Extraction of data
The Cyber Security Officer told the court that he called his team of officers and “we set out to do an extraction on the electronic devices.”
The witness said, “each device was connected to the extraction machine and we intrigued the machine to extract the materials or data.”
He told the court that, out of the 13 devices, 11 of them were successfully extracted.
But, two of them – Samsung notebook 2 and iPad mini were not accessible to the extraction device.
The NIB officer told the court that the data extracted includes call logs, contacts, pdf files, word files, audio, video, and WhatsApp chats.
He said all of this extracted data was put in an external hard drive while all the phones were put back in an envelope and sealed.
He then issued a report and submitted it to the investigation department of NIB through the Director.
He told the court that after the investigation team had analyzed the data, they again requested that the extraction team of the technical department print the same data from the hard drive.
“This data was found on Samsung Galaxy S7 and was the only phone that had data relevant to the investigation team’s case. The technical team went ahead to print the data.
“This data was WhatsApp chats between Dr. Frederick Mac-Palm and some numbers saved as ACP Dr. Benjamin, Dr. Sam, Zikpi gam, and a WhatsApp group by name Take Action Ghana Executive platform.
He said all year data was found on the Samsung Galaxy S7 phone belonging to Dr. Frederick MacPalm.
The extraction team went ahead to print out the chats without media because they requested for only chat and per the extraction device media files are separated from chats.
