Execution:
• T1204.002 – User Execution: Malicious File: Victims manually execute a disguised Lumma payload, often packed in a ZIP or disguised as a legitimate installer.
Persistence:
• T1547.001 – Registry Run Keys/Startup Folder: Modifies registry keys or startup folders to maintain persistence across system reboots.
• T1053.005 – Scheduled Task: Creates scheduled tasks to ensure malware re-executes after a reboot.
Privilege Escalation:
• T1055 – Process Injection: Injects malicious code into legitimate processes to escalate privileges and evade detection.
Defence Evasion:
• T1027 – Obfuscated Files or Information: Uses code obfuscation and string encryption to hide functionality from antivirus tools.
• T1497 – Virtualisation/Sandbox Evasion: Checks for virtual environments to avoid analysis and evade detection.
Credential Access:

Latrodectus Ransomware
Latrodectus is a sophisticated Windows-based malware loader first identified in October 2023. Designed to infiltrate systems stealthily, it facilitates the deployment of additional malicious payloads, including ransomware, remote access trojans, and information stealers. Its advanced evasion techniques and ability to execute code within legitimate process memory make it particularly dangerous, enabling activities such as data theft, remote system control, and disruption of critical operations. By masquerading legitimate files and employing complex obfuscation methods, Latrodectus poses a significant threat to the cybersecurity of both individuals and organisations.
Detailed Tactics, Techniques, and Procedures (TTPs):
- Initial Access and Execution:
- Latrodectus is primarily distributed through phishing emails containing malicious attachments or links. These emails often masquerade as legitimate communications, enticing recipients to open attachments or click on links that initiate the infection chain.
- Defence Evasion:
- The malware employs various techniques to evade detection, including:
- Debugger Evasion (T1622): Detects the presence of debugging tools to thwart analysis.
- Deobfuscation/Decode Files or Information (T1140): Deobfuscates encrypted strings to conceal its true functionality.
- The malware employs various techniques to evade detection, including:
- Persistence Mechanisms:
- Latrodectus establishes persistence through:
- Boot or Logon Autostart Execution via Registry Run Keys/Startup Folder (T1547.001): Modifies registry keys to ensure execution upon system startup.
- Scheduled Tasks (T1053.005): Creates tasks to execute malicious payloads at specified intervals.
- Latrodectus establishes persistence through:
- Command-and-Control (C2) Communication:
- Utilises standard application layer protocols for C2 communication, including:
- Application Layer Protocol: Web Protocols (T1071.001): Sends registration information to C2 servers via HTTP POST requests.
- Data Encoding: Standard Encoding (T1132.001): Employs Base64 encoding for data transmitted to C2 servers.
- Utilises standard application layer protocols for C2 communication, including:
- Discovery and Information Gathering:
- Conducts various discovery activities to gather system information:
- Account Discovery: Domain Account (T1087.002): Identifies domain administrator accounts by executing commands like net group "Domain Admins" /domain.
- System Information Discovery (T1082): Collects data on system configurations and settings.
- Conducts various discovery activities to gather system information:
- Impact:
- Capable of downloading and executing additional payloads, leading to:
- Data Encrypted for Impact (T1486): Facilitates ransomware deployment to encrypt critical data.
- Inhibit System Recovery (T1490): Disables system recovery features to prevent restoration of encrypted files.
- Capable of downloading and executing additional payloads, leading to:

- 524a8891a7df50aa9ced2da9ef379929
Mitigation Strategies:
- Email Security:
- Advanced Filtering: Implement sophisticated email filtering solutions to detect and block phishing emails containing malicious attachments or links.
- User Awareness Training: Educate employees on recognising phishing attempts and the dangers of interacting with unsolicited attachments or links.
- Endpoint Protection:
- Antivirus and Anti-malware: Deploy robust endpoint detection and response (EDR) solutions to identify and mitigate malicious activities associated with Latrodectus. Regularly update antivirus definitions to detect and remove known Latrodectus variants.
- Application Control: Restrict the execution of unauthorised applications and scripts to prevent malware installation.
- Network Security:
- Traffic Monitoring: Monitor network traffic for signs of command-and-control (C2) communication, particularly unusual HTTP POST requests or Base64-encoded data transmissions.
- Intrusion Detection and Prevention Systems (IDPS): Implement IDPS to block known indicators of compromise (IOCs) and suspicious activities.
- System Hardening:
- Regular Patching: Keep operating systems and applications up to date with the latest security patches to mitigate vulnerabilities exploited by Latrodectus.
- Access Controls: Enforce the principle of least privilege, ensuring users have only the access necessary for their roles.
- Backup and Recovery:
- Regular Backups: Conduct regular backups of critical data and ensure backups are stored securely and are not accessible from the main network.
- Recovery Planning: Develop and regularly update incident response and disaster recovery plans to quickly address infections and restore operations.
By implementing these strategies, organisations can enhance their defences against Latrodectus and similar malware threats.
Ransomware Victims Worldwide
A recent ransomware analysis reveals that the United States continues to be the most heavily impacted nation, accounting for a staggering 56.38% of global incidents. This underscores the ongoing vulnerability of US-based entities across various sectors to sophisticated ransomware threats.
Canada follows as the second-most affected country, reporting 5.37% of incidents, while France accounts for 4.70%, highlighting growing ransomware risks across North America and Western Europe. The United Kingdom (3.36%), India (2.01%), Australia (2.01%), and Japan (2.01%) also reported notable incident volumes, reflecting a broadening global threat footprint.
Other nations with a moderate percentage of ransomware incidents include Spain (2.01%), Italy (2.01%), Turkey (2.01%), Germany (2.01%), and Brazil (1.34%). Countries such as Pakistan, Argentina, Colombia, China, Thailand, Mexico, Hungary, and Iraq each reported between 0.67% and 1.34% of global cases.
Additional countries impacted include Netherlands, Singapore, Slovakia, Chile, Korea, Egypt, Morocco, Malaysia, Israel, Dominican Republic, Sweden, and Antigua and Barbuda, each contributing 0.67% of global ransomware cases.
This analysis underscores the increasingly global nature of ransomware attacks, with a continued focus on North America, Europe, and Asia. The findings emphasise the urgent need for proactive cybersecurity defences, cross-border threat intelligence sharing, and resilient recovery planning to mitigate these growing threats.
Ransomware Victims by Industry
In the most recent industry-specific analysis of ransomware incidents, the Manufacturing sector once again emerged as the top target, accounting for 13.42% of global attacks. This highlights persistent vulnerabilities in industrial networks, production systems, and supply chain ecosystems.
Business Services followed closely at 12.08%, indicating the high risk to service-oriented and consulting sectors. The Construction industry reported 9.40% of incidents, underscoring continued exposure among infrastructure and development firms.
Other significantly affected industries include Retail (8.05%), Healthcare (6.04%), and Education (6.04%), illustrating the risks to sectors dealing with sensitive consumer, patient, and student data. Transportation, Finance, and Organisations each reported 4.70% of total ransomware incidents, while Hospitality accounted for 4.03%, reflecting cybercriminals’ focus on public-facing services and essential logistics.
Sectors like Law Firms (3.36%), Federal (3.36%), Energy (3.36%), and Real Estate (2.68%) also experienced notable targeting, showing attackers' interests in sensitive legal, operational, and strategic data.
Emerging trends show ransomware also targeting IT (2.01%), Telecommunications (2.01%), and Minerals & Mining (2.01%). Industries like Electronics, Consumer Services, Agriculture, and Insurance each saw 1.34% or less, indicating that no vertical is immune.
This analysis confirms that ransomware remains an indiscriminate threat, affecting both critical infrastructure and private enterprises. It highlights the urgent need for industry-specific threat modeling, enhanced detection frameworks, and resilience strategies to counteract ransomware's evolving tactics.
