Anatomy of a Social Engineering Attack Cycle
A typical social engineering engagement involves four key phases: reconnaissance, engagement, exploitation, and closure. The attacker uses social skills to obtain or compromise an organization’s assets during these stages.
The reconnaissance phase involves collecting necessary information to plan and execute the engagement effectively. Social engineers gather data from technical sources, physical sources, and even dumpster diving to familiarize themselves with the target environment and identify potential vulnerabilities .
During the engagement phase, the social engineer interacts with the target to build rapport and gain enough access or knowledge to move forward. This can be done through various methods such as phishing, spear phishing, vishing, SMiShing, and impersonation.
| Engagement MethodDescription | |
| Phishing | Mass emails sent to infect devices or retrieve credentials |
| Spear Phishing | Targeted emails to infect systems or retrieve credentials |
| Vishing | Phone calls used to gain access or information |
| SMiShing | SMS text messages used for social engineering |
| Impersonation | Acting in person with a thoroughly crafted pretext |
The exploitation phase is where the attacker achieves their goal, assuming the previous steps were successful. This could involve extracting information or gaining access to a specific room or machine .
Finally, the closure phase involves ending the engagement without arousing suspicion. The social engineer must disengage naturally to avoid detection . Analyzing how the organization detects past incidents is also important for assessing their security posture.

The convergence of AI and quantum computing has facilitated the emergence of deepfakes, which are videos or audio recordings manipulated using AI to make it appear as though someone is saying or doing something they are not . Deepfake attacks represent an advanced method of social engineering that, as of now, has been infrequently encountered in real-world scenarios . However, even for those with a solid security framework, deepfake technology is improving rapidly and becoming increasingly cost-effective and accessible .
Augmented reality (AR) and virtual reality (VR) also present security and privacy risks. AR collects a lot of information about who the user is and what they are doing – to a much greater extent than other forms of technology . This raises concerns about how AR companies use and secure the information they have gathered from users . VR security threats are slightly different from AR since VR is limited to closed environments and doesn’t involve interactions with the real physical world . However, VR headsets cover the user’s entire vision, which can be dangerous if hackers take over the device .
| VR Privacy Issue Description | |
| Finger tracking | The system records and transmits finger tracking data showing fingers typing a PIN |
| Eye-tracking | Knowing precisely what a user is looking at could reveal valuable information to an attacker |
Quantum computing presents a paradigm shift, providing hackers with unprecedented computational capabilities to break encryption and access sensitive data . Quantum computing can crack widely used encryption methods, rendering sensitive data vulnerable to unauthorized access . The development of quantum-safe cryptographic solutions becomes imperative to mitigate the vulnerabilities introduced by quantum computing, requiring proactive measures to secure digital infrastructure.
