Certified: The Security+ Prepcast

In this episode, we are exploring some of the key motivations behind cyberattacks. Understanding what drives attackers is just as important as knowing how they operate. Their goals shape their tools, their targets, and the urgency of your defensive response. We will focus on four common motivations: data exfiltration, espionage, service disruption, and blackmail.
Let’s start with data exfiltration. This is the unauthorized copying, transfer, or retrieval of data from a system. In simple terms, it means someone is stealing information. Attackers may target personal data, financial records, proprietary software, intellectual property, or classified government files. The goal is usually to profit from the stolen data or to damage the victim organization.
Typical scenarios include attackers gaining access to an internal network and quietly transferring out files over time. They may use encrypted channels to avoid detection or disguise the stolen data as harmless traffic. Data exfiltration can happen through malware, compromised accounts, insider actions, or even unsecured cloud services.
The consequences of data exfiltration can be severe. Companies may lose trade secrets, suffer reputational damage, or face regulatory fines. Customers may become victims of identity theft. Governments may lose classified or sensitive intelligence.
One notable case involved a major credit reporting agency where attackers exfiltrated the personal data of over one hundred forty million individuals. Names, addresses, social security numbers, and financial data were exposed. The breach led to investigations, lawsuits, and massive costs to repair the damage. That incident serves as a reminder that data protection is not just about prevention—it is about detecting and responding quickly to exfiltration attempts.
Now let’s examine espionage. Cyber-espionage is the use of digital tools to gather intelligence, often by nation-state actors or highly motivated groups. Unlike data exfiltration for financial gain, espionage is focused on long-term strategic advantage. Targets may include government agencies, military operations, research labs, and large corporations.
The goal of espionage is to access confidential data without detection. This could include defense strategies, foreign policy documents, technical designs, or confidential negotiations. Espionage campaigns are often subtle and persistent. They may go undetected for months or even years while attackers silently gather information.
A real-world example of cyber-espionage occurred when a group linked to a foreign government compromised a U.S. defense contractor and spent months exfiltrating files related to weapons development. The attackers used spear phishing and custom malware to gain access and establish a foothold. Because the goal was intelligence gathering—not immediate damage—the breach remained hidden until a routine audit uncovered unusual data traffic patterns.
Espionage threats require strong detection systems, insider awareness, and a deep understanding of normal network behavior. Organizations that deal with sensitive or strategic information must stay alert to these long-term, low-noise threats.
Now let’s move to service disruption. This motivation focuses not on stealing data but on taking services offline or making them unreliable. One of the most common techniques used in service disruption is the distributed denial of service attack. In this type of attack, the attacker floods a server, network, or service with massive amounts of traffic to overwhelm its resources and make it unavailable to users.
Service disruption attacks may be carried out by hacktivists, competitors, or nation-state groups. Their targets often include financial institutions, government portals, online retailers, and healthcare systems. These sectors are especially vulnerable because downtime can cause immediate and serious consequences.
Case studies include attacks against public transportation systems that disrupted ticketing and schedules, or denial-of-service attacks on emergency communication networks that delayed critical responses. In one high-profile example, attackers targeted a major DNS provider, making dozens of popular websites unavailable for hours. The impact was felt globally, and businesses lost revenue as users were unable to reach services.
Mitigation strategies include using content delivery networks to absorb traffic, implementing rate limiting to block suspicious patterns, and working with internet service providers to filter out malicious requests. Many organizations also use web application firewalls and cloud-based security providers to reduce the risk of successful denial-of-service campaigns.
The final motivation we will explore today is blackmail. In cybersecurity, blackmail typically involves threatening to expose sensitive data or disrupt services unless a ransom is paid. This is often seen in ransomware attacks where files are encrypted, and victims must pay to regain access. In other cases, attackers may steal data and threaten to release it publicly unless demands are met.
The motivation behind blackmail is usually financial. Attackers target hospitals, schools, law firms, and others who may be willing to pay quickly to avoid disruption or embarrassment. However, blackmail can also be used for political leverage or personal revenge.
Recent incidents show how effective blackmail can be. In one case, a ransomware group attacked a city’s public records office and encrypted files related to property ownership and court filings. The attackers demanded payment in cryptocurrency and threatened to delete the data permanently if the ransom was not paid. In another example, attackers stole sensitive emails from a corporate executive and demanded payment to prevent publication.
These cases show why organizations must prepare for extortion scenarios. Backups, encryption, incident response plans, and employee training are all essential defenses. The ability to restore systems and continue operations without paying the ransom often determines the outcome of these attacks.
As you prepare for the Security Plus exam, make sure you can identify the motivations behind different types of cyberattacks. Understand that data exfiltration focuses on stealing information, espionage focuses on gathering strategic intelligence, service disruption targets availability, and blackmail uses threats for leverage. The exam may give you a scenario describing the attacker’s behavior and ask you to determine what motivates them. Pay attention to clues such as the type of data targeted or the actions the attacker takes after gaining access.
