Rader's capture was significantly aided by digital forensics. He sent a floppy disk to the police, taunting them. This computer forensics services experts analyzed the disk and discovered metadata that led them to a computer at Rader's church. This evidence, combined with DNA analysis, led to his arrest and conviction. The digital forensic analysis provided the breakthrough needed to solve the cold case.
3. The Sony Pictures Hack
Overview:
In 2014, Sony Pictures Entertainment was the victim of a massive cyber attack. The hackers leaked confidential data, including unreleased films, employee information, and executive emails, causing significant damage to the company.
Role of Digital Forensics:
Digital forensics experts were called in to investigate the breach. They analyzed the malware used in the attack, traced the source of the hack, and identified the techniques employed by the attackers. The forensic analysis pointed to North Korean hackers, and the findings were supported by evidence such as IP addresses, malware signatures, and attack patterns. This case underscored the importance of digital forensics in cyber threat attribution and response.
4. The Silk Road Investigation
Overview:
Silk Road was an infamous online black market known for selling illegal drugs and other illicit goods. The website operated on the dark web and used Bitcoin for transactions. The FBI shut down Silk Road in 2013 and arrested its founder, Ross Ulbricht.
