DNA Test Files From Thermo Fisher Equipment Found Vulnerable to Tampering
The flaw undermines the integrity of DNA evidence used in criminal investigations, as tampered files can be made to appear unchanged since 2025.
Reporting from 1 source: GIGAZINE.
A vulnerability in Thermo Fisher Scientific DNA testing equipment allows tampering with test result files that is undetectable by analysis software. Engineer Nathan Adams demonstrated the flaw using Claude. Thermo Fisher disclosed the issue on July 31, 2026, and released a security update, recommending encrypted storage and access restrictions for those who cannot update.
Thermo Fisher Scientific disclosed a vulnerability in its DNA testing equipment on July 31, 2026, after engineer Nathan Adams of Forensic Bioinformatics demonstrated that test result files could be tampered with undetectably. Adams used Claude to combine two DNA test results into a new one that analysis software read as normal, with the system falsely recognizing that nothing had changed since 2025.
The Wall Street Journal reported the flaw, which Adams reported to Thermo Fisher in May 2026. For users who cannot apply the security update, Thermo Fisher recommends storing generated files in encrypted storage, restricting file access, and reviewing firewall settings to limit internet connections to trusted sources.
