1. Vulnerability exploitation
Vulnerability exploitation is a critical component in the deployment of advanced surveillance tools through email-based attacks. It represents the method by which threat actors bypass security defenses to install malicious software, such as the aforementioned surveillance tool, onto a target’s device.
-
Zero-Day Exploits
Zero-day exploits involve leveraging software flaws that are unknown to the vendor, and for which no patch exists. In the context of email-based attacks, these exploits can be used to deliver a payload within an email message (or a link within) that, when processed by the email client or operating system, allows for the covert installation of malware. This eliminates the need for user interaction, making detection more challenging.
-
Email Client Vulnerabilities
Email clients, such as Outlook or Thunderbird, are complex software applications that can contain vulnerabilities. These weaknesses can be exploited to execute arbitrary code within the client, or to trigger actions that lead to the installation of malware. For example, a specially crafted email could exploit a vulnerability in the way the client handles certain file formats, leading to code execution when the email is opened or previewed.
-
Operating System Vulnerabilities
Email attacks often rely on vulnerabilities within the underlying operating system. A malicious email can be crafted to trigger a vulnerability in the OS’s image rendering engine or file handling routines. Successfully exploiting such flaws enables the attacker to gain control of the system without requiring the user to execute any specific actions.
