The ransomware threat in Australia is constantly shifting as new criminal groups appear and established ones adapt their tactics.
Infosecurity have collected data from several sources to identify the Top 10 Most Active Ransomware Groups of 2024. Below is a list of the most prolific ransomware groups and their variants:
Threat actors gain access through entry points such as phishing emails, weak remote desktop protocols, or unpatched software flaws. In many cases, they compromise systems days or even weeks before deploying the ransomware.
After gaining entry, the attackers explore the network, targeting critical data for theft and disabling security software. They then encrypt key files, locking the organisation out of its own information.
Once the data is secured, the attackers deliver a ransom note, usually demanding cryptocurrency in return for a decryption key. Despite promises, paying rarely results in full data restoration.
With systems locked and files inaccessible, the organisation is effectively held hostage, essentially unable to operate normally or access essential data until recovery efforts begin.
Without a quick resolution, downtime extends, data may be permanently lost, and long-term reputational harm can follow. As such, the emphasis is on a quick response.
Leaders must act decisively: refuse payment, seek expert recovery support, and restore from secure backups. Every second wasted is more damage inflicted and increased loss of money and reputation.
Prevention is always more effective than cure. When an incident occurs, rapid detection and response are vital to limit damage. Involving professional ransomware recovery specialists ensures a structured investigation and a higher chance of safe restoration. Paying the ransom should remain a last resort, as there is no assurance your data will be returned.
