When the Washington Examiner wanted to learn if the copy of a hard drive they received was owned and used by Hunter Biden, they turned to Konstantinos “Gus” Dimitrelos, a former Secret Service agent who has testified as a cyberforensics expert in over 100 classified, criminal, and civil matters at the state, federal, and international levels. Using an in-depth method he created called “digital sandwiching,” Dimitrelos was able to conclude that the hard drive was 100% authentic.
An excerpt from the Washington Examiner piece on the hard drive follows:
“My analysis revealed there is a 100% certainty that Robert Hunter Biden was the only person responsible for the activity on this hard drive and all of its stored data,” Dimitrelos said, noting that his forensic techniques are reproducible and are the same that he frequently uses as an expert when working on criminal and civil cases.
“Hunter Biden’s MacBook Pro was not hacked, and the data contained on the hard drive is authentic,” Dimitrelos added. “Based on the data I examined, there was no manipulation of any photographs, emails, documents, or other user activities.”
The laptop became the subject of intense scrutiny in 2020, after a federal investigation into Hunter Biden’s taxes was announced. The investigation is ongoing, and multiple media outlets have made efforts to authenticate copies of the hard drive. The Washington Examiner sought Dimetrelos’ expertise on data authenticity and cyber security.
“The data contained within the notes are preserved and protected within the iCloud backups and are not being shared with any other persons,” Dimitrelos said. “Data within the notes is also unique to Robert Hunter Biden, which is another fact connecting the Macbook Pro Laptop to Robert Hunter Biden and only him.”
Dimitrelos used multiple authentication methods, including DomainKeys Identified Mail, or DKIM, to provide email verification. He also analyzed metadata tied to various photos of Hunter Biden’s identification cards, such as his driver’s license and credit cards. Additionally, Dimetrelos authenticated Biden’s signature on various documents stored on the hard drive. After conducting this thorough investigation, he determined that the laptop had only been owned and accessed by Biden.
“DKIM verification is only a portion of authenticating email integrity,” Dimitrelos said. “There were hundreds of unique identifiers showing Robert Hunter Biden is the only user of the laptop. There were also thousands of iPhone photographs and videos taken by RHB including personal ones, RHB identification cards, travel documents, credit cards, business and financial transactions.”
Dimitrelos and other experts at Cyber Forensics continue to use similar methods to assist clients with a variety of cybersecurity needs. They also perform cellular triangulation, forensic training, and electronic discovery. Cyber Forensics analysts can give expert testimony in court cases and step in when clients need help recovering from a data breach or hack. In addition, they have provided expert witness services for a wide variety of high profile clients. In 2021, Dimetrelos was interviewed by ABC Action News in Florida prior to the Super Bowl about security for the big event.
