The Challenge
In Q3 of 2024, the CEO of a UK-based bank received an email from a ransomware group, informing him that the bank's data had been encrypted and would be released on the dark web unless a ransom demand was paid. Although several insurers and consultants were engaged to resolve the situation, the slow response times made it clear that an alternative approach would be needed.
Finally, in order to minimise the resulting downtime and resume operations as soon as possible, without giving in to the criminals' ransom demand, the organisation engaged Exponential-e to restore and secure their critical servers. With even the shortest period of downtime resulting in serious financial and reputational damage, a team of incident response specialists immediately began the restoration process, aiming to have the bank's systems back online in days rather than weeks.
The Solution
The restoration process began with a thorough audit of the IT ecosystem to establish which servers had been impacted, after which the affected VMs were powered down. A new, fully isolated VDC was created to store these VMs once they were recovered, along with a completely new firewall zone.
With the affected servers restored into this new VDC zone, firewalls were established to allow for the most basic access, after which malware scans were conducted. These scans continued for two days, during which the customer was granted initial access to the servers via a temporary SSL VPN with Azure MFA, allowing them to resume operations in just three days.
At this point, Zerto replication was set up for the new VMs, while Exponential-e simultaneously engaged with the third party that was conducting a forensic investigation.
Connectivity was soon re-established for the customer's other offices, at which point users were brought back online. Firewall logs were provided for the forensic team, along with initial access to VM images via vCloud Director.
Finally, a test rebuild of the affected VMs was conducted and finalised within two days, and additional firewall policies established.
Exponential-e has repeated variations of this process for multiple other organisations affected by ransomware attacks, allowing them to resume operations as quickly as possible and ensure their critical infrastructure is secured against future attacks.
The Result
Ongoing communication between all parties involved ,including a dedicated team of incident response specialists at Exponential-e with a defined action plan ensured a seamless restoration process. Day-to-day operations resumed in just seven days, without paying the criminals' ransom demand.
Don't wait for a crisis to expose the cracks, fortify your defences today. Discover how expert response turned seven days of chaos into operational recovery.
