A data breach had occurred! And a small local business was involved. The company had reported unusual activity on their network and suspected that an employee might be involved in unauthorized access. Samuel, a junior digital forensics analyst at Cyber Juice, was assigned the case.
As the young professional delved into the investigation, he meticulously combed through network logs, system files, and email communications. While the case initially appeared straightforward, Samuel’s attention to detail led him to uncover a series of suspicious login attempts originating from an employee’s workstation.
What started as a routine investigation took an unexpected turn when analysis revealed the employee’s credentials had been compromised, allowing an external attacker to gain unauthorized access to the company’s network. Samuel traced the source of the breach to a phishing email that had tricked the employee into divulging their login credentials.
Further investigation also uncovered an anomaly in the timestamps of the compromised login attempts. Despite appearing to originate from the employee’s workstation, the timestamps didn’t align with the employee’s typical working hours.
Curious, the analyst dug deeper and discovered evidence of remote access software installed on the employee’s computer. It turned out that the attacker had used this software to remotely control the workstation during off-hours, making it appear as tough the employee was responsible for the unauthorized access.
Samuel made a detailed documentation of his findings and presented them to his senior colleagues and the company’s management. Thanks to keen observation and thorough analysis, the company was able to prevent implement additional security measures to prevent similar incidents in the future. This minor forensic investigation not only resolved the immediate security issue but also highlighted the importance of meticulous examination and attention to detail in digital forensic.
