Criminals sometimes damage their mobile phones in an attempt to destroy data.

Manufacturers use those taps to test their circuit boards, but by soldering wires onto them, forensic investigators can extract data from the chips.

Digital forensics experts can often extract data from damaged mobile phones using the JTAG method.

After the data extractions were complete, Ayers and Reyes-Rodriguez used eight different forensic software tools to interpret the raw data, generating contacts, locations, texts, photos, social media data, and so on.

The comparison showed that both JTAG and chip-off extracted the data without altering it, but that some of the software tools were better at interpreting the data than others, especially for data from social media apps.
