Menace actors have deviated from big-batch assaults to concentrate on a narrower vary of extra profitable targets.
Synthetic intelligence is a recreation changer in cyber safety, with cyber criminals exploiting AI to launch refined focused assaults and organisations wanting to make use of the rising know-how to strengthen defence.
That is in response to the Trend Micro 2023 Annual Cybersecurity Report, primarily based on enter from the cyber safety agency’s business and client shoppers.
The report, formally launched in Johannesburg this week, reveals that risk actors have deviated from big-batch assaults to concentrate on a narrower vary of extra profitable targets – and AI is central to those assaults.
“Whereas risk actors are utilizing AI to extend the speed and class of assaults, defence wish to use it to cut back the time taken to reply,” says Gareth Redelinghuys, nation managing director, African Cluster at Development Micro.
IT leaders should refine their processes and protocols to allow their defences to fight persistence with effectivity.

“Our newest knowledge reveals that risk actors are fine-tuning their operations, shifting away from large-scale assaults, and as a substitute specializing in a smaller vary of targets however with greater sufferer profiles for max acquire with minimal effort. As they proceed to double down on tried and examined strategies, they’re additionally delegating and streamlining operations – leading to bolder, simpler strikes,” says Redelinghuys.
In line with Development Micro, using GenAI in phishing makes an attempt is already branching past e-mails and texts to incorporate persuasive audio and video ‘deepfakes’ for an much more business-affecting risk.
“Think about an organization that requires dwell voice authorisation for purchases above one million {dollars}, for instance. An attacker may ship a real-seeming electronic mail request with a rigged telephone quantity embedded and reply the affirmation name with a deepfaked voice to validate the transaction. These new techniques introduce the potential for every part from inventory market manipulations to democratic or wartime disinformation campaigns, or smear assaults on public figures,” Redelinghuys provides.
The obstacles to entry for strategies like these have dropped with the rise of available app-style interfaces just like the AI-powered video creation software HeyGen, the safety firm factors out.
The report notes that AI clears the best way for beginner cyber criminals, whereas creating novel playgrounds for seasoned actors. Cyber criminals with no coding data or particular computing sources can produce customised high-resolution outputs which might be humanly undetectable.
Excessive-value targets over quantity
Development Micro claims to have blocked greater than 159 million e-mail threats, round 8 million malicious URLs and over 22 million malicious cell apps focused at South African companies and shoppers throughout 2023.
Nearly 40 000 ransomware assaults have been additionally blocked by the corporate in South Africa in 2023. Nonetheless, year-on-year analysis reveals that ransomware teams are working smarter as a substitute of tougher, prioritising high-value targets over quantity.
Different rising threats embody the appliance of malicious knowledge into authentic AI bots – or poisoned knowledge – that forces an override of authentic knowledge and allows simple entry into methods, in addition to tailored worms and ‘jail breaking’ to govern the LLMs inside AI.
Zaheer Ebrahim, options srchitect, Center East, and Africa at Development Micro, says, “Our analysis reveals that these more and more refined assaults are going to grow to be increasingly tough for companies to detect and that they are going to be more and more pricey after they succeed. IT leaders should refine their processes and protocols to allow their defences to fight persistence with effectivity.”
The corporate continues to advocate elevated cyber safety coaching and consciousness initiatives, common backups, a zero-trust strategy, and robust authentication mechanisms.
