AI-Assisted Code Can Undetectably Tamper with DNA Evidence Scans, Exposing Forensic Vulnerabilities

Researchers have demonstrated that AI-assisted code can undetectably manipulate data from computerized scans of physical DNA evidence, which are produced by widely used crime-lab machines. This finding, reported by the Wall Street Journal, exposes critical chain-of-custody assumptions that have underpinned approximately 30 years of forensic casework, raising concerns as courts increasingly deal with AI-generated and AI-manipulated evidence in criminal proceedings.
