Case Study: Leading Energy Company thwarts a dictionary attack with Illusive

Energy Company - Customer Case Study

Leading Energy Company, a U.S. energy firm, faced the challenge of detecting a stealthy cyberattack hidden among false positives and alert fatigue. Using Illusive’s Attack Detection System, the company was able to spot suspicious failed login activity tied to a deceptive username deployed by Illusive.

Illusive’s solution exposed a broader dictionary attack, where scripted login attempts used generic usernames and passwords spread across the network to avoid detection. By identifying the attack early, the Leading Energy Company worked with Microsoft to review logs, locate the source, and completely eradicate the threat, preventing further damage.
