LinkedIn to Your Network - The Social Engineering Threat


Published on

By nature, humans are inclined to trust. Unfortunately, attackers are often successful in breaching large enterprises by targeting specific individuals and utilizing social engineering to obtain confidential information. Once an adversary is able to gain enough data through social media or other channels, they can pose as an authentic user with valid credentials, bypassing traditional security measures.

Join Lancope’s Joey Muniz, aka The Security Blogger, to hear about his successful, real-life experiments in using social engineering to easily compromise high-profile targets.

Learn about:

· The dangers of insider threats

·How attackers are leveraging social media to compromise targets

· Best practices for defending network interiors from attackers with authentic credentials
