Adam works as a Security Administrator for Umbrella Technology Inc. He reported a breach in security to his senior members, stating that "security defenses has been breached and exploited for 2 weeks by hackers." The hackers had accessed and downloaded 50,000 addresses containing customer credit cards and passwords. Umbrella Technology was looking to law enforcement officials to protect their intellectual property.
The intruder entered through an employee's home machine, which was connected to Umbrella Technology's corporate VPN network. The application called BEAST Trojan was used in the attack to open a "back door" allowing the hackers undetected access. The security breach was discovered when customers complained about the usage of their credit cards without their knowledge.
The hackers were traced back to Shanghai, China through e-mail address evidence. The credit card information was sent to that same e-mail address. The passwords allowed the hackers to access Umbrella Technology's network from a remote location, posing as employees.
