or WebDriver BiDi, rather than traditional hooking methods 【1】.
* **Broad Capability:** It supports modules for keylogging, cookie extraction from Chromium browsers, taking screenshots, and process management 【1】.
* **Evasion:** The malware employs advanced anti-analysis techniques, including indirect syscalls, unhooking `ntdll.dll`, patching security products (AMSI and ETW), and detecting debugging environments 【1】.

### Technical Details
* **Infrastructure:** The Command and Control (C2) infrastructure is robust, utilizing fallback methods including Telegram profiles, Steam usernames, DNS records, and a Polygon blockchain smart contract (which also acts as a kill switch) 【1】.
* **Code:** The core binary is a 64-bit Windows shared library written in C. It uses import hashing, string encryption (RC4), and junk instructions to hinder analysis 【1】.
* **Persistence:** It installs itself as a service and utilizes specific directories in `%AppData%` and `%ProgramData%` for persistence and execution 【1】.

### What Defenders Should Know
* **Detection:** Elastic Security Labs has provided a YARA rule (`Windows_Trojan_Telepuz.yar`) to assist in identifying this threat 【1】.
* **Behavioral Monitoring:** Defenders should look for the execution of PowerShell commands originating from unexpected sources, the creation of the `cfgmgr_mtx` mutex, and suspicious registry modifications related to services like `CipherAllocator` or `PilotmasterMast` 【1】.
* **Awareness:** Because the primary vector is user-facilitated (copy-pasting commands), end-user security awareness training regarding the risks of "ClickFix" social engineering is critical.
Tailscale: Tailscale SSH previously accepted usernames that contained a leading - character. On Linux platforms these usernames were passed as arguments to getent(1) leading to ACL bypass - Tailscale Inc.

Here is a detailed precis of the security vulnerability identified in Tailscale security bulletin **TS-2026-009**.

### **Overview**
A vulnerability existed in Tailscale SSH regarding the handling of command-line arguments. This flaw allowed an attacker who already possessed SSH access to a Linux node to bypass configured Access Control Lists (ACLs) and gain `root` user access 【1】.

### **Technical Details**
The issue stemmed from how usernames containing a leading hyphen (`-`) were processed on Linux systems. Tailscale SSH would pass these usernames as arguments to the `getent(1)` utility to retrieve corresponding entries from the `passwd` file.

Because `getent` interpreted these leading hyphens as command-line flags, it was possible to inject malicious arguments. For example, by connecting with the username `-i`, the system interpreted the input as the `--no-idn` flag. This caused `getent` to output the contents of the `passwd` file starting with the `root` user entry, which resulted in Tailscale erroneously initiating an interactive `root` session 【1】.

### **Impacted Users**
This vulnerability specifically affected users who met all of the following criteria:
* Utilized **Tailscale SSH**.
* Ran Tailscale on **Linux** hosts.
* Relied on `autogroup:nonroot` user restrictions defined within their Tailscale ACL policies 【1】.

### **Guidance for Defenders**
To remediate this vulnerability, Tailscale has implemented a fix that explicitly rejects any incoming usernames that begin with a leading dash.

* **Required Action:** Users of Tailscale SSH on Linux must upgrade their Tailscale installation to **version 1.98.9 or newer** to fully mitigate this issue 【1】.
cyber-decoy: Experimental Decoy Broker - secdev02

The `cyber-decoy` project is an open-source, containerized honeypot architecture designed to detect, log, and analyze unauthorized network activity by emulating common services (SSH, RDP, and SMB). It serves as a tool for security teams to gain visibility into attacker reconnaissance and exploitation attempts within their infrastructure.

### What Happened (Core Functionality)
The project provides a ready-to-deploy honeypot system that advertises specific services to attract potential attackers. It captures both network-level connection attempts and deeper interaction data (such as credentials used or files accessed) through a two-tier architecture.

### Who is Affected (Target Audience)
This project is intended for **security defenders, incident responders, and researchers** who manage private network infrastructure. It is not an attack tool, but rather a defensive instrument to be deployed on authorized infrastructure to monitor for malicious actors scanning or attempting to gain unauthorized access to an organization’s network.

### Security Implications
* **Strategic Visibility:** By using eBPF, the system monitors inbound traffic at the kernel level, allowing defenders to detect port scans even against ports that are not actively advertising a service.
* **Operational Isolation:** The architecture prioritizes containment. Decoys run on an isolated Docker network (`decoynet`) without direct internet or host access, limiting the potential for an attacker to break out or move laterally.
* **Data Correlation Necessity:** Because the public-facing broker proxies traffic to the internal decoys, the decoys cannot see the attacker's true source IP address. Defenders must correlate logs from the broker (IP data) with those from the decoys (session data) using timestamps to obtain a full picture of the attacker's activity.
* **Inherent Risk:** The project explicitly warns that decoys should be considered "potentially compromised" at all times and must be deployed only on infrastructure where such risks are acceptable and managed.

### Technical Details
* **Two-Tier Architecture:**
* **Broker:** Acts as the public-facing proxy. It utilizes an **eBPF TC (Traffic Control) classifier** to log every inbound TCP SYN packet. It then forwards traffic to the backend decoys.
* **Decoys:** Isolated containers running the actual services. `ssh-decoy` and `rdp-decoy` are powered by OpenCanary, while `smb-decoy` is a custom implementation using Impacket.
* **Prerequisites:** Requires a Linux host (ideally kernel 6.6+ for optimal eBPF support) and specific container capabilities (`NET_ADMIN`, `BPF`, `PERFMON`).
* **Environment:** Utilizes Docker Compose for deployment, with support for customizing banners and port mappings via `broker/config.yaml`.

### What Defenders Should Know
* **Deployment Constraints:** While development is possible on macOS (via Docker Desktop), the full eBPF-based observation capabilities are restricted within the LinuxKit VM environment.
* **Maintenance:** Security is critical; the custom SMB decoy uses a version of Impacket specifically selected to avoid known critical vulnerabilities (e.g., CVE-2021-31800). Defenders must ensure these dependencies remain patched.
* **Log Management:** Effective use of this tool requires a centralized logging or SIEM strategy to successfully correlate the broker's connection logs with the decoy's interaction logs for accurate attribution.
