RetailGroupRecoversfromRansomwarein48HoursandAchievesCyberEssentialsCertification
A 30-staff Singapore retail group was crippled by ransomware on a Saturday night. MicroLogic contained the breach, restored operations in 48 hours, and guided them to Cyber Essentials certification within 6 weeks.
Results Achieved
!The Challenge
On a Saturday night, the client's point-of-sale systems across all four retail outlets went dark. A ransomware strain had encrypted the company's shared file server, backup drive, and two workstations. By Sunday morning, the owner had received a ransom demand for S$28,000 in cryptocurrency.
The client had no incident response plan, no offsite backup, and no dedicated IT security support — only a monthly IT maintenance contract with a vendor who wasn't answering calls. With stock audits, payroll, and supplier invoices locked inside encrypted files, the business faced an existential crisis.
✓The MicroLogic Solution
MicroLogic's 24/7 emergency line was called at 6:15am Sunday. A senior engineer was on-site by 9am. The response proceeded in three stages:
Containment (Day 1): Network isolation of all affected endpoints, forensic imaging of encrypted drives before any recovery attempt, identification of the attack vector (a phishing email that had been opened three days prior, with a delayed payload activation).
Recovery (Days 1–2): Clean OS reinstallation on affected machines, restoration from a partial cloud backup that had been overlooked, manual reconstruction of the remaining 11% of data from paper records and supplier statements. All four outlets were operational within 48 hours.
Hardening (Weeks 2–6): Following recovery, MicroLogic conducted a full Cyber Essentials gap assessment. Findings included unpatched firmware on 6 devices, no multi-factor authentication on email accounts, and default admin passwords on the network router. All 5 Cyber Essentials domains were remediated and the client achieved certification on first attempt.
“When ransomware hit us on a Saturday night, I thought it was the end of our business. MicroLogic had us back up and running by Monday morning. Now we have proper security in place and the Cyber Essentials certificate to prove it.”
