A Step-by-Step Guide to Ransomware Remediation

Demystifying the recovery process post cyber attack

If you have fallen victim to a ransomware attack, all hope is not lost. By working quickly, with the support of Exponential-e’s trusted cyber security specialists, you can restore and secure your critical data in weeks rather than months.

CYBERSECURITY LANDSCAPE

Ransomware remains a lingering threat to organisations across the public and private sectors, from startups to industry leaders - with 66% of organisations experiencing an attack in 2023 alone.

It is therefore essential that your cyber security strategy not only utilises the latest solutions and threat intelligence to secure against attacks, but incorporates a robust remediation process, ensuring you are able to recover and resume trading as quickly as possible in the event of a successful attack, minimising the potential reputational and financial consequences.

The key to Successful Remediation

Falling victim to a security breach can be overwhelming, but understanding the recovery process can bring much-needed clarity and help you take proactive steps to getting operational again as quickly as possible. Due to the diverse nature of corporate infrastructure and the growing range of ransomware attacks utilised by bad actors, the process will vary every time, but the following steps are the key areas that a successful remediation will always incorporate, and form the core of Exponential-e’s own approach to disaster recovery.

The six pillars of effective ransomware recovery

01 - Initial steps

Initial steps

Time is of the essence! Upon receiving your call, our experts initiate immediate containment measures. We begin by isolating the infected device or network to prevent further encryption and lateral spread of the malware. Our team then meticulously gathers information about the attack, including infected files, ransom demands, and any available intelligence on the ransomware strain.

02 - Threat Identification and Eradication

Threat Identification and Eradication

The next step is in-depth forensic analysis. This involves:

  • Examining system logs and network traffic for suspicious activity.
  • Identifying the specific ransomware variant based on technical markers.
  • Determining the attack vector - how the malware gained access.

With the culprit identified, we deploy specialist tools and techniques to neutralise the threat. This may involve:

  • Terminating malicious processes and disabling associated scripts.
  • Executing rigorous malware removal across all infected systems.
  • Employing advanced anti-malware software for comprehensive system cleansing.
03 - Data Decryption

Data Decryption

The encrypted files hold the key to your precious data, which means they must be recovered and secured. We leverage:

  • Decryption keys - If available, we acquire decryption keys through various means, including collaboration with security researchers or negotiations with responsible disclosure platforms.
  • Decryption tools - We utilise advanced decryption tools, tailored to specific ransomware variants.

Throughout this process, we prioritise data integrity, ensuring recovered files remain unaltered and functional.

04 - System Restoration

System Restoration

With the threat neutralised and data recovered, we turn to restoring your systems to full functionality as soon as possible, allowing you to resume trading with minimal disruption. This involves:

  • Rebuilding compromised systems, potentially involving secure data wiping and clean installs.
  • Updating software and patching vulnerabilities that may have exploited.
  • Implementing robust security measures to prevent future intrusions.
05 - Vulnerability Assessment and Patching

Vulnerability Assessment and Patching

Effective remediation extends beyond an immediate recovery, focusing on the long-term protection of corporate infrastructure and the optimisation of the entire security ecosystem. To this end, our cyber security experts:

  • Conduct comprehensive vulnerability assessments to identify and prioritise remaining weaknesses.
  • Provide actionable recommendations for patching vulnerabilities, updating policies, and strengthening your overall security programme.
06 - Incident Response Training

Incident Response Training

To minimise the chances of future breaches occurring, and help cultivate a true cyber security culture across all levels of your organisation, we deliver hands-on incident response training, providing your teams with:

  • The ability to identify and contain the early warning signs of ransomware.
  • Best practice around reporting suspicious activity before it leads to a cyber attack.
  • The confidence to handle security incidents calmly and effectively, in line with corporate security policies.

A trusted partner throughout your ransomware mitigation journey

Throughout this journey, we maintain constant communication, keeping you informed about progress, potential challenges, and estimated recovery time. Our goal is to ensure you feel supported and empowered every step of the way, and that you finish the process with the systems, processes, and knowledge needed to secure against future threats.

Ransomware remediation is a complex process, and every attack presents unique challenges. However, with our proven expertise, advanced tools, and unwavering commitment to raising standards of cyber security across the public and private sectors, we are ready to ensure you can resume operations as quickly as possible, and - equally importantly - demonstrate your commitment to maintaining the integrity of your customers’ and end users’ critical data.
