Investigating and Eradicating Malware from a Healthcare System



The client provides healthcare services to outer-urban, regional and remote communities across 50 centres in Australia. 

The Challenge

Pragma was called to support the client on a technology issue with their network due to malware penetration, causing 600 workstations to be infected and damage to all operational servers in their datacentre. Due to the scale of the incident, a team of four Pragma consultants were assigned quickly to contain and remediate the impacted services. 

The Solution

Pragma performed a thorough investigation on the Client’s technology, event logs and identified the virus/malware point of entry was through a remote desktop and malicious website. Pragma confirmed the infection of the servers and advised the Client to disconnect from their network immediately to stop the virus/malware from spreading. A full virus scan removed 300+ viruses before installing new malware protection.


Eradication of Virus

Pragma efficiently deployed processes to identify, contain and eradicate the further spread of the virus.

Improved Security

All servers were hardened, and security measures were implemented that were originally lacking, (including but not limited to firewalls, monitoring and enterprise antivirus).

Resume Operations

The client’s data was fully recovered, and all 26 centres are now operational.

Due to non-disclosure agreements with our clients, we are unable to disclose clients’ real names in some of our case studies.
