Researchers used AI-assisted code to undetectably tamper with data from computerized scans of physical DNA evidence produced by widely used crime-lab machines (Mariah Timms/Wall Street Journal)

Digital evidence systems that produce files from physical DNA scans have integrity vulnerabilities that AI-generated code can exploit without detection. For engineers building or auditing forensic data pipelines, this highlights that file-level integrity checks on digitized evidence may be insufficient against sophisticated tampering.
