APT41 Cyberespionage and Cybercrime – Structure and Operations

The APT41 Cyberespionage and Cybercrime group is believed to operate as a contractor or affiliate of the Chinese Ministry of State Security (MSS), with ties to regional cyber units. Unlike other nation-state groups, APT41 uniquely combines state-sponsored espionage with financially motivated cybercrime — including ransomware deployment, cryptocurrency theft, and illicit access to video game environments for profit. This hybrid approach enables the group to remain operationally flexible while continuing to deliver on geopolitical priorities set by state actors.

Attribution reports from the U.S. Department of Justice (DOJ) [DOJ 2020 Indictment] identify several named operatives associated with APT41, highlighting the structured and persistent nature of their operations. The group has demonstrated high coordination, advanced resource access, and the ability to pivot quickly between long-term intelligence operations and short-term financially motivated campaigns.

APT41 appears to operate with a dual-hat model: actors perform espionage tasks during official working hours and engage in financially driven attacks after hours. Reports suggest the use of a shared malware codebase among regional Chinese APTs, but with distinct infrastructure and tasking for APT41.

In September 2020, the U.S. Department of Justice publicly indicted five Chinese nationals affiliated with APT41 for a global hacking campaign. Although not apprehended, these indictments marked a rare instance of legal attribution against Chinese state-linked actors. The group’s infrastructure, tactics, and timing patterns (active during GMT+8 working hours) strongly point to a connection with China’s Ministry of State Security (MSS).

APT41 Cyberespionage and Cybercrime – Chrome V8 Exploits

In early 2025, APT41 was observed exploiting a zero-day vulnerability in the Chrome V8 JavaScript engine, identified as CVE-2025-6554. This flaw allowed remote code execution through malicious JavaScript payloads delivered via watering-hole and spear-phishing campaigns.

This activity demonstrates APT41’s increasing focus on client-side browser exploitation to gain initial access and execute post-exploitation payloads in memory, often chained with credential theft and privilege escalation tools. Their ability to adapt to evolving browser engines like V8 further expands their operational scope in high-value targets.

Freemindtronic’s threat research confirmed active use of this zero-day in targeted attacks on European government agencies and tech enterprises, reinforcing the urgent need for browser-level monitoring and hardened sandboxing strategies.

TOUGHPROGRESS Calendar C2 (May 2025)

In May 2025, Google’s Threat Intelligence Group (GTIG), The Hacker News, and Google Cloud confirmed APT41’s abuse of Google Calendar for command and control (C2). The technique, dubbed TOUGHPROGRESS, involved scheduling encrypted events that served as channels for data exfiltration and command delivery. Google responded by neutralizing the associated Workspace accounts and Calendar instances.

Additionally, Resecurity published a June 2025 report confirming continued deployment of TOUGHPROGRESS on a compromised government platform. Their analysis revealed sophisticated spear-phishing methods using ZIP archives with embedded LNK files and decoy images.

To support detection, SOC Prime released Sigma rules targeting calendar abuse patterns, now incorporated by leading SIEM vendors.

Mitigation and Detection Strategies

  • Update Management: proactive patching of CVEs (Citrix, Log4j, Chrome V8), rapid deployment of security fixes.
  • UEFI/TPM Protection: enable Secure Boot, verify firmware integrity, use HSMs to isolate cryptographic keys from OS-level access.
  • Cloud Surveillance: behavioral monitoring for abuse of Google Calendar, Drive, Sheets, and Cloudflare Workers via SIEM and EDR systems.
  • Memory-based Detection: YARA and Sigma rules targeting DUSTPAN, DEAD EYE, and TOUGHPROGRESS malware families.
  • Advanced Detection: apply Sigma rules from SOC Prime for identifying C2 anomalies via calendar-based techniques.
  • Network Isolation: enforce segmentation and air gaps for sensitive environments; monitor DNS and TLS outbound patterns.
  • Browser-level Defense: enable Chrome’s Site Isolation mode, enhance sandboxing, monitor abnormal JavaScript calls to the V8 engine.
  • Key Isolation: use hardware HSMs like DataShielder to prevent unauthorized in-memory key access.
  • Network TLS profiling: Alert on unknown certificate chains or forged CAs in outbound traffic.

Malware and Tools

  • MoonBounce: UEFI bootkit linked to APT41, detailed by Kaspersky/Securelist.
  • DUSTPAN / DUSTTRAP: Memory-resident droppers observed in a 2023 campaign.
  • DEAD EYE, LOWKEY.PASSIVE: Lightweight in-memory backdoors.
  • TOUGHPROGRESS: Abuses Google Calendar for C2, used in a late-2024 government targeting campaign.
  • ShadowPad, PineGrove, SQLULDR2: Advanced data exfiltration tools.
  • LOWKEY/LOWKEY.PASSIVE: Lightweight passive backdoor used for long-term surveillance.
  • Crosswalk: Malware for targeting both Linux and Windows in hybrid cloud environments.
  • Winnti Loader: Shared component used to deploy payloads across various Chinese APT groups.
  • DodgeBox – Memory-only loader active since 2025 targeting EU energy sector, using PE32 x86 DLL signature evasion.
  • Lateral Movement: Cobalt Strike, credential theft, Winnti rootkits, and legacy exploits like PrintNightmare (CVE-2021-34527).

Possible future threats include MoonWalk (UEFI-EV), a suspected evolution of MoonBounce, targeting firmware in critical systems (e.g., Gigabyte and MSI BIOS), as observed in early 2025. Analysts should anticipate deeper firmware-level persistence across high-value targets.

Use of Cloudflare Workers, Google APIs, and short-link redirectors (e.g., reurl.cc) for C2. TLS via stolen or self-signed certificates.

APT41 Cyberespionage and Cybercrime Motivations and Global Targets

Introduction to the APT36 Cyberespionage Group

The Advanced Persistent Threat (APT) group known as APT36, Transparent Tribe, and Mythic Leopard has been an active cyber espionage actor for several years. Primarily targeted at India, APT36 is notorious for its persistent campaigns to collect sensitive intelligence from a variety of organizations, including government, military, and potentially the research and education sectors. Their operations are often characterized by the use of sophisticated spearphishing techniques and bespoke malware, such as Poseidon, Crimson RAT, ElizaRAT, and CapraRAT. The purpose of this reference document is to compile and analyze the available information about APT36, its tactics, techniques, and procedures (TTPs), infrastructure, and recommended mitigation measures.

History and Evolution of the APT36 Cyberespionage Group

Freemindtronic Andorra focuses its initial analysis on recent IOCs (2023-2025), but APT36 has been active for several years. Reports from other security organizations confirm that cyber espionage campaigns targeting Indian entities began as early as 2016. Over time, APT36 has continuously adapted its TTPs, refining techniques to bypass security measures and develop new infiltration tools. For example, the emergence of Android RATs like CapraRAT expands their reach to mobile devices, increasing the risk for smartphone users. Meanwhile, leveraging platforms such as Telegram for C2 operations (ElizaRAT) indicates an attempt to exploit less monitored communication channels, enhancing their stealth capabilities.

Cybersecurity experts continue to debate APT36’s precise attribution. Although its primary targets are in India, certain indicators suggest possible connections to Pakistani state interests. The choice of decoy themes and the sectors under attack reinforce this hypothesis. However, formal attribution remains challenging, requiring deeper analysis and more conclusive evidence. In the complex world of cyber threat intelligence, determining the true origin of APT groups demands a meticulous and multi-layered approach.

Techniques, Tactics and Procedures (TTPs) Employed by APT36

Reconnaissance: APT36 likely conducts careful reconnaissance of its targets, collecting publicly available information (OSINT) on employees, organizational structures, and sensitive projects. Social media profiles and official websites are potential sources of information. Social engineering can also be used to obtain information from employees.

Initial point of entry:
  • Spearphishing: This is APT36’s preferred attack vector. Emails are meticulously designed to mimic legitimate communications (e.g., government notifications, invitations to academic events, security app updates). Malicious attachments (Word documents, PDFs, executables, RTF files, screensavers) or links to compromised websites are used to distribute the initial payloads. Identified filenames (e.g., Briefing_MoD_April25.docx, Alert_Kavach_Update.exe) illustrate this tactic by targeting topical themes or topics relevant to potential victims.
  • Exploiting Vulnerabilities: Although not explicitly mentioned in the initial IOCs, it is possible that APT36 could exploit known software vulnerabilities in commonly used applications (e.g., Microsoft Office) to gain initial access. RTF files are often used in such attempts.
  • Website Compromise: It is possible, although not directly proven by IOCs, that APT36 could compromise legitimate websites to host payloads or to redirect victims to phishing pages.
Persistence:

Once a system is compromised, APT36 puts mechanisms in place to maintain access even after a reboot. IOCs reveal the use of specific Windows registry keys (HKEY_CURRENT_USERSoftwareCrimsonRAT, HKEY_LOCAL_MACHINESYSTEMElizaRATPersistence, HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionRunCapraStart) to ensure the automatic execution of malware. On Android, persistence is often achieved by masquerading as legitimate app updates (com.kavach.update.apk).

Lateral Movement:

After obtaining an initial foothold, APT36 attempts to move laterally within the victim’s network to reach more sensitive systems. This can involve exploiting network shares, using stolen credentials (potentially obtained via keylogging), and executing remote commands via deployed RATs.

Command and Control (C2)

The malware used by APT36 communicates with attacker-controlled C2 servers to receive instructions and exfiltrate data. The identified IP addresses (45.153.241.15, 91.215.85.21, etc.) potentially represent this C2 infrastructure. ElizaRAT’s use of TelegramBot suggests leveraging popular messaging platforms for C2, which can make detection more difficult. HTTP and HTTPS are likely used for C2 traffic, potentially hidden within legitimate web traffic.

Data exfiltration

Since APT36’s primary focus is espionage, data exfiltration is a crucial step. The types of data targeted likely include sensitive documents (military, government, research), credentials (usernames, passwords), and other strategic information. Data can be exfiltrated through established C2 channels, potentially compressed, or encrypted to avoid detection.

APT36 Malware and Tools

The APT36 Cyberespionage Group relies on various Remote Access Trojans (RATs) for espionage operations, especially on Indian targets.

  • Poseidon malware: A sophisticated RAT with extensive espionage and data theft capabilities. Its hash (3c2cfe5b94214b7fdd832e00e2451a9c3f2aaf58f6e4097f58e8e5a2a7e6fa34) allows it to be identified on compromised systems.
  • Crimson RAT: Another RAT commonly associated with APT36, offering keylogging, screen capture, and remote command execution features. Its mutex (GlobalCrimsonRAT_Active) and registry key (HKEY_CURRENT_USERSoftwareCrimsonRAT) are important indicators.
  • ElizaRAT: This RAT appears to be using Telegram for C2 communication, which is a potential evasion tactic. Its loader (9f3a5c7b5d3f83384e2ef98347a6fcd8cde6f7e19054f640a6b52e61672dbd8f) and its mutex (LocalElizaRATSession) are key IOCs.
  • CapraRAT (Android): Indicates APT36’s ability to target mobile devices. Its features can include stealing SMS, contacts, audio recording, and location tracking. Its package name (com.kavach.update.apk) and mutex (SessionsBaseNamedObjectsCapraMobileMutex) are specific flags.

Obfuscation and Evasion: APT36 uses a variety of techniques to make its malware and communications more difficult to detect and analyze. Examples of these tactics include Base64 encoding of sensitive information (bXlQYXNzd29yZDEyMw==, JAB1c2VyID0gIkFkbWluIg==) and obfuscation of JavaScript code (eval(decodeURIComponent(‘%75%70%64%61%74%65’))) are examples of these tactics.

APT36 Cyberespionage Group Infrastructure

APT36’s infrastructure includes the command and control (C2) servers used to direct malware deployed on victims’ systems. The identified IP addresses (45.153.241.15, 91.215.85.21, 185.140.53.206, 192.241.207.45, 103.145.13.187) are focal points for blocking and monitoring. Analysis of these IP addresses can reveal information about the hosting providers used and potentially other related activities. Malicious domains (kavach-app[.]com, indiapost-gov[.]org, gov-inportal[.]org, indian-ministry[.]com, securekavach[.]in) are used in phishing campaigns to host fake login pages or to distribute malware. These domains often imitate legitimate websites to trick victims. Analyzing the registration information of these domains can sometimes provide clues about the actors behind these activities. It is also possible that APT36 is using compromised servers as relays to hide the origin of its attacks and make tracing more difficult.

Motivations and Targets of the APT36 Cyberespionage Group

The main motivation for APT36 appears to be cyber espionage, with a particular interest in gathering strategic intelligence related to India. Typical targets include:

  • Indian government entities (ministries, agencies).
  • Military and defense organizations.
  • Research institutes and universities.
  • Telecommunications companies.
  • Potentially other sectors considered strategically important.

The themes of phishing lures (defense, foreign affairs, security updates of government applications) reinforce this assessment of targets and motivations.

Mitigation and Detection Measures Against the APT36 Cyberespionage Group

Mitigating threats from the APT36 Cyberespionage Group requires layered defenses, active monitoring, and awareness training.

General recommendations:
  • Awareness of the threat of spearphishing: Train employees to identify suspicious emails, verify the authenticity of senders, and not click on links or open attachments from unknown or unsolicited sources.
  • Implement multi-factor authentication (MFA): Strengthen account security by requiring a second form of authentication in addition to the password.
  • Keeping systems and software up to date: Regularly apply security patches for operating systems, applications, and web browsers to reduce the risk of vulnerability exploitation.
  • Network segmentation: Limit the spread of threats by segmenting the network and enforcing strict access control policies.
  • Network traffic and log monitoring: Implement monitoring systems to detect suspicious network activity, communications to known IP addresses and C2 domains, and unusual access attempts. Regularly analyze system and application logs.
  • Use robust security solutions: Deploy and maintain anti-virus solutions, endpoint detection and response (EDR) systems, and intrusion prevention and detection (IDS/IPS) systems.
Specific measures based on IOCs:
  • IOC Blocking: Integrate identified IP addresses, domains, and file hashes into firewalls, DNS servers, antivirus solutions, and web filtering systems to block communications and malware associated with APT36.
  • Rule-Based Detection: Implement Yara and Sigma rules (if available) to identify patterns and characteristics of malware and APT36 activities on systems and in logs.
  • Traffic Inspection: Configure security systems to inspect network traffic for suspicious user agents (APT36Client/1.0, TelegramBot-ElizaRAT/2.5, CapraAndroidAgent/1.4).
  • Registry and Mutex Monitoring: Use endpoint monitoring tools to detect the creation of registry keys and mutexes associated with RATs used by APT36.
  • Email Scanning: Implement spam filters and email scanning solutions to identify and block messages containing known file names and phishing URLs.
  • Mobile device security: Deploy mobile security solutions and educate users about the risks of installing apps from unknown sources. Monitor Android devices for the presence of malicious package names.
Incident response strategies:
  • Response Plan: Develop and maintain a cybersecurity incident response plan specific to APT threats, including steps to follow in the event of detection of APT36-related activity.
  • Isolation: In the event of a suspected compromise, immediately isolate the affected systems from the network to prevent the spread of the attack.
  • Forensic Analysis: Perform in-depth forensic analysis to determine the scope of the breach, identify compromised data, and understand the tactics used by attackers.
  • Eradication: Completely remove malware, persistence mechanisms, and tools used by attackers from compromised systems.
  • Restore: Restore systems and data from clean, verified backups.
  • Lessons learned: After an incident, analyze causes and processes to improve security measures and response procedures.

APT29 SpearPhishing Europe: A Stealthy LongTerm Threat

APT29 spearphishing Europe campaigns highlight a persistent and highly sophisticated cyberespionage threat orchestrated by Russia’s Foreign Intelligence Service (SVR), known as Cozy Bear. Active since at least 2008, APT29 has become synonymous with stealthy operations targeting European institutions through phishing emails, Microsoft 365 abuse, supply chain compromises, and persistent malware implants. Unlike APT28’s aggressive tactics, APT29’s approach is patient, subtle, and highly strategic—favoring covert surveillance over immediate disruption. This article examines APT29’s tactics, European targeting strategy, technical indicators, and how sovereign solutions like DataShielder and PassCypher help organizations defend against Russian longterm cyber espionage campaigns.

APT29’s Persistent Espionage Model: The Art of the Long Game in Europe

APT29’s operational model is defined by stealth, longevity, and precision. Their goal is not shortterm chaos but sustained infiltration. Their campaigns frequently last months—or years—without being detected. APT29 rarely causes disruption; instead, it exfiltrates sensitive political, diplomatic, and strategic data across Europe.

APT29 often custombuilds malware for each operation, designed to mimic legitimate network activity and evade common detection tools.

Covert Techniques and Key Infiltration Methods

APT29’s longterm access strategy hinges on advanced, covert methods of penetration and persistence:

Custom Backdoors

Backdoors like “WellMess” and “WellMail” use encrypted communications, steganography, and cloud services to evade inspection. They also include antianalysis techniques such as antiVM and antidebugging code to resist forensic examination.

Supply Chain Attacks

The SolarWinds Orion attack in 2020 remains one of the largest breaches attributed to APT29. This compromise of the supply chain allowed attackers to infiltrate highvalue targets via trusted software. The SUNBURST and TEARDROP implants enabled stealthy lateral movement.

SpearPhishing from Compromised Diplomatic Sources

APT29’s phishing operations often originate from hijacked diplomatic email accounts, lending legitimacy to phishing attempts. These emails target government bodies, international organizations, and embassies across Europe.

Credential Harvesting via Microsoft 365

APT29 abuses cloud infrastructure by executing OAuth consent phishing, targeting legacy authentication protocols, and compromising user credentials to access SharePoint, Outlook, and cloudstored documents.

GRAPELOADER and WINELOADER: New Malware Lures in 2025

In April 2025, APT29 launched a phishing campaign dubbed SPIKEDWINE, impersonating a European Ministry of Foreign Affairs and inviting victims to fake winetasting events. These emails, sent from domains like bakenhof[.]com and silry[.]com, delivered malware via a file named “wine.zip.”

The attack chain begins with GRAPELOADER, a previously undocumented loader, followed by a new variant of the WINELOADER backdoor. This multistage infection shows evolving sophistication in malware design, timing of payload execution, and evasion techniques. The campaign’s targets include multiple European Ministries of Foreign Affairs and nonEuropean embassies in Europe.

Geopolitical Implications of APT29’s European Operations

APT29’s spear-phishing activities are not just technical threats—they are instruments of Russian geopolitical strategy. The group’s consistent targeting of ministries, embassies, and think tanks across Europe aligns closely with key diplomatic and policy moments.

APT29’s operations often intensify ahead of European elections, EU-NATO summits, or major sanctions announcements. Their goal is not only to steal sensitive intelligence, but to subtly influence policymaking by gaining access to classified assessments, private negotiations, or internal dissent.

Notable examples include:

APT29 acts as a digital vanguard for Russian hybrid warfare, where cyber operations feed into diplomatic leverage, information warfare, and strategic disruption. Understanding this broader agenda is crucial for shaping European cyber defense beyond the technical dimension.

European Government Responses to APT29: A Patchwork Defense

Infographic showing European government responses to APT29 spear-phishing Europe, including attribution, legal action, and cyber strategy.

This comparison illustrates the fragmented nature of Europe’s institutional responses to state-sponsored cyber threats. While some nations have clearly identified and named APT29, others remain more cautious or reactive.

What if APT29 Had Not Been Detected?

While some operations were eventually uncovered, many persisted for months or years. Had APT29 remained entirely undetected, the implications for Europe’s political and strategic landscape could have been far-reaching:

  • Diplomatic Blackmail: With access to confidential negotiations, APT29 could have leaked selective intelligence to disrupt alliances or blackmail key figures.
  • Policy Manipulation: Strategic leaks before elections or summits could steer public opinion, weaken pro-EU narratives, or stall collective defense decisions.
  • NATO Cohesion Threats: Exfiltrated defense policy data could be used to exploit divisions between NATO member states, delaying or undermining unified military responses.
  • Influence Campaign Fuel: Stolen data could be recontextualized by Russian disinformation actors to construct persuasive narratives tailored to fracture European unity.

This scenario highlights the necessity of early detection and sovereign countermeasures—not merely to block access, but to neutralize the geopolitical utility of the exfiltrated data.

Notable APT29 Incidents in Europe

Date Operation Name Target Outcome
2015 CozyDuke U.S. & EU diplomatic missions Long-term surveillance and data theft
2020 SolarWinds EU/US clients (supply chain) 18,000+ victims compromised, long undetected persistence
