London, United Kingdom – British cyber security firm Darktrace on Wednesday warned that artificial intelligence bot ChatGPT may have increased the sophistication of phishing scams.
Content creation bot ChatGPT, Silicon Valley’s latest app sensation, was launched by Microsoft-backed start-up OpenAI in November.
“Darktrace does not believe that ChatGPT has yet lowered barriers to entry for threat actors significantly,” the firm said in a results statement.
“But it does believe that it may have helped increase the sophistication of phishing emails, enabling adversaries to create more targeted, personalised, and ultimately, successful attacks.”
Generative AI, of which ChatGPT is an example, can upon request wade through reams of data to conjure up original content — an image, a poem, a thousand-word essay — in seconds.
ChatGPT had “ignited a conversation about the implications of generative AI for cyber security”, Darktrace noted Wednesday.
It added however that email attacks on its customers were “steady” despite the release of ChatGPT, with a decline in the number of those containing malicious links.
Yet it warned that the “linguistic complexity” of those emails — including punctuation, sentence length and text volume — had increased.
“This indicates that cyber-criminals may be redirecting their focus to crafting more sophisticated social engineering scams that exploit user trust.”
Darktrace also revealed Wednesday that its net profit sank 86 percent to $581 million in the first half of its financial year, or six months to December.
Its performance was slammed by surging costs and tax charges.
Darktrace shares rose 1.2 percent to 267.10 pence in London midday deals, but the stock is down 40 percent compared with the same stage last year.
The company, which uses cutting-edge artificial intelligence technology to combat cyber attacks, floated on the London stock market in 2021.
However, shares have tumbled over the last year and a half on concerns over the group’s accounts, and after US private equity firm Thoma Bravo ended its takeover interest in 2022.
