What happened

Researchers discovered a critical vulnerability in forensic software that allows undetectable modification of DNA samples from crime-scene evidence. An AI tool can modify or even switch DNA samples, with the vulnerability affecting evidence from the past 30 years.

Reported impact

The vulnerability places decades of DNA evidence at risk of tampering. The compromise could affect the integrity of criminal investigations and legal proceedings relying on the affected DNA evidence.

Index analysis

The vulnerability remained undetected for approximately 30 years of crime-lab operations. Digital signatures have reportedly been implemented by the responsible company to monitor for modifications as a remediation measure.

Governance controls

A patch is reportedly in the works to address the vulnerability. The company responsible for the software has stated that digital signatures have been implemented to detect modifications.
