Organized crime is a term that describes groups of criminals who operate in a coordinated and systematic manner to pursue illicit activities for profit. Organized crime groups often use sophisticated tools and techniques to evade law enforcement and exploit vulnerabilities in various sectors, such as finance, transportation, or healthcare. Organized crime groups may also collaborate with other criminal groups or actors to share resources, information, or expertise.

Ransomware as a service (RaaS) is an example of a business model used by organized crime groups to conduct ransomware and extortion attacks. RaaS is an arrangement between an operator, who develops and maintains the tools to power extortion operations, and an affiliate, who deploys the ransomware payload. When the affiliate conducts a successful ransomware and extortion attack, both parties profit. The RaaS model lowers the barrier to entry for attackers who may not have the skill or technical wherewithal to develop their own tools but can manage ready-made penetration testing and sysadmin tools to perform attacks12.

Insider threat is a term that describes individuals who have legitimate access to an organization’s systems or data and use it for malicious purposes, such as theft, sabotage, or espionage. Insider threats may be motivated by various factors, such as greed, revenge, ideology, or coercion. Insider threats may also be unintentional, such as when an employee falls victim to phishing or social engineering.

Hacktivist is a term that describes individuals or groups who use hacking or cyberattacks to promote a political or social cause. Hacktivists may target governments, corporations, or other entities that they perceive as oppressive, corrupt, or unethical. Hacktivists may also use cyberattacks to expose information, disrupt services, or deface websites.

Nation-state is a term that describes a sovereign state that has a centralized government and a defined territory. Nation-state actors are individuals or groups who conduct cyberattacks on behalf of or with the support of a nation-state. Nation-state actors may target other states, organizations, or individuals for various reasons, such as espionage, sabotage, influence, or retaliation.

Documenting the collection and requiring a sign-off when possession changes are essential steps for maintaining chain of custody during an investigation. Chain of custody is the process of documenting and preserving the integrity and authenticity of evidence from the time it is collected until it is presented in court. Documenting the collection involves recording information such as date, time, location, description, serial number, etc., of the evidence. Requiring a sign-off when possession changes involves obtaining signatures from every person who handles or transfers the evidence.

The SIEM log shows that the user opened an email attachment named “Invoice.xlsx” and then executed a PowerShell script that downloaded and ran a malicious file from a remote server. This indicates that the attacker was able to bypass the application approve list by emailing a spreadsheet attachment with an embedded PowerShell in the file. This is a common technique used by malware authors to evade detection and deliver their payloads1.

Segmentation is a security technique that divides a network into smaller subnetworks or segments based on criteria such as function, role, location, etc. Segmentation can help mitigate the risk of unauthorized access or data leakage by isolating different segments from each other and applying different security policies and controls to each segment. Segmentation can help the security manager to implement a mitigation while maintaining alerting capabilities by separating the smart generator from the internal file server and allowing only necessary communication between them.
