Darktrace steps up cyber battle against digital fakes

Cyber AI specialist Darktrace has expanded its armoury to help clients thwart digital fakes. It has grown its platform to cover additional email systems including G Suite and Microsoft Exchange. 

The company’s Antigena Email, launched last year for Office 365, has proven a powerful defence against a wide variety of digital fakes as well as account hijacking, email spoofing, and targeted email attacks.

Today, 94 per cent of cyber-threats still originate in the inbox. 

‘Impersonation attacks’ are on the rise as AI is increasingly being used to automatically generate spear-phishing emails, or ‘digital fakes’ that expertly mimic the writing style of trusted contacts and colleagues. 

Humans can no longer distinguish real from fake on their own – as a result, artificial intelligence is increasingly being deployed to fight back against these advanced threats.åç

Darktrace’s AI forms an evolving understanding of normal user behaviour across a business’s diverse digital infrastructure, combining users’ network patterns and browsing behaviour with email communications and identity metrics for each individual in an organisation.

Armed with this rich knowledge, Antigena quickly and precisely fights back against email-based threats that bypass tools which only analyse email traffic. 

These include supply chain attacks, hijacked accounts, AI raids and other advanced forms of targeted attacks. In an era when thousands of documents can be encrypted in minutes, Antigena takes action in seconds – stopping cyber-threats before damage is done.

“Darktrace’s AI deals with the email security challenge in a way that goes far beyond basic security training for employees,” says Ian Golding, interim CIO at the Natural History Museum. 

“AI is always on and it doesn’t take breaks and so is consistently effective 24x7. Antigena Email is a clear winner in catching hoax emails before they get to the inbox, providing assurances to cyber teams and employees so they continue their work, uninterrupted.”

The Royal College of Surgeons is equally enthusiastic. Head of iT Mike Proudlock said: “Without artificial intelligence we would never have been able to spot the well-researched, targeted email attacks that threaten our organisation on a daily basis.

“A new age in cyber defence is just beginning and the effect of AI on this battleground is already proving fundamental.”

Marianaa Pereira, director of email security products at Darktrace says that until now email security was “the unsolved piece of the security puzzle.” 

She adds: “Attackers are getting smarter – using AI to generate ‘digital fakes’ that will be capable of exploding across supply chains – so defenders must urgently keep their executives, finance teams, and broader employee base safe. 

“Darktrace uniquely analyses all available data across cloud, email, and network to stop these targeted attacks before they do damage.”
