Everyone knows the importance of practising good cybersecurity, but we bet you never thought your computer could be hacked using DNA.

DNA is, at its heart, a system that encodes information in sequences of

programs, which can be used to reveal everything from one’s ancestry to fitness

nucleotides. Through trial and error, the team found a way to include executable

The researchers even went so far as to demonstrate a hacking technique might attempt — using biological molecules to infect a computer through normal DNA processing.

To create optimal conditions for an adversary, they introduced a known
