Introduction
Reverse social engineering is a sophisticated tactic where the attacker creates a problem or need, then subtly guides the target into finding a solution that serves the attacker’s goals. This method is particularly effective because it manipulates the target into believing they have discovered the solution independently, thereby building trust in the attacker.
Creating a Need or Problem
When a social engineer cannot identify an existing need in the target, they create one. This can involve technical issues, fraudulent scenarios, or even direct attacks like malware. The attacker subtly introduces the problem through hints or implications, setting the stage for the target to seek assistance.
The Pretext and the Solution
Once the problem is introduced, the social engineer presents themselves as the solution provider, either directly or indirectly. The goal is for the target to believe they have discovered the solution themselves, which increases their trust in the attacker. This process often involves insinuation—planting ideas subtly through suggestive hints.
Example Scenario
In the provided example, a social engineer poses as a colleague familiar with the target’s boss, creating a fake problem involving missing documents. By appealing to the receptionist’s sympathy and professionalism, the attacker convinces them to insert a USB stick containing malware into the office computer. The entire scenario is carefully crafted, with the attacker guiding the target toward the desired action without directly stating it.
Conclusion
Reverse social engineering is a powerful method that exploits human psychology, particularly our desire to solve problems and help others. By carefully creating a scenario where the target feels in control of the solution, the attacker can effectively manipulate them into actions that compromise security.
