A cyberattack on Microlise, a key technology provider for UK fleet tracking, recently left many of its services offline. The incident affected tracking capabilities for more than 400 UK fleets, including 88% of UK grocery retailers and a majority of fleets with over 500 heavy goods vehicles (HGVs).

DHL, which relies on Microlise for real-time tracking services, confirmed that the cyberattack impacted deliveries to Nisa stores.

An interim system was implemented to provide updates and estimated arrival times every 15 minutes.

The Microlise board announced that it had engaged external cybersecurity specialists to investigate the incident and determine its extent. “The Microlise team is working hard to quickly bring the affected services back online,” the company stated.

The company has also notified regulators, including the Information Commissioner’s Office in the UK, and is in discussions with its cyber insurance provider.

“We are mindful of our obligations regarding data; it is too soon yet to make any determination around the impact this incident has had on personal data, but we will inform any individuals in line with our regulatory obligations should there be a need to do so,” Microlise noted in a statement.

DHL has implemented precautionary safeguarding measures to maintain service continuity.

“DHL Supply Chain UK is aware of a downtime incident impacting Microlise, a third-party supplier which we use. We can confirm this incident has not affected DHL-owned systems,” a DHL spokesperson told Better Retail, emphasizing that the issue is isolated to Microlise.

The company added that it has “implemented contingencies to ensure that service levels are maintained for those customers who may be potentially impacted.”

Microlise expressed gratitude to its customers for their “patience and understanding” while it focused on restoring its services following the cyberattack.
