Security teams urged to prepare for next era of ransomware

Global cybersecurity firm Trend Micro has published a new report warning that the ransomware industry could be on the verge of a revolution that sees actors expand into other areas of cybercrime or partner with hostile governments and organised crime groups.

Cybersecurity professionals are not new to the concept of ransomware – a menace that has long since plagued businesses, organisations, and governments alike. 

In response to corporate defensive strategies, law enforcement successes, and government sanctions, threat actors are likely to get more sophisticated and scale up their attacks through increased automation and a shift in business models. The latter is likely to take shape in the form of the development of supply chain attacks, trading of services to organised crime syndicates, or partnerships with government actors, among others.

These scenarios could have a particularly devastating effect on IoT and cloud environments and create an urgent need for network defenders and governments to ready themselves.

"Change is the only constant in cybercrime, and sooner or later, economic and geopolitical forces may compel ransomware groups to adapt or die," says Jon Clay, Vice President of Threat Research at Trend Micro.

"Amidst this uncertain threat landscape, network defenders need platform-based security to provide visibility and control across all attack surfaces, including hybrid cloud infrastructure. Our latest report will help them prepare for the future," he says.

The report highlights the history of ransomware and the key building blocks of modern attacks before proposing scenarios that show where threats may be evolving.

Threat actors will continue to evolve their attacks in response to corporate defensive strategies, law enforcement successes, and government sanctions. This could include scaling up attacks through increased automation, targeting more IoT and cloud environments, improving professionalism and execution, and more effectively monetising attacks.

The report also predicts that ransomware actors will eventually be motivated to change their business models due either to the cumulative impact of relatively small changes or by more radical global factors. This could lead to them developing supply chain attacks to cut out reliance on initial access brokers, using stolen data for stock manipulation, selling more services to traditional organised crime syndicates, merging with other criminal groups, or even working with government actors.

There is no silver bullet to solve these challenges. As they emerge, network defenders and governments should tackle changes to cybercrime business models. Trend Micro's report also provides a set of potential actions to prepare for these scenarios, including hardening internet-facing and internal corporate systems, migrating to cloud services, focusing defensive efforts on detection and response and initial access vectors, strengthening government sanctions on major actors and facilitators, and regulating cryptocurrency to increase transparency, protect consumers against fraud and make money laundering harder.
