In the space of just a few short years, Artificial Intelligence (AI) has gone from being a somewhat niche field, to front and centre in the public consciousness. With the rise of ChatGPT and similar platforms, there is much speculation about where this technology is heading, and what its impact will be on our personal and professional lives. Indeed, organisations across numerous sectors are already exploring the different ways it can be utilised to reduce costs, optimise efficiency, and improve service quality.

On the 18th March 2024, the Information Commissioner's Office issued its updated guidance around the issuing of fines when organisations have been found liable for the integrity of their customers' or end users' data being compromised. It is already well-established now that failure to ensure critical data remains secure will result in costly fines, as we have seen repeatedly in multiple high-profile cases over the years.

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.

In light of numerous dramatic shifts in the geopolitical landscape in recent months, this blog has reiterated the need for organisations across all sectors to strengthen and - if necessary - reconsider their cyber security postures, in order to prepare for the anticipated attacks by global bad actors. The legal sector is no exception, particularly as these attacks are anticipated to specifically target the most high-value data.

To Test or Not to Test? - When it comes to IT disaster recovery and remediation processes, regular testing is not a 'nice to have' - it's absolutely essential!
This isn't hyperbole on my part. You just have to look at the news on any given day. We've all heard the horror stories of organisations in both the public and private sectors experiencing prolonged downtime during disasters due to inadequate preparation, lack of testing, and the unsuitability of their legacy remediation processes and systems.
