This sounds like plot from scifi movie:
University of Washington researchers successfully stored malware in synthetic DNA strands, and used it to gain control of the computer analyzing it.
Researchers at the University of Washington have shown that by changing a little bit of computer code they can insert malware into a strand of DNA that, when read by DNA sequencing software, allows them to remotely control a computer or cause it to suddenly crash. Many vulnerabilities are present in other types of software.
The general security hygiene of bioinformatics programs is very low.
