Ransomware Incident Response And Recovery For A Logistics Group

The first hour decides how bad an incident becomes. We joined the group's leadership on a call within 20 minutes, set up a clear command structure and began gathering facts about what was affected, how the attack was spreading and which systems were still safe. Every minute of delay was costing the business real money.

Remote responders deployed endpoint detection tools across the estate while the on-site team was travelling. Within 90 minutes, we had identified the ransomware family, the main spreading method through network file shares and the accounts the attackers were using, giving us a clear plan for stopping the attack before it reached the remaining hubs.

Clear triage prevented panic-driven decisions, such as wiping systems that held vital evidence. Every action from that point was logged with a timestamp and owner, creating a reliable record for insurers, regulators and the lessons-learned review after the incident. The same structured approach now forms the first page of the group's formal incident response plan.

Containment focused on cutting off the attacker's routes without shutting the whole business down. We segmented the network between hubs, blocked the file-sharing traffic the ransomware was using and isolated infected machines remotely through the endpoint tools. Business leaders approved each step before it was taken.

Compromised accounts were disabled, all privileged passwords were reset in a controlled sequence and the attacker's remote access tools were blocked at the firewall. Unaffected hubs were kept running on isolated network segments, so deliveries could continue in most regions while the recovery work focused on the sites that had been hit hardest.

The attack was fully contained within six hours, and no further hubs were affected after the first morning. That speed limited the damage to 12 of the 40 sites and gave the recovery team a stable, safe environment to work in from then on. Temporary controls stayed in place until recovery was complete, then were reviewed and made permanent where useful.

While systems were being contained, our forensic team worked out exactly how the attackers got in and what they did. Memory, disk images and logs were preserved using proper chain-of-custody procedures, so the evidence would stand up to legal scrutiny if needed. Every step was carefully documented for later review.

The investigation traced the initial access to a phishing email opened nine days earlier, followed by credential theft and slow, careful movement through the network. It also confirmed that a small amount of data had been copied out before encryption began, which shaped the group's regulatory notifications and customer communications from that point on.

Knowing the full attack path meant every door the attackers had used could be closed before systems were restored. The detailed forensic report also supported the group's insurance claim and was shared with law enforcement to help with their wider investigation. The findings also shaped the long-term improvement plan, making sure every weakness the attackers used was fixed.

Recovering without paying a ransom depended entirely on the backups, which had not been tested in eight months. Our first priority was to find out whether they were complete, uncorrupted and free from any hidden malware planted by the attackers. The whole recovery plan depended on what we found.

We isolated the backup environment and checked each backup set against the timeline from the forensic investigation, choosing restore points from before the attackers first arrived. Test restores of critical systems were carried out in a sealed environment and scanned thoroughly, confirming the data was clean before anything touched the production network.

Clean, usable backups were confirmed within four hours, which allowed the leadership team to reject the ransom demand with confidence. Without that validation, the group would have faced a much harder decision under enormous time pressure and cost. Backups are now tested every month, so the group will never again be unsure whether it can recover.

Restoration followed a carefully planned order based on business impact. Identity systems came first, followed by the warehouse management and routing platforms that kept trucks moving, then finance, email and all remaining back-office systems. The order was agreed with operations leaders in advance.

Every restored system was rebuilt from clean images, patched, hardened and monitored closely before being reconnected to the network. Hubs were brought back online in waves, with local teams confirming that scanners, printers and handheld devices were working properly before we moved on to the next group of sites in the plan.

All 40 hubs were fully operational within 72 hours of the first call, far faster than the weeks many businesses face after a similar attack. Customer deliveries caught up within a few days, and no hub needed to be restored a second time. Detailed recovery runbooks were written from the experience, so any future restoration could be even faster.

An incident like this is as much about trust as technology. We worked alongside the group's executives from the first morning, helping them decide what to say, when to say it and who needed to hear it first. Every message was reviewed with legal advisers first.

We drafted clear, honest updates for staff, customers, partners and the media, avoiding speculation while showing that the situation was under control. Regulatory notifications to the data protection authority were prepared and filed within the required 72-hour window, supported by evidence from the forensic investigation and legal advice.

Customers praised the group's transparency, and no major contracts were lost as a result of the incident. Handling communications well turned what could have been a reputational disaster into a story about a business that responded calmly and professionally. The communication templates created during the incident are now part of the group's crisis plan.

Ransomware groups often leave behind backdoors so they can return later. Once operations were restored, we carried out a thorough threat hunt across every system to make sure the attackers were completely gone from the environment. Every system on the network was included in the search.

Our hunters searched for hidden accounts, scheduled tasks, unusual services and suspicious connections, using the attack patterns found during the investigation as a guide. Two additional backdoors were discovered on systems that had not been encrypted and were removed before they could be used to launch a second attack on the group.

The hunt gave the leadership team confidence that the environment was truly clean. Continuous monitoring was kept in place for 30 days afterwards, and no further malicious activity was detected during that period or in the months that followed. Quarterly threat hunts are now part of the group's ongoing security service, providing continued assurance.

Recovery was only the first step. We worked with the group to make sure a similar attack could never succeed so easily again, turning the lessons from the incident into a practical, funded security improvement plan. The board sponsored the programme from the very start.

Multi-factor authentication was enforced everywhere, network segmentation between hubs was made permanent, and backups were redesigned with immutable, offline copies tested every month. A written incident response plan was created and rehearsed, so staff now know exactly what to do and who to call if something goes wrong in future.

The group now retains us as its 24/7 incident response partner, with a guaranteed 30-minute response time. Its security posture is stronger today than before the attack, and the board treats cyber resilience as a core part of business continuity. A tabletop exercise six months later showed the team could now respond to a similar attack with real confidence.
