![]() Insecure cloud interfaces can provide internal threat actors with a convenient way to exfiltrate data. Organizations should use email monitoring tools and scanners to detect and prevent outbound emails carrying sensitive data. Attackers can use emails to send sensitive information to external recipients, as well as embed malicious links or files in messages that can compromise the recipient's computer. Outbound email is another common exfiltration technique. It involves transferring sensitive information from a secure network onto an insecure device, such as a laptop or USB drive - these devices are often not protected by the organization's security measures, leaving them vulnerable to attack. Downloads to insecure devices and networksĭownloading data to insecure devices or networks is another common form of data exfiltration. Organizations must implement strong access controls and conduct regular risk assessments to identify and mitigate the risk of insider threats. A malicious insider can also deliberately copy and remove data just to cause harm or gain some other form of benefit. They might be tempted to take shortcuts to save time. Insider threats may appear in two main ways, negligent internal employees and malicious insiders.įor example, an employee may become negligent with their data handling over time after performing some mundane and repetitive task. Examples of malicious insider threats include changing file names and extensions to obscure the value of data being transferred and taking data to gain an advantage in a new role. ![]() Insider threats and negligent employees pose a significant risk to an organization's data security, as they have authorized access to sensitive data and can use it for malicious purposes. ( Learn about spear phishing, a targeted phishing approach.) Insider threats and negligent employees Some attackers deliberately engineer phishing attacks to obtain data from particular users, like senior executives or well-known celebrities and politicians. If clicked, these files or links can easily infect a company's computer with malware that can propagate across a network. Phishing is an email-based social engineering attack that enables attackers to distribute malicious files or links via email. Social engineering and phishing are malicious techniques that deceive individuals into divulging confidential information or granting access to restricted systems. ![]() ( Compare threat detection with threat hunting.) Social engineering and phishing Detecting and preventing external attacks can be challenging, as attackers are constantly developing new methods and strategies to bypass security measures. External attacks and exploitationĮxternal attacks and exploitation involve threat actors exploiting vulnerabilities in a system to gain unauthorized access to sensitive data. To effectively prevent data exfiltration, organizations must be familiar with the common techniques threat actors employ. ![]() ( Learn how each of these play into the overall concept of InfoSec.) Common data exfiltration techniques To combat data exfiltration, you'll need to diligently invest in prevention measures including: The consequences of successful data exfiltration can be devastating. It can be done by both internal and external threat actors, leveraging various methods. Data exfiltration is the illicit transfer of sensitive data from an organization to unauthorized hands. ![]() What is data exfiltration?Īdata breach alone is a gateway to information theft. Let's have a closer look at what data exfiltration is. In this blog post, we will explore data exfiltration in-depth, discussing common techniques and best practices to ensure your organization's sensitive information remains secure. This nightmare can become a reality through data exfiltration.ĭata exfiltration is a real threat to organizations, as it involves the unauthorized transfer of sensitive information, the effects of which can lead to operational disruption, financial losses and damage to reputation. Imagine a scenario where a competitor gains access to your organization's most sensitive data, causing severe financial loss and irreparable damage to your reputation. ![]()
