Darktrace’s ‘digital antibodies’ fight unknown cybersecurity threats with machine learning

Darktrace has compared Antigena to the immune system of the human body. Image: Darktrace Cybersecurity firm Darktrace has launched new cyberdefence tool which it claims uses machine learning to automatically fight back against cybercrime threats, even if the malicious intrusion is previously unknown. The new product, Darktrace Antigena, uses machine learning to enable networks to automatically self-defend against potential threats without any prior knowledge of new attacks which might be used by hackers. By using machine learning techniques initially developed by mathematicians at the University of Cambridge, Darktrace — which was founded by former MI5 and GCHQ intelligence staff — claims that Antigena “replicates the function of antibodies in the human immune system” by detecting and tracking threats as they appear. Depending on the intrusion, Darktrace will respond by either…
